Fraudsters are flooding Discord and other social media platforms with ads for hundreds of polished online gaming and wagering websites that lure people with free credits and eventually abscond with any cryptocurrency funds deposited by players. Here’s a closer look at the social engineering tactics and remarkable traits of this sprawling network of more than 1,200 scam sites.

The scam begins with deceptive ads posted on social media that claim the wagering sites are working in partnership with popular social media personalities, such as Mr. Beast, who recently launched a gaming business called Beast Games. The ads invariably state that by using a supplied “promo code,” interested players can claim a $2,500 credit on the advertised gaming website.

The gaming sites all require users to create a free account to claim their $2,500 credit, which they can use to play any number of extremely polished video games that ask users to bet on each action. At the scam website gamblerbeast[.]com, for example, visitors can pick from dozens of games like B-Ball Blitz, in which you play a basketball pro who is taking shots from the free throw line against a single opponent, and you bet on your ability to sink each shot.

The financial part of this scam begins when users try to cash out any “winnings.” At that point, the gaming site will reject the request and prompt the user to make a “verification deposit” of cryptocurrency — typically around $100 — before any money can be distributed. Those who deposit cryptocurrency funds are soon asked for additional payments.

However, any “winnings” displayed by these gaming sites are a complete fantasy, and players who deposit cryptocurrency funds will never see that money again. Compounding the problem, victims likely will soon be peppered with come-ons from “recovery experts” who peddle dubious claims on social media networks about being able to retrieve funds lost to such scams.

KrebsOnSecurity first learned about this network of phony betting sites from a Discord user who asked to be identified only by their screen name: “Thereallo” is a 17-year-old developer who operates multiple Discord servers and said they began digging deeper after users started complaining of being inundated with misleading spam messages promoting the sites.

“We were being spammed relentlessly by these scam posts from compromised or purchased [Discord] accounts,” Thereallo said. “I got frustrated with just banning and deleting, so I started to investigate the infrastructure behind the scam messages. This is not a one-off site, it’s a scalable criminal enterprise with a clear playbook, technical fingerprints, and financial infrastructure.”

After comparing the code on the gaming sites promoted via spam messages, Thereallo found they all invoked the same API key for an online chatbot that appears to be in limited use or else is custom-made. Indeed, a scan for that API key at the threat hunting platform Silent Push reveals at least 1,270 recently-registered and active domains whose names all invoke some type of gaming or wagering theme.

The “verification deposit” stage of the scam requires the user to deposit cryptocurrency in order to withdraw their “winnings.”

Thereallo said the operators of this scam empire appear to generate a unique Bitcoin wallet for each gaming domain they deploy.

“This is a decoy wallet,” Thereallo explained. “Once the victim deposits funds, they are never able to withdraw any money. Any attempts to contact the ‘Live Support’ are handled by a combination of AI and human operators who eventually block the user. The chat system is self-hosted, making it difficult to report to third-party service providers.”

Thereallo discovered another feature common to all of these scam gambling sites [hereafter referred to simply as “scambling” sites]: If you register at one of them and then very quickly try to register at a sister property of theirs from the same Internet address and device, the registration request is denied at the second site.

“I registered on one site, then hopped to another to register again,” Thereallo said. Instead, the second site returned an error stating that a new account couldn’t be created for another 10 minutes.

The scam gaming site spinora dot cc shares the same chatbot API as more than 1,200 similar fake gaming sites.

“They’re tracking my VPN IP across their entire network,” Thereallo explained. “My password manager also proved it. It tried to use my dummy email on a site I had never visited, and the site told me the account already existed. So it’s definitely one entity running a single platform with 1,200+ different domain names as front-ends. This explains how their support works, a central pool of agents handling all the sites. It also explains why they’re so strict about not giving out wallet addresses; it’s a network-wide policy.”

In many ways, these scambling sites borrow from the playbook of “pig butchering” schemes, a rampant and far more elaborate crime in which people are gradually lured by flirtatious strangers online into investing in fraudulent cryptocurrency trading platforms.

Pig butchering scams are typically powered by people in Asia who have been kidnapped and threatened with physical harm or worse unless they sit in a cubicle and scam Westerners on the Internet all day. In contrast, these scambling sites tend to steal far less money from individual victims, but their cookie-cutter nature and automated support components may enable their operators to extract payments from a large number of people in far less time, and with considerably less risk and up-front investment.

Silent Push’s Zach Edwards said the proprietors of this scambling empire are spending big money to make the sites look and feel like some fancy new type of casino.

“That’s a very odd type of pig butchering network and not like what we typically see, with much lower investments in the sites and lures,” Edwards said.

Here is a list of all domains that Silent Push found were using the scambling network’s chat API.

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.

Mr. Lizhi’s LinkedIn account was suspended sometime in the last 24 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.

One of multiple GitHub profiles used by Liu “Steve” Lizhi, who uses the nickname XXL4 (a moniker listed in the Treasury sanctions for Mr. Lizhi).

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.

All of the follower accounts for the XXL4 GitHub account appear to be Mr. Lizhi’s, and have been suspended by GitHub, but their code is still accessible.

“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.

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.

A graphic from the FBI explaining how Funnull generated a slew of new domains on a regular basis and mapped them to Internet addresses on U.S. cloud providers.

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.”

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.

Many successful phishing attacks result in a financial loss or malware infection. But falling for some phishing scams, like those currently targeting Russians searching online for organizations that are fighting the Kremlin war machine, can cost you your freedom or your life.

The real website of the Ukrainian paramilitary group “Freedom of Russia” legion. The text has been machine-translated from Russian.

Researchers at the security firm Silent Push mapped a network of several dozen phishing domains that spoof the recruitment websites of Ukrainian paramilitary groups, as well as Ukrainian government intelligence sites.

The website legiohliberty[.]army features a carbon copy of the homepage for the Freedom of Russia Legion (a.k.a. “Free Russia Legion”), a three-year-old Ukraine-based paramilitary unit made up of Russian citizens who oppose Vladimir Putin and his invasion of Ukraine.

The phony version of that website copies the legitimate site — legionliberty[.]army — providing an interactive Google Form where interested applicants can share their contact and personal details. The form asks visitors to provide their name, gender, age, email address and/or Telegram handle, country, citizenship, experience in the armed forces; political views; motivations for joining; and any bad habits.

“Participation in such anti-war actions is considered illegal in the Russian Federation, and participating citizens are regularly charged and arrested,” Silent Push wrote in a report released today. “All observed campaigns had similar traits and shared a common objective: collecting personal information from site-visiting victims. Our team believes it is likely that this campaign is the work of either Russian Intelligence Services or a threat actor with similarly aligned motives.”

Silent Push’s Zach Edwards said the fake Legion Liberty site shared multiple connections with rusvolcorps[.]net. That domain mimics the recruitment page for a Ukrainian far-right paramilitary group called the Russian Volunteer Corps (rusvolcorps[.]com), and uses a similar Google Forms page to collect information from would-be members.

Other domains Silent Push connected to the phishing scheme include: ciagov[.]icu, which mirrors the content on the official website of the U.S. Central Intelligence Agency; and hochuzhitlife[.]com, which spoofs the Ministry of Defense of Ukraine & General Directorate of Intelligence (whose actual domain is hochuzhit[.]com).

According to Edwards, there are no signs that these phishing sites are being advertised via email. Rather, it appears those responsible are promoting them by manipulating the search engine results shown when someone searches for one of these anti-Putin organizations.

In August 2024, security researcher Artem Tamoian posted on Twitter/X about how he received startlingly different results when he searched for “Freedom of Russia legion” in Russia’s largest domestic search engine Yandex versus Google.com. The top result returned by Google was the legion’s actual website, while the first result on Yandex was a phishing page targeting the group.

“I think at least some of them are surely promoted via search,” Tamoian said of the phishing domains. “My first thread on that accuses Yandex, but apart from Yandex those websites are consistently ranked above legitimate in DuckDuckGo and Bing. Initially, I didn’t realize the scale of it. They keep appearing to this day.”

Tamoian, a native Russian who left the country in 2019, is the founder of the cyber investigation platform malfors.com. He recently discovered two other sites impersonating the Ukrainian paramilitary groups — legionliberty[.]world and rusvolcorps[.]ru — and reported both to Cloudflare. When Cloudflare responded by blocking the sites with a phishing warning, the real Internet address of these sites was exposed as belonging to a known “bulletproof hosting” network called Stark Industries Solutions Ltd.

Stark Industries Solutions appeared two weeks before Russia invaded Ukraine in February 2022, materializing out of nowhere with hundreds of thousands of Internet addresses in its stable — many of them originally assigned to Russian government organizations. In May 2024, KrebsOnSecurity published a deep dive on Stark, which has repeatedly been used to host infrastructure for distributed denial-of-service (DDoS) attacks, phishing, malware and disinformation campaigns from Russian intelligence agencies and pro-Kremlin hacker groups.

In March 2023, Russia’s Supreme Court designated the Freedom of Russia legion as a terrorist organization, meaning that Russians caught communicating with the group could face between 10 and 20 years in prison.

Tamoian said those searching online for information about these paramilitary groups have become easy prey for Russian security services.

“I started looking into those phishing websites, because I kept stumbling upon news that someone gets arrested for trying to join [the] Ukrainian Army or for trying to help them,” Tamoian told KrebsOnSecurity. “I have also seen reports [of] FSB contacting people impersonating Ukrainian officers, as well as using fake Telegram bots, so I thought fake websites might be an option as well.”

Search results showing news articles about people in Russia being sentenced to lengthy prison terms for attempting to aid Ukrainian paramilitary groups.

Tamoian said reports surface regularly in Russia about people being arrested for trying carry out an action requested by a “Ukrainian recruiter,” with the courts unfailingly imposing harsh sentences regardless of the defendant’s age.

“This keeps happening regularly, but usually there are no details about how exactly the person gets caught,” he said. “All cases related to state treason [and] terrorism are classified, so there are barely any details.”

Tamoian said while he has no direct evidence linking any of the reported arrests and convictions to these phishing sites, he is certain the sites are part of a larger campaign by the Russian government.

“Considering that they keep them alive and keep spawning more, I assume it might be an efficient thing,” he said. “They are on top of DuckDuckGo and Yandex, so it unfortunately works.”
