A cybercriminal group that used voice phishing attacks to siphon more than a billion records from Salesforce customers earlier this year has launched a website that threatens to publish data stolen from dozens of Fortune 500 firms if they refuse to pay a ransom. The group also claimed responsibility for a recent breach involving Discord user data, and for stealing terabytes of sensitive files from thousands of customers of the enterprise software maker Red Hat.

In May 2025, a prolific and amorphous English-speaking cybercrime group known as ShinyHunters launched a social engineering campaign that used voice phishing to trick targets into connecting a malicious app to their organization’s Salesforce portal.

The first real details about the incident came in early June, when the Google Threat Intelligence Group (GTIG) warned that ShinyHunters — tracked by Google as UNC6040 — was extorting victims over their stolen Salesforce data, and that the group was poised to launch a data leak site to publicly shame victim companies into paying a ransom to keep their records private. A month later, Google acknowledged that one of its own corporate Salesforce instances was impacted in the voice phishing campaign.

Last week, a new victim shaming blog dubbed “Scattered LAPSUS$ Hunters” began publishing the names of companies that had customer Salesforce data stolen as a result of the May voice phishing campaign.

“Contact us to negotiate this ransom or all your customers data will be leaked,” the website stated in a message to Salesforce. “If we come to a resolution all individual extortions against your customers will be withdrawn from. Nobody else will have to pay us, if you pay, Salesforce, Inc.”

Below that message were more than three dozen entries for companies that allegedly had Salesforce data stolen, including Toyota, FedEx, Disney/Hulu, and UPS. The entries for each company specified the volume of stolen data available, as well as the date that the information was retrieved (the stated breach dates range between May and September 2025).

On October 5, the Scattered LAPSUS$ Hunters victim shaming and extortion blog announced that the group was responsible for a breach in September involving a GitLab server used by Red Hat that contained more than 28,000 Git code repositories, including more than 5,000 Customer Engagement Reports (CERs).

“Alot of folders have their client’s secrets such as artifactory access tokens, git tokens, azure, docker (redhat docker, azure containers, dockerhub), their client’s infrastructure details in the CERs like the audits that were done for them, and a whole LOT more, etc.,” the hackers claimed.

Their claims came several days after a previously unknown hacker group calling itself the Crimson Collective took credit for the Red Hat intrusion on Telegram.

Red Hat disclosed on October 2 that attackers had compromised a company GitLab server, and said it was in the process of notifying affected customers.

“The compromised GitLab instance housed consulting engagement data, which may include, for example, Red Hat’s project specifications, example code snippets, internal communications about consulting services, and limited forms of business contact information,” Red Hat wrote.

Separately, Discord has started emailing users affected by another breach claimed by ShinyHunters. Discord said an incident on September 20 at a “third-party customer service provider” impacted a “limited number of users” who communicated with Discord customer support or Trust & Safety teams. The information included Discord usernames, emails, IP address, the last four digits of any stored payment cards, and government ID images submitted during age verification appeals.

The Scattered Lapsus$ Hunters claim they will publish data stolen from Salesforce and its customers if ransom demands aren’t paid by October 10. The group also claims it will soon begin extorting hundreds more organizations that lost data in August after a cybercrime group stole vast amounts of authentication tokens from Salesloft, whose AI chatbot is used by many corporate websites to convert customer interaction into Salesforce leads.

In a communication sent to customers today, Salesforce emphasized that the theft of any third-party Salesloft data allegedly stolen by ShinyHunters did not originate from a vulnerability within the core Salesforce platform. The company also stressed that it has no plans to meet any extortion demands.

“Salesforce will not engage, negotiate with, or pay any extortion demand,” the message to customers read. “Our focus is, and remains, on defending our environment, conducting thorough forensic analysis, supporting our customers, and working with law enforcement and regulatory authorities.”

The GTIG tracked the group behind the Salesloft data thefts as UNC6395, and says the group has been observed harvesting the data for authentication tokens tied to a range of cloud services like Snowflake and Amazon’s AWS.

Google catalogs Scattered Lapsus$ Hunters by so many UNC names (throw in UNC6240 for good measure) because it is thought to be an amalgamation of three hacking groups — Scattered Spider, Lapsus$ and ShinyHunters. The members of these groups hail from many of the same chat channels on the Com, a mostly English-language cybercriminal community that operates across an ocean of Telegram and Discord servers.

The Scattered Lapsus$ Hunters darknet blog is currently offline. The outage appears to have coincided with the disappearance of the group’s new clearnet blog — breachforums[.]hn — which vanished after shifting its Domain Name Service (DNS) servers from DDoS-Guard to Cloudflare.

But before it died, the websites disclosed that hackers were exploiting a critical zero-day vulnerability in Oracle’s E-Business Suite software. Oracle has since confirmed that a security flaw tracked as CVE-2025-61882 allows attackers to perform unauthenticated remote code execution, and is urging customers to apply an emergency update to address the weakness.

Mandiant’s Charles Carmakal shared on LinkedIn that CVE-2025-61882 was initially exploited in August 2025 by the Clop ransomware gang to steal data from Oracle E-Business Suite servers. Bleeping Computer writes that news of the Oracle zero-day first surfaced on the Scattered Lapsus$ Hunters blog, which published a pair of scripts that were used to exploit vulnerable Oracle E-Business Suite instances.

On Monday evening, KrebsOnSecurity received a malware-laced message from a reader that threatened physical violence unless their unstated demands were met. The missive, titled “Shiny hunters,” contained the hashtag $LAPSU$$SCATEREDHUNTER, and urged me to visit a page on limewire[.]com to view their demands.

KrebsOnSecurity did not visit this link, but instead forwarded it to Mandiant, which confirmed that similar menacing missives were sent to employees at Mandiant and other security firms around the same time.

The link in the message fetches a malicious trojan disguised as a Windows screensaver file (Virustotal’s analysis on this malware is here). Simply viewing the booby-trapped screensaver on a Windows PC is enough to cause the bundled trojan to launch in the background.

Mandiant’s Austin Larsen said the trojan is a commercially available backdoor known as ASYNCRAT, a .NET-based backdoor that communicates using a custom binary protocol over TCP, and can execute shell commands and download plugins to extend its features.

“Downloaded plugins may be executed directly in memory or stored in the registry,” Larsen wrote in an analysis shared via email. “Capabilities added via plugins include screenshot capture, file transfer, keylogging, video capture, and cryptocurrency mining. ASYNCRAT also supports a plugin that targets credentials stored by Firefox and Chromium-based web browsers.”

Malware-laced targeted emails are not out of character for certain members of the Scattered Lapsus$ Hunters, who have previously harassed and threatened security researchers and even law enforcement officials who are investigating and warning about the extent of their attacks.

With so many big data breaches and ransom attacks now coming from cybercrime groups operating on the Com, law enforcement agencies on both sides of the pond are under increasing pressure to apprehend the criminal hackers involved. In late September, prosecutors in the U.K. charged two alleged Scattered Spider members aged 18 and 19 with extorting at least $115 million in ransom payments from companies victimized by data theft.

U.S. prosecutors heaped their own charges on the 19 year-old in that duo — U.K. resident Thalha Jubair — who is alleged to have been involved in data ransom attacks against Marks & Spencer and Harrods, the British food retailer Co-op Group, and the 2023 intrusions at MGM Resorts and Caesars Entertainment. Jubair also was allegedly a key member of LAPSUS$, a cybercrime group that broke into dozens of technology companies beginning in late 2021.

In August, convicted Scattered Spider member and 20-year-old Florida man Noah Michael Urban was sentenced to 10 years in federal prison and ordered to pay roughly $13 million in restitution to victims.

In April 2025, a 23-year-old Scottish man thought to be an early Scattered Spider member was extradited from Spain to the U.S., where he is facing charges of wire fraud, conspiracy and identity theft. U.S. prosecutors allege Tyler Robert Buchanan and co-conspirators hacked into dozens of companies in the United States and abroad, and that he personally controlled more than $26 million stolen from victims.

Update, Oct. 8, 8:59 a.m. ET: A previous version of this story incorrectly referred to the malware sent by the reader as a Windows screenshot file. Rather, it is a Windows screensaver file.

U.S. prosecutors last week levied criminal hacking charges against 19-year-old U.K. national Thalha Jubair for allegedly being a core member of Scattered Spider, a prolific cybercrime group blamed for extorting at least $115 million in ransom payments from victims. The charges came as Jubair and an alleged co-conspirator appeared in a London court to face accusations of hacking into and extorting several large U.K. retailers, the London transit system, and healthcare providers in the United States.

At a court hearing last week, U.K. prosecutors laid out a litany of charges against Jubair and 18-year-old Owen Flowers, accusing the teens of involvement in an August 2024 cyberattack that crippled Transport for London, the entity responsible for the public transport network in the Greater London area.

On July 10, 2025, KrebsOnSecurity reported that Flowers and Jubair had been arrested in the United Kingdom in connection with recent Scattered Spider ransom attacks against the retailers Marks & Spencer and Harrods, and the British food retailer Co-op Group.

That story cited sources close to the investigation saying Flowers was the Scattered Spider member who anonymously gave interviews to the media in the days after the group’s September 2023 ransomware attacks disrupted operations at Las Vegas casinos operated by MGM Resorts and Caesars Entertainment.

The story also noted that Jubair’s alleged handles on cybercrime-focused Telegram channels had far lengthier rap sheets involving some of the more consequential and headline-grabbing data breaches over the past four years. What follows is an account of cybercrime activities that prosecutors have attributed to Jubair’s alleged hacker handles, as told by those accounts in posts to public Telegram channels that are closely monitored by multiple cyber intelligence firms.

EARLY DAYS (2021-2022)

Jubair is alleged to have been a core member of the LAPSUS$ cybercrime group that broke into dozens of technology companies beginning in late 2021, stealing source code and other internal data from tech giants including Microsoft, Nvidia, Okta, Rockstar Games, Samsung, T-Mobile, and Uber.

That is, according to the former leader of the now-defunct LAPSUS$. In April 2022, KrebsOnSecurity published internal chat records taken from a server that LAPSUS$ used, and those chats indicate Jubair was working with the group using the nicknames Amtrak and Asyntax. In the middle of the gang’s cybercrime spree, Asyntax told the LAPSUS$ leader not to share T-Mobile’s logo in images sent to the group because he’d been previously busted for SIM-swapping and his parents would suspect he was back at it again.

The leader of LAPSUS$ responded by gleefully posting Asyntax’s real name, phone number, and other hacker handles into a public chat room on Telegram:

That story about the leaked LAPSUS$ chats also connected Amtrak/Asyntax to several previous hacker identities, including “Everlynn,” who in April 2021 began offering a cybercriminal service that sold fraudulent “emergency data requests” targeting the major social media and email providers.

In these so-called “fake EDR” schemes, the hackers compromise email accounts tied to police departments and government agencies, and then send unauthorized demands for subscriber data (e.g. username, IP/email address), while claiming the information being requested can’t wait for a court order because it relates to an urgent matter of life and death.

EARTHTOSTAR

Prosecutors in New Jersey last week alleged Jubair was part of a threat group variously known as Scattered Spider, 0ktapus, and UNC3944, and that he used the nicknames EarthtoStar, Brad, Austin, and Austistic.

Beginning in 2022, EarthtoStar co-ran a bustling Telegram channel called Star Chat, which was home to a prolific SIM-swapping group that relentlessly used voice- and SMS-based phishing attacks to steal credentials from employees at the major wireless providers in the U.S. and U.K.

The group would then use that access to sell a SIM-swapping service that could redirect a target’s phone number to a device the attackers controlled, allowing them to intercept the victim’s phone calls and text messages (including one-time codes). Members of Star Chat targeted multiple wireless carriers with SIM-swapping attacks, but they focused mainly on phishing T-Mobile employees.

In February 2023, KrebsOnSecurity scrutinized more than seven months of these SIM-swapping solicitations on Star Chat, which almost daily peppered the public channel with “Tmo up!” and “Tmo down!” notices indicating periods wherein the group claimed to have active access to T-Mobile’s network.

The data showed that Star Chat — along with two other SIM-swapping groups operating at the same time — collectively broke into T-Mobile over a hundred times in the last seven months of 2022. However, Star Chat was by far the most prolific of the three, responsible for at least 70 of those incidents.

A review of EarthtoStar’s messages on Star Chat as indexed by the threat intelligence firm Flashpoint shows this person also sold “AT&T email resets” and AT&T call forwarding services for up to $1,200 per line. EarthtoStar explained the purpose of this service in post on Telegram:

“Ok people are confused, so you know when u login to chase and it says ‘2fa required’ or whatever the fuck, well it gives you two options, SMS or Call. If you press call, and I forward the line to you then who do you think will get said call?”

New Jersey prosecutors allege Jubair also was involved in a mass SMS phishing campaign during the summer of 2022 that stole single sign-on credentials from employees at hundreds of companies. The text messages asked users to click a link and log in at a phishing page that mimicked their employer’s Okta authentication page, saying recipients needed to review pending changes to their upcoming work schedules.

The phishing websites used a Telegram instant message bot to forward any submitted credentials in real-time, allowing the attackers to use the phished username, password and one-time code to log in as that employee at the real employer website.

That weeks-long SMS phishing campaign led to intrusions and data thefts at more than 130 organizations, including LastPass, DoorDash, Mailchimp, Plex and Signal.

DA, COMRADE

EarthtoStar’s group Star Chat specialized in phishing their way into business process outsourcing (BPO) companies that provide customer support for a range of multinational companies, including a number of the world’s largest telecommunications providers. In May 2022, EarthtoStar posted to the Telegram channel “Frauwudchat”:

“Hi, I am looking for partners in order to exfiltrate data from large telecommunications companies/call centers/alike, I have major experience in this field, [including] a massive call center which houses 200,000+ employees where I have dumped all user credentials and gained access to the [domain controller] + obtained global administrator I also have experience with REST API’s and programming. I have extensive experience with VPN, Citrix, cisco anyconnect, social engineering + privilege escalation. If you have any Citrix/Cisco VPN or any other useful things please message me and lets work.”

At around the same time in the Summer of 2022, at least two different accounts tied to Star Chat — “RocketAce” and “Lopiu” — introduced the group’s services to denizens of the Russian-language cybercrime forum Exploit, including:

-SIM-swapping services targeting Verizon and T-Mobile customers;
-Dynamic phishing pages targeting customers of single sign-on providers like Okta;
-Malware development services;
-The sale of extended validation (EV) code signing certificates.

These two accounts on Exploit created multiple sales threads in which they claimed administrative access to U.S. telecommunications providers and asked other Exploit members for help in monetizing that access. In June 2022, RocketAce, which appears to have been just one of EarthtoStar’s many aliases, posted to Exploit:

Hello. I have access to a telecommunications company’s citrix and vpn. I would like someone to help me break out of the system and potentially attack the domain controller so all logins can be extracted we can discuss payment and things leave your telegram in the comments or private message me ! Looking for someone with knowledge in citrix/privilege escalation

On Nov. 15, 2022, EarthtoStar posted to their Star Sanctuary Telegram channel that they were hiring malware developers with a minimum of three years of experience and the ability to develop rootkits, backdoors and malware loaders.

“Optional: Endorsed by advanced APT Groups (e.g. Conti, Ryuk),” the ad concluded, referencing two of Russia’s most rapacious and destructive ransomware affiliate operations. “Part of a nation-state / ex-3l (3 letter-agency).”

2023-PRESENT DAY

The Telegram and Discord chat channels wherein Flowers and Jubair allegedly planned and executed their extortion attacks are part of a loose-knit network known as the Com, an English-speaking cybercrime community consisting mostly of individuals living in the United States, the United Kingdom, Canada and Australia.

Many of these Com chat servers have hundreds to thousands of members each, and some of the more interesting solicitations on these communities are job offers for in-person assignments and tasks that can be found if one searches for posts titled, “If you live near,” or “IRL job” — short for “in real life” job.

These “violence-as-a-service” solicitations typically involve “brickings,” where someone is hired to toss a brick through the window at a specified address. Other IRL jobs for hire include tire-stabbings, molotov cocktail hurlings, drive-by shootings, and even home invasions. The people targeted by these services are typically other criminals within the community, but it’s not unusual to see Com members asking others for help in harassing or intimidating security researchers and even the very law enforcement officers who are investigating their alleged crimes.

It remains unclear what precipitated this incident or what followed directly after, but on January 13, 2023, a Star Sanctuary account used by EarthtoStar solicited the home invasion of a sitting U.S. federal prosecutor from New York. That post included a photo of the prosecutor taken from the Justice Department’s website, along with the message:

“Need irl niggas, in home hostage shit no fucking pussies no skinny glock holding 100 pound niggas either”

Throughout late 2022 and early 2023, EarthtoStar’s alias “Brad” (a.k.a. “Brad_banned”) frequently advertised Star Chat’s malware development services, including custom malicious software designed to hide the attacker’s presence on a victim machine:

We can develop KERNEL malware which will achieve persistence for a long time,
bypass firewalls and have reverse shell access.

This shit is literally like STAGE 4 CANCER FOR COMPUTERS!!!

Kernel meaning the highest level of authority on a machine.
This can range to simple shells to Bootkits.

Bypass all major EDR’s (SentinelOne, CrowdStrike, etc)
Patch EDR’s scanning functionality so it’s rendered useless!

Once implanted, extremely difficult to remove (basically impossible to even find)
Development Experience of several years and in multiple APT Groups.

Be one step ahead of the game. Prices start from $5,000+. Message @brad_banned to get a quote

In September 2023 , both MGM Resorts and Caesars Entertainment suffered ransomware attacks at the hands of a Russian ransomware affiliate program known as ALPHV and BlackCat. Caesars reportedly paid a $15 million ransom in that incident.

Within hours of MGM publicly acknowledging the 2023 breach, members of Scattered Spider were claiming credit and telling reporters they’d broken in by social engineering a third-party IT vendor. At a hearing in London last week, U.K. prosecutors told the court Jubair was found in possession of more than $50 million in ill-gotten cryptocurrency, including funds that were linked to the Las Vegas casino hacks.

The Star Chat channel was finally banned by Telegram on March 9, 2025. But U.S. prosecutors say Jubair and fellow Scattered Spider members continued their hacking, phishing and extortion activities up until September 2025.

In April 2025, the Com was buzzing about the publication of “The Com Cast,” a lengthy screed detailing Jubair’s alleged cybercriminal activities and nicknames over the years. This account included photos and voice recordings allegedly of Jubair, and asserted that in his early days on the Com Jubair used the nicknames Clark and Miku (these are both aliases used by Everlynn in connection with their fake EDR services).

More recently, the anonymous Com Cast author(s) claimed, Jubair had used the nickname “Operator,” which corresponds to a Com member who ran an automated Telegram-based doxing service that pulled consumer records from hacked data broker accounts. That public outing came after Operator allegedly seized control over the Doxbin, a long-running and highly toxic community that is used to “dox” or post deeply personal information on people.

“Operator/Clark/Miku: A key member of the ransomware group Scattered Spider, which consists of a diverse mix of individuals involved in SIM swapping and phishing,” the Com Cast account stated. “The group is an amalgamation of several key organizations, including Infinity Recursion (owned by Operator), True Alcorians (owned by earth2star), and Lapsus, which have come together to form a single collective.”

The New Jersey complaint (PDF) alleges Jubair and other Scattered Spider members committed computer fraud, wire fraud, and money laundering in relation to at least 120 computer network intrusions involving 47 U.S. entities between May 2022 and September 2025. The complaint alleges the group’s victims paid at least $115 million in ransom payments.

U.S. authorities say they traced some of those payments to Scattered Spider to an Internet server controlled by Jubair. The complaint states that a cryptocurrency wallet discovered on that server was used to purchase several gift cards, one of which was used at a food delivery company to send food to his apartment. Another gift card purchased with cryptocurrency from the same server was allegedly used to fund online gaming accounts under Jubair’s name. U.S. prosecutors said that when they seized that server they also seized $36 million in cryptocurrency.

The complaint also charges Jubair with involvement in a hacking incident in January 2025 against the U.S. courts system that targeted a U.S. magistrate judge overseeing a related Scattered Spider investigation. That other investigation appears to have been the prosecution of Noah Michael Urban, a 20-year-old Florida man charged in November 2024 by prosecutors in Los Angeles as one of five alleged Scattered Spider members.

Urban pleaded guilty in April 2025 to wire fraud and conspiracy charges, and in August he was sentenced to 10 years in federal prison. Speaking with KrebsOnSecurity from jail after his sentencing, Urban asserted that the judge gave him more time than prosecutors requested because he was mad that Scattered Spider hacked his email account.

A court transcript (PDF) from a status hearing in February 2025 shows Urban was telling the truth about the hacking incident that happened while he was in federal custody. The judge told attorneys for both sides that a co-defendant in the California case was trying to find out about Mr. Urban’s activity in the Florida case, and that the hacker accessed the account by impersonating a judge over the phone and requesting a password reset.

Allison Nixon is chief research officer at the New York based security firm Unit 221B, and easily one of the world’s leading experts on Com-based cybercrime activity. Nixon said the core problem with legally prosecuting well-known cybercriminals from the Com has traditionally been that the top offenders tend to be under the age of 18, and thus difficult to charge under federal hacking statutes.

In the United States, prosecutors typically wait until an underage cybercrime suspect becomes an adult to charge them. But until that day comes, she said, Com actors often feel emboldened to continue committing — and very often bragging about — serious cybercrime offenses.

“Here we have a special category of Com offenders that effectively enjoy legal immunity,” Nixon told KrebsOnSecurity. “Most get recruited to Com groups when they are older, but of those that join very young, such as 12 or 13, they seem to be the most dangerous because at that age they have no grounding in reality and so much longevity before they exit their legal immunity.”

Nixon said U.K. authorities face the same challenge when they briefly detain and search the homes of underage Com suspects: Namely, the teen suspects simply go right back to their respective cliques in the Com and start robbing and hurting people again the minute they’re released.

Indeed, the U.K. court heard from prosecutors last week that both Scattered Spider suspects were detained and/or searched by local law enforcement on multiple occasions, only to return to the Com less than 24 hours after being released each time.

“What we see is these young Com members become vectors for perpetrators to commit enormously harmful acts and even child abuse,” Nixon said. “The members of this special category of people who enjoy legal immunity are meeting up with foreign nationals and conducting these sometimes heinous acts at their behest.”

Nixon said many of these individuals have few friends in real life because they spend virtually all of their waking hours on Com channels, and so their entire sense of identity, community and self-worth gets wrapped up in their involvement with these online gangs. She said if the law was such that prosecutors could treat these people commensurate with the amount of harm they cause society, that would probably clear up a lot of this problem.

“If law enforcement was allowed to keep them in jail, they would quit reoffending,” she said.

The Times of London reports that Flowers is facing three charges under the Computer Misuse Act: two of conspiracy to commit an unauthorized act in relation to a computer causing/creating risk of serious damage to human welfare/national security and one of attempting to commit the same act. Maximum sentences for these offenses can range from 14 years to life in prison, depending on the impact of the crime.

Jubair is reportedly facing two charges in the U.K.: One of conspiracy to commit an unauthorized act in relation to a computer causing/creating risk of serious damage to human welfare/national security and one of failing to comply with a section 49 notice to disclose the key to protected information.

In the United States, Jubair is charged with computer fraud conspiracy, two counts of computer fraud, wire fraud conspiracy, two counts of wire fraud, and money laundering conspiracy. If extradited to the U.S., tried and convicted on all charges, he faces a maximum penalty of 95 years in prison.

In July 2025, the United Kingdom barred victims of hacking from paying ransoms to cybercriminal groups unless approved by officials. U.K. organizations that are considered part of critical infrastructure reportedly will face a complete ban, as will the entire public sector. U.K. victims of a hack are now required to notify officials to better inform policymakers on the scale of Britain’s ransomware problem.

For further reading (bless you), check out Bloomberg’s poignant story last week based on a year’s worth of jailhouse interviews with convicted Scattered Spider member Noah Urban.

In May 2025, the European Union levied financial sanctions on the owners of Stark Industries Solutions Ltd., a bulletproof hosting provider that materialized two weeks before Russia invaded Ukraine and quickly became a top source of Kremlin-linked cyberattacks and disinformation campaigns. But new findings show those sanctions have done little to stop Stark from simply rebranding and transferring their assets to other corporate entities controlled by its original hosting providers.

Materializing just two weeks before Russia invaded Ukraine in 2022, Stark Industries Solutions became a frequent source of massive DDoS attacks, Russian-language proxy and VPN services, malware tied to Russia-backed hacking groups, and fake news. ISPs like Stark are called “bulletproof” providers when they cultivate a reputation for ignoring any abuse complaints or police inquiries about activity on their networks.

In May 2025, the European Union sanctioned one of Stark’s two main conduits to the larger Internet — Moldova-based PQ Hosting — as well as the company’s Moldovan owners Yuri and Ivan Neculiti. The EU Commission said the Neculiti brothers and PQ Hosting were linked to Russia’s hybrid warfare efforts.

But a new report from Recorded Future finds that just prior to the sanctions being announced, Stark rebranded to the[.]hosting, under control of the Dutch entity WorkTitans BV (AS209847) on June 24, 2025. The Neculiti brothers reportedly got a heads up roughly 12 days before the sanctions were announced, when Moldovan and EU media reported on the forthcoming inclusion of the Neculiti brothers in the sanctions package.

In response, the Neculiti brothers moved much of Stark’s considerable address space and other resources over to a new company in Moldova called PQ Hosting Plus S.R.L., an entity reportedly connected to the Neculiti brothers thanks to the re-use of a phone number from the original PQ Hosting.

“Although the majority of associated infrastructure remains attributable to Stark Industries, these changes likely reflect an attempt to obfuscate ownership and sustain hosting services under new legal and network entities,” Recorded Future observed.

Neither the Recorded Future report nor the May 2025 sanctions from the EU mentioned a second critical pillar of Stark’s network that KrebsOnSecurity identified in a May 2024 profile on the notorious bulletproof hoster: The Netherlands-based hosting provider MIRhosting.

MIRhosting is operated by 38-year old Andrey Nesterenko, whose personal website says he is an accomplished concert pianist who began performing publicly at a young age. DomainTools says mirhosting[.]com is registered to Mr. Nesterenko and to Innovation IT Solutions Corp, which lists addresses in London and in Nesterenko’s stated hometown of Nizhny Novgorod, Russia.

According to the book Inside Cyber Warfare by Jeffrey Carr, Innovation IT Solutions Corp. was responsible for hosting StopGeorgia[.]ru, a hacktivist website for organizing cyberattacks against Georgia that appeared at the same time Russian forces invaded the former Soviet nation in 2008. That conflict was thought to be the first war ever fought in which a notable cyberattack and an actual military engagement happened simultaneously.

Mr. Nesterenko did not respond to requests for comment. In May 2024, Mr. Nesterenko said he couldn’t verify whether StopGeorgia was ever a customer because they didn’t keep records going back that far. But he maintained that Stark Industries Solutions was merely one client of many, and claimed MIRhosting had not received any actionable complaints about abuse on Stark.

However, it appears that MIRhosting is once again the new home of Stark Industries, and that MIRhosting employees are managing both the[.]hosting and WorkTitans — the primary beneficiaries of Stark’s assets.

A copy of the incorporation documents for WorkTitans BV obtained from the Dutch Chamber of Commerce shows WorkTitans also does business under the names Misfits Media and and WT Hosting (considering Stark’s historical connection to Russian disinformation websites, “Misfits Media” is a bit on the nose).

The incorporation document says the company was formed in 2019 by a y.zinad@worktitans.nl. That email address corresponds to a LinkedIn account for a Youssef Zinad, who says their personal websites are worktitans[.]nl and custom-solution[.]nl. The profile also links to a website (etripleasims dot nl) that LinkedIn currently blocks as malicious. All of these websites are or were hosted at MIRhosting.

Although Mr. Zinad’s LinkedIn profile does not mention any employment at MIRhosting, virtually all of his LinkedIn posts over the past year have been reposts of advertisements for MIRhosting’s services.

A Google search for Youssef Zinad reveals multiple startup-tracking websites that list him as the founder of the[.]hosting, which censys.io finds is hosted by PQ Hosting Plus S.R.L.

The Dutch Chamber of Commerce document says WorkTitans’ sole shareholder is a company in Almere, Netherlands called Fezzy B.V. Who runs Fezzy? The phone number listed in a Google search for Fezzy B.V. — 31651079755 — also was used to register a Facebook profile for a Youssef Zinad from the same town, according to the breach tracking service Constella Intelligence.

In a series of email exchanges leading up to KrebsOnSecurity’s May 2024 deep dive on Stark, Mr. Nesterenko included Mr. Zinad in the message thread (youssef@mirhosting.com), referring to him as part of the company’s legal team. The Dutch website stagemarkt[.]nl lists Youssef Zinad as an official contact for MIRhosting’s offices in Almere. Mr. Zinad did not respond to requests for comment.

Given the above, it is difficult to argue with the Recorded Future report on Stark’s rebranding, which concluded that “the EU’s sanctioning of Stark Industries was largely ineffective, as affiliated infrastructure remained operational and services were rapidly re-established under new branding, with no significant or lasting disruption.”

A 20-year-old Florida man at the center of a prolific cybercrime group known as “Scattered Spider” was sentenced to 10 years in federal prison today, and ordered to pay roughly $13 million in restitution to victims.

Noah Michael Urban of Palm Coast, Fla. pleaded guilty in April 2025 to charges of wire fraud and conspiracy. Florida prosecutors alleged Urban conspired with others to steal at least $800,000 from five victims via SIM-swapping attacks that diverted their mobile phone calls and text messages to devices controlled by Urban and his co-conspirators.

Although prosecutors had asked for Urban to serve eight years, Jacksonville news outlet News4Jax.com reports the federal judge in the case today opted to sentence Urban to 120 months in federal prison, ordering him to pay $13 million in restitution and undergo three years of supervised release after his sentence is completed.

In November 2024 Urban was charged by federal prosecutors in Los Angeles as one of five members of Scattered Spider (a.k.a. “Oktapus,” “Scatter Swine” and “UNC3944”), which specialized in SMS and voice phishing attacks that tricked employees at victim companies into entering their credentials and one-time passcodes at phishing websites. Urban pleaded guilty to one count of conspiracy to commit wire fraud in the California case, and the $13 million in restitution is intended to cover victims from both cases.

The targeted SMS scams spanned several months during the summer of 2022, asking employees to click a link and log in at a website that mimicked their employer’s Okta authentication page. Some SMS phishing messages told employees their VPN credentials were expiring and needed to be changed; other missives advised employees about changes to their upcoming work schedule.

That phishing spree netted Urban and others access to more than 130 companies, including Twilio, LastPass, DoorDash, MailChimp, and Plex. The government says the group used that access to steal proprietary company data and customer information, and that members also phished people to steal millions of dollars worth of cryptocurrency.

For many years, Urban’s online hacker aliases “King Bob” and “Sosa” were fixtures of the Com, a mostly Telegram and Discord-based community of English-speaking cybercriminals wherein hackers boast loudly about high-profile exploits and hacks that almost invariably begin with social engineering. King Bob constantly bragged on the Com about stealing unreleased rap music recordings from popular artists, presumably through SIM-swapping attacks. Many of those purloined tracks or “grails” he later sold or gave away on forums.

Sosa also was active in a particularly destructive group of accomplished criminal SIM-swappers known as “Star Fraud.” Cyberscoop’s AJ Vicens reported in 2023 that individuals within Star Fraud were likely involved in the high-profile Caesars Entertainment and MGM Resorts extortion attacks that same year.

The Star Fraud SIM-swapping group gained the ability to temporarily move targeted mobile numbers to devices they controlled by constantly phishing employees of the major mobile providers. In February 2023, KrebsOnSecurity published data taken from the Telegram channels for Star Fraud and two other SIM-swapping groups showing these crooks focused on SIM-swapping T-Mobile customers, and that they collectively claimed internal access to T-Mobile on 100 separate occasions over a 7-month period in 2022.

Reached via one of his King Bob accounts on Twitter/X, Urban called the sentence unjust, and said the judge in his case discounted his age as a factor.

“The judge purposefully ignored my age as a factor because of the fact another Scattered Spider member hacked him personally during the course of my case,” Urban said in reply to questions, noting that he was sending the messages from a Florida county jail. “He should have been removed as a judge much earlier on. But staying in county jail is torture.”

A court transcript (PDF) from a status hearing in February 2025 shows Urban was telling the truth about the hacking incident that happened while he was in federal custody. It involved an intrusion into a magistrate judge’s email account, where a copy of Urban’s sealed indictment was stolen. The judge told attorneys for both sides that a co-defendant in the California case was trying to find out about Mr. Urban’s activity in the Florida case.

“What it ultimately turned into a was a big faux pas,” Judge Harvey E. Schlesinger said. “The Court’s password…business is handled by an outside contractor. And somebody called the outside contractor representing Judge Toomey saying, ‘I need a password change.’ And they gave out the password change. That’s how whoever was making the phone call got into the court.”

A 22-year-old Oregon man has been arrested on suspicion of operating “Rapper Bot,” a massive botnet used to power a service for launching distributed denial-of-service (DDoS) attacks against targets — including a March 2025 DDoS that knocked Twitter/X offline. The Justice Department asserts the suspect and an unidentified co-conspirator rented out the botnet to online extortionists, and tried to stay off the radar of law enforcement by ensuring that their botnet was never pointed at KrebsOnSecurity.

On August 6, 2025, federal agents arrested Ethan J. Foltz of Springfield, Ore. on suspicion of operating Rapper Bot, a globally dispersed collection of tens of thousands of hacked Internet of Things (IoT) devices.

The complaint against Foltz explains the attacks usually clocked in at more than two terabits of junk data per second (a terabit is one trillion bits of data), which is more than enough traffic to cause serious problems for all but the most well-defended targets. The government says Rapper Bot consistently launched attacks that were “hundreds of times larger than the expected capacity of a typical server located in a data center,” and that some of its biggest attacks exceeded six terabits per second.

Indeed, Rapper Bot was reportedly responsible for the March 10, 2025 attack that caused intermittent outages on Twitter/X. The government says Rapper Bot’s most lucrative and frequent customers were involved in extorting online businesses — including numerous gambling operations based in China.

The criminal complaint was written by Elliott Peterson, an investigator with the Defense Criminal Investigative Service (DCIS), the criminal investigative division of the Department of Defense (DoD) Office of Inspector General. The complaint notes the DCIS got involved because several Internet addresses maintained by the DoD were the target of Rapper Bot attacks.

Peterson said he tracked Rapper Bot to Foltz after a subpoena to an ISP in Arizona that was hosting one of the botnet’s control servers showed the account was paid for via PayPal. More legal process to PayPal revealed Foltz’s Gmail account and previously used IP addresses. A subpoena to Google showed the defendant searched security blogs constantly for news about Rapper Bot, and for updates about competing DDoS-for-hire botnets.

According to the complaint, after having a search warrant served on his residence the defendant admitted to building and operating Rapper Bot, sharing the profits 50/50 with a person he claimed to know only by the hacker handle “Slaykings.” Foltz also shared with investigators the logs from his Telegram chats, wherein Foltz and Slaykings discussed how best to stay off the radar of law enforcement investigators while their competitors were getting busted.

Specifically, the two hackers chatted about a May 20 attack against KrebsOnSecurity.com that clocked in at more than 6.3 terabits of data per second. The brief attack was notable because at the time it was the largest DDoS that Google had ever mitigated (KrebsOnSecurity sits behind the protection of Project Shield, a free DDoS defense service that Google provides to websites offering news, human rights, and election-related content).

The May 2025 DDoS was launched by an IoT botnet called Aisuru, which I discovered was operated by a 21-year-old man in Brazil named Kaike Southier Leite. This individual was more commonly known online as “Forky,” and Forky told me he wasn’t afraid of me or U.S. federal investigators. Nevertheless, the complaint against Foltz notes that Forky’s botnet seemed to diminish in size and firepower at the same time that Rapper Bot’s infection numbers were on the upswing.

“Both FOLTZ and Slaykings were very dismissive of attention seeking activities, the most extreme of which, in their view, was to launch DDoS attacks against the website of the prominent cyber security journalist Brian Krebs,” Peterson wrote in the criminal complaint.

“You see, they’ll get themselves [expletive],” Slaykings wrote in response to Foltz’s comments about Forky and Aisuru bringing too much heat on themselves.

“Prob cuz [redacted] hit krebs,” Foltz wrote in reply.

“Going against Krebs isn’t a good move,” Slaykings concurred. “It isn’t about being a [expletive] or afraid, you just get a lot of problems for zero money. Childish, but good. Let them die.”

“Ye, it’s good tho, they will die,” Foltz replied.

The government states that just prior to Foltz’s arrest, Rapper Bot had enslaved an estimated 65,000 devices globally. That may sound like a lot, but the complaint notes the defendants weren’t interested in making headlines for building the world’s largest or most powerful botnet.

Quite the contrary: The complaint asserts that the accused took care to maintain their botnet in a “Goldilocks” size — ensuring that “the number of devices afforded powerful attacks while still being manageable to control and, in the hopes of Foltz and his partners, small enough to not be detected.”

The complaint states that several days later, Foltz and Slaykings returned to discussing what that they expected to befall their rival group, with Slaykings stating, “Krebs is very revenge. He won’t stop until they are [expletive] to the bone.”

“Surprised they have any bots left,” Foltz answered.

“Krebs is not the one you want to have on your back. Not because he is scary or something, just because he will not give up UNTIL you are [expletive] [expletive]. Proved it with Mirai and many other cases.”

[Unknown expletives aside, that may well be the highest compliment I’ve ever been paid by a cybercriminal. I might even have part of that quote made into a t-shirt or mug or something. It’s also nice that they didn’t let any of their customers attack my site — if even only out of a paranoid sense of self-preservation.]

Foltz admitted to wiping the user and attack logs for the botnet approximately once a week, so investigators were unable to tally the total number of attacks, customers and targets of this vast crime machine. But the data that was still available showed that from April 2025 to early August, Rapper Bot conducted over 370,000 attacks, targeting 18,000 unique victims across 1,000 networks, with the bulk of victims residing in China, Japan, the United States, Ireland and Hong Kong (in that order).

According to the government, Rapper Bot borrows much of its code from fBot, a DDoS malware strain also known as Satori. In 2020, authorities in Northern Ireland charged a then 20-year-old man named Aaron “Vamp” Sterritt with operating fBot with a co-conspirator. U.S. prosecutors are still seeking Sterritt’s extradition to the United States. fBot is itself a variation of the Mirai IoT botnet that has ravaged the Internet with DDoS attacks since its source code was leaked back in 2016.

The complaint says Foltz and his partner did not allow most customers to launch attacks that were more than 60 seconds in duration — another way they tried to keep public attention to the botnet at a minimum. However, the government says the proprietors also had special arrangements with certain high-paying clients that allowed much larger and longer attacks.

Most people who have never been on the receiving end of a monster DDoS attack have no idea of the cost and disruption that such sieges can bring. The DCIS’s Peterson wrote that he was able to test the botnet’s capabilities while interviewing Foltz, and that found that “if this had been a server upon which I was running a website, using services such as load balancers, and paying for both outgoing and incoming data, at estimated industry average rates the attack (2+ Terabits per second times 30 seconds) might have cost the victim anywhere from $500 to $10,000.”

“DDoS attacks at this scale often expose victims to devastating financial impact, and a potential alternative, network engineering solutions that mitigate the expected attacks such as overprovisioning, i.e. increasing potential Internet capacity, or DDoS defense technologies, can themselves be prohibitively expensive,” the complaint continues. “This ‘rock and a hard place’ reality for many victims can leave them acutely exposed to extortion demands – ‘pay X dollars and the DDoS attacks stop’.”

The Telegram chat records show that the day before Peterson and other federal agents raided Foltz’s residence, Foltz allegedly told his partner he’d found 32,000 new devices that were vulnerable to a previously unknown exploit.

Shortly before the search warrant was served on his residence, Foltz allegedly told his partner that “Once again we have the biggest botnet in the community.” The following day, Foltz told his partner that it was going to be a great day — the biggest so far in terms of income generated by Rapper Bot.

“I sat next to Foltz while the messages poured in — promises of $800, then $1,000, the proceeds ticking up as the day went on,” Peterson wrote. “Noticing a change in Foltz’ behavior and concerned that Foltz was making changes to the botnet configuration in real time, Slaykings asked him ‘What’s up?’ Foltz deftly typed out some quick responses. Reassured by Foltz’ answer, Slaykings responded, ‘Ok, I’m the paranoid one.”

The case is being prosecuted by Assistant U.S. Attorney Adam Alexander in the District of Alaska (at least some of the devices found to be infected with Rapper Bot were located there, and it is where Peterson is stationed). Foltz faces one count of aiding and abetting computer intrusions. If convicted, he faces a maximum penalty of 10 years in prison, although a federal judge is unlikely to award anywhere near that kind of sentence for a first-time conviction.

Cybercriminal groups peddling sophisticated phishing kits that convert stolen card data into mobile wallets have recently shifted their focus to targeting customers of brokerage services, new research shows. Undeterred by security controls at these trading platforms that block users from wiring funds directly out of accounts, the phishers have pivoted to using multiple compromised brokerage accounts in unison to manipulate the prices of foreign stocks.

This so-called ‘ramp and dump‘ scheme borrows its name from age-old “pump and dump” scams, wherein fraudsters purchase a large number of shares in some penny stock, and then promote the company in a frenzied social media blitz to build up interest from other investors. The fraudsters dump their shares after the price of the penny stock increases to some degree, which usually then causes a sharp drop in the value of the shares for legitimate investors.

With ramp and dump, the scammers do not need to rely on ginning up interest in the targeted stock on social media. Rather, they will preposition themselves in the stock that they wish to inflate, using compromised accounts to purchase large volumes of it and then dumping the shares after the stock price reaches a certain value. In February 2025, the FBI said it was seeking information from victims of this scheme.

“In this variation, the price manipulation is primarily the result of controlled trading activity conducted by the bad actors behind the scam,” reads an advisory from the Financial Industry Regulatory Authority (FINRA), a private, non-profit organization that regulates member brokerage firms. “Ultimately, the outcome for unsuspecting investors is the same—a catastrophic collapse in share price that leaves investors with unrecoverable losses.”

Ford Merrill is a security researcher at SecAlliance, a CSIS Security Group company. Merrill said he has tracked recent ramp-and-dump activity to a bustling Chinese-language community that is quite openly selling advanced mobile phishing kits on Telegram.

“They will often coordinate with other actors and will wait until a certain time to buy a particular Chinese IPO [initial public offering] stock or penny stock,” said Merrill, who has been chronicling the rapid maturation and growth of the China-based phishing community over the past three years.

“They’ll use all these victim brokerage accounts, and if needed they’ll liquidate the account’s current positions, and will preposition themselves in that instrument in some account they control, and then sell everything when the price goes up,” he said. “The victim will be left with worthless shares of that equity in their account, and the brokerage may not be happy either.”

Merrill said the early days of these phishing groups — between 2022 and 2024 — were typified by phishing kits that used text messages to spoof the U.S. Postal Service or some local toll road operator, warning about a delinquent shipping or toll fee that needed paying. Recipients who clicked the link and provided their payment information at a fake USPS or toll operator site were then asked to verify the transaction by sharing a one-time code sent via text message.

In reality, the victim’s bank is sending that code to the mobile number on file for their customer because the fraudsters have just attempted to enroll that victim’s card details into a mobile wallet. If the visitor supplies that one-time code, their payment card is then added to a new mobile wallet on an Apple or Google device that is physically controlled by the phishers.

The phishing gangs typically load multiple stolen cards to digital wallets on a single Apple or Android device, and then sell those phones in bulk to scammers who use them for fraudulent e-commerce and tap-to-pay transactions.

This China-based phishing collective exposed a major weakness common to many U.S.-based financial institutions that already require multi-factor authentication: The reliance on a single, phishable one-time token for provisioning mobile wallets. Happily, Merrill said many financial institutions that were caught flat-footed on this scam two years ago have since strengthened authentication requirements for onboarding new mobile wallets (such as requiring the card to be enrolled via the bank’s mobile app).

But just as squeezing one part of a balloon merely forces the air trapped inside to bulge into another area, fraudsters don’t go away when you make their current enterprise less profitable: They just shift their focus to a less-guarded area. And lately, that gaze has settled squarely on customers of the major brokerage platforms, Merrill said.

THE OUTSIDER

Merrill pointed to several Telegram channels operated by some of the more accomplished phishing kit sellers, which are full of videos demonstrating how every feature in their kits can be tailored to the attacker’s target. The video snippet below comes from the Telegram channel of “Outsider,” a popular Mandarin-speaking phishing kit vendor whose latest offering includes a number of ready-made templates for using text messages to phish brokerage account credentials and one-time codes.

According to Merrill, Outsider is a woman who previously went by the handle “Chenlun.” KrebsOnSecurity profiled Chenlun’s phishing empire in an October 2023 story about a China-based group that was phishing mobile customers of more than a dozen postal services around the globe. In that case, the phishing sites were using a Telegram bot that sent stolen credentials to the “@chenlun” Telegram account.

Chenlun’s phishing lures are sent via Apple’s iMessage and Google’s RCS service and spoof one of the major brokerage platforms, warning that the account has been suspended for suspicious activity and that recipients should log in and verify some information. The missives include a link to a phishing page that collects the customer’s username and password, and then asks the user to enter a one-time code that will arrive via SMS.

The new phish kit videos on Outsider’s Telegram channel only feature templates for Schwab customers, but Merrill said the kit can easily be adapted to target other brokerage platforms. One reason the fraudsters are picking on brokerage firms, he said, has to do with the way they handle multi-factor authentication.

Schwab clients are presented with two options for second factor authentication when they open an account. Users who select the option to only prompt for a code on untrusted devices can choose to receive it via text message, an automated inbound phone call, or an outbound call to Schwab. With the “always at login” option selected, users can choose to receive the code through the Schwab app, a text message, or a Symantec VIP mobile app.

In response to questions, Schwab said it regularly updates clients on emerging fraud trends, including this specific type, which the company addressed in communications sent to clients earlier this year.

“That message focused on trading-related fraud, highlighting both account intrusions and scams conducted through social media or messaging apps that deceive individuals into executing trades themselves,” Schwab said in a written statement. “We are aware and tracking this trend across several channels, as well as others like it, which attempt to exploit SMS-based verification with stolen credentials. We actively monitor for suspicious patterns and take steps to disrupt them. This activity is part of a broader, industry-wide threat, and we take a multi-layered approach to address and mitigate it.”

Other popular brokerage platforms allow similar methods for multi-factor authentication. Fidelity requires a username and password on initial login, and offers the ability to receive a one-time token via SMS, an automated phone call, or by approving a push notification sent through the Fidelity mobile app. However, all three of these methods for sending one-time tokens are phishable; even with the brokerage firm’s app, the phishers could prompt the user to approve a login request that they initiated in the app with the phished credentials.

Vanguard offers customers a range of multi-factor authentication choices, including the option to require a physical security key in addition to one’s credentials on each login. A security key implements a robust form of multi-factor authentication known as Universal 2nd Factor (U2F), which allows the user to complete the login process simply by connecting an enrolled USB or Bluetooth device and pressing a button. The key works without the need for any special software drivers, and the nice thing about it is your second factor cannot be phished.

THE PERFECT CRIME?

Merrill said that in many ways the ramp-and-dump scheme is the perfect crime because it leaves precious few connections between the victim brokerage accounts and the fraudsters.

“It’s really genius because it decouples so many things,” he said. “They can buy shares [in the stock to be pumped] in their personal account on the Chinese exchanges, and the price happens to go up. The Chinese or Hong Kong brokerages aren’t going to see anything funky.”

Merrill said it’s unclear exactly how those perpetrating these ramp-and-dump schemes coordinate their activities, such as whether the accounts are phished well in advance or shortly before being used to inflate the stock price of Chinese companies. The latter possibility would fit nicely with the existing human infrastructure these criminal groups already have in place.

For example, KrebsOnSecurity recently wrote about research from Merrill and other researchers showing the phishers behind these slick mobile phishing kits employed people to sit for hours at a time in front of large banks of mobile phones being used to send the text message lures. These technicians were needed to respond in real time to victims who were supplying the one-time code sent from their financial institution.

“You can get access to a victim’s brokerage with a one-time passcode, but then you sort of have to use it right away if you can’t set new security settings so you can come back to that account later,” Merrill said.

The rapid pace of innovations produced by these China-based phishing vendors is due in part to their use of artificial intelligence and large language models to help develop the mobile phishing kits, he added.

“These guys are vibe coding stuff together and using LLMs to translate things or help put the user interface together,” Merrill said. “It’s only a matter of time before they start to integrate the LLMs into their development cycle to make it more rapid. The technologies they are building definitely have helped lower the barrier of entry for everyone.”

A new documentary series about cybercrime airing next month on HBO Max features interviews with Yours Truly. The four-part series follows the exploits of Julius Kivimäki, a prolific Finnish hacker recently convicted of leaking tens of thousands of patient records from an online psychotherapy practice while attempting to extort the clinic and its patients.

The documentary, “Most Wanted: Teen Hacker,” explores the 27-year-old Kivimäki’s lengthy and increasingly destructive career, one that was marked by cyber attacks designed to result in real-world physical impacts on their targets.

By the age of 14, Kivimäki had fallen in with a group of criminal hackers who were mass-compromising websites and milking them for customer payment card data. Kivimäki and his friends enjoyed harassing and terrorizing others by “swatting” their homes — calling in fake hostage situations or bomb threats at a target’s address in the hopes of triggering a heavily-armed police response to that location.

On Dec. 26, 2014, Kivimäki and fellow members of a group of online hooligans calling themselves the Lizard Squad launched a massive distributed denial-of-service (DDoS) attack against the Sony Playstation and Microsoft Xbox Live platforms, preventing millions of users from playing with their shiny new gaming rigs the day after Christmas. The Lizard Squad later acknowledged that the stunt was planned to call attention to their new DDoS-for-hire service, which came online and started selling subscriptions shortly after the attack.

Finnish investigators said Kivimäki also was responsible for a 2014 bomb threat against former Sony Online Entertainment President John Smedley that grounded an American Airlines plane. That incident was widely reported to have started with a Twitter post from the Lizard Squad, after Smedley mentioned some upcoming travel plans online. But according to Smedley and Finnish investigators, the bomb threat started with a phone call from Kivimäki.

The creaky wheels of justice seemed to be catching up with Kivimäki in mid-2015, when a Finnish court found him guilty of more than 50,000 cybercrimes, including data breaches, payment fraud, and operating a global botnet of hacked computers. Unfortunately, the defendant was 17 at the time, and received little more than a slap on the wrist: A two-year suspended sentence and a small fine.

Kivimäki immediately bragged online about the lenient sentencing, posting on Twitter that he was an “untouchable hacker god.” I wrote a column in 2015 lamenting his laughable punishment because it was clear even then that this was a person who enjoyed watching other people suffer, and who seemed utterly incapable of remorse about any of it. It was also abundantly clear to everyone who investigated his crimes that he wasn’t going to quit unless someone made him stop.

In response to some of my early reporting that mentioned Kivimäki, one reader shared that they had been dealing with non-stop harassment and abuse from Kivimäki for years, including swatting incidents, unwanted deliveries and subscriptions, emails to her friends and co-workers, as well as threatening phonecalls and texts at all hours of the night. The reader, who spoke on condition of anonymity, shared that Kivimäki at one point confided that he had no reason whatsoever for harassing her — that she was picked at random and that it was just something he did for laughs.

Five years after Kivimäki’s conviction, the Vastaamo Psychotherapy Center in Finland became the target of blackmail when a tormentor identified as “ransom_man” demanded payment of 40 bitcoins (~450,000 euros at the time) in return for a promise not to publish highly sensitive therapy session notes Vastaamo had exposed online.

Ransom_man, a.k.a. Kivimäki, announced on the dark web that he would start publishing 100 patient profiles every 24 hours. When Vastaamo declined to pay, ransom_man shifted to extorting individual patients. According to Finnish police, some 22,000 victims reported extortion attempts targeting them personally, targeted emails that threatened to publish their therapy notes online unless paid a 500 euro ransom.

In October 2022, Finnish authorities charged Kivimäki with extorting Vastaamo and its patients. But by that time he was on the run from the law and living it up across Europe, spending lavishly on fancy cars, apartments and a hard-partying lifestyle.

In February 2023, Kivimäki was arrested in France after authorities there responded to a domestic disturbance call and found the defendant sleeping off a hangover on the couch of a woman he’d met the night before. The French police grew suspicious when the 6′ 3″ blonde, green-eyed man presented an ID that stated he was of Romanian nationality.

In April 2024, Kivimäki was sentenced to more than six years in prison after being convicted of extorting Vastaamo and its patients.

The documentary is directed by the award-winning Finnish producer and director Sami Kieski and co-written by Joni Soila. According to an August 6 press release, the four 43-minute episodes will drop weekly on Fridays throughout September across Europe, the U.S, Latin America, Australia and South-East Asia.

On July 22, 2025, the European police agency Europol said a long-running investigation led by the French Police resulted in the arrest of a 38-year-old administrator of XSS, a Russian-language cybercrime forum with more than 50,000 members. The action has triggered an ongoing frenzy of speculation and panic among XSS denizens about the identity of the unnamed suspect, but the consensus is that he is a pivotal figure in the crime forum scene who goes by the hacker handle “Toha.” Here’s a deep dive on what’s knowable about Toha, and a short stab at who got nabbed.

Europol did not name the accused, but published partially obscured photos of him from the raid on his residence in Kiev. The police agency said the suspect acted as a trusted third party — arbitrating disputes between criminals — and guaranteeing the security of transactions on XSS. A statement from Ukraine’s SBU security service said XSS counted among its members many cybercriminals from various ransomware groups, including REvil, LockBit, Conti, and Qiliin.

Since the Europol announcement, the XSS forum resurfaced at a new address on the deep web (reachable only via the anonymity network Tor). But from reviewing the recent posts, there appears to be little consensus among longtime members about the identity of the now-detained XSS administrator.

The most frequent comment regarding the arrest was a message of solidarity and support for Toha, the handle chosen by the longtime administrator of XSS and several other major Russian forums. Toha’s accounts on other forums have been silent since the raid.

Europol said the suspect has enjoyed a nearly 20-year career in cybercrime, which roughly lines up with Toha’s history. In 2005, Toha was a founding member of the Russian-speaking forum Hack-All. That is, until it got massively hacked a few months after its debut. In 2006, Toha rebranded the forum to exploit[.]in, which would go on to draw tens of thousands of members, including an eventual Who’s-Who of wanted cybercriminals.

Toha announced in 2018 that he was selling the Exploit forum, prompting rampant speculation on the forums that the buyer was secretly a Russian or Ukrainian government entity or front person. However, those suspicions were unsupported by evidence, and Toha vehemently denied the forum had been given over to authorities.

One of the oldest Russian-language cybercrime forums was DaMaGeLaB, which operated from 2004 to 2017, when its administrator “Ar3s” was arrested. In 2018, a partial backup of the DaMaGeLaB forum was reincarnated as xss[.]is, with Toha as its stated administrator.

CROSS-SITE GRIFTING

Clues about Toha’s early presence on the Internet — from ~2004 to 2010 — are available in the archives of Intel 471, a cyber intelligence firm that tracks forum activity. Intel 471 shows Toha used the same email address across multiple forum accounts, including at Exploit, Antichat, Carder[.]su and inattack[.]ru.

DomainTools.com finds Toha’s email address — toschka2003@yandex.ru — was used to register at least a dozen domain names — most of them from the mid- to late 2000s. Apart from exploit[.]in and a domain called ixyq[.]com, the other domains registered to that email address end in .ua, the top-level domain for Ukraine (e.g. deleted.org[.]ua, lj.com[.]ua, and blogspot.org[.]ua).

Nearly all of the domains registered to toschka2003@yandex.ru contain the name Anton Medvedovskiy in the registration records, except for the aforementioned ixyq[.]com, which is registered to the name Yuriy Avdeev in Moscow.

This Avdeev surname came up in a lengthy conversation with Lockbitsupp, the leader of the rapacious and destructive ransomware affiliate group Lockbit. The conversation took place in February 2024, when Lockbitsupp asked for help identifying Toha’s real-life identity.

Lockbitsupp didn’t share why he wanted Toha’s details, but he maintained that Toha’s real name was Anton Avdeev. I declined to help Lockbitsupp in whatever revenge he was planning on Toha, but his question made me curious to look deeper.

It appears Lockbitsupp’s query was based on a now-deleted Twitter post from 2022, when a user by the name “3xp0rt” asserted that Toha was a Russian man named Anton Viktorovich Avdeev, born October 27, 1983.

Searching the web for Toha’s email address toschka2003@yandex.ru reveals a 2010 sales thread on the forum bmwclub.ru where a user named Honeypo was selling a 2007 BMW X5. The ad listed the contact person as Anton Avdeev and gave the contact phone number 9588693.

A search on the phone number 9588693 in the breach tracking service Constella Intelligence finds plenty of official Russian government records with this number, date of birth and the name Anton Viktorovich Avdeev. For example, hacked Russian government records show this person has a Russian tax ID and SIN (Social Security number), and that they were flagged for traffic violations on several occasions by Moscow police; in 2004, 2006, 2009, and 2014.

Astute readers may have noticed by now that the ages of Mr. Avdeev (41) and the XSS admin arrested this month (38) are a bit off. This would seem to suggest that the person arrested is someone other than Mr. Avdeev, who did not respond to requests for comment.

A FLY ON THE WALL

For further insight on this question, KrebsOnSecurity sought comments from Sergeii Vovnenko, a former cybercriminal from Ukraine who now works at the security startup paranoidlab.com. I reached out to Vovnenko because for several years beginning around 2010 he was the owner and operator of thesecure[.]biz, an encrypted “Jabber” instant messaging server that Europol said was operated by the suspect arrested in Kiev. Thesecure[.]biz grew quite popular among many of the top Russian-speaking cybercriminals because it scrupulously kept few records of its users’ activity, and its administrator was always a trusted member of the community.

The reason I know this historic tidbit is that in 2013, Vovnenko — using the hacker nicknames “Fly,” and “Flycracker” — hatched a plan to have a gram of heroin purchased off of the Silk Road darknet market and shipped to our home in Northern Virginia. The scheme was to spoof a call from one of our neighbors to the local police, saying this guy Krebs down the street was a druggie who was having narcotics delivered to his home.

I happened to be lurking on Flycracker’s private cybercrime forum when his heroin-framing plan was carried out, and called the police myself before the smack eventually arrived in the U.S. Mail. Vovnenko was later arrested for unrelated cybercrime activities, extradited to the United States, convicted, and deported after a 16-month stay in the U.S. prison system [on several occasions, he has expressed heartfelt apologies for the incident, and we have since buried the hatchet].

Vovnenko said he purchased a device for cloning credit cards from Toha in 2009, and that Toha shipped the item from Russia. Vovnenko explained that he (Flycracker) was the owner and operator of thesecure[.]biz from 2010 until his arrest in 2014.

Vovnenko believes thesecure[.]biz was stolen while he was in jail, either by Toha and/or an XSS administrator who went by the nicknames N0klos and Sonic.

“When I was in jail, [the] admin of xss.is stole that domain, or probably N0klos bought XSS from Toha or vice versa,” Vovnenko said of the Jabber domain. “Nobody from [the forums] spoke with me after my jailtime, so I can only guess what really happened.”

N0klos was the owner and administrator of an early Russian-language cybercrime forum known as Darklife[.]ws. However, N0kl0s also appears to be a lifelong Russian resident, and in any case seems to have vanished from Russian cybercrime forums several years ago.

Asked whether he believes Toha was the XSS administrator who was arrested this month in Ukraine, Vovnenko maintained that Toha is Russian, and that “the French cops took the wrong guy.”

WHO IS TOHA?

So who did the Ukrainian police arrest in response to the investigation by the French authorities? It seems plausible that the BMW ad invoking Toha’s email address and the name and phone number of a Russian citizen was simply misdirection on Toha’s part — intended to confuse and throw off investigators. Perhaps this even explains the Avdeev surname surfacing in the registration records from one of Toha’s domains.

But sometimes the simplest answer is the correct one. “Toha” is a common Slavic nickname for someone with the first name “Anton,” and that matches the name in the registration records for more than a dozen domains tied to Toha’s toschka2003@yandex.ru email address: Anton Medvedovskiy.

Constella Intelligence finds there is an Anton Gannadievich Medvedovskiy living in Kiev who will be 38 years old in December. This individual owns the email address itsmail@i.ua, as well an an Airbnb account featuring a profile photo of a man with roughly the same hairline as the suspect in the blurred photos released by the Ukrainian police. Mr. Medvedovskiy did not respond to a request for comment.

My take on the takedown is that the Ukrainian authorities likely arrested Medvedovskiy. Toha shared on DaMaGeLab in 2005 that he had recently finished the 11th grade and was studying at a university — a time when Mevedovskiy would have been around 18 years old. On Dec. 11, 2006, fellow Exploit members wished Toha a happy birthday. Records exposed in a 2022 hack at the Ukrainian public services portal diia.gov.ua show that Mr. Medvedovskiy’s birthday is Dec. 11, 1987.

The law enforcement action and resulting confusion about the identity of the detained has thrown the Russian cybercrime forum scene into disarray in recent weeks, with lengthy and heated arguments about XSS’s future spooling out across the forums.

XSS relaunched on a new Tor address shortly after the authorities plastered their seizure notice on the forum’s  homepage, but all of the trusted moderators from the old forum were dismissed without explanation. Existing members saw their forum account balances drop to zero, and were asked to plunk down a deposit to register at the new forum. The new XSS “admin” said they were in contact with the previous owners and that the changes were to help rebuild security and trust within the community.

However, the new admin’s assurances appear to have done little to assuage the worst fears of the forum’s erstwhile members, most of whom seem to be keeping their distance from the relaunched site for now.

Indeed, if there is one common understanding amid all of these discussions about the seizure of XSS, it is that Ukrainian and French authorities now have several years worth of private messages between XSS forum users, as well as contact rosters and other user data linked to the seized Jabber server.

“The myth of the ‘trusted person’ is shattered,” the user “GordonBellford” cautioned on Aug. 3 in an Exploit forum thread about the XSS admin arrest. “The forum is run by strangers. They got everything. Two years of Jabber server logs. Full backup and forum database.”

GordonBellford continued:

And the scariest thing is: this data array is not just an archive. It is material for analysis that has ALREADY BEEN DONE . With the help of modern tools, they see everything:

Graphs of your contacts and activity.
Relationships between nicknames, emails, password hashes and Jabber ID.
Timestamps, IP addresses and digital fingerprints.
Your unique writing style, phraseology, punctuation, consistency of grammatical errors, and even typical typos that will link your accounts on different platforms.

They are not looking for a needle in a haystack. They simply sifted the haystack through the AI sieve and got ready-made dossiers.

KrebsOnSecurity recently heard from a reader whose boss’s email account got phished and was used to trick one of the company’s customers into sending a large payment to scammers. An investigation into the attacker’s infrastructure points to a long-running Nigerian cybercrime ring that is actively targeting established companies in the transportation and aviation industries.

A reader who works in the transportation industry sent a tip about a recent successful phishing campaign that tricked an executive at the company into entering their credentials at a fake Microsoft 365 login page. From there, the attackers quickly mined the executive’s inbox for past communications about invoices, copying and modifying some of those messages with new invoice demands that were sent to some of the company’s customers and partners.

Speaking on condition of anonymity, the reader said the resulting phishing emails to customers came from a newly registered domain name that was remarkably similar to their employer’s domain, and that at least one of their customers fell for the ruse and paid a phony invoice. They said the attackers had spun up a look-alike domain just a few hours after the executive’s inbox credentials were phished, and that the scam resulted in a customer suffering a six-figure financial loss.

The reader also shared that the email addresses in the registration records for the imposter domain — roomservice801@gmail.com — is tied to many such phishing domains. Indeed, a search on this email address at DomainTools.com finds it is associated with at least 240 domains registered in 2024 or 2025. Virtually all of them mimic legitimate domains for companies in the aerospace and transportation industries worldwide.

An Internet search for this email address reveals a humorous blog post from 2020 on the Russian forum hackware[.]ru, which found roomservice801@gmail.com was tied to a phishing attack that used the lure of phony invoices to trick the recipient into logging in at a fake Microsoft login page. We’ll come back to this research in a moment.

JUSTY JOHN

DomainTools shows that some of the early domains registered to roomservice801@gmail.com in 2016 include other useful information. For example, the WHOIS records for alhhomaidhicentre[.]biz reference the technical contact of “Justy John” and the email address justyjohn50@yahoo.com.

A search at DomainTools found justyjohn50@yahoo.com has been registering one-off phishing domains since at least 2012. At this point, I was convinced that some security company surely had already published an analysis of this particular threat group, but I didn’t yet have enough information to draw any solid conclusions.

DomainTools says the Justy John email address is tied to more than two dozen domains registered since 2012, but we can find hundreds more phishing domains and related email addresses simply by pivoting on details in the registration records for these Justy John domains. For example, the street address used by the Justy John domain axisupdate[.]net — 7902 Pelleaux Road in Knoxville, TN — also appears in the registration records for accountauthenticate[.]com, acctlogin[.]biz, and loginaccount[.]biz, all of which at one point included the email address rsmith60646@gmail.com.

That Rsmith Gmail address is connected to the 2012 phishing domain alibala[.]biz (one character off of the Chinese e-commerce giant alibaba.com, with a different top-level domain of .biz). A search in DomainTools on the phone number in those domain records — 1.7736491613 — reveals even more phishing domains as well as the Nigerian phone number “2348062918302” and the email address michsmith59@gmail.com.

DomainTools shows michsmith59@gmail.com appears in the registration records for the domain seltrock[.]com, which was used in the phishing attack documented in the 2020 Russian blog post mentioned earlier. At this point, we are just two steps away from identifying the threat actor group.

The same Nigerian phone number shows up in dozens of domain registrations that reference the email address sebastinekelly69@gmail.com, including 26i3[.]net, costamere[.]com, danagruop[.]us, and dividrilling[.]com. A Web search on any of those domains finds they were indexed in an “indicator of compromise” list on GitHub maintained by Palo Alto Networks‘ Unit 42 research team.

SILVERTERRIER

According to Unit 42, the domains are the handiwork of a vast cybercrime group based in Nigeria that it dubbed “SilverTerrier” back in 2014. In an October 2021 report, Palo Alto said SilverTerrier excels at so-called “business e-mail compromise” or BEC scams, which target legitimate business email accounts through social engineering or computer intrusion activities. BEC criminals use that access to initiate or redirect the transfer of business funds for personal gain.

Palo Alto says SilverTerrier encompasses hundreds of BEC fraudsters, some of whom have been arrested in various international law enforcement operations by Interpol. In 2022, Interpol and the Nigeria Police Force arrested 11 alleged SilverTerrier members, including a prominent SilverTerrier leader who’d been flaunting his wealth on social media for years. Unfortunately, the lure of easy money, endemic poverty and corruption, and low barriers to entry for cybercrime in Nigeria conspire to provide a constant stream of new recruits.

BEC scams were the 7th most reported crime tracked by the FBI’s Internet Crime Complaint Center (IC3) in 2024, generating more than 21,000 complaints. However, BEC scams were the second most costly form of cybercrime reported to the feds last year, with nearly $2.8 billion in claimed losses. In its 2025 Fraud and Control Survey Report, the Association for Financial Professionals found 63 percent of organizations experienced a BEC last year.

Poking at some of the email addresses that spool out from this research reveals a number of Facebook accounts for people residing in Nigeria or in the United Arab Emirates, many of whom do not appear to have tried to mask their real-life identities. Palo Alto’s Unit 42 researchers reached a similar conclusion, noting that although a small subset of these crooks went to great lengths to conceal their identities, it was usually simple to learn their identities on social media accounts and the major messaging services.

Palo Alto said BEC actors have become far more organized over time, and that while it remains easy to find actors working as a group, the practice of using one phone number, email address or alias to register malicious infrastructure in support of multiple actors has made it far more time consuming (but not impossible) for cybersecurity and law enforcement organizations to sort out which actors committed specific crimes.

“We continue to find that SilverTerrier actors, regardless of geographical location, are often connected through only a few degrees of separation on social media platforms,” the researchers wrote.

FINANCIAL FRAUD KILL CHAIN

Palo Alto has published a useful list of recommendations that organizations can adopt to minimize the incidence and impact of BEC attacks. Many of those tips are prophylactic, such as conducting regular employee security training and reviewing network security policies.

But one recommendation — getting familiar with a process known as the “financial fraud kill chain” or FFKC — bears specific mention because it offers the single best hope for BEC victims who are seeking to claw back payments made to fraudsters, and yet far too many victims don’t know it exists until it is too late.

As explained in this FBI primer, the International Financial Fraud Kill Chain is a partnership between federal law enforcement and financial entities whose purpose is to freeze fraudulent funds wired by victims. According to the FBI, viable victim complaints filed with ic3.gov promptly after a fraudulent transfer (generally less than 72 hours) will be automatically triaged by the Financial Crimes Enforcement Network (FinCEN).

The FBI noted in its IC3 annual report (PDF) that the FFKC had a 66 percent success rate in 2024. Viable ic3.gov complaints involve losses of at least $50,000, and include all records from the victim or victim bank, as well as a completed FFKC form (provided by FinCEN) containing victim information, recipient information, bank names, account numbers, location, SWIFT, and any additional information.

Authorities in the United Kingdom this week arrested four people aged 17 to 20 in connection with recent data theft and extortion attacks against the retailers Marks & Spencer and Harrods, and the British food retailer Co-op Group. The breaches have been linked to a prolific but loosely-affiliated cybercrime group dubbed “Scattered Spider,” whose other recent victims include multiple airlines.

The U.K.’s National Crime Agency (NCA) declined verify the names of those arrested, saying only that they included two males aged 19, another aged 17, and 20-year-old female.

Scattered Spider is the name given to an English-speaking cybercrime group known for using social engineering tactics to break into companies and steal data for ransom, often impersonating employees or contractors to deceive IT help desks into granting access. The FBI warned last month that Scattered Spider had recently shifted to targeting companies in the retail and airline sectors.

KrebsOnSecurity has learned the identities of two of the suspects. Multiple sources close to the investigation said those arrested include Owen David Flowers, a U.K. man alleged to have been involved in the cyber intrusion and ransomware attack that shut down several MGM Casino properties in September 2023. Those same sources said the woman arrested is or recently was in a relationship with Flowers.

Sources told KrebsOnSecurity that Flowers, who allegedly went by the hacker handles “bo764,” “Holy,” and “Nazi,” was the group member who anonymously gave interviews to the media in the days after the MGM hack. His real name was omitted from a September 2024 story about the group because he was not yet charged in that incident.

The bigger fish arrested this week is 19-year-old Thalha Jubair, a U.K. man whose alleged exploits under various monikers have been well-documented in stories on this site. Jubair is believed to have used the nickname “Earth2Star,” which corresponds to a founding member of the cybercrime-focused Telegram channel “Star Fraud Chat.”

In 2023, KrebsOnSecurity published an investigation into the work of three different SIM-swapping groups that phished credentials from T-Mobile employees and used that access to offer a service whereby any T-Mobile phone number could be swapped to a new device. Star Chat was by far the most active and consequential of the three SIM-swapping groups, who collectively broke into T-Mobile’s network more than 100 times in the second half of 2022.

Sources tell KrebsOnSecurity that Jubair also was a core member of the LAPSUS$ cybercrime group that broke into dozens of technology companies in 2022, stealing source code and other internal data from tech giants including Microsoft, Nvidia, Okta, Rockstar Games, Samsung, T-Mobile, and Uber.

In April 2022, KrebsOnSecurity published internal chat records from LAPSUS$, and those chats indicated Jubair was using the nicknames Amtrak and Asyntax. At one point in the chats, Amtrak told the LAPSUS$ group leader not to share T-Mobile’s logo in images sent to the group because he’d been previously busted for SIM-swapping and his parents would suspect he was back at it again.

As shown in those chats, the leader of LAPSUS$ eventually decided to betray Amtrak by posting his real name, phone number, and other hacker handles into a public chat room on Telegram.

That story about the leaked LAPSUS$ chats connected Amtrak/Asyntax/Jubair to the identity “Everlynn,” the founder of a cybercriminal service that sold fraudulent “emergency data requests” targeting the major social media and email providers. In such schemes, the hackers compromise email accounts tied to police departments and government agencies, and then send unauthorized demands for subscriber data while claiming the information being requested can’t wait for a court order because it relates to an urgent matter of life and death.

Sources say Jubair also used the nickname “Operator,” and that until recently he was the administrator of the Doxbin, a long-running and highly toxic online community that is used to “dox” or post deeply personal information on people. In May 2024, several popular cybercrime channels on Telegram ridiculed Operator after it was revealed that he’d staged his own kidnapping in a botched plan to throw off law enforcement investigators.

In November 2024, U.S. authorities charged five men aged 20 to 25 in connection with the Scattered Spider group, which has long relied on recruiting minors to carry out its most risky activities. Indeed, many of the group’s core members were recruited from online gaming platforms like Roblox and Minecraft in their early teens, and have been perfecting their social engineering tactics for years.

“There is a clear pattern that some of the most depraved threat actors first joined cybercrime gangs at an exceptionally young age,” said Allison Nixon, chief research officer at the New York based security firm Unit 221B. “Cybercriminals arrested at 15 or younger need serious intervention and monitoring to prevent a years long massive escalation.”

In May 2025, the U.S. government sanctioned a Chinese national for operating a cloud provider linked to the majority of virtual currency investment scam websites reported to the FBI. But a new report finds the accused continues to operate a slew of established accounts at American tech companies — including Facebook, Github, PayPal and Twitter/X.

On May 29, the U.S. Department of the Treasury announced economic sanctions against Funnull Technology Inc., a Philippines-based company alleged to provide infrastructure for hundreds of thousands of websites involved in virtual currency investment scams known as “pig butchering.” In January 2025, KrebsOnSecurity detailed how Funnull was designed as a content delivery network that catered to foreign cybercriminals seeking to route their traffic through U.S.-based cloud providers.

The Treasury also sanctioned Funnull’s alleged operator, a 40-year-old Chinese national named Liu “Steve” Lizhi. The government says Funnull directly facilitated financial schemes resulting in more than $200 million in financial losses by Americans, and that the company’s operations were linked to the majority of pig butchering scams reported to the FBI.

It is generally illegal for U.S. companies or individuals to transact with people sanctioned by the Treasury. However, as Mr. Lizhi’s case makes clear, just because someone is sanctioned doesn’t necessarily mean big tech companies are going to suspend their online accounts.

The government says Lizhi was born November 13, 1984, and used the nicknames “XXL4” and “Nice Lizhi.” Nevertheless, Steve Liu’s 17-year-old account on LinkedIn (in the name “Liulizhi”) had hundreds of followers (Lizhi’s LinkedIn profile helpfully confirms his birthday) until quite recently: The account was deleted this morning, just hours after KrebsOnSecurity sought comment from LinkedIn.

In an emailed response, a LinkedIn spokesperson said the company’s “Prohibited countries policy” states that LinkedIn “does not sell, license, support or otherwise make available its Premium accounts or other paid products and services to individuals and companies sanctioned by the U.S. government.” LinkedIn declined to say whether the profile in question was a premium or free account.

Mr. Lizhi also maintains a working PayPal account under the name Liu Lizhi and username “@nicelizhi,” another nickname listed in the Treasury sanctions. A 15-year-old Twitter/X account named “Lizhi” that links to Mr. Lizhi’s personal domain remains active, although it has few followers and hasn’t posted in years.

These accounts and many others were flagged by the security firm Silent Push, which has been tracking Funnull’s operations for the past year and calling out U.S. cloud providers like Amazon and Microsoft for failing to more quickly sever ties with the company.

In a report released today, Silent Push found Lizhi still operates numerous Facebook accounts and groups, including a private Facebook account under the name Liu Lizhi. Another Facebook account clearly connected to Lizhi is a tourism page for Ganzhou, China called “EnjoyGanzhou” that was named in the Treasury Department sanctions.

“This guy is the technical administrator for the infrastructure that is hosting a majority of scams targeting people in the United States, and hundreds of millions have been lost based on the websites he’s been hosting,” said Zach Edwards, senior threat researcher at Silent Push. “It’s crazy that the vast majority of big tech companies haven’t done anything to cut ties with this guy.”

The FBI says it received nearly 150,000 complaints last year involving digital assets and $9.3 billion in losses — a 66 percent increase from the previous year. Investment scams were the top crypto-related crimes reported, with $5.8 billion in losses.

In a statement, a Meta spokesperson said the company continuously takes steps to meet its legal obligations, but that sanctions laws are complex and varied. They explained that sanctions are often targeted in nature and don’t always prohibit people from having a presence on its platform. Nevertheless, Meta confirmed it had removed the account, unpublished Pages, and removed Groups and events associated with the user for violating its policies.

Attempts to reach Mr. Lizhi via his primary email addresses at Hotmail and Gmail bounced as undeliverable. Likewise, his 14-year-old YouTube channel appears to have been taken down recently.

However, anyone interested in viewing or using Mr. Lizhi’s 146 computer code repositories will have no problem finding GitHub accounts for him, including one registered under the NiceLizhi and XXL4 nicknames mentioned in the Treasury sanctions.

Mr. Lizhi also operates a GitHub page for an open source e-commerce platform called NexaMerchant, which advertises itself as a payment gateway working with numerous American financial institutions. Interestingly, this profile’s “followers” page shows several other accounts that appear to be Mr. Lizhi’s. All of the account’s followers are tagged as “suspended,” even though that suspended message does not display when one visits those individual profiles.

In response to questions, GitHub said it has a process in place to identify when users and customers are Specially Designated Nationals or other denied or blocked parties, but that it locks those accounts instead of removing them. According to its policy, GitHub takes care that users and customers aren’t impacted beyond what is required by law.

“This includes keeping public repositories, including those for open source projects, available and accessible to support personal communications involving developers in sanctioned regions,” the policy states. “This also means GitHub will advocate for developers in sanctioned regions to enjoy greater access to the platform and full access to the global open source community.”

Edwards said it’s great that GitHub has a process for handling sanctioned accounts, but that the process doesn’t seem to communicate risk in a transparent way, noting that the only indicator on the locked accounts is the message, “This repository has been archived by the owner. It is not read-only.”

“It’s an odd message that doesn’t communicate, ‘This is a sanctioned entity, don’t fork this code or use it in a production environment’,” Edwards said.

Mark Rasch is a former federal cybercrime prosecutor who now serves as counsel for the New York City based security consulting firm Unit 221B. Rasch said when Treasury’s Office of Foreign Assets Control (OFAC) sanctions a person or entity, it then becomes illegal for businesses or organizations to transact with the sanctioned party.

Rasch said financial institutions have very mature systems for severing accounts tied to people who become subject to OFAC sanctions, but that tech companies may be far less proactive — particularly with free accounts.

“Banks have established ways of checking [U.S. government sanctions lists] for sanctioned entities, but tech companies don’t necessarily do a good job with that, especially for services that you can just click and sign up for,” Rasch said. “It’s potentially a risk and liability for the tech companies involved, but only to the extent OFAC is willing to enforce it.”

In July 2024, Funnull purchased the domain polyfill[.]io, the longtime home of a legitimate open source project that allowed websites to ensure that devices using legacy browsers could still render content in newer formats. After the Polyfill domain changed hands, at least 384,000 websites were caught in a supply-chain attack that redirected visitors to malicious sites. According to the Treasury, Funnull used the code to redirect people to scam websites and online gambling sites, some of which were linked to Chinese criminal money laundering operations.

The U.S. government says Funnull provides domain names for websites on its purchased IP addresses, using domain generation algorithms (DGAs) — programs that generate large numbers of similar but unique names for websites — and that it sells web design templates to cybercriminals.

“These services not only make it easier for cybercriminals to impersonate trusted brands when creating scam websites, but also allow them to quickly change to different domain names and IP addresses when legitimate providers attempt to take the websites down,” reads a Treasury statement.

Meanwhile, Funnull appears to be morphing nearly all aspects of its business in the wake of the sanctions, Edwards said.

“Whereas before they might have used 60 DGA domains to hide and bounce their traffic, we’re seeing far more now,” he said. “They’re trying to make their infrastructure harder to track and more complicated, so for now they’re not going away but more just changing what they’re doing. And a lot more organizations should be holding their feet to the fire.”

Update, 2:48 PM ET: Added response from Meta, which confirmed it has closed the accounts and groups connected to Mr. Lizhi.

Update, July 7, 6:56 p.m. ET: In a written statement, PayPal said it continually works to combat and prevent the illicit use of its services.

“We devote significant resources globally to financial crime compliance, and we proactively refer cases to and assist law enforcement officials around the world in their efforts to identify, investigate and stop illegal activity,” the statement reads.

Late last year, security researchers made a startling discovery: Kremlin-backed disinformation campaigns were bypassing moderation on social media platforms by leveraging the same malicious advertising technology that powers a sprawling ecosystem of online hucksters and website hackers. A new report on the fallout from that investigation finds this dark ad tech industry is far more resilient and incestuous than previously known.

In November 2024, researchers at the security firm Qurium published an investigation into “Doppelganger,” a disinformation network that promotes pro-Russian narratives and infiltrates Europe’s media landscape by pushing fake news through a network of cloned websites.

Doppelganger campaigns use specialized links that bounce the visitor’s browser through a long series of domains before the fake news content is served. Qurium found Doppelganger relies on a sophisticated “domain cloaking” service, a technology that allows websites to present different content to search engines compared to what regular visitors see. The use of cloaking services helps the disinformation sites remain online longer than they otherwise would, while ensuring that only the targeted audience gets to view the intended content.

Qurium discovered that Doppelganger’s cloaking service also promoted online dating sites, and shared much of the same infrastructure with VexTrio, which is thought to be the oldest malicious traffic distribution system (TDS) in existence. While TDSs are commonly used by legitimate advertising networks to manage traffic from disparate sources and to track who or what is behind each click, VexTrio’s TDS largely manages web traffic from victims of phishing, malware, and social engineering scams.

BREAKING BAD

Digging deeper, Qurium noticed Doppelganger’s cloaking service used an Internet provider in Switzerland as the first entry point in a chain of domain redirections. They also noticed the same infrastructure hosted a pair of co-branded affiliate marketing services that were driving traffic to sketchy adult dating sites: LosPollos[.]com and TacoLoco[.]co.

The LosPollos ad network incorporates many elements and references from the hit series “Breaking Bad,” mirroring the fictional “Los Pollos Hermanos” restaurant chain that served as a money laundering operation for a violent methamphetamine cartel.

Affiliates who sign up with LosPollos are given JavaScript-heavy “smartlinks” that drive traffic into the VexTrio TDS, which in turn distributes the traffic among a variety of advertising partners, including dating services, sweepstakes offers, bait-and-switch mobile apps, financial scams and malware download sites.

LosPollos affiliates typically stitch these smart links into WordPress websites that have been hacked via known vulnerabilities, and those affiliates will earn a small commission each time an Internet user referred by any of their hacked sites falls for one of these lures.

According to Qurium, TacoLoco is a traffic monetization network that uses deceptive tactics to trick Internet users into enabling “push notifications,” a cross-platform browser standard that allows websites to show pop-up messages which appear outside of the browser. For example, on Microsoft Windows systems these notifications typically show up in the bottom right corner of the screen — just above the system clock.

In the case of VexTrio and TacoLoco, the notification approval requests themselves are deceptive — disguised as “CAPTCHA” challenges designed to distinguish automated bot traffic from real visitors. For years, VexTrio and its partners have successfully tricked countless users into enabling these site notifications, which are then used to continuously pepper the victim’s device with a variety of phony virus alerts and misleading pop-up messages.

According to a December 2024 annual report from GoDaddy, nearly 40 percent of compromised websites in 2024 redirected visitors to VexTrio via LosPollos smartlinks.

ADSPRO AND TEKNOLOGY

On November 14, 2024, Qurium published research to support its findings that LosPollos and TacoLoco were services operated by Adspro Group, a company registered in the Czech Republic and Russia, and that Adspro runs its infrastructure at the Swiss hosting providers C41 and Teknology SA.

Qurium noted the LosPollos and TacoLoco sites state that their content is copyrighted by ByteCore AG and SkyForge Digital AG, both Swiss firms that are run by the owner of Teknology SA, Giulio Vitorrio Leonardo Cerutti. Further investigation revealed LosPollos and TacoLoco were apps developed by a company called Holacode, which lists Cerutti as its CEO.

The apps marketed by Holacode include numerous VPN services, as well as one called Spamshield that claims to stop unwanted push notifications. But in January, Infoblox said they tested the app on their own mobile devices, and found it hides the user’s notifications, and then after 24 hours stops hiding them and demands payment. Spamshield subsequently changed its developer name from Holacode to ApLabz, although Infoblox noted that the Terms of Service for several of the rebranded ApLabz apps still referenced Holacode in their terms of service.

Incredibly, Cerutti threatened to sue me for defamation before I’d even uttered his name or sent him a request for comment (Cerutti sent the unsolicited legal threat back in January after his company and my name were merely tagged in an Infoblox post on LinkedIn about VexTrio).

Asked to comment on the findings by Qurium and Infoblox, Cerutti vehemently denied being associated with VexTrio. Cerutti asserted that his companies all strictly adhere to the regulations of the countries in which they operate, and that they have been completely transparent about all of their operations.

“We are a group operating in the advertising and marketing space, with an affiliate network program,” Cerutti responded. “I am not [going] to say we are perfect, but I strongly declare we have no connection with VexTrio at all.”

“Unfortunately, as a big player in this space we also get to deal with plenty of publisher fraud, sketchy traffic, fake clicks, bots, hacked, listed and resold publisher accounts, etc, etc.,” Cerutti continued. “We bleed lots of money to such malpractices and conduct regular internal screenings and audits in a constant battle to remove bad traffic sources. It is also a highly competitive space, where some upstarts will often play dirty against more established mainstream players like us.”

Working with Qurium, researchers at the security firm Infoblox released details about VexTrio’s infrastructure to their industry partners. Just four days after Qurium published its findings, LosPollos announced it was suspending its push monetization service. Less than a month later, Adspro had rebranded to Aimed Global.

A REVEALING PIVOT

In March 2025, researchers at GoDaddy chronicled how DollyWay — a malware strain that has consistently redirected victims to VexTrio throughout its eight years of activity — suddenly stopped doing that on November 20, 2024. Virtually overnight, DollyWay and several other malware families that had previously used VexTrio began pushing their traffic through another TDS called Help TDS.

Digging further into historical DNS records and the unique code scripts used by the Help TDS, Infoblox determined it has long enjoyed an exclusive relationship with VexTrio (at least until LosPollos ended its push monetization service in November).

In a report released today, Infoblox said an exhaustive analysis of the JavaScript code, website lures, smartlinks and DNS patterns used by VexTrio and Help TDS linked them with at least four other TDS operators (not counting TacoLoco). Those four entities — Partners House, BroPush, RichAds and RexPush — are all Russia-based push monetization programs that pay affiliates to drive signups for a variety of schemes, but mostly online dating services.

“As Los Pollos push monetization ended, we’ve seen an increase in fake CAPTCHAs that drive user acceptance of push notifications, particularly from Partners House,” the Infoblox report reads. “The relationship of these commercial entities remains a mystery; while they are certainly long-time partners redirecting traffic to one another, and they all have a Russian nexus, there is no overt common ownership.”

Renee Burton, vice president of threat intelligence at Infoblox, said the security industry generally treats the deceptive methods used by VexTrio and other malicious TDSs as a kind of legally grey area that is mostly associated with less dangerous security threats, such as adware and scareware.

But Burton argues that this view is myopic, and helps perpetuate a dark adtech industry that also pushes plenty of straight-up malware, noting that hundreds of thousands of compromised websites around the world every year redirect victims to the tangled web of VexTrio and VexTrio-affiliate TDSs.

“These TDSs are a nefarious threat, because they’re the ones you can connect to the delivery of things like information stealers and scams that cost consumers billions of dollars a year,” Burton said. “From a larger strategic perspective, my takeaway is that Russian organized crime has control of malicious adtech, and these are just some of the many groups involved.”

WHAT CAN YOU DO?

As KrebsOnSecurity warned way back in 2020, it’s a good idea to be very sparing in approving notifications when browsing the Web. In many cases these notifications are benign, but as we’ve seen there are numerous dodgy firms that are paying site owners to install their notification scripts, and then reselling that communications pathway to scammers and online hucksters.

If you’d like to prevent sites from ever presenting notification requests, all of the major browser makers let you do this — either across the board or on a per-website basis. While it is true that blocking notifications entirely can break the functionality of some websites, doing this for any devices you manage on behalf of your less tech-savvy friends or family members might end up saving everyone a lot of headache down the road.

To modify site notification settings in Mozilla Firefox, navigate to Settings, Privacy & Security, Permissions, and click the “Settings” tab next to “Notifications.” That page will display any notifications already permitted and allow you to edit or delete any entries.

The U.S. government today imposed economic sanctions on Funnull Technology Inc., a Philippines-based company that provides computer infrastructure for hundreds of thousands of websites involved in virtual currency investment scams known as “pig butchering.” In January 2025, KrebsOnSecurity detailed how Funnull was being used as a content delivery network that catered to cybercriminals seeking to route their traffic through U.S.-based cloud providers.

“Americans lose billions of dollars annually to these cyber scams, with revenues generated from these crimes rising to record levels in 2024,” reads a statement from the U.S. Department of the Treasury, which sanctioned Funnull and its 40-year-old Chinese administrator Liu Lizhi. “Funnull has directly facilitated several of these schemes, resulting in over $200 million in U.S. victim-reported losses.”

The Treasury Department said Funnull’s operations are linked to the majority of virtual currency investment scam websites reported to the FBI. The agency said Funnull directly facilitated pig butchering and other schemes that resulted in more than $200 million in financial losses by Americans.

Pig butchering is a rampant form of fraud wherein people are lured by flirtatious strangers online into investing in fraudulent cryptocurrency trading platforms. Victims are coached to invest more and more money into what appears to be an extremely profitable trading platform, only to find their money is gone when they wish to cash out.

The scammers often insist that investors pay additional “taxes” on their crypto “earnings” before they can see their invested funds again (spoiler: they never do), and a shocking number of people have lost six figures or more through these pig butchering scams.

KrebsOnSecurity’s January story on Funnull was based on research from the security firm Silent Push, which discovered in October 2024 that a vast number of domains hosted via Funnull were promoting gambling sites that bore the logo of the Suncity Group, a Chinese entity named in a 2024 UN report (PDF) for laundering millions of dollars for the North Korean state-sponsored hacking group Lazarus.

Silent Push found Funnull was a criminal content delivery network (CDN) that carried a great deal of traffic tied to scam websites, funneling the traffic through a dizzying chain of auto-generated domain names and U.S.-based cloud providers before redirecting to malicious or phishous websites. The FBI has released a technical writeup (PDF) of the infrastructure used to manage the malicious Funnull domains between October 2023 and April 2025.

Silent Push revisited Funnull’s infrastructure in January 2025 and found Funnull was still using many of the same Amazon and Microsoft cloud Internet addresses identified as malicious in its October report. Both Amazon and Microsoft pledged to rid their networks of Funnull’s presence following that story, but according to Silent Push’s Zach Edwards only one of those companies has followed through.

Edwards said Silent Push no longer sees Microsoft Internet addresses showing up in Funnull’s infrastructure, while Amazon continues to struggle with removing Funnull servers, including one that appears to have first materialized in 2023.

“Amazon is doing a terrible job — every day since they made those claims to you and us in our public blog they have had IPs still mapped to Funnull, including some that have stayed mapped for inexplicable periods of time,” Edwards said.

Amazon said its Amazon Web Services (AWS) hosting platform actively counters abuse attempts.

“We have stopped hundreds of attempts this year related to this group and we are looking into the information you shared earlier today,” reads a statement shared by Amazon. “If anyone suspects that AWS resources are being used for abusive activity, they can report it to AWS Trust & Safety using the report abuse form here.”

U.S. based cloud providers remain an attractive home base for cybercriminal organizations because many organizations will not be overly aggressive in blocking traffic from U.S.-based cloud networks, as doing so can result in blocking access to many legitimate web destinations that are also on that same shared network segment or host.

What’s more, funneling their bad traffic so that it appears to be coming out of U.S. cloud Internet providers allows cybercriminals to connect to websites from web addresses that are geographically close(r) to their targets and victims (to sidestep location-based security controls by your bank, for example).

Funnull is not the only cybercriminal infrastructure-as-a-service provider that was sanctioned this month: On May 20, 2025, the European Union imposed sanctions on Stark Industries Solutions, an ISP that materialized at the start of Russia’s invasion of Ukraine and has been used as a global proxy network that conceals the true source of cyberattacks and disinformation campaigns against enemies of Russia.

In May 2024, KrebsOnSecurity published a deep dive on Stark Industries Solutions that found much of the malicious traffic traversing Stark’s network (e.g. vulnerability scanning and password brute force attacks) was being bounced through U.S.-based cloud providers. My reporting showed how deeply Stark had penetrated U.S. ISPs, and that its co-founder for many years sold “bulletproof” hosting services that told Russian cybercrime forum customers they would proudly ignore any abuse complaints or police inquiries.

That story examined the history of Stark’s co-founders, Moldovan brothers Ivan and Yuri Neculiti, who each denied past involvement in cybercrime or any current involvement in assisting Russian disinformation efforts or cyberattacks. Nevertheless, the EU sanctioned both brothers as well.

The EU said Stark and the Neculti brothers “enabled various Russian state-sponsored and state-affiliated actors to conduct destabilising activities including coordinated information manipulation and interference and cyber-attacks against the Union and third countries by providing services intended to hide these activities from European law enforcement and security agencies.”

Authorities in Pakistan have arrested 21 individuals accused of operating “Heartsender,” a once popular spam and malware dissemination service that operated for more than a decade. The main clientele for HeartSender were organized crime groups that tried to trick victim companies into making payments to a third party, and its alleged proprietors were publicly identified by KrebsOnSecurity in 2021 after they inadvertently infected their computers with malware.

A report from the Pakistani media outlet Dawn states that authorities there arrested 21 people alleged to have operated Heartsender, a spam delivery service whose homepage openly advertised phishing kits targeting users of various Internet companies, including Microsoft 365, Yahoo, AOL, Intuit, iCloud and ID.me. Pakistan’s National Cyber Crime Investigation Agency (NCCIA) reportedly conducted raids in Lahore’s Bahria Town and Multan on May 15 and 16.

The NCCIA told reporters the group’s tools were connected to more than $50m in losses in the United States alone, with European authorities investigating 63 additional cases.

“This wasn’t just a scam operation – it was essentially a cybercrime university that empowered fraudsters globally,” NCCIA Director Abdul Ghaffar said at a press briefing.

In January 2025, the FBI and the Dutch Police seized the technical infrastructure for the cybercrime service, which was marketed under the brands Heartsender, Fudpage and Fudtools (and many other “fud” variations). The “fud” bit stands for “Fully Un-Detectable,” and it refers to cybercrime resources that will evade detection by security tools like antivirus software or anti-spam appliances.

The FBI says transnational organized crime groups that purchased these services primarily used them to run business email compromise (BEC) schemes, wherein the cybercrime actors tricked victim companies into making payments to a third party.

Dawn reported that those arrested included Rameez Shahzad, the alleged ringleader of the Heartsender cybercrime business, which most recently operated under the Pakistani front company WeCodeSolutions. Mr. Shahzad was named and pictured in a 2021 KrebsOnSecurity story about a series of remarkable operational security mistakes that exposed their identities and Facebook pages showing employees posing for group photos and socializing at work-related outings.

Prior to folding their operations behind WeCodeSolutions, Shahzad and others arrested this month operated as a web hosting group calling itself The Manipulaters. KrebsOnSecurity first wrote about The Manipulaters in May 2015, mainly because their ads at the time were blanketing a number of popular cybercrime forums, and because they were fairly open and brazen about what they were doing — even who they were in real life.

Sometime in 2019, The Manipulaters failed to renew their core domain name — manipulaters[.]com — the same one tied to so many of the company’s business operations. That domain was quickly scooped up by Scylla Intel, a cyber intelligence firm that specializes in connecting cybercriminals to their real-life identities. Soon after, Scylla started receiving large amounts of email correspondence intended for the group’s owners.

In 2024, DomainTools.com found the web-hosted version of Heartsender leaked an extraordinary amount of user information to unauthenticated users, including customer credentials and email records from Heartsender employees. DomainTools says the malware infections on Manipulaters PCs exposed “vast swaths of account-related data along with an outline of the group’s membership, operations, and position in the broader underground economy.”

Shahzad allegedly used the alias “Saim Raza,” an identity which has contacted KrebsOnSecurity multiple times over the past decade with demands to remove stories published about the group. The Saim Raza identity most recently contacted this author in November 2024, asserting they had quit the cybercrime industry and turned over a new leaf after a brush with the Pakistani police.

The arrested suspects include Rameez Shahzad, Muhammad Aslam (Rameez’s father), Atif Hussain, Muhammad Umar Irshad, Yasir Ali, Syed Saim Ali Shah, Muhammad Nowsherwan, Burhanul Haq, Adnan Munawar, Abdul Moiz, Hussnain Haider, Bilal Ahmad, Dilbar Hussain, Muhammad Adeel Akram, Awais Rasool, Usama Farooq, Usama Mehmood and Hamad Nawaz.

The U.S. government today unsealed criminal charges against 16 individuals accused of operating and selling DanaBot, a prolific strain of information-stealing malware that has been sold on Russian cybercrime forums since 2018. The FBI says a newer version of DanaBot was used for espionage, and that many of the defendants exposed their real-life identities after accidentally infecting their own systems with the malware.

Initially spotted in May 2018 by researchers at the email security firm Proofpoint, DanaBot is a malware-as-a-service platform that specializes in credential theft and banking fraud.

Today, the U.S. Department of Justice unsealed a criminal complaint and indictment from 2022, which said the FBI identified at least 40 affiliates who were paying between $3,000 and $4,000 a month for access to the information stealer platform.

The government says the malware infected more than 300,000 systems globally, causing estimated losses of more than $50 million. The ringleaders of the DanaBot conspiracy are named as Aleksandr Stepanov, 39, a.k.a. “JimmBee,” and Artem Aleksandrovich Kalinkin, 34, a.k.a. “Onix”, both of Novosibirsk, Russia. Kalinkin is an IT engineer for the Russian state-owned energy giant Gazprom. His Facebook profile name is “Maffiozi.”

According to the FBI, there were at least two major versions of DanaBot; the first was sold between 2018 and June 2020, when the malware stopped being offered on Russian cybercrime forums. The government alleges that the second version of DanaBot — emerging in January 2021 — was provided to co-conspirators for use in targeting military, diplomatic and non-governmental organization computers in several countries, including the United States, Belarus, the United Kingdom, Germany, and Russia.

“Unindicted co-conspirators would use the Espionage Variant to compromise computers around the world and steal sensitive diplomatic communications, credentials, and other data from these targeted victims,” reads a grand jury indictment dated Sept. 20, 2022. “This stolen data included financial transactions by diplomatic staff, correspondence concerning day-to-day diplomatic activity, as well as summaries of a particular country’s interactions with the United States.”

The indictment says the FBI in 2022 seized servers used by the DanaBot authors to control their malware, as well as the servers that stored stolen victim data. The government said the server data also show numerous instances in which the DanaBot defendants infected their own PCs, resulting in their credential data being uploaded to stolen data repositories that were seized by the feds.

“In some cases, such self-infections appeared to be deliberately done in order to test, analyze, or improve the malware,” the criminal complaint reads. “In other cases, the infections seemed to be inadvertent – one of the hazards of committing cybercrime is that criminals will sometimes infect themselves with their own malware by mistake.”

A statement from the DOJ says that as part of today’s operation, agents with the Defense Criminal Investigative Service (DCIS) seized the DanaBot control servers, including dozens of virtual servers hosted in the United States. The government says it is now working with industry partners to notify DanaBot victims and help remediate infections. The statement credits a number of security firms with providing assistance to the government, including ESET, Flashpoint, Google, Intel 471, Lumen, PayPal, Proofpoint, Team CYMRU, and ZScaler.

It’s not unheard of for financially-oriented malicious software to be repurposed for espionage. A variant of the ZeuS Trojan, which was used in countless online banking attacks against companies in the United States and Europe between 2007 and at least 2015, was for a time diverted to espionage tasks by its author.

As detailed in this 2015 story, the author of the ZeuS trojan created a custom version of the malware to serve purely as a spying machine, which scoured infected systems in Ukraine for specific keywords in emails and documents that would likely only be found in classified documents.

The public charging of the 16 DanaBot defendants comes a day after Microsoft joined a slew of tech companies in disrupting the IT infrastructure for another malware-as-a-service offering — Lumma Stealer, which is likewise offered to affiliates under tiered subscription prices ranging from $250 to $1,000 per month. Separately, Microsoft filed a civil lawsuit to seize control over 2,300 domain names used by Lumma Stealer and its affiliates.

September 2022 grand jury indictment naming the 16 defendants

KrebsOnSecurity last week was hit by a near record distributed denial-of-service (DDoS) attack that clocked in at more than 6.3 terabits of data per second (a terabit is one trillion bits of data). The brief attack appears to have been a test run for a massive new Internet of Things (IoT) botnet capable of launching crippling digital assaults that few web destinations can withstand. Read on for more about the botnet, the attack, and the apparent creator of this global menace.

For reference, the 6.3 Tbps attack last week was ten times the size of the assault launched against this site in 2016 by the Mirai IoT botnet, which held KrebsOnSecurity offline for nearly four days. The 2016 assault was so large that Akamai – which was providing pro-bono DDoS protection for KrebsOnSecurity at the time — asked me to leave their service because the attack was causing problems for their paying customers.

Since the Mirai attack, KrebsOnSecurity.com has been behind the protection of Project Shield, a free DDoS defense service that Google provides to websites offering news, human rights, and election-related content. Google Security Engineer Damian Menscher told KrebsOnSecurity the May 12 attack was the largest Google has ever handled. In terms of sheer size, it is second only to a very similar attack that Cloudflare mitigated and wrote about in April.

After comparing notes with Cloudflare, Menscher said the botnet that launched both attacks bears the fingerprints of Aisuru, a digital siege machine that first surfaced less than a year ago. Menscher said the attack on KrebsOnSecurity lasted less than a minute, hurling large UDP data packets at random ports at a rate of approximately 585 million data packets per second.

“It was the type of attack normally designed to overwhelm network links,” Menscher said, referring to the throughput connections between and among various Internet service providers (ISPs). “For most companies, this size of attack would kill them.”

The Aisuru botnet comprises a globally-dispersed collection of hacked IoT devices, including routers, digital video recorders and other systems that are commandeered via default passwords or software vulnerabilities. As documented by researchers at QiAnXin XLab, the botnet was first identified in an August 2024 attack on a large gaming platform.

Aisuru reportedly went quiet after that exposure, only to reappear in November with even more firepower and software exploits. In a January 2025 report, XLab found the new and improved Aisuru (a.k.a. “Airashi“) had incorporated a previously unknown zero-day vulnerability in Cambium Networks cnPilot routers.

NOT FORKING AROUND

The people behind the Aisuru botnet have been peddling access to their DDoS machine in public Telegram chat channels that are closely monitored by multiple security firms. In August 2024, the botnet was rented out in subscription tiers ranging from $150 per day to $600 per week, offering attacks of up to two terabits per second.

“You may not attack any measurement walls, healthcare facilities, schools or government sites,” read a notice posted on Telegram by the Aisuru botnet owners in August 2024.

Interested parties were told to contact the Telegram handle “@yfork” to purchase a subscription. The account @yfork previously used the nickname “Forky,” an identity that has been posting to public DDoS-focused Telegram channels since 2021.

According to the FBI, Forky’s DDoS-for-hire domains have been seized in multiple law enforcement operations over the years. Last year, Forky said on Telegram he was selling the domain stresser[.]best, which saw its servers seized by the FBI in 2022 as part of an ongoing international law enforcement effort aimed at diminishing the supply of and demand for DDoS-for-hire services.

“The operator of this service, who calls himself ‘Forky,’ operates a Telegram channel to advertise features and communicate with current and prospective DDoS customers,” reads an FBI seizure warrant (PDF) issued for stresser[.]best. The FBI warrant stated that on the same day the seizures were announced, Forky posted a link to a story on this blog that detailed the domain seizure operation, adding the comment, “We are buying our new domains right now.”

Approximately ten hours later, Forky posted again, including a screenshot of the stresser[.]best user dashboard, instructing customers to use their saved passwords for the old website on the new one.

A review of Forky’s posts to public Telegram channels — as indexed by the cyber intelligence firms Unit 221B and Flashpoint — reveals a 21-year-old individual who claims to reside in Brazil [full disclosure: Flashpoint is currently an advertiser on this blog].

Since late 2022, Forky’s posts have frequently promoted a DDoS mitigation company and ISP that he operates called botshield[.]io. The Botshield website is connected to a business entity registered in the United Kingdom called Botshield LTD, which lists a 21-year-old woman from Sao Paulo, Brazil as the director. Internet routing records indicate Botshield (AS213613) currently controls several hundred Internet addresses that were allocated to the company earlier this year.

Domaintools.com reports that botshield[.]io was registered in July 2022 to a Kaike Southier Leite in Sao Paulo. A LinkedIn profile by the same name says this individual is a network specialist from Brazil who works in “the planning and implementation of robust network infrastructures, with a focus on security, DDoS mitigation, colocation and cloud server services.”

MEET FORKY

In his posts to public Telegram chat channels, Forky has hardly attempted to conceal his whereabouts or identity. In countless chat conversations indexed by Unit 221B, Forky could be seen talking about everyday life in Brazil, often remarking on the extremely low or high prices in Brazil for a range of goods, from computer and networking gear to narcotics and food.

Reached via Telegram, Forky claimed he was “not involved in this type of illegal actions for years now,” and that the project had been taken over by other unspecified developers. Forky initially told KrebsOnSecurity he had been out of the botnet scene for years, only to concede this wasn’t true when presented with public posts on Telegram from late last year that clearly showed otherwise.

Forky denied being involved in the attack on KrebsOnSecurity, but acknowledged that he helped to develop and market the Aisuru botnet. Forky claims he is now merely a staff member for the Aisuru botnet team, and that he stopped running the botnet roughly two months ago after starting a family. Forky also said the woman named as director of Botshield is related to him.

Forky offered equivocal, evasive responses to a number of questions about the Aisuru botnet and his business endeavors. But on one point he was crystal clear:

“I have zero fear about you, the FBI, or Interpol,” Forky said, asserting that he is now almost entirely focused on their hosting business — Botshield.

Forky declined to discuss the makeup of his ISP’s clientele, or to clarify whether Botshield was more of a hosting provider or a DDoS mitigation firm. However, Forky has posted on Telegram about Botshield successfully mitigating large DDoS attacks launched against other DDoS-for-hire services.

DomainTools finds the same Sao Paulo street address in the registration records for botshield[.]io was used to register several other domains, including cant-mitigate[.]us. The email address in the WHOIS records for that domain is forkcontato@gmail.com, which DomainTools says was used to register the domain for the now-defunct DDoS-for-hire service stresser[.]us, one of the domains seized in the FBI’s 2023 crackdown.

On May 8, 2023, the U.S. Department of Justice announced the seizure of stresser[.]us, along with a dozen other domains offering DDoS services. The DOJ said ten of the 13 domains were reincarnations of services that were seized during a prior sweep in December, which targeted 48 top stresser services (also known as “booters”).

Forky claimed he could find out who attacked my site with Aisuru. But when pressed a day later on the question, Forky said he’d come up empty-handed.

“I tried to ask around, all the big guys are not retarded enough to attack you,” Forky explained in an interview on Telegram. “I didn’t have anything to do with it. But you are welcome to write the story and try to put the blame on me.”

THE GHOST OF MIRAI

The 6.3 Tbps attack last week caused no visible disruption to this site, in part because it was so brief — lasting approximately 45 seconds. DDoS attacks of such magnitude and brevity typically are produced when botnet operators wish to test or demonstrate their firepower for the benefit of potential buyers. Indeed, Google’s Menscher said it is likely that both the May 12 attack and the slightly larger 6.5 Tbps attack against Cloudflare last month were simply tests of the same botnet’s capabilities.

In many ways, the threat posed by the Aisuru/Airashi botnet is reminiscent of Mirai, an innovative IoT malware strain that emerged in the summer of 2016 and successfully out-competed virtually all other IoT malware strains in existence at the time.

As first revealed by KrebsOnSecurity in January 2017, the Mirai authors were two U.S. men who co-ran a DDoS mitigation service — even as they were selling far more lucrative DDoS-for-hire services using the most powerful botnet on the planet.

Less than a week after the Mirai botnet was used in a days-long DDoS against KrebsOnSecurity, the Mirai authors published the source code to their botnet so that they would not be the only ones in possession of it in the event of their arrest by federal investigators.

Ironically, the leaking of the Mirai source is precisely what led to the eventual unmasking and arrest of the Mirai authors, who went on to serve probation sentences that required them to consult with FBI investigators on DDoS investigations. But that leak also rapidly led to the creation of dozens of Mirai botnet clones, many of which were harnessed to fuel their own powerful DDoS-for-hire services.

Menscher told KrebsOnSecurity that as counterintuitive as it may sound, the Internet as a whole would probably be better off if the source code for Aisuru became public knowledge. After all, he said, the people behind Aisuru are in constant competition with other IoT botnet operators who are all striving to commandeer a finite number of vulnerable IoT devices globally.

Such a development would almost certainly cause a proliferation of Aisuru botnet clones, he said, but at least then the overall firepower from each individual botnet would be greatly diminished — or at least within range of the mitigation capabilities of most DDoS protection providers.

Barring a source code leak, Menscher said, it would be nice if someone published the full list of software exploits being used by the Aisuru operators to grow their botnet so quickly.

“Part of the reason Mirai was so dangerous was that it effectively took out competing botnets,” he said. “This attack somehow managed to compromise all these boxes that nobody else knows about. Ideally, we’d want to see that fragmented out, so that no [individual botnet operator] controls too much.”

In what experts are calling a novel legal outcome, the 22-year-old former administrator of the cybercrime community Breachforums will forfeit nearly $700,000 to settle a civil lawsuit from a health insurance company whose customer data was posted for sale on the forum in 2023. Conor Brian Fitzpatrick, a.k.a. “Pompompurin,” is slated for resentencing next month after pleading guilty to access device fraud and possession of child sexual abuse material (CSAM).

On January 18, 2023, denizens of Breachforums posted for sale tens of thousands of records — including Social Security numbers, dates of birth, addresses, and phone numbers  — stolen from Nonstop Health, an insurance provider based in Concord, Calif.

Class-action attorneys sued Nonstop Health, which added Fitzpatrick as a third-party defendant to the civil litigation in November 2023, several months after he was arrested by the FBI and criminally charged with access device fraud and CSAM possession. In January 2025, Nonstop agreed to pay $1.5 million to settle the class action.

Jill Fertel is a former prosecutor who runs the cyber litigation practice at Cipriani & Werner, the law firm that represented Nonstop Health. Fertel told KrebsOnSecurity this is the first and only case where a cybercriminal or anyone related to the security incident was actually named in civil litigation.

“Civil plaintiffs are not at all likely to see money seized from threat actors involved in the incident to be made available to people impacted by the breach,” Fertel said. “The best we could do was make this money available to the class, but it’s still incumbent on the members of the class who are impacted to make that claim.”

Mark Rasch is a former federal prosecutor who now represents Unit 221B, a cybersecurity firm based in New York City. Rasch said he doesn’t doubt that the civil settlement involving Fitzpatrick’s criminal activity is a novel legal development.

“It is rare in these civil cases that you know the threat actor involved in the breach, and it’s also rare that you catch them with sufficient resources to be able to pay a claim,” Rasch said.

Despite admitting to possessing more than 600 CSAM images and personally operating Breachforums, Fitzpatrick was sentenced in January 2024 to time served and 20 years of supervised release. Federal prosecutors objected, arguing that his punishment failed to adequately reflect the seriousness of his crimes or serve as a deterrent.

Indeed, the same month he was sentenced Fitzpatrick was rearrested (PDF) for violating the terms of his release, which forbade him from using a computer that didn’t have court-required monitoring software installed.

Federal prosecutors said Fitzpatrick went on Discord following his guilty plea and professed innocence to the very crimes to which he’d pleaded guilty, stating that his plea deal was “so BS” and that he had “wanted to fight it.” The feds said Fitzpatrick also joked with his friends about selling data to foreign governments, exhorting one user to “become a foreign asset to china or russia,” and to “sell government secrets.”

In January 2025, a federal appeals court agreed with the government’s assessment, vacating Fitzpatrick’s sentence and ordering him to be resentenced on June 3, 2025.

Fitzpatrick launched BreachForums in March 2022 to replace RaidForums, a similarly popular crime forum that was infiltrated and shut down by the FBI the previous month. As administrator, his alter ego Pompompurin served as the middleman, personally reviewing all databases for sale on the forum and offering an escrow service to those interested in buying stolen data.

The new site quickly attracted more than 300,000 users, and facilitated the sale of databases stolen from hundreds of hacking victims, including some of the largest consumer data breaches in recent history. In May 2024, a reincarnation of Breachforums was seized by the FBI and international partners. Still more relaunches of the forum occurred after that, with the most recent disruption last month.

As KrebsOnSecurity reported last year in The Dark Nexus Between Harm Groups and The Com, it is increasingly common for federal investigators to find CSAM material when searching devices seized from cybercriminal suspects. While the mere possession of CSAM is a serious federal crime, not all of those caught with CSAM are necessarily creators or distributors of it. Fertel said some cybercriminal communities have been known to require new entrants to share CSAM material as a way of proving that they are not a federal investigator.

“If you’re going to the darkest corners of Internet, that’s how you prove you’re not law enforcement,” Fertel said. “Law enforcement would never share that material. It would be criminal for me as a prosecutor, if I obtained and possessed those types of images.”

Further reading: The settlement between Fitzpatrick and Nonstop (PDF).

A Texas firm recently charged with conspiring to distribute synthetic opioids in the United States is at the center of a vast network of companies in the U.S. and Pakistan whose employees are accused of using online ads to scam westerners seeking help with trademarks, book writing, mobile app development and logo designs, a new investigation reveals.

In an indictment (PDF) unsealed last month, the U.S. Department of Justice said Dallas-based eWorldTrade “operated an online business-to-business marketplace that facilitated the distribution of synthetic opioids such as isotonitazene and carfentanyl, both significantly more potent than fentanyl.”

Launched in 2017, eWorldTrade[.]com now features a seizure notice from the DOJ. eWorldTrade operated as a wholesale seller of consumer goods, including clothes, machinery, chemicals, automobiles and appliances. The DOJ’s indictment includes no additional details about eWorldTrade’s business, origins or other activity, and at first glance the website might appear to be a legitimate e-commerce platform that also just happened to sell some restricted chemicals.

However, an investigation into the company’s founders reveals they are connected to a sprawling network of websites that have a history of extortionate scams involving trademark registration, book publishing, exam preparation, and the design of logos, mobile applications and websites.

Records from the U.S. Patent and Trademark Office (USPTO) show the eWorldTrade mark is owned by an Azneem Bilwani in Karachi (this name also is in the registration records for the now-seized eWorldTrade domain). Mr. Bilwani is perhaps better known as the director of the Pakistan-based IT provider Abtach Ltd., which has been singled out by the USPTO and Google for operating trademark registration scams (the main offices for eWorldtrade and Abtach share the same address in Pakistan).

In November 2021, the USPTO accused Abtach of perpetrating “an egregious scheme to deceive and defraud applicants for federal trademark registrations by improperly altering official USPTO correspondence, overcharging application filing fees, misappropriating the USPTO’s trademarks, and impersonating the USPTO.”

Abtach offered trademark registration at suspiciously low prices compared to legitimate costs of over USD $1,500, and claimed they could register a trademark in 24 hours. Abtach reportedly rebranded to Intersys Limited after the USPTO banned Abtach from filing any more trademark applications.

FROM AXACT TO ABTACH

Many of Abtach’s employees are former associates of a similar company in Pakistan called Axact that was targeted by Pakistani authorities in a 2015 fraud investigation. Axact came under law enforcement scrutiny after The New York Times ran a front-page story about the company’s most lucrative scam business: Hundreds of sites peddling fake college degrees and diplomas.

People who purchased fake certifications were subsequently blackmailed by Axact employees posing as government officials, who would demand additional payments under threats of prosecution or imprisonment for having bought fraudulent “unauthorized” academic degrees. This practice created a continuous cycle of extortion, internally referred to as “upselling.”

“Axact took money from at least 215,000 people in 197 countries — one-third of them from the United States,” The Times reported. “Sales agents wielded threats and false promises and impersonated government officials, earning the company at least $89 million in its final year of operation.”

Dozens of top Axact employees were arrested, jailed, held for months, tried and sentenced to seven years for various fraud violations. But a 2019 research brief on Axact’s diploma mills found none of those convicted had started their prison sentence, and that several had fled Pakistan and never returned.

“In October 2016, a Pakistan district judge acquitted 24 Axact officials at trial due to ‘not enough evidence’ and then later admitted he had accepted a bribe (of $35,209) from Axact,” reads a history (PDF) published by the American Association of Collegiate Registrars and Admissions Officers.

In 2021, Pakistan’s Federal Investigation Agency (FIA) charged Bilwani and nearly four dozen others — many of them Abtach employees — with running an elaborate trademark scam. The authorities called it “the biggest money laundering case in the history of Pakistan,” and named a number of businesses based in Texas that allegedly helped move the proceeds of cybercrime.

The FIA said the defendants operated a large number of websites offering low-cost trademark services to customers, before then “ignoring them after getting the funds and later demanding more funds from clients/victims in the name of up-sale (extortion).” The Pakistani law enforcement agency said that about 75 percent of customers received fake or fabricated trademarks as a result of the scams.

The FIA found Abtach operates in conjunction with a Karachi firm called Digitonics Labs, which earned a monthly revenue of around $2.5 million through the “extortion of international clients in the name of up-selling, the sale of fake/fabricated USPTO certificates, and the maintaining of phishing websites.”

According the Pakistani authorities, the accused also ran countless scams involving ebook publication and logo creation, wherein customers are subjected to advance-fee fraud and extortion — with the scammers demanding more money for supposed “copyright release” and threatening to release the trademark.

Also charged by the FIA was Junaid Mansoor, the owner of Digitonics Labs in Karachi. Mansoor’s U.K.-registered company Maple Solutions Direct Limited has run at least 700 ads for logo design websites since 2015, the Google Ads Transparency page reports. The company has approximately 88 ads running on Google as of today. 

Mr. Mansoor is actively involved with and promoting a Quran study business called quranmasteronline[.]com, which was founded by Junaid’s brother Qasim Mansoor (Qasim is also named in the FIA criminal investigation). The Google ads promoting quranmasteronline[.]com were paid for by the same account advertising a number of scam websites selling logo and web design services. 

Junaid Mansoor did not respond to requests for comment. An address in Teaneck, New Jersey where Mr. Mansoor previously lived is listed as an official address of exporthub[.]com, a Pakistan-based e-commerce website that appears remarkably similar to eWorldTrade (Exporthub says its offices are in Texas). Interestingly, a search in Google for this domain shows ExportHub currently features multiple listings for fentanyl citrate from suppliers in China and elsewhere.

The CEO of Digitonics Labs is Muhammad Burhan Mirza, a former Axact official who was arrested by the FIA as part of its money laundering and trademark fraud investigation in 2021. In 2023, prosecutors in Pakistan charged Mirza, Mansoor and 14 other Digitonics employees with fraud, impersonating government officials, phishing, cheating and extortion. Mirza’s LinkedIn profile says he currently runs an educational technology/life coach enterprise called TheCoach360, which purports to help young kids “achieve financial independence.”

Reached via LinkedIn, Mr. Mirza denied having anything to do with eWorldTrade or any of its sister companies in Texas.

“Moreover, I have no knowledge as to the companies you have mentioned,” said Mr. Mirza, who did not respond to follow-up questions.

The current disposition of the FIA’s fraud case against the defendants is unclear. The investigation was marred early on by allegations of corruption and bribery. In 2021, Pakistani authorities alleged Bilwani paid a six-figure bribe to FIA investigators. Meanwhile, attorneys for Mr. Bilwani have argued that although their client did pay a bribe, the payment was solicited by government officials. Mr. Bilwani did not respond to requests for comment.

THE TEXAS NEXUS

KrebsOnSecurity has learned that the people and entities at the center of the FIA investigations have built a significant presence in the United States, with a strong concentration in Texas. The Texas businesses promote websites that sell logo and web design, ghostwriting, and academic cheating services. Many of these entities have recently been sued for fraud and breach of contract by angry former customers, who claimed the companies relentlessly upsold them while failing to produce the work as promised.

For example, the FIA complaints named Retrocube LLC and 360 Digital Marketing LLC, two entities that share a street address with eWorldTrade: 1910 Pacific Avenue, Suite 8025, Dallas, Texas. Also incorporated at that Pacific Avenue address is abtach[.]ae, a web design and marketing firm based in Dubai; and intersyslimited[.]com, the new name of Abtach after they were banned by the USPTO. Other businesses registered at this address market services for logo design, mobile app development, and ghostwriting.

360 Digital Marketing’s website 360digimarketing[.]com is owned by an Abtach front company called Abtech LTD. Meanwhile, business records show 360 Digi Marketing LTD is a U.K. company whose officers include former Abtach director Bilwani; Muhammad Saad Iqbal, formerly Abtach, now CEO of Intersys Ltd; Niaz Ahmed, a former Abtach associate; and Muhammad Salman Yousuf, formerly a vice president at Axact, Abtach, and Digitonics Labs.

Google’s Ads Transparency Center finds 360 Digital Marketing LLC ran at least 500 ads promoting various websites selling ghostwriting services . Another entity tied to Junaid Mansoor — a company called Octa Group Technologies AU — has run approximately 300 Google ads for book publishing services, promoting confusingly named websites like amazonlistinghub[.]com and barnesnoblepublishing[.]co.

Rameez Moiz is a Texas resident and former Abtach product manager who has represented 360 Digital Marketing LLC and RetroCube. Moiz told KrebsOnSecurity he stopped working for 360 Digital Marketing in the summer of 2023. Mr. Moiz did not respond to follow-up questions, but an Upwork profile for him states that as of April 2025 he is employed by Dallas-based Vertical Minds LLC.

In April 2025, California resident Melinda Will sued the Texas firm Majestic Ghostwriting — which is doing business as ghostwritingsquad[.]com —  alleging they scammed her out of $100,000 after she hired them to help write her book. Google’s ad transparency page shows Moiz’s employer Vertical Minds LLC paid to run approximately 55 ads for ghostwritingsquad[.]com and related sites.

VICTIMS SPEAK OUT

Ms. Will’s lawsuit is just one of more than two dozen complaints over the past four years wherein plaintiffs sued one of this group’s web design, wiki editing or ghostwriting services. In 2021, a New Jersey man sued Octagroup Technologies, alleging they ripped him off when he paid a total of more than $26,000 for the design and marketing of a web-based mapping service.

The plaintiff in that case did not respond to requests for comment, but his complaint alleges Octagroup and a myriad other companies it contracted with produced minimal work product despite subjecting him to relentless upselling. That case was decided in favor of the plaintiff because the defendants never contested the matter in court.

In 2023, 360 Digital Marketing LLC and Retrocube LLC were sued by a woman who said they scammed her out of $40,000 over a book she wanted help writing. That lawsuit helpfully showed an image of the office front door at 1910 Pacific Ave Suite 8025, which featured the logos of 360 Digital Marketing, Retrocube, and eWorldTrade.

The lawsuit was filed pro se by Leigh Riley, a 64-year-old career IT professional who paid 360 Digital Marketing to have a company called Talented Ghostwriter co-author and promote a series of books she’d outlined on spirituality and healing.

“The main reason I hired them was because I didn’t understand what I call the formula for writing a book, and I know there’s a lot of marketing that goes into publishing,” Riley explained in an interview. “I know nothing about that stuff, and these guys were convincing that they could handle all aspects of it. Until I discovered they couldn’t write a damn sentence in English properly.”

Riley’s well-documented lawsuit (not linked here because it features a great deal of personal information) includes screenshots of conversations with the ghostwriting team, which was constantly assigning her to new writers and editors, and ghosting her on scheduled conference calls about progress on the project. Riley said she ended up writing most of the book herself because the work they produced was unusable.

“Finally after months of promising the books were printed and on their way, they show up at my doorstep with the wrong title on the book,” Riley said. When she demanded her money back, she said the people helping her with the website to promote the book locked her out of the site.

Riley decided to sue, naming 360 Digital Marketing LLC and Retrocube LLC, among others.  The companies offered to settle the matter for $20,000, which she accepted. “I didn’t have money to hire a lawyer, and I figured it was time to cut my losses,” she said.

Riley said she could have saved herself a great deal of headache by doing some basic research on Talented Ghostwriter, whose website claims the company is based in Los Angeles. According to the California Secretary of State, however, there is no registered entity by that name. Rather, the address claimed by talentedghostwriter[.]com is a vacant office building with a “space available” sign in the window.

California resident Walter Horsting discovered something similar when he sued 360 Digital Marketing in small claims court last year, after hiring a company called Vox Ghostwriting to help write, edit and promote a spy novel he’d been working on. Horsting said he paid Vox $3,300 to ghostwrite a 280-page book, and was upsold an Amazon marketing and publishing package for $7,500.

In an interview, Horsting said the prose that Vox Ghostwriting produced was “juvenile at best,” forcing him to rewrite and edit the work himself, and to partner with a graphical artist to produce illustrations. Horsting said that when it came time to begin marketing the novel, Vox Ghostwriting tried to further upsell him on marketing packages, while dodging scheduled meetings with no follow-up.

“They have a money back guarantee, and when they wouldn’t refund my money I said I’m taking you to court,” Horsting recounted. “I tried to serve them in Los Angeles but found no such office exists. I talked to a salon next door and they said someone else had recently shown up desperately looking for where the ghostwriting company went, and it appears there are a trail of corpses on this. I finally tracked down where they are in Texas.”

It was the same office that Ms. Riley served her lawsuit against. Horsting said he has a court hearing scheduled later this month, but he’s under no illusions that winning the case means he’ll be able to collect.

“At this point, I’m doing it out of pride more than actually expecting anything to come to good fortune for me,” he said.

The following mind map was helpful in piecing together key events, individuals and connections mentioned above. It’s important to note that this graphic only scratches the surface of the operations tied to this group. For example, in Case 2 we can see mention of academic cheating services, wherein people can be hired to take online proctored exams on one’s behalf. Those who hire these services soon find themselves subject to impersonation and blackmail attempts for larger and larger sums of money, with the threat of publicly exposing their unethical academic cheating activity.

GOOGLE RESPONDS

KrebsOnSecurity reviewed the Google Ad Transparency links for nearly 500 different websites tied to this network of ghostwriting, logo, app and web development businesses. Those website names were then fed into spyfu.com, a competitive intelligence company that tracks the reach and performance of advertising keywords. Spyfu estimates that between April 2023 and April 2025, those websites spent more than $10 million on Google ads.

Reached for comment, Google said in a written statement that it is constantly policing its ad network for bad actors, pointing to an ads safety report (PDF) showing Google blocked or removed 5.1 billion bad ads last year — including more than 500 million ads related to trademarks.

“Our policy against Enabling Dishonest Behavior prohibits products or services that help users mislead others, including ads for paper-writing or exam-taking services,” the statement reads. “When we identify ads or advertisers that violate our policies, we take action, including by suspending advertiser accounts, disapproving ads, and restricting ads to specific domains when appropriate.”

Google did not respond to specific questions about the advertising entities mentioned in this story, saying only that “we are actively investigating this matter and addressing any policy violations, including suspending advertiser accounts when appropriate.”

From reviewing the ad accounts that have been promoting these scam websites, it appears Google has very recently acted to remove a large number of the offending ads. Prior to my notifying Google about the extent of this ad network on April 28, the Google Ad Transparency network listed over 500 ads for 360 Digital Marketing; as of this publication, that number had dwindled to 10.

On April 30, Google announced that starting this month its ads transparency page will display the payment profile name as the payer name for verified advertisers, if that name differs from their verified advertiser name. Searchengineland.com writes the changes are aimed at increasing accountability in digital advertising.

This spreadsheet lists the domain names, advertiser names, and Google Ad Transparency links for more than 350 entities offering ghostwriting, publishing, web design and academic cheating services.

A 23-year-old Scottish man thought to be a member of the prolific Scattered Spider cybercrime group was extradited last week from Spain to the United States, where he is facing charges of wire fraud, conspiracy and identity theft. U.S. prosecutors allege Tyler Robert Buchanan and co-conspirators hacked into dozens of companies in the United States and abroad, and that he personally controlled more than $26 million stolen from victims.

Scattered Spider is a loosely affiliated criminal hacking group whose members have broken into and stolen data from some of the world’s largest technology companies. Buchanan was arrested in Spain last year on a warrant from the FBI, which wanted him in connection with a series of SMS-based phishing attacks in the summer of 2022 that led to intrusions at Twilio, LastPass, DoorDash, Mailchimp, and many other tech firms.

As first reported by KrebsOnSecurity, Buchanan (a.k.a. “tylerb”) fled the United Kingdom in February 2023, after a rival cybercrime gang hired thugs to invade his home, assault his mother, and threaten to burn him with a blowtorch unless he gave up the keys to his cryptocurrency wallet. Buchanan was arrested in June 2024 at the airport in Palma de Mallorca while trying to board a flight to Italy. His extradition to the United States was first reported last week by Bloomberg.

Members of Scattered Spider have been tied to the 2023 ransomware attacks against MGM and Caesars casinos in Las Vegas, but it remains unclear whether Buchanan was implicated in that incident. The Justice Department’s complaint against Buchanan makes no mention of the 2023 ransomware attack.

Rather, the investigation into Buchanan appears to center on the SMS phishing campaigns from 2022, and on SIM-swapping attacks that siphoned funds from individual cryptocurrency investors. In a SIM-swapping attack, crooks transfer the target’s phone number to a device they control and intercept any text messages or phone calls to the victim’s device — including one-time passcodes for authentication and password reset links sent via SMS.

In August 2022, KrebsOnSecurity reviewed data harvested in a months-long cybercrime campaign by Scattered Spider involving countless SMS-based phishing attacks against employees at major corporations. The security firm Group-IB called them by a different name — 0ktapus, because the group typically spoofed the identity provider Okta in their phishing messages to employees at targeted firms.

The complaint against Buchanan (PDF) says the FBI tied him to the 2022 SMS phishing attacks after discovering the same username and email address was used to register numerous Okta-themed phishing domains seen in the campaign. The domain registrar NameCheap found that less than a month before the phishing spree, the account that registered those domains logged in from an Internet address in the U.K. FBI investigators said the Scottish police told them the address was leased to Buchanan from January 26, 2022 to November 7, 2022.

Authorities seized at least 20 digital devices when they raided Buchanan’s residence, and on one of those devices they found usernames and passwords for employees of three different companies targeted in the phishing campaign.

“The FBI’s investigation to date has gathered evidence showing that Buchanan and his co-conspirators targeted at least 45 companies in the United States and abroad, including Canada, India, and the United Kingdom,” the FBI complaint reads. “One of Buchanan’s devices contained a screenshot of Telegram messages between an account known to be used by Buchanan and other unidentified co-conspirators discussing dividing up the proceeds of SIM swapping.”

U.S. prosecutors allege that records obtained from Discord showed the same U.K. Internet address was used to operate a Discord account that specified a cryptocurrency wallet when asking another user to send funds. The complaint says the publicly available transaction history for that payment address shows approximately 391 bitcoin was transferred in and out of this address between October 2022 and
February 2023; 391 bitcoin is presently worth more than $26 million.

In November 2024, federal prosecutors in Los Angeles unsealed criminal charges against Buchanan and four other alleged Scattered Spider members, including Ahmed Elbadawy, 23, of College Station, Texas; Joel Evans, 25, of Jacksonville, North Carolina; Evans Osiebo, 20, of Dallas; and Noah Urban, 20, of Palm Coast, Florida. KrebsOnSecurity reported last year that another suspected Scattered Spider member — a 17-year-old from the United Kingdom — was arrested as part of a joint investigation with the FBI into the MGM hack.

Mr. Buchanan’s court-appointed attorney did not respond to a request for comment. The accused faces charges of wire fraud conspiracy, conspiracy to obtain information by computer for private financial gain, and aggravated identity theft. Convictions on the latter charge carry a minimum sentence of two years in prison.

Documents from the U.S. District Court for the Central District of California indicate Buchanan is being held without bail pending trial. A preliminary hearing in the case is slated for May 6.

China-based purveyors of SMS phishing kits are enjoying remarkable success converting phished payment card data into mobile wallets from Apple and Google. Until recently, the so-called “Smishing Triad” mainly impersonated toll road operators and shipping companies. But experts say these groups are now directly targeting customers of international financial institutions, while dramatically expanding their cybercrime infrastructure and support staff.

If you own a mobile device, the chances are excellent that at some point in the past two years you’ve received at least one instant message that warns of a delinquent toll road fee, or a wayward package from the U.S. Postal Service (USPS). Those who click the promoted link are brought to a website that spoofs the USPS or a local toll road operator and asks for payment card information.

The site will then complain that the visitor’s bank needs to “verify” the transaction by sending a one-time code via SMS. In reality, the bank is sending that code to the mobile number on file for their customer because the fraudsters have just attempted to enroll that victim’s card details into a mobile wallet.

If the visitor supplies that one-time code, their payment card is then added to a new mobile wallet on an Apple or Google device that is physically controlled by the phishers. The phishing gangs typically load multiple stolen cards to digital wallets on a single Apple or Android device, and then sell those phones in bulk to scammers who use them for fraudulent e-commerce and tap-to-pay transactions.

The moniker “Smishing Triad” comes from Resecurity, which was among the first to report in August 2023 on the emergence of three distinct mobile phishing groups based in China that appeared to share some infrastructure and innovative phishing techniques. But it is a bit of a misnomer because the phishing lures blasted out by these groups are not SMS or text messages in the conventional sense.

Rather, they are sent via iMessage to Apple device users, and via RCS on Google Android devices. Thus, the missives bypass the mobile phone networks entirely and enjoy near 100 percent delivery rate (at least until Apple and Google suspend the spammy accounts).

In a report published on March 24, the Swiss threat intelligence firm Prodaft detailed the rapid pace of innovation coming from the Smishing Triad, which it characterizes as a loosely federated group of Chinese phishing-as-a-service operators with names like Darcula, Lighthouse, and the Xinxin Group.

Prodaft said they’re seeing a significant shift in the underground economy, particularly among Chinese-speaking threat actors who have historically operated in the shadows compared to their Russian-speaking counterparts.

“Chinese-speaking actors are introducing innovative and cost-effective systems, enabling them to target larger user bases with sophisticated services,” Prodaft wrote. “Their approach marks a new era in underground business practices, emphasizing scalability and efficiency in cybercriminal operations.”

A new report from researchers at the security firm SilentPush finds the Smishing Triad members have expanded into selling mobile phishing kits targeting customers of global financial institutions like CitiGroup, MasterCard, PayPal, Stripe, and Visa, as well as banks in Canada, Latin America, Australia and the broader Asia-Pacific region.

SilentPush found the Smishing Triad now spoofs recognizable brands in a variety of industry verticals across at least 121 countries and a vast number of industries, including the postal, logistics, telecommunications, transportation, finance, retail and public sectors.

According to SilentPush, the domains used by the Smishing Triad are rotated frequently, with approximately 25,000 phishing domains active during any 8-day period and a majority of them sitting at two Chinese hosting companies: Tencent (AS132203) and Alibaba (AS45102).

“With nearly two-thirds of all countries in the world targeted by [the] Smishing Triad, it’s safe to say they are essentially targeting every country with modern infrastructure outside of Iran, North Korea, and Russia,” SilentPush wrote. “Our team has observed some potential targeting in Russia (such as domains that mentioned their country codes), but nothing definitive enough to indicate Russia is a persistent target. Interestingly, even though these are Chinese threat actors, we have seen instances of targeting aimed at Macau and Hong Kong, both special administrative regions of China.”

SilentPush’s Zach Edwards said his team found a vulnerability that exposed data from one of the Smishing Triad’s phishing pages, which revealed the number of visits each site received each day across thousands of phishing domains that were active at the time. Based on that data, SilentPush estimates those phishing pages received well more than a million visits within a 20-day time span.

The report notes the Smishing Triad boasts it has “300+ front desk staff worldwide” involved in one of their more popular phishing kits — Lighthouse — staff that is mainly used to support various aspects of the group’s fraud and cash-out schemes.

The Smishing Triad members maintain their own Chinese-language sales channels on Telegram, which frequently offer videos and photos of their staff hard at work. Some of those images include massive walls of phones used to send phishing messages, with human operators seated directly in front of them ready to receive any time-sensitive one-time codes.

As noted in February’s story How Phished Data Turns Into Apple and Google Wallets, one of those cash-out schemes involves an Android app called Z-NFC, which can relay a valid NFC transaction from one of these compromised digital wallets to anywhere in the world. For a $500 month subscription, the customer can wave their phone at any payment terminal that accepts Apple or Google pay, and the app will relay an NFC transaction over the Internet from a stolen wallet on a phone in China.

Chinese nationals were recently busted trying to use these NFC apps to buy high-end electronics in Singapore. And in the United States, authorities in California and Tennessee arrested Chinese nationals accused of using NFC apps to fraudulently purchase gift cards from retailers.

The Prodaft researchers said they were able to find a previously undocumented backend management panel for Lucid, a smishing-as-a-service operation tied to the XinXin Group. The panel included victim figures that suggest the smishing campaigns maintain an average success rate of approximately five percent, with some domains receiving over 500 visits per week.

“In one observed instance, a single phishing website captured 30 credit card records from 550 victim interactions over a 7-day period,” Prodaft wrote.

Prodaft’s report details how the Smishing Triad has achieved such success in sending their spam messages. For example, one phishing vendor appears to send out messages using dozens of Android device emulators running in parallel on a single machine.

According to Prodaft, the threat actors first acquire phone numbers through various means including data breaches, open-source intelligence, or purchased lists from underground markets. They then exploit technical gaps in sender ID validation within both messaging platforms.

“For iMessage, this involves creating temporary Apple IDs with impersonated display names, while RCS exploitation leverages carrier implementation inconsistencies in sender verification,” Prodaft wrote. “Message delivery occurs through automated platforms using VoIP numbers or compromised credentials, often deployed in precisely timed multi-wave campaigns to maximize effectiveness.

In addition, the phishing links embedded in these messages use time-limited single-use URLs that expire or redirect based on device fingerprinting to evade security analysis, they found.

“The economics strongly favor the attackers, as neither RCS nor iMessage messages incur per-message costs like traditional SMS, enabling high-volume campaigns at minimal operational expense,” Prodaft continued. “The overlap in templates, target pools, and tactics among these platforms underscores a unified threat landscape, with Chinese-speaking actors driving innovation in the underground economy. Their ability to scale operations globally and evasion techniques pose significant challenges to cybersecurity defenses.”

Ford Merrill works in security research at SecAlliance, a CSIS Security Group company. Merrill said he’s observed at least one video of a Windows binary that wraps a Chrome executable and can be used to load in target phone numbers and blast messages via RCS, iMessage, Amazon, Instagram, Facebook, and WhatsApp.

“The evidence we’ve observed suggests the ability for a single device to send approximately 100 messages per second,” Merrill said. “We also believe that there is capability to source country specific SIM cards in volume that allow them to register different online accounts that require validation with specific country codes, and even make those SIM cards available to the physical devices long-term so that services that rely on checks of the validity of the phone number or SIM card presence on a mobile network are thwarted.”

Experts say this fast-growing wave of card fraud persists because far too many financial institutions still default to sending one-time codes via SMS for validating card enrollment in mobile wallets from Apple or Google. KrebsOnSecurity interviewed multiple security executives at non-U.S. financial institutions who spoke on condition of anonymity because they were not authorized to speak to the press. Those banks have since done away with SMS-based one-time codes and are now requiring customers to log in to the bank’s mobile app before they can link their card to a digital wallet.
