Justice Department seizes infrastructure used by cyber scam and criminal marketplace

23 June 2026 at 14:34

The Justice Department on Tuesday said it has seized infrastructure tied to what officials called one of the world’s most prolific criminal marketplaces, used to commit cyber scams and other crimes.

The seized cloud computing account hosted backend infrastructure used by subsidiaries of the Huione Group, a Cambodia-based corporate conglomerate.

At the same time, the Treasury Department announced fresh sanctions and more against Huione and affiliated companies. The administration actions Tuesday add to disruption efforts from last fall against pieces of the same network.

The Trump administration has placed an emphasis on combating transnational cybercrime and other kinds of scams and fraud.

The seized cloud computing account was used to operate Huione Guarantee, also known as Haowang Guarantee, according to Tuesday’s DOJ announcement.

“The Huione Group used this cloud computing account as part of a technological backbone that allowed billions in fraud proceeds to be transferred, moved, and concealed — much of it stolen through Southeast Asian scam centers,” said Tysen Duva, assistant attorney general of the Justice Department’s Criminal Division. “Seizures of these marketplaces is critical in the fight against fraud that affects so many Americans, and to stop avenues for criminal proceeds to be laundered.”

U.S. officials allege that Huione Guarantee operated Telegram channels with discussions about illicit goods and services, including the sale of stolen credit card and sensitive personal information, malware-enabled thefts, human trafficking schemes and the laundering of money from romance and investment scams. Huione Guarantee also allegedly offered escrow services for criminals such as money launderers for cryptocurrency.

Treasury took two steps Tuesday to build on its move in October to sever Huione Group from the U.S. financial system. One was to tack H-Pay Service onto its rule for Huione Group as a successor entity. And it slapped nine people and 26 entities linked to Prince Group with sanctions.

“Huione Group served as a critical node for laundering proceeds of cyber heists and virtual currency investment scams and was used by the Prince Group to transfer and consolidate scam-derived assets,” Treasury’s announcement states.

Also last October, the Justice Department said it seized bitcoin valued at $15 billion from the chairman of the Prince Group, Chen Zhi, and indicted him over alleged cryptocurrency crimes and other schemes. 

An alleged key figure in Chen’s criminal network has been arrested in Cambodia and extradited to China.

Algerian man charged with running two cybercrime marketplaces

By: Greg Otto
23 June 2026 at 10:36

An Algerian man known online as “SPOX” was extradited from Spain and charged with running a black-market cybercrime operation that prosecutors say defrauded thousands of victims and funneled roughly $900,000 through a cryptocurrency account over a three-year period.

Abdellah Belmili, 26, made his initial appearance Monday in the U.S. District Court for the Western District of New York in Buffalo. He faces a single count of conspiracy to commit bank fraud, which carries a maximum sentence of 30 years in prison. 

He was extradited from Spain earlier this month.

Federal investigators say Belmili allegedly created and administered at least two illicit online marketplaces, market0day.com and spoxy.us, that operated similarly to commercial e-commerce platforms. The marketplaces sold financial credentials, phishing kits, compromised email server access, and other tools used to carry out fraud. All transactions on the sites were conducted in Bitcoin.

According to court documents, the FBI became aware of the marketplaces in September 2020 through a confidential source. The site’s administrator was already known to investigators as a prolific creator of phishing kits targeting major U.S. financial institutions.

In 2020, undercover FBI agents used the marketplace to buy a phishing kit designed to replicate JPMorgan Chase’s login page and capture victims’ personal information. Agents also purchased access to a compromised email server. A third item — access to a website control panel — was paid for but never delivered, prompting customer complaints on Belmili’s Telegram channel.

Shortly after those complaints surfaced, Belmili announced he was closing market0day.com and redirecting customers to a new site, spoxy.us, which he described as a “new store for bulk sms,” which typically refers to mass phishing via text message. 

The new site used the same template, color scheme, and navigation structure as its predecessor and was registered using the stolen identity of a 77-year-old Texas resident.

Investigators identified Belmili through a combination of open-source research, search warrants, and records obtained from technology and financial companies. Early versions of his phishing kit code contained his full name, “Dila Belmili,” embedded in the source alongside his Telegram handle and a link to the marketplaces. Facebook accounts linked to the alias “spox_coder” listed “Dila Belmili (spox)” as the display name, and customers had posted complaints about phishing kit purchases directly on his profile.

Records obtained from Google showed that Belmili used his personal email account to search for financial institution logos, hacking tools, and methods for generating fake identities and credit card numbers. The same account received approximately 1,400 emails containing victims’ stolen personal information from active phishing kits targeting American Express, Bank of America, Cash App, JP Morgan Chase, PayPal, and Wells Fargo.

Investigators also found that Belmili had built hidden backdoors into phishing kits he sold to other criminals, allowing him to continue harvesting victim data even after the kits changed hands.

Records from cryptocurrency exchange Binance showed approximately $900,000 deposited into an account registered to Belmili between Jan. 2020 and Jan. 2023. Of that amount, roughly $760,000 was transferred to other accounts or converted into other forms of cryptocurrency, while approximately $41,000 was withdrawn from ATMs. 

In total, investigators identified approximately 595 distinct phishing kits created by Belmili. Analysis of victim data exported to Telegram pages and email accounts linked to the operation identified roughly 5,600 victims in the United States and internationally.

“This defendant thought that he could get away with defrauding thousands of victims out of hundreds of thousands of dollars by using fake names and hiding behind a keyboard to steal bank account and credit card numbers,” said U.S. Attorney Michael DiGiacomo in a release. “This arrest makes clear that, regardless of where you operate, our law enforcement partners will find you – and when they do, you will face the full consequences of your actions.”

DHS Secretary Markwayne Mullin pinpoints optimal CISA staffing levels

3 June 2026 at 15:56

Department of Homeland Security Secretary Markwayne Mullin told Congress Wednesday that the Cybersecurity and Infrastructure Security Agency would ideally have 2,800 personnel, up from approximately 2,200 now and down from 3,400 before the second Trump administration began.

President Donald Trump has pushed to dramatically reduce personnel numbers at the agency, something that has drawn criticism from both Democrats and Republicans on the Hill. Trump has proposed hundreds of millions more in cuts for fiscal 2027.

House Homeland Security Committee Chairman Andrew Garbarino, R-N.Y., asked Mullin at a hearing Wednesday about further proposed CISA budget cuts, saying he was “concerned” about personnel numbers and funding for education programs and whether the fiscal 2027 blueprint would “negatively impact those efforts.”

Mullin said DHS funding lapses have made the department rethink CISA, although the deep CISA personnel reductions predate the recent spate of government shutdowns. 

“We had to readjust the way we’re looking at CISA and better lean on public partnerships,” he said. The agency can work well with 2,800 people “If we can actually have the partnerships we need with states and be able to use the grants, the monies that [we] saved with CISA to be able to invest with local and state municipalities. … We’re not going to fail on the mission we have in front of us.”

CISA personnel figures are in a constant state of flux. The CISA staff figure of 2,200 Mullin gave is down even from December. In March, acting director Nick Andersen said CISA was looking to hire 300 people.

There’s been no proposal from the Trump administration to-date to take funds formerly allocated to CISA and shift them to state governments for cybersecurity. State officials have said CISA budget cuts have made their jobs harder, and most experts have said the Trump administration’s approach to shift cyber responsibilities to states is badly misguided.

Congress has yet to permanently reauthorize the State and Local Cybersecurity Grant Program that expired last year before it got a temporary extension and is due to expire again in September.

CISA has gone without a Senate-confirmed director for the entirety of the second Trump administration. Mullin said “we’ve got a person soon to be nominated that will be running CISA that has the ability to recruit and focus on the authorities we have.”

Mullin said CISA has “unique” authorities that haven’t “been completely utilized.” 

“We want CISA to be the leader in cybersecurity,” he said. “They should be and they will be.”

A House Appropriations subcommittee is set to consider a DHS funding bill Friday.

Hackers Used Meta’s AI Support Bot to Seize Instagram Accounts

1 June 2026 at 13:32

The Instagram accounts for the Obama White House and the Chief Master Sergeant of the U.S. Space Force were briefly defaced with pro-Iranian images and messages over the weekend, after instructions began circulating on Telegram showing how to trick Meta’s “AI support assistant” bot into resetting account passwords.

A screenshot from a video released on Telegram claiming to show how Meta’s AI customer support bot could be tricked into resetting a target’s password.

On May 31, word began to spread on several Telegram instant message channels that Meta’s AI bot would happily add an email address to an existing account as part of the bot’s standard password reset flow.

A video released on Telegram by pro-Iran hackers claimed to document a remarkably simple exploit that appears to have involved using a VPN connection with an IP address that is in or near the target’s usual hometown, requesting a password reset for the account, and then choosing to chat with Meta’s AI support assistant. From there, the video shows the attacker told the bot to link the account in question to a new email address, after which the bot dutifully sent that address a one-time code that allowed a password reset.

The Telegram account that posted the video also linked to screenshots of pro-Iran images, videos and messages that defaced the hacked Instagram accounts, saying hackers had used the exploit to hijack a number of valuable (read: short) Instagram account names that allegedly have a resale value of more than a half million dollars.

Meta has not responded to requests for comment on the video’s claims, but Meta’s Andy Stone said on Twitter/X that the issue had been resolved and that they were securing impacted accounts. The security blog thecybersecguru.com reports that Meta pushed an emergency patch over the weekend, and clarified that no back end database was breached.

“Instagram has notoriously poor human support infrastructure,” Cybersecguru wrote. “Recovering a locked account – especially a high-value one can take weeks of back-and-forth with an automated ticketing system. Meta’s solution was to deploy a conversational AI layer to handle common recovery workflows: relinking a lost email address, triggering a password reset, verifying account ownership. The assistant, presumably, was supposed to reduce friction for legitimate users stuck in account-access hell.”

Ian Goldin, a threat researcher at Lumen’s Black Lotus Labs, said we’re entering unchartered security territory as more large online platforms start allowing AI chatbots to handle sensitive account recovery requests. Just like human customer support employees can be social engineered into providing unauthorized access to someone’s account, AI bots are equally eager to help and vulnerable to persuasion and trickery, he said.

“AI chatbots create interesting new attack surface, and we’re likely going to see a lot more of these kinds of attacks,” Goldin said.

Securing your various online accounts means taking full advantage of the most secure form of multi-factor authentication (MFA) offered (such as a passkey or security key). In this case, even using the least robust form of MFA that Instagram offers — a one-time code sent via SMS — likely would have blocked the exploit: The hackers who released the video on Telegram said their exploit failed to work against any accounts that had MFA enabled.

Iranian hackers, Handala, claim to compromise FBI Director Kash Patel’s personal data

27 March 2026 at 13:28

Iranian hackers claimed Friday to have compromised the personal data of FBI Director Kash Patel, and the bureau confirmed that it knew of the targeting of Patel’s personal email.

The government-connected hacking group, Handala, previously claimed credit for hacking medical device maker Stryker, a boast that threat researchers considered credible.

“All personal and confidential email of Kash Patel, including emails, conversations, documents, and even classified files, is now available for public download,” Handala — also known as Handala Hack — said.

The group said it did so in response to the FBI seizing its domains and the U.S. government offering a $10 million reward for information on members of the group.

The FBI noted that Handala frequently targets government officials, and challenged elements of Handala’s claims, such as that it had brought the FBI’s systems “to its knees,” rather than Patel’s own email.

“The FBI is aware of malicious actors targeting Director Patel’s personal email information, and we have taken all necessary steps to mitigate potential risks associated with this activity,” the FBI said in response to questions from CyberScoop. “The information in question is historical in nature and involves no government information.”

The activist group Distributed Denial of Secrets published what it said was Patel’s email cache.

The FBI pointed to the State Department’s reward program seeking information on members of Handala.

“Consistent with President Trump’s Cyber Strategy for America, the FBI will continue to pursue the actors responsible, support victims, and share actionable intelligence in defense of networks,” it said. “We encourage anyone who experiences a cyber breach, or has information related to malicious cyber activity, to contact their local FBI field office.”

FBI: Iranian hackers targeting opponents with Telegram malware

23 March 2026 at 14:35

Iranian government-connected groups are deploying malware via the Telegram messaging app, taking aim at dissidents and other opponents of Tehran around the world, the FBI said in an alert Friday.

The FBI said attackers linked to the Ministry of Intelligence and Security are behind the campaign, which stretches back to 2023. The bureau is escalating the alert now, though, because of the conflict between Iran and a U.S.-Israel alliance, it states.

“The observed victim profile included Iranian dissidents, journalists opposed to Iran, members of organizations with beliefs counter to Government of Iran narratives, and other individuals Iran perceives as a threat to the Iranian government, However, the malware could be used to target any individual of interest to Iran.” the alert reads. “This malware resulted in intelligence collection, data leaks, and reputational harm against the targeted parties.” 

Handala — an Iranian pro-Palestinian group that claimed credit for the hack on medical device maker Stryker this month — used information it gathered from hacking dissidents to carry out a hack-and-leak campaign in 2025, the FBI assesses. (Stryker sent a notice to the Securities and Exchange Commission Monday that provides an update on the incident.)

While U.S. officials say they haven’t seen any major increase in cyberattacks out of Iran since the conflict began, experts have noted it could be weeks before patterns emerge.

Telegram is a popular communications channel in Iran. Iranian hackers frequent Telegram to discuss planned attacks. On the other hand, the Islamic Revolutionary Guard Corps has also issued warnings to its populace that they could face prosecution if they’re members of Telegram-based opposition channels, IranWire reported last week.

The FBI said from the malware samples it examined, the scheme begins with hackers masquerading as apps like Pictory, KeePass and Telegram. The hackers configure command and control using a Telegram bot.

To gain initial access, the hackers seek to manipulate victims by posing as someone they know or as tech support for a social media platform. They then trick the victims into accepting a file transfer, which then launches the malware.

“Based on multiple observations, stage 1 of the malware appeared to be tailored to the victim’s pattern of life to increase likelihood of victim downloading the malware, which indicates the Iranian cyber actors likely performed target reconnaissance prior to engaging with the victim,” the FBI said.

The FBI alert is the latest in a series of government warnings about attackers using messaging apps to carry out their objectives.

Telegram spokesperson Remi Vaughn said in an emailed response: “Bad actors can and do use any available channel to control malware, including other messengers, email or even direct web connections. While there is nothing unique about the use of Telegram to control software, moderators routinely remove any accounts found to be involved with malware.”

DDoS Botnet Aisuru Blankets US ISPs in Record DDoS

10 October 2025 at 12:10

The world’s largest and most disruptive botnet is now drawing a majority of its firepower from compromised Internet-of-Things (IoT) devices hosted on U.S. Internet providers like AT&T, Comcast and Verizon, new evidence suggests. Experts say the heavy concentration of infected devices at U.S. providers is complicating efforts to limit collateral damage from the botnet’s attacks, which shattered previous records this week with a brief traffic flood that clocked in at nearly 30 trillion bits of data per second.

Since its debut more than a year ago, the Aisuru botnet has steadily outcompeted virtually all other IoT-based botnets in the wild, with recent attacks siphoning Internet bandwidth from an estimated 300,000 compromised hosts worldwide.

The hacked systems that get subsumed into the botnet are mostly consumer-grade routers, security cameras, digital video recorders and other devices operating with insecure and outdated firmware, and/or factory-default settings. Aisuru’s owners are continuously scanning the Internet for these vulnerable devices and enslaving them for use in distributed denial-of-service (DDoS) attacks that can overwhelm targeted servers with crippling amounts of junk traffic.

As Aisuru’s size has mushroomed, so has its punch. In May 2025, KrebsOnSecurity was hit with a near-record 6.35 terabits per second (Tbps) attack from Aisuru, which was then the largest assault that Google’s DDoS protection service Project Shield had ever mitigated. Days later, Aisuru shattered that record with a data blast in excess of 11 Tbps.

By late September, Aisuru was publicly flexing DDoS capabilities topping 22 Tbps. Then on October 6, its operators heaved a whopping 29.6 terabits of junk data packets each second at a targeted host. Hardly anyone noticed because it appears to have been a brief test or demonstration of Aisuru’s capabilities: The traffic flood lasted less only a few seconds and was pointed at an Internet server that was specifically designed to measure large-scale DDoS attacks.

Aisuru’s overlords aren’t just showing off. Their botnet is being blamed for a series of increasingly massive and disruptive attacks. Although recent assaults from Aisuru have targeted mostly ISPs that serve online gaming communities like Minecraft, those digital sieges often result in widespread collateral Internet disruption.

For the past several weeks, ISPs hosting some of the Internet’s top gaming destinations have been hit with a relentless volley of gargantuan attacks that experts say are well beyond the DDoS mitigation capabilities of most organizations connected to the Internet today.

Steven Ferguson is principal security engineer at Global Secure Layer (GSL), an ISP in Brisbane, Australia. GSL hosts TCPShield, which offers free or low-cost DDoS protection to more than 50,000 Minecraft servers worldwide. Ferguson told KrebsOnSecurity that on October 8, TCPShield was walloped with a blitz from Aisuru that flooded its network with more than 15 terabits of junk data per second.

Ferguson said that after the attack subsided, TCPShield was told by its upstream provider OVH that they were no longer welcome as a customer.

“This was causing serious congestion on their Miami external ports for several weeks, shown publicly via their weather map,” he said, explaining that TCPShield is now solely protected by GSL.

Traces from the recent spate of crippling Aisuru attacks on gaming servers can be still seen at the website blockgametracker.gg, which indexes the uptime and downtime of the top Minecraft hosts. In the following example from a series of data deluges on the evening of September 28, we can see an Aisuru botnet campaign briefly knocked TCPShield offline.

An Aisuru botnet attack on TCPShield (AS64199) on Sept. 28  can be seen in the giant downward spike in the middle of this uptime graphic. Image: grafana.blockgametracker.gg.

Paging through the same uptime graphs for other network operators listed shows almost all of them suffered brief but repeated outages around the same time. Here is the same uptime tracking for Minecraft servers on the network provider Cosmic (AS30456), and it shows multiple large dips that correspond to game server outages caused by Aisuru.

BOTNETS R US

Ferguson said he’s been tracking Aisuru for about three months, and recently he noticed the botnet’s composition shifted heavily toward infected systems at ISPs in the United States. Ferguson shared logs from an attack on October 8 that indexed traffic by the total volume sent through each network provider, and the logs showed that 11 of the top 20 traffic sources were U.S. based ISPs.

AT&T customers were by far the biggest U.S. contributors to that attack, followed by botted systems on Charter Communications, Comcast, T-Mobile and Verizon, Ferguson found. He said the volume of data packets per second coming from infected IoT hosts on these ISPs is often so high that it has started to affect the quality of service that ISPs are able to provide to adjacent (non-botted) customers.

“The impact extends beyond victim networks,” Ferguson said. “For instance we have seen 500 gigabits of traffic via Comcast’s network alone. This amount of egress leaving their network, especially being so US-East concentrated, will result in congestion towards other services or content trying to be reached while an attack is ongoing.”

Roland Dobbins is principal engineer at Netscout. Dobbins said Ferguson is spot on, noting that while most ISPs have effective mitigations in place to handle large incoming DDoS attacks, many are far less prepared to manage the inevitable service degradation caused by large numbers of their customers suddenly using some or all available bandwidth to attack others.

“The outbound and cross-bound DDoS attacks can be just as disruptive as the inbound stuff,” Dobbin said. “We’re now in a situation where ISPs are routinely seeing terabit-per-second plus outbound attacks from their networks that can cause operational problems.”

“The crying need for effective and universal outbound DDoS attack suppression is something that is really being highlighted by these recent attacks,” Dobbins continued. “A lot of network operators are learning that lesson now, and there’s going to be a period ahead where there’s some scrambling and potential disruption going on.”

KrebsOnSecurity sought comment from the ISPs named in Ferguson’s report. Charter Communications pointed to a recent blog post on protecting its network, stating that Charter actively monitors for both inbound and outbound attacks, and that it takes proactive action wherever possible.

“In addition to our own extensive network security, we also aim to reduce the risk of customer connected devices contributing to attacks through our Advanced WiFi solution that includes Security Shield, and we make Security Suite available to our Internet customers,” Charter wrote in an emailed response to questions. “With the ever-growing number of devices connecting to networks, we encourage customers to purchase trusted devices with secure development and manufacturing practices, use anti-virus and security tools on their connected devices, and regularly download security patches.”

A spokesperson for Comcast responded, “Currently our network is not experiencing impacts and we are able to handle the traffic.”

9 YEARS OF MIRAI

Aisuru is built on the bones of malicious code that was leaked in 2016 by the original creators of the Mirai IoT botnet. Like Aisuru, Mirai quickly outcompeted all other DDoS botnets in its heyday, and obliterated previous DDoS attack records with a 620 gigabit-per-second siege that sidelined this website for nearly four days in 2016.

The Mirai botmasters likewise used their crime machine to attack mostly Minecraft servers, but with the goal of forcing Minecraft server owners to purchase a DDoS protection service that they controlled. In addition, they rented out slices of the Mirai botnet to paying customers, some of whom used it to mask the sources of other types of cybercrime, such as click fraud.

Dobbins said Aisuru’s owners also appear to be renting out their botnet as a distributed proxy network that cybercriminal customers anywhere in the world can use to anonymize their malicious traffic and make it appear to be coming from regular residential users in the U.S.

“The people who operate this botnet are also selling (it as) residential proxies,” he said. “And that’s being used to reflect application layer attacks through the proxies on the bots as well.”

The Aisuru botnet harkens back to its predecessor Mirai in another intriguing way. One of its owners is using the Telegram handle “9gigsofram,” which corresponds to the nickname used by the co-owner of a Minecraft server protection service called Proxypipe that was heavily targeted in 2016 by the original Mirai botmasters.

Robert Coelho co-ran Proxypipe back then along with his business partner Erik “9gigsofram” Buckingham, and has spent the past nine years fine-tuning various DDoS mitigation companies that cater to Minecraft server operators and other gaming enthusiasts. Coelho said he has no idea why one of Aisuru’s botmasters chose Buckingham’s nickname, but added that it might say something about how long this person has been involved in the DDoS-for-hire industry.

“The Aisuru attacks on the gaming networks these past seven day have been absolutely huge, and you can see tons of providers going down multiple times a day,” Coelho said.

Coelho said the 15 Tbps attack this week against TCPShield was likely only a portion of the total attack volume hurled by Aisuru at the time, because much of it would have been shoved through networks that simply couldn’t process that volume of traffic all at once. Such outsized attacks, he said, are becoming increasingly difficult and expensive to mitigate.

“It’s definitely at the point now where you need to be spending at least a million dollars a month just to have the network capacity to be able to deal with these attacks,” he said.

RAPID SPREAD

Aisuru has long been rumored to use multiple zero-day vulnerabilities in IoT devices to aid its rapid growth over the past year. XLab, the Chinese security company that was the first to profile Aisuru’s rise in 2024, warned last month that one of the Aisuru botmasters had compromised the firmware distribution website for Totolink, a maker of low-cost routers and other networking gear.

“Multiple sources indicate the group allegedly compromised a router firmware update server in April and distributed malicious scripts to expand the botnet,” XLab wrote on September 15. “The node count is currently reported to be around 300,000.”

Aisuru’s operators received an unexpected boost to their crime machine in August when the U.S. Department Justice charged the alleged proprietor of Rapper Bot, a DDoS-for-hire botnet that competed directly with Aisuru for control over the global pool of vulnerable IoT systems.

Once Rapper Bot was dismantled, Aisuru’s curators moved quickly to commandeer vulnerable IoT devices that were suddenly set adrift by the government’s takedown, Dobbins said.

“Folks were arrested and Rapper Bot control servers were seized and that’s great, but unfortunately the botnet’s attack assets were then pieced out by the remaining botnets,” he said. “The problem is, even if those infected IoT devices are rebooted and cleaned up, they will still get re-compromised by something else generally within minutes of being plugged back in.”

A screenshot shared by XLabs showing the Aisuru botmasters recently celebrating a record-breaking 7.7 Tbps DDoS. The user at the top has adopted the name “Ethan J. Foltz” in a mocking tribute to the alleged Rapper Bot operator who was arrested and charged in August 2025.

BOTMASTERS AT LARGE

XLab’s September blog post cited multiple unnamed sources saying Aisuru is operated by three cybercriminals: “Snow,” who’s responsible for botnet development; “Tom,” tasked with finding new vulnerabilities; and “Forky,” responsible for botnet sales.

KrebsOnSecurity interviewed Forky in our May 2025 story about the record 6.3 Tbps attack from Aisuru. That story identified Forky as a 21-year-old man from Sao Paulo, Brazil who has been extremely active in the DDoS-for-hire scene since at least 2022. The FBI has seized Forky’s DDoS-for-hire domains several times over the years.

Like the original Mirai botmasters, Forky also operates a DDoS mitigation service called 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.

In our previous interview, Forky acknowledged being involved in the development and marketing of Aisuru, but denied participating in attacks launched by the botnet.

Reached for comment earlier this month, Forky continued to maintain his innocence, claiming that he also is still trying to figure out who the current Aisuru botnet operators are in real life (Forky said the same thing in our May interview).

But after a week of promising juicy details, Forky came up empty-handed once again. Suspecting that Forky was merely being coy, I asked him how someone so connected to the DDoS-for-hire world could still be mystified on this point, and suggested that his inability or unwillingness to blame anyone else for Aisuru would not exactly help his case.

At this, Forky verbally bristled at being pressed for more details, and abruptly terminated our interview.

“I’m not here to be threatened with ignorance because you are stressed,” Forky replied. “They’re blaming me for those new attacks. Pretty much the whole world (is) due to your blog.”
