A cyberattack that shut down two of the top casinos in Las Vegas last year quickly became one of the most riveting security stories of 2023: It was the first known case of native English-speaking hackers in the United States and Britain teaming up with ransomware gangs based in Russia. But that made-for-Hollywood narrative has eclipsed a far more hideous trend: Many of these young, Western cybercriminals are also members of fast-growing online groups that exist solely to bully, stalk, harass and extort vulnerable teens into physically harming themselves and others.

In September 2023, a Russian ransomware group known as ALPHV/Black Cat claimed credit for an intrusion at the MGM Resorts hotel chain that quickly brought MGM’s casinos in Las Vegas to a standstill. While MGM was still trying to evict the intruders from its systems, an individual who claimed to have firsthand knowledge of the hack contacted multiple media outlets to offer interviews about how it all went down.

One account of the hack came from a 17-year-old in the United Kingdom, who told reporters the intrusion began when one of the English-speaking hackers phoned a tech support person at MGM and tricked them into resetting the password for an employee account.

The security firm CrowdStrike dubbed the group “Scattered Spider,” a recognition that the MGM hackers came from different hacker cliques scattered across an ocean of Telegram and Discord servers dedicated to financially-oriented cybercrime.

Collectively, this archipelago of crime-focused chat communities is known as “The Com,” and it functions as a kind of distributed cybercriminal social network that facilitates instant collaboration.

But mostly, The Com is a place where cybercriminals go to boast about their exploits and standing within the community, or to knock others down a peg or two. Top Com members are constantly sniping over who pulled off the most impressive heists, or who has accumulated the biggest pile of stolen virtual currencies.

And as often as they extort victim companies for financial gain, members of The Com are constantly trying to wrest stolen money from their cybercriminal rivals — often in ways that spill over into physical violence in the real world.

CrowdStrike would go on to produce and sell Scattered Spider action figures, and it featured a life-sized Scattered Spider sculpture at this year’s RSA Security Conference in San Francisco.

But marketing security products and services based on specific cybercriminal groups can be tricky, particularly if it turns out that robbing and extorting victims is by no means the most abhorrent activity those groups engage in on a daily basis.

KrebsOnSecurity examined the Telegram user ID number of the account that offered media interviews about the MGM hack — which corresponds to the screen name “@Holy” — and found the same account was used across a number of cybercrime channels that are entirely focused on extorting young people into harming themselves or others, and recording the harm on video.

In one post on a Telegram channel dedicated to youth extortion, this same user can be seen asking if anyone knows the current Telegram handles for several core members of 764, an extremist group known for victimizing children through coordinated online campaigns of extortion, doxing, swatting and harassment.

HOLY NAZI

Holy was known to possess multiple prized Telegram usernames, including @bomb, @halo, and @cute, as well as one of the highest-priced Telegram usernames ever put up for sale: @nazi. A source close to the investigation said @Holy also was a moderator on “Harm Nation,” an offshoot of 764.

People affiliated with harm groups like 764 will often recruit new members by lurking on gaming platforms, social media sites and mobile applications that are popular with young people, including Discord, Minecraft, Roblox, Steam, Telegram, and Twitch.

“This type of offence usually starts with a direct message through gaming platforms and can move to more private chatrooms on other virtual platforms, typically one with video enabled features, where the conversation quickly becomes sexualized or violent,” warns a recent alert from the Royal Canadian Mounted Police (RCMP) about the rise of sextortion groups on social media channels.

“One of the tactics being used by these actors is sextortion, however, they are not using it to extract money or for sexual gratification,” the RCMP continued. “Instead they use it to further manipulate and control victims to produce more harmful and violent content as part of their ideological objectives and radicalization pathway.”

The 764 network is among the most populated harm communities, but there are plenty more. Some of the largest such known groups include CVLT, Court, Kaskar, Leak Society, 7997, 8884, 2992, 6996, 555, Slit Town, 545, 404, NMK, 303, and H3ll.

In March, a consortium of reporters from Wired, Der Spiegel, Recorder and The Washington Post examined millions of messages across more than 50 Discord and Telegram chat groups.

“The abuse perpetrated by members of com groups is extreme,” Wired’s Ali Winston wrote. “They have coerced children into sexual abuse or self-harm, causing them to deeply lacerate their bodies to carve ‘cutsigns’ of an abuser’s online alias into their skin.” The story continues:

“Victims have flushed their heads in toilets, attacked their siblings, killed their pets, and in some extreme instances, attempted or died by suicide. Court records from the United States and European nations reveal participants in this network have also been accused of robberies, in-person sexual abuse of minors, kidnapping, weapons violations, swatting, and murder.”

“Some members of the network extort children for sexual pleasure, some for power and control. Some do it merely for the kick that comes from manipulation. Others sell the explicit CSAM content produced by extortion on the dark web.”

KrebsOnSecurity has learned Holy’s real name is Owen David Flowers, and that he is the previously unnamed 17-year-old who was arrested in July 2024 by the U.K.’s West Midlands Police as part of a joint investigation with the FBI into the MGM hack.

Early in their cybercriminal career (as a 15-year-old), @Holy went by the handle “Vsphere,” and was a proud member of the LAPSUS$ cybercrime group. Throughout 2022, LAPSUS$ would hack and social engineer their way into some of the world’s biggest technology companies, including EA Games, Microsoft, NVIDIA, Okta, Samsung, and T-Mobile.

JUDISCHE/WAIFU

Another timely example of the overlap between harm communities and top members of The Com can be found in a group of criminals who recently stole obscene amounts of customer records from users of the cloud data provider Snowflake.

At the end of 2023, malicious hackers figured out that many major companies have uploaded massive amounts of valuable and sensitive customer data to Snowflake servers, all the while protecting those Snowflake accounts with little more than a username and password (no multi-factor authentication required). The group then searched darknet markets for stolen Snowflake account credentials, and began raiding the data storage repositories used by some of the world’s largest corporations.

Among those that had data exposed in Snowflake was AT&T, which disclosed in July that cybercriminals had stolen personal information and phone and text message records for roughly 110 million people — nearly all its customers.

A report on the extortion group from the incident response firm Mandiant notes that Snowflake victim companies were privately approached by the hackers, who demanded a ransom in exchange for a promise not to sell or leak the stolen data. All told, more than 160 organizations were extorted, including TicketMaster, Lending Tree, Advance Auto Parts and Neiman Marcus.

On May 2, 2024, a user by the name “Judische” claimed on the fraud-focused Telegram channel Star Chat that they had hacked Santander Bank, one of the first known Snowflake victims. Judische would repeat that claim in Star Chat on May 13 — the day before Santander publicly disclosed a data breach — and would periodically blurt out the names of other Snowflake victims before their data even went up for sale on the cybercrime forums.

A careful review of Judische’s account history and postings on Telegram shows this user is more widely known under the nickname “Waifu,” an early moniker that corresponds to one of the more accomplished SIM-swappers in The Com over the years.

In a SIM-swapping attack, the fraudsters will phish or purchase credentials for mobile phone company employees, and use those credentials to redirect a target’s mobile calls and text messages to a device the attackers control.

Several channels on Telegram maintain a frequently updated leaderboard of the 100 richest SIM-swappers, as well as the hacker handles associated with specific cybercrime groups (Waifu is ranked #24). That leaderboard has long included Waifu on a roster of hackers for a group that called itself “Beige.”

Beige members were implicated in two stories published here in 2020. The first was an August 2020 piece called Voice Phishers Targeting Corporate VPNs, which warned that the COVID-19 epidemic had brought a wave of voice phishing or “vishing” attacks that targeted work-from-home employees via their mobile devices, and tricked many of those people into giving up credentials needed to access their employer’s network remotely.

Beige group members also have claimed credit for a breach at the domain registrar GoDaddy. In November 2020, intruders thought to be associated with the Beige Group tricked a GoDaddy employee into installing malicious software, and with that access they were able to redirect the web and email traffic for multiple cryptocurrency trading platforms.

The Telegram channels that Judische and his related accounts frequented over the years show this user divides their time between posting in SIM-swapping and cybercrime cashout channels, and harassing and stalking others in harm communities like Leak Society and Court.

Mandiant has attributed the Snowflake compromises to a group it calls “UNC5537,” with members based in North America and Turkey. KrebsOnSecurity has learned Judische is a 26-year-old software engineer in Ontario, Canada.

Sources close to the investigation into the Snowflake incident tell KrebsOnSecurity the UNC5537 member in Turkey is John Erin Binns, an elusive American man indicted by the U.S. Department of Justice (DOJ) for a 2021 breach at T-Mobile that exposed the personal information of at least 76.6 million customers.

Binns is currently in custody in a Turkish prison and fighting his extradition. Meanwhile, he has been suing almost every federal agency and agent that contributed investigative resources to his case.

In June 2024, a Mandiant employee told Bloomberg that UNC5537 members have made death threats against cybersecurity experts investigating the hackers, and that in one case the group used artificial intelligence to create fake nude photos of a researcher to harass them.

ViLE

In June 2024, two American men pleaded guilty to hacking into a U.S. Drug Enforcement Agency (DEA) online portal that tapped into 16 different federal law enforcement databases.  Sagar “Weep” Singh, a 20-year-old from Rhode Island, and Nicholas “Convict” Ceraolo, 25, of Queens, NY, were both active in SIM-swapping communities.

Singh and Ceraolo hacked into a number of foreign police department email accounts, and used them to make phony “emergency data requests” to social media platforms seeking account information about specific users they were stalking. According to the government, in each case the men impersonating the foreign police departments told those platforms the request was urgent because the account holders had been trading in child pornography or engaging in child extortion.

Eventually, the two men formed part of a group of cybercriminals known to its members as “ViLE,” who specialize in obtaining personal information about third-party victims, which they then used to harass, threaten or extort the victims, a practice known as “doxing.”

The U.S. government says Singh and Ceraolo worked closely with a third man — referenced in the indictment as co-conspirator #1 or “CC-1” — to administer a doxing forum where victims could pay to have their personal information removed.

The government doesn’t name CC-1 or the doxing forum, but CC-1’s hacker handle is “Kayte” (a.k.a. “KT“) which corresponds to the nickname of a 23-year-old man who lives with his parents in Coffs Harbor, Australia. For several years (with a brief interruption), KT has been the administrator of a truly vile doxing community known as the Doxbin.

People whose names and personal information appear on the Doxbin can quickly find themselves the target of extended harassment campaigns, account hacking, SIM-swapping and even swatting — which involves falsely reporting a violent incident at a target’s address to trick local police into responding with potentially deadly force.

A handful of Com members targeted by federal authorities have gone so far as to perpetrate swatting, doxing, and other harassment against the same federal agents who are trying to unravel their alleged crimes. This has led some investigators working cases involving the Com to begin redacting their names from affidavits and indictments filed in federal court.

In January 2024, KrebsOnSecurity broke the news that prosecutors in Florida had charged a 19-year-old alleged Scattered Spider member named Noah Michael Urban with wire fraud and identity theft. That story recounted how Urban’s alleged hacker identities “King Bob” and “Sosa” inhabited a world in which rival cryptocurrency theft rings frequently settled disputes through so-called “violence-as-a-service” offerings — hiring strangers online to perpetrate firebombings, beatings and kidnappings against their rivals.

Urban’s indictment is currently sealed. But a copy of the document obtained by KrebsOnSecurity shows the name of the federal agent who testified to it has been blacked out.

The final page of Noah Michael Urban’s indictment shows the investigating agent redacted their name from charging documents.

HACKING RINGS, STALKING VICTIMS

In June 2022, this blog told the story of two men charged with hacking into the Ring home security cameras of a dozen random people and then methodically swatting each of them. Adding insult to injury, the men used the compromised security cameras to record live footage of local police swarming those homes.

McCarty, in a mugshot.

James Thomas Andrew McCarty, Charlotte, N.C., and Kya Christian Nelson, of Racine, Wisc., conspired to hack into Yahoo email accounts belonging to victims in the United States. The two would check how many of those Yahoo accounts were associated with Ring accounts, and then target people who used the same password for both accounts.

The Telegram and Discord aliases allegedly used by McCarty — “Aspertaine” and “Couch,” among others — correspond to an identity that was active in certain channels dedicated to SIM-swapping.

What KrebsOnSecurity didn’t report at the time is that both ChumLul and Aspertaine were active members of CVLT, wherein those identities clearly participated in harassing and exploiting young teens online.

In June 2024, McCarty was sentenced to seven years in prison after pleading guilty to making hoax calls that elicited police SWAT responses. Nelson also pleaded guilty and received a seven-year prison sentence.

POMPOMPURIN

In March 2023, U.S. federal agents in New York announced they’d arrested “Pompompurin,” the alleged administrator of Breachforums, an English-language cybercrime forum where hacked corporate databases frequently appear for sale. In cases where the victim organization isn’t extorted in advance by hackers, being listed on Breachforums has often been the way many victims first learned of an intrusion.

Pompompurin had been a nemesis to the FBI for several years. In November 2021, KrebsOnSecurity broke the news that thousands of fake emails about a cybercrime investigation were blasted out from the FBI’s email systems and Internet addresses.

Pompompurin took credit for that stunt, and said he was able to send the FBI email blast by exploiting a flaw in an FBI portal designed to share information with state and local law enforcement authorities. The FBI later acknowledged that a software misconfiguration allowed someone to send the fake emails.

In December, 2022, KrebsOnSecurity detailed how hackers active on BreachForums had infiltrated the FBI’s InfraGard program, a vetted network designed to build cyber and physical threat information sharing partnerships with experts in the private sector. The hackers impersonated the CEO of a major financial company, applied for InfraGard membership in the CEO’s name, and were granted admission to the community.

The feds named Pompompurin as 21-year-old Peeksill resident Conor Brian Fitzpatrick, who was originally charged with one count of conspiracy to solicit individuals to sell unauthorized access devices (stolen usernames and passwords). But after FBI agents raided and searched the home where Fitzpatrick lived with his parents, prosecutors tacked on charges for possession of child pornography.

DOMESTIC TERRORISM?

Recent actions by the DOJ indicate the government is well aware of the significant overlap between leading members of The Com and harm communities. But the government also is growing more sensitive to the criticism that it can often take months or years to gather enough evidence to criminally charge some of these suspects, during which time the perpetrators can abuse and recruit countless new victims.

Late last year, however, the DOJ signaled a new tactic in pursuing leaders of harm communities like 764: Charging them with domestic terrorism.

In December 2023, the government charged (PDF) a Hawaiian man with possessing and sharing sexually explicit videos and images of prepubescent children being abused. Prosecutors allege Kalana Limkin, 18, of Hilo, Hawaii, admitted he was an associate of CVLT and 764, and that he was the founder of a splinter harm group called Cultist. Limkin’s Telegram profile shows he also was active on the harm community Slit Town.

The relevant citation from Limkin’s complaint reads:

“Members of the group ‘764’ have conspired and continue to conspire in both online and in-person venues to engage in violent actions in furtherance of a Racially Motivated Violent Extremist ideology, wholly or in part through activities that violate federal criminal law meeting the statutory definition of Domestic Terrorism, defined in Title 18, United States Code, § 2331.”

Experts say charging harm groups under anti-terrorism statutes potentially gives the government access to more expedient investigative powers than it would normally have in a run-of-the-mill criminal hacking case.

“What it ultimately gets you is additional tools you can use in the investigation, possibly warrants and things like that,” said Mark Rasch, a former U.S. federal cybercrime prosecutor and now general counsel for the New York-based cybersecurity firm Unit 221B. “It can also get you additional remedies at the end of the case, like greater sanctions, more jail time, fines and forfeiture.”

But Rasch said this tactic can backfire on prosecutors who overplay their hand and go after someone who ends up challenging the charges in court.

“If you’re going to charge a hacker or pedophile with a crime like terrorism, that’s going to make it harder to get a conviction,” Rasch said. “It adds to the prosecutorial burden and increases the likelihood of getting an acquittal.”

Rasch said it’s unclear where it is appropriate to draw the line in the use of terrorism statutes to disrupt harm groups online, noting that there certainly are circumstances where individuals can commit violations of domestic anti-terrorism statutes through their Internet activity alone.

“The Internet is a platform like any other, where virtually any kind of crime that can be committed in the real world can also be committed online,” he said. “That doesn’t mean all misuse of computers fits within the statutory definition of terrorism.”

The RCMP’s warning on sexual extortion of minors over the Internet lists a number of potential warning signs that teens may exhibit if they become immeshed in these harm groups. The FBI urges anyone who believes their child or someone they know is being exploited to contact their local FBI field office, call 1-800-CALL-FBI, or report it online at tips.fbi.gov.

Three men in the United Kingdom have pleaded guilty to operating otp[.]agency, a once popular online service that helped attackers intercept the one-time passcodes (OTPs) that many websites require as a second authentication factor in addition to passwords.

Launched in November 2019, OTP Agency was a service for intercepting one-time passwords needed to log in to various websites. Scammers who had already stolen someone’s bank account credentials could enter the target’s phone number and name, and the service would initiate an automated phone call to the target that warned them about unauthorized activity on their account.

The call would prompt the target to enter a one-time passcode generated by their phone’s mobile app, and the code was then relayed to the scammer’s user panel at the OTP Agency website.

A statement published Aug. 30 by the U.K.’s National Crime Agency (NCA) said three men pleaded guilty to running OTP Agency: Callum Picari, 22, from Hornchurch, Essex; Vijayasidhurshan Vijayanathan, 21, from Aylesbury, Buckinghamshire; and Aza Siddeeque, 19, from Milton Keynes, Buckinghamshire.

KrebsOnSecurity profiled OTP Agency in a February 2021 story about arrests tied to another phishing-related service based in the U.K. Someone claiming to represent OTP Agency then posted several comments on the piece, wherein they claimed the story was libelous and that they were a legitimate anti-fraud service. However, the service’s Telegram channel clearly showed its proprietors had built OTP Agency with one purpose in mind: To help their customers take over online accounts.

Within hours of that publication, OTP Agency shuttered its website and announced it was closing up shop and purging its user database. The NCA said the February 2021 story prompted a panicked message exchange between Picari and Vijayanathan:

Picari said: bro we are in big trouble… U will get me bagged… Bro delete the chat

Vijayanathan: Are you sure

Picari: So much evidence in there

Vijayanathan: Are you 100% sure

Picari: It’s so incriminating…Take a look and search ‘fraud’…Just think of all the evidence…that we cba to find…in the OTP chat…they will find

Vijayanathan: Exactly so if we just shut EVERYTHING down

Picari: They went to our first ever msg…We look incriminating…if we shut down…I say delete the chat…Our chat is Fraud 100%

Vijayanathan : Everyone with a brain will tell you stop it here and move on

Picari: Just because we close it doesn’t mean we didn’t do it…But deleting our chat…Will f*^k their investigations…There’s nothing fraudulent on the site

Despite deleting its Telegram channel, OTP Agency evidently found it difficult to walk away from its customers (and/or the money). Instead of shutting down as Vijayanathan wisely advised, just a few days later OTP Agency was communicating with customers on a new Telegram channel, offering a new login page and assuring existing customers that their usernames, passwords and balances would remain the same.

OTP Agency, immediately after their initial shutdown, telling customers their existing logins will still work.

But that revival would be short-lived. The NCA said the site was taken offline less than a month later when the trio were arrested. NCA investigators said more than 12,500 people were targeted by OTP Agency users during the 18 month the service was active.

Picari was the owner, developer and main beneficiary of the service, and his personal information and ownership of OTP Agency was revealed in February 2020 in a “dox” posted to the now-defunct English-language cybercrime forum Raidforums. The NCA said it began investigating the service in June 2020.

The OTP Agency operators who pleaded guilty to running the service; Aza Siddeeque, Callum Picari, and Vijayasidhurshan Vijayanathan.

OTP Agency might be gone, but several other similar OTP interception services are still in operation and accepting new customers, including a long-running service KrebsOnSecurity profiled in September 2021 called SMSRanger. More on SMSRanger in an upcoming post.

Text messages, emails and phone calls warning recipients about potential fraud are some of the most common scam lures. If someone (or something) calls saying they’re from your bank, or asks you to provide any personal or financial information, do not respond.  Just hang up, full stop.

If the call has you worried about the security and integrity of your account, check the account status online, or call your financial institution — ideally using a phone number that came from the bank’s Web site or from the back of your payment card.

A partial selfie posted by Puchmade Dev to his Twitter account. Yes, that is a functioning handheld card skimming device, encrusted in diamonds. Underneath that are more medallions, including a diamond-studded bitcoin and payment card.

In January, KrebsOnSecurity wrote about rapper Punchmade Dev, whose music videos sing the praises of a cybercrime lifestyle. That story showed how Punchmade’s social media profiles promoted Punchmade-themed online stores selling bank account and payment card data. The subject of that piece, a 22-year-old Kentucky man, is now brazenly suing his financial institution after it blocked a $75,000 wire transfer and froze his account, citing an active law enforcement investigation.

With memorable hits such as “Internet Swiping” and “Million Dollar Criminal” earning millions of views, Punchmade Dev has leveraged his considerable following to peddle tutorials on how to commit financial crimes online. But until recently, there wasn’t much to support a conclusion that Punchmade was actually doing the cybercrime things he promotes in his songs.

That changed earlier this year when KrebsOnSecurity showed how Punchmade’s social media handles were promoting Punchmade e-commerce shops online that sold access to Cashapp and PayPal accounts with balances, software for printing checks, as well as personal and financial data on Americans.

Punchmade Dev’s previous online shop (now defunct). His Telegram channel has more than 75,000 followers.

The January story traced Punchmade’s various online properties to a 22-year-old Devon Turner from Lexington, Ky. Reached via his profile on X/Twitter, Punchmade Dev said they were not affiliated with the lawsuit filed by Turner [Punchmade’s X account provided this denial even though it has still not responded to requests for comment from the first story about him in January]. Meanwhile, Mr. Turner has declined multiple requests to comment for this story.

On June 26, Turner filed a pro se lawsuit against PNC Bank, alleging “unlawful discriminatory and tortuous action” after he was denied a wire transfer in the amount of $75,000. PNC Bank did not respond to a request for comment.

Turner’s complaint states that a follow-up call to his bank revealed the account had been closed due to “suspicious activity,” and that he was no longer welcome to patronize PNC Bank.

“The Plaintiff is a very successful African-American business owner, who has generated millions of dollars with his businesses, has hired 30 plus people to work for his businesses,” Turner wrote.

As reported in January, among Turner’s businesses is a Lexington entity called OBN Group LLC (assumed name Punchmade LLC). Business incorporation documents from the Kentucky Secretary of State show he also ran a record label called DevTakeFlightBeats Inc.

Turner’s lawsuit alleges that bank staff made disparaging remarks about him, suggesting the account was canceled because it would be unusual for a person like him to have that kind of money.

A snippet from Turner’s lawsuit vs. PNC.

Incredibly, Turner acknowledges that PNC told him his account was flagged for attention from law enforcement officials.

“The PNC Bank customer service representative also explained that there was a note on the account that law enforcement would be contacted at some point in time,” the lawsuit reads.

“The Plaintiff, who was not worried at all about law enforcement being involved because nothing illegal occurred, informed the PNC Bank representative that this was one big mistake and asked him what his options were,” the complaint states.

Turner’s lawsuit said PNC told him they would put a note on his account allowing him to withdraw the funds from any branch, but that when he visited a PNC branch and asked to withdraw the entire amount in his account — $500,000 — PNC refused, saying the money had been seized.

“Ultimately, PNC bank not only refused his request to release his funds but informed him that his funds would be seized indefinitely as [sic] PNC Bank,” Turner lawsuit recounts.

The Punchmade shops selling financial data that were profiled in the January story are long gone, but Punchmade’s Instagram account now promotes punchmade[.]cc, which behaves and looks the same as his older shop.

Punchmade’s current shop, which DomainTools says was registered to a Lexington, Ky. phone number used by accounts under the name of Devon Turner at multiple online retailers.

The breach tracking service Constella Intelligence finds the email address associated with Turner’s enterprise OBN Group LLC — obndevpayments@gmail.com — was used by a Devon Turner from Lexington to purchase software online. That record includes the Lexington, Ky. mobile phone number 859-963-6243, which Constella also finds was used to register accounts for Devon Turner at the retailer Neiman Marcus, and at the home decor and fashion site poshmark.com.

A search on this phone number at DomainTools shows it is associated with two domain names since 2021. The first is the aforementioned punchmade[.]cc. The other is foreverpunchmade[.]com, which is registered to a Devon Turner in Lexington, Ky. A copy of this site at archive.org indicates it once sold Punchmade Dev-branded t-shirts and other merchandise.

Mr. Turner included his contact information at the bottom of his lawsuit. What phone number did he leave? Would you believe 859-963-6243?

The closing section of Mr. Turner’s complaint includes a phone number that was used to register a popular online fraud shop named after Punchmade.

Is Punchmade Dev a big-time cybercriminal enabler, as his public personna would have us believe? Or is he some two-bit nitwit who has spent so much on custom medallions that he can’t afford a lawyer? It’s hard to tell.

But he definitively has a broad reach: His Instagram account has ~860k followers, and his Telegram channel has more than 75,000 subscribers, all no doubt seeking that sweet “C@sh App sauce,” which apparently has something to do with moving cryptocurrencies through Cash App in a way that financially rewards people able and willing to open up new accounts.

It’s incredibly ironic that Punchmade sells tutorials on how to have great “opsec,” a reference to “operational security,” which in the cybercriminal context means the ability to successfully separate one’s cybercriminal identity from one’s real-life identity: This guy can’t even register a domain name anonymously.

A copy of Turner’s complaint is available here (PDF).

Twenty-four prisoners were freed today in an international prisoner swap between Russia and Western countries. Among the eight Russians repatriated were five convicted cybercriminals. In return, Russia has reportedly released 16 prisoners, including Wall Street Journal reporter Evan Gershkovich and ex-U.S. Marine Paul Whelan.

Among the more notable Russian hackers released in the prisoner swap is Roman Seleznev, 40, who was sentenced in 2017 to 27 years in prison for racketeering convictions tied to a lengthy career in stealing and selling payment card data. Seleznev earned this then-record sentence by operating some of the underground’s most bustling marketplaces for stolen card data.

Once known by the hacker handles “Track2,” “Bulba” and “nCux,” Seleznev is the son of Valery Seleznev, a prominent member of the Russian parliament who is considered an ally of Vladimir Putin. U.S. prosecutors showed that for years Vinnik stayed a step ahead of the law by tapping into contacts at the Russian FSB, the successor agency to the Soviet KGB, and by periodically changing hacker handles.

But in 2014 Seleznev was captured by U.S. Secret Service agents, who had zeroed in on Seleznev’s posh vacation spot in The Maldives. At the time, the South Asian island country was a popular destination for Eastern Europe-based cybercriminals, who viewed it as beyond the reach of U.S. law enforcement.

In addition to receiving a record prison sentence, Seleznev was ordered to pay more than $50 million in restitution to his victims. That loss amount equaled the total losses inflicted by Seleznev’s various carding stores, and other thefts attributed to members of the hacking forum carder[.]su, a bustling cybercrime community of which Seleznev was a leading organizer.

Also released in the prisoner swap was Vladislav Klyushin, a 42-year-old Muscovite sentenced in September 2023 to nine years in prison for what U.S. prosecutors called a “$93 million hack-to-trade conspiracy.” Klyushin and his crew hacked into companies and used information stolen in those intrusions to make illegal stock trades.

Klyushin likewise was arrested while vacationing abroad: The Associated Press reported that Klyushin was captured in Switzerland after arriving on a private jet, and just before he and his party were about to board a helicopter to whisk them to a nearby ski resort.

Klyushin is the owner of M-13, a Russian technology company that contracts with the Russian government. According to prosecutors, M-13 offered penetration testing and “advanced persistent threat (APT) emulation.” As part of his guilty plea, Klyushin was also ordered to forfeit $34 million, and to pay restitution in an amount that was to be determined.

The U.S. government says four of Klyushin’s alleged co-conspirators remain at large, including Ivan Ermakov, who was among 12 Russians charged in 2018 with hacking into key Democratic Party email accounts.

Russia also welcomed home one of its most accomplished money launderers. Alexander Vinnik, 44, who was one of the operators of BTC-e, a large cryptocurrency exchange that helped launder crime proceeds tied to various ransomware groups.

In 2017, U.S. authorities seized BTC-e, charging Vinnik with operating an international money laundering scheme that included some 850,000 bitcoins stolen from cryptocurrency exchange Mt. Gox. In May 2024, Vinnik pleaded guilty to laundering more than $9 billion.

Vladimir Dunaev, 40, was one of the masterminds behind the Trickbot trojan, a crimeware-as-a-service platform that for many years was used by Russian cybercrime groups to install ransomware and siphon data from victims. Duanev was sentenced in January 2024 to five years and four months in prison.

The fifth convicted Russian sent back home this week is Maxim Marchenko, 52, who pleaded guilty in February 2024 to illicitly procuring large quantities of U.S.-made microelectronics on behalf of Russian clients in support of the war on Ukraine.

Marchenko admitted setting up a number of shell companies based in Hong Kong that were used to acquire the technology products that have military-grade applications, such as rifle scopes, night vision goggles and thermal optics.

Among the Americans freed by Russia were Wall Street Journal reporter Evan Gershkovich, 32, who has spent the last 16 months in a Russian prison on spying charges. Also released was Alsu Kurmasheva, 47, a Russian American editor for Radio Free Europe/Radio Liberty who was arrested last year; and Paul Whelan, 54, a former U.S. Marine arrested in 2018 and accused of spying.

The New York Times reports several others freed by Russia were German nationals, including German Moyzhes, a lawyer who was helping Russians obtain residence permits in Germany and other E.U. countries. The Times says Slovenia, Norway and Poland released four people accused of being Russian spies.

Reuters reports that Germany released Vadim Krasikov, an FSB colonel serving a life sentence there for murdering an exiled Chechen-Georgian dissident in a Berlin park.

The Russia-based cybercrime group dubbed “Fin7,” known for phishing and malware attacks that have cost victim organizations an estimated $3 billion in losses since 2013, was declared dead last year by U.S. authorities. But experts say Fin7 has roared back to life in 2024 — setting up thousands of websites mimicking a range of media and technology companies — with the help of Stark Industries Solutions, a sprawling hosting provider that is a persistent source of cyberattacks against enemies of Russia.

In May 2023, the U.S. attorney for Washington state declared “Fin7 is an entity no more,” after prosecutors secured convictions and prison sentences against three men found to be high-level Fin7 hackers or managers. This was a bold declaration against a group that the U.S. Department of Justice described as a criminal enterprise with more than 70 people organized into distinct business units and teams.

The first signs of Fin7’s revival came in April 2024, when Blackberry wrote about an intrusion at a large automotive firm that began with malware served by a typosquatting attack targeting people searching for a popular free network scanning tool.

Now, researchers at security firm Silent Push say they have devised a way to map out Fin7’s rapidly regrowing cybercrime infrastructure, which includes more than 4,000 hosts that employ a range of exploits, from typosquatting and booby-trapped ads to malicious browser extensions and spearphishing domains.

Silent Push said it found Fin7 domains targeting or spoofing brands including American Express, Affinity Energy, Airtable, Alliant, Android Developer, Asana, Bitwarden, Bloomberg, Cisco (Webex), CNN, Costco, Dropbox, Grammarly, Google, Goto.com, Harvard, Lexis Nexis, Meta, Microsoft 365, Midjourney, Netflix, Paycor, Quickbooks, Quicken, Reuters, Regions Bank Onepass, RuPay, SAP (Ariba), Trezor, Twitter/X, Wall Street Journal, Westlaw, and Zoom, among others.

Zach Edwards, senior threat analyst at Silent Push, said many of the Fin7 domains are innocuous-looking websites for generic businesses that sometimes include text from default website templates (the content on these sites often has nothing to do with the entity’s stated business or mission).

Edwards said Fin7 does this to “age” the domains and to give them a positive or at least benign reputation before they’re eventually converted for use in hosting brand-specific phishing pages.

“It took them six to nine months to ramp up, but ever since January of this year they have been humming, building a giant phishing infrastructure and aging domains,” Edwards said of the cybercrime group.

In typosquatting attacks, Fin7 registers domains that are similar to those for popular free software tools. Those look-alike domains are then advertised on Google so that sponsored links to them show up prominently in search results, which is usually above the legitimate source of the software in question.

A malicious site spoofing FreeCAD showed up prominently as a sponsored result in Google search results earlier this year.

According to Silent Push, the software currently being targeted by Fin7 includes 7-zip, PuTTY, ProtectedPDFViewer, AIMP, Notepad++, Advanced IP Scanner, AnyDesk, pgAdmin, AutoDesk, Bitwarden, Rest Proxy, Python, Sublime Text, and Node.js.

In May 2024, security firm eSentire warned that Fin7 was spotted using sponsored Google ads to serve pop-ups prompting people to download phony browser extensions that install malware. Malwarebytes blogged about a similar campaign in April, but did not attribute the activity to any particular group.

Edwards said Silent Push discovered the new Fin7 domains after a hearing from an organization that was targeted by Fin7 in years past and suspected the group was once again active. Searching for hosts that matched Fin7’s known profile revealed just one active site. But Edwards said that one site pointed to many other Fin7 properties at Stark Industries Solutions, a large hosting provider that materialized just two weeks before Russia invaded Ukraine.

As KrebsOnSecurity wrote in May, Stark Industries Solutions is being used as a staging ground for wave after wave of cyberattacks against Ukraine that have been tied to Russian military and intelligence agencies.

“FIN7 rents a large amount of dedicated IP on Stark Industries,” Edwards said. “Our analysts have discovered numerous Stark Industries IPs that are solely dedicated to hosting FIN7 infrastructure.”

Fin7 once famously operated behind fake cybersecurity companies — with names like Combi Security and Bastion Secure — which they used for hiring security experts to aid in ransomware attacks. One of the new Fin7 domains identified by Silent Push is cybercloudsec[.]com, which promises to “grow your business with our IT, cyber security and cloud solutions.”

The fake Fin7 security firm Cybercloudsec.

Like other phishing groups, Fin7 seizes on current events, and at the moment it is targeting tourists visiting France for the Summer Olympics later this month. Among the new Fin7 domains Silent Push found are several sites phishing people seeking tickets at the Louvre.

“We believe this research makes it clear that Fin7 is back and scaling up quickly,” Edwards said. “It’s our hope that the law enforcement community takes notice of this and puts Fin7 back on their radar for additional enforcement actions, and that quite a few of our competitors will be able to take this pool and expand into all or a good chunk of their infrastructure.”

Most accomplished cybercriminals go out of their way to separate their real names from their hacker handles. But among certain old-school Russian hackers it is not uncommon to find major players who have done little to prevent people from figuring out who they are in real life. A case study in this phenomenon is “x999xx,” the nickname chosen by a venerated Russian hacker who specializes in providing the initial network access to various ransomware groups.

x999xx is a well-known “access broker” who frequently sells access to hacked corporate networks — usually in the form of remote access credentials — as well as compromised databases containing large amounts of personal and financial data.

In an analysis published in February 2019, cyber intelligence firm Flashpoint called x999xx one of the most senior and prolific members of the top-tier Russian-language cybercrime forum Exploit, where x999xx could be seen frequently advertising the sale of stolen databases and network credentials.

In August 2023, x999xx sold access to a company that develops software for the real estate industry. In July 2023, x999xx advertised the sale of Social Security numbers, names, and birthdays for the citizenry of an entire U.S. state (unnamed in the auction).

A month earlier, x999xx posted a sales thread for 80 databases taken from Australia’s largest retail company. “You may use this data to demand a ransom or do something different with it,” x999xx wrote on Exploit. “Unfortunately, the flaw was patched fast. [+] no one has used the data yet [+] the data hasn’t been used to send spam [+] the data is waiting for its time.”

In October 2022, x999xx sold administrative access to a U.S. healthcare provider.

ALIAS: MAXNM

The oldest account by the name x999xx appeared in 2009 on the Russian language cybercrime forum Verified, under the email address maxnm@ozersk.com. Ozersk is a city in the Chelyabinsk region of west-central Russia.

According to the breach tracking service Constella Intelligence, the address maxnm@ozersk.com was used more than a decade ago to create an account at Vktontakte (the Russian answer to Facebook) under the name Maxim Kirtsov from Ozersk. Mr. Kirtsov’s profile — “maxnm” — says his birthday is September 5, 1991.

Personal photos Maxnm shared on Vktontakte in 2016. The caption has been machine translated from Russian.

The user x999xx registered on the Russian language cybercrime community Zloy in 2014 using the email address maxnmalias-1@yahoo.com. Constella says this email address was used in 2022 at the Russian shipping service cdek.ru in by a Maksim Georgievich Kirtsov from Ozersk.

Additional searches on these contact details reveal that prior to 2009, x999xx favored the handle Maxnm on Russian cybercrime forums. Cyber intelligence company Intel 471 finds the user Maxnm registered on Zloy in 2006 from an Internet address in Chelyabinsk, using the email address kirtsov@telecom.ozersk.ru.

That same email address was used to create Maxnm accounts on several other crime forums, including Spamdot and Exploit in 2005 (also from Chelyabinsk), and Damagelab in 2006.

A search in Constella for the Russian version of Kirtsov’s full name — Кирцов Максим Георгиевич — brings up multiple accounts registered to maksya@icloud.com.

A review of the digital footprint for maksya@icloud.com at osint.industries reveals this address was used a decade ago to register a still-active account at imageshack.com under the name x999xx. That account features numerous screenshots of financial statements from various banks, chat logs with other hackers, and even hacked websites.

x999xx’s Imageshack account includes screenshots of bank account balances from dozens of financial institutions, as well as chat logs with other hackers and pictures of homegrown weed.

Some of the photos in that Imageshack account also appear on Kirtsov’s Vkontakte page, including images of vehicles he owns, as well as pictures of potted marijuana plants. Kirtsov’s Vkontakte profile says that in 2012 he was a faculty member of the Ozersk Technological Institute National Research Nuclear University.

The Vkontakte page lists Kirtsov’s occupation as a website called ozersk[.]today, which on the surface appears to be a blog about life in Ozersk. However, in 2019 the security firm Recorded Future published a blog post which found this domain was being used to host a malicious Cobalt Strike server.

Cobalt Strike is a commercial network penetration testing and reconnaissance tool that is sold only to vetted partners. But stolen or ill-gotten Cobalt Strike licenses are frequently abused by cybercriminal gangs to help lay the groundwork for the installation of ransomware on a victim network.

In August 2023, x999xx posted a message on Exploit saying he was interested in buying a licensed version of Cobalt Strike. A month earlier, x999xx filed a complaint on Exploit against another forum member named Cobaltforce, an apparent onetime partner whose sudden and prolonged disappearance from the community left x999xx and others in the lurch. Cobaltforce recruited people experienced in using Cobalt Strike for ransomware operations, and offered to monetize access to hacked networks for a share of the profits.

DomainTools.com finds ozersk[.]today was registered to the email address dashin2008@yahoo.com, which also was used to register roughly two dozen other domains, including x999xx[.]biz. Virtually all of those domains were registered to Maxim Kirtsov from Ozersk. Below is a mind map used to track the identities mentioned in this story.

A visual depiction of the data points connecting x999xx to Max Kirtsov.

x999xx is a prolific member of the Russian webmaster forum “Gofuckbiz,” with more than 2,000 posts over nearly a decade, according to Intel 471. In one post from 2016, x999xx asked whether anyone knew where he could buy a heat lamp that simulates sunlight, explaining that one his pet rabbits had recently perished for lack of adequate light and heat. Mr. Kirtsov’s Vkontakte page includes several pictures of caged rabbits from 2015 and earlier.

CONFIRMATION

Reached via email, Mr. Kirtsov acknowledged that he is x999xx. Kirtsov said he and his team are also regular readers of KrebsOnSecurity.

“We’re glad to hear and read you,” Kirtsov replied.

Asked whether he was concerned about the legal and moral implications of his work, Kirtsov downplayed his role in ransomware intrusions, saying he was more focused on harvesting data.

“I consider myself as committed to ethical practices as you are,” Kirtsov wrote. “I have also embarked on research and am currently mentoring students. You may have noticed my activities on a forum, which I assume you know of through information gathered from public sources, possibly using the new tool you reviewed.”

“Regarding my posts about selling access, I must honestly admit, upon reviewing my own actions, I recall such mentions but believe they were never actualized,” he continued. “Many use the forum for self-serving purposes, which explains why listings of targets for sale have dwindled — they simply ceased being viable.”

Kirtsov asserted that he is not interested in harming healthcare institutions, just in stealing their data.

“As for health-related matters, I was once acquainted with affluent webmasters who would pay up to $50 for every 1000 health-themed emails,” Kirtsov said. “Therefore, I had no interest in the more sensitive data from medical institutions like X-rays, insurance numbers, or even names; I focused solely on emails. I am proficient in SQL, hence my ease with handling data like IDs and emails. And i never doing spam or something like this.”

On the Russian crime forums, x999xx said he never targets anything or anyone in Russia, and that he has little to fear from domestic law enforcement agencies provided he remains focused on foreign adversaries.

x999xx’s lackadaisical approach to personal security mirrors that of Wazawaka, another top Russian access broker who sold access to countless organizations and even operated his own ransomware affiliate programs.

“Don’t shit where you live, travel local, and don’t go abroad,” Wazawaka said of his own personal mantra. “Mother Russia will help you. Love your country, and you will always get away with everything.”

In January 2022, KrebsOnSecurity followed clues left behind by Wazawaka to identify him as 32-year-old Mikhail Matveev from Khakassia, Russia. In May 2023, the U.S. Department of Justice indicted Matveev as a key figure in several ransomware groups that collectively extorted hundreds of millions of dollars from victim organizations. The U.S. State Department is offering a $10 million reward for information leading to the capture and/or prosecution of Matveev.

Perhaps in recognition that many top ransomware criminals are largely untouchable so long as they remain in Russia, western law enforcement agencies have begun focusing more on getting inside the heads of those individuals. These so-called “psyops” are aimed at infiltrating ransomware-as-a-service operations, disrupting major cybercrime services, and decreasing trust within cybercriminal communities.

When authorities in the U.S. and U.K. announced in February 2024 that they’d infiltrated and seized the infrastructure used by the infamous LockBit ransomware gang, they borrowed the existing design of LockBit’s victim shaming website to link instead to press releases about the takedown, and included a countdown timer that was eventually replaced with the personal details of LockBit’s alleged leader.

In May 2024, law enforcement agencies in the United States and Europe announced Operation Endgame, a coordinated action against some of the most popular cybercrime platforms for delivering ransomware and data-stealing malware. The Operation Endgame website also included a countdown timer, which served to tease the release of several animated videos that mimic the same sort of flashy, short advertisements that established cybercriminals often produce to promote their services online.

A 22-year-old man from the United Kingdom arrested this week in Spain is allegedly the ringleader of Scattered Spider, a cybercrime group suspected of hacking into Twilio, LastPass, DoorDash, Mailchimp, and nearly 130 other organizations over the past two years.

The Spanish daily Murcia Today reports the suspect was wanted by the FBI and arrested in Palma de Mallorca as he tried to board a flight to Italy.

A still frame from a video released by the Spanish national police shows Tylerb in custody at the airport.

“He stands accused of hacking into corporate accounts and stealing critical information, which allegedly enabled the group to access multi-million-dollar funds,” Murcia Today wrote. “According to Palma police, at one point he controlled Bitcoins worth $27 million.”

The cybercrime-focused Twitter/X account vx-underground said the U.K. man arrested was a SIM-swapper who went by the alias “Tyler.” 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 sent to the victim — including one-time passcodes for authentication, or password reset links sent via SMS.

“He is a known SIM-swapper and is allegedly involved with the infamous Scattered Spider group,” vx-underground wrote on June 15, referring to a prolific gang implicated in costly data ransom attacks at MGM and Caesars casinos in Las Vegas last year.

Sources familiar with the investigation told KrebsOnSecurity the accused is a 22-year-old from Dundee, Scotland named Tyler Buchanan, also allegedly known as “tylerb” on Telegram chat channels centered around SIM-swapping.

In January 2024, U.S. authorities arrested another alleged Scattered Spider member — 19-year-old Noah Michael Urban of Palm Coast, Fla. — and charged him with stealing at least $800,000 from five victims between August 2022 and March 2023. Urban allegedly went by the nicknames “Sosa” and “King Bob,” and is believed to be part of the same crew that hacked Twilio and a slew of other companies in 2022.

Investigators say Scattered Spider members are part of a more diffuse cybercriminal community online known as “The Com,” wherein hackers from different cliques boast loudly about high-profile cyber thefts that almost invariably begin with social engineering — tricking people over the phone, email or SMS into giving away credentials that allow remote access to corporate internal networks.

One of the more popular SIM-swapping channels on Telegram maintains a frequently updated leaderboard of the most accomplished SIM-swappers, indexed by their supposed conquests in stealing cryptocurrency. That leaderboard currently lists Sosa as #24 (out of 100), and Tylerb at #65.

0KTAPUS

In August 2022, KrebsOnSecurity wrote about peering inside the 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 dubbed the gang by a different name — 0ktapus, a nod to how the criminal group phished employees for credentials.

The missives asked users to click a link and log in at a phishing page that mimicked their employer’s Okta authentication page. Those who submitted credentials were then prompted to provide the one-time password needed for multi-factor authentication.

These phishing attacks used newly-registered domains that often included the name of the targeted company, and sent text messages urging employees to click on links to these domains to view information about a pending change in their work schedule. The phishing sites also featured a hidden 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.

One of Scattered Spider’s first big victims in its 2022 SMS phishing spree was Twilio, a company that provides services for making and receiving text messages and phone calls. The group then pivoted, using their access to Twilio to attack at least 163 of its customers.

A Scattered Spider phishing lure sent to Twilio employees.

Among those was the encrypted messaging app Signal, which said the breach could have let attackers re-register the phone number on another device for about 1,900 users.

Also in August 2022, several employees at email delivery firm Mailchimp provided their remote access credentials to this phishing group. According to Mailchimp, the attackers used their access to Mailchimp employee accounts to steal data from 214 customers involved in cryptocurrency and finance.

On August 25, 2022, the password manager service LastPass disclosed a breach in which attackers stole some source code and proprietary LastPass technical information, and weeks later LastPass said an investigation revealed no customer data or password vaults were accessed.

However, on November 30, 2022 LastPass disclosed a far more serious breach that the company said leveraged data stolen in the August breach. LastPass said criminal hackers had stolen encrypted copies of some password vaults, as well as other personal information.

In February 2023, LastPass disclosed that the intrusion involved a highly complex, targeted attack against an engineer who was one of only four LastPass employees with access to the corporate vault. In that incident, the attackers exploited a security vulnerability in a Plex media server that the employee was running on his home network, and succeeded in installing malicious software that stole passwords and other authentication credentials. The vulnerability exploited by the intruders was patched back in 2020, but the employee never updated his Plex software.

Plex announced its own data breach one day before LastPass disclosed its initial August intrusion. On August 24, 2022, Plex’s security team urged users to reset their passwords, saying an intruder had accessed customer emails, usernames and encrypted passwords.

TURF WARS

Sosa and Tylerb were both subjected to physical attacks from rival SIM-swapping gangs. These communities have been known to settle scores by turning to so-called “violence-as-a-service” offerings on cybercrime channels, wherein people can be hired to perform a variety geographically-specific “in real life” jobs, such as bricking windows, slashing car tires, or even home invasions.

In 2022, a video surfaced on a popular cybercrime channel purporting to show attackers hurling a brick through a window at an address that matches the spacious and upscale home of Urban’s parents in Sanford, Fl.

January’s story on Sosa noted that a junior member of his crew named “Foreshadow” was kidnapped, beaten and held for ransom in September 2022. Foreshadow’s captors held guns to his bloodied head while forcing him to record a video message pleading with his crew to fork over a $200,000 ransom in exchange for his life (Foreshadow escaped further harm in that incident).

According to several SIM-swapping channels on Telegram where Tylerb was known to frequent, rival SIM-swappers hired thugs to invade his home in February 2023. Those accounts state that the intruders assaulted Tylerb’s mother in the home invasion, and that they threatened to burn him with a blowtorch if he didn’t give up the keys to his cryptocurrency wallets. Tylerb was reputed to have fled the United Kingdom after that assault.

KrebsOnSecurity sought comment from Mr. Buchanan, and will update this story in the event he responds.

Law enforcement agencies in the United States and Europe today announced Operation Endgame, a coordinated action against some of the most popular cybercrime platforms for delivering ransomware and data-stealing malware. Dubbed “the largest ever operation against botnets,” the international effort is being billed as the opening salvo in an ongoing campaign targeting advanced malware “droppers” or “loaders” like IcedID, Smokeloader and Trickbot.

A frame from one of three animated videos released today in connection with Operation Endgame.

Operation Endgame targets the cybercrime ecosystem supporting droppers/loaders, slang terms used to describe tiny, custom-made programs designed to surreptitiously install malware onto a target system. Droppers are typically used in the initial stages of a breach, and they allow cybercriminals to bypass security measures and deploy additional harmful programs, including viruses, ransomware, or spyware.

Droppers like IcedID are most often deployed through email attachments, hacked websites, or bundled with legitimate software. For example, cybercriminals have long used paid ads on Google to trick people into installing malware disguised as popular free software, such as Microsoft Teams, Adobe Reader and Discord. In those cases, the dropper is the hidden component bundled with the legitimate software that quietly loads malware onto the user’s system.

Droppers remain such a critical, human-intensive component of nearly all major cybercrime enterprises that the most popular have turned into full-fledged cybercrime services of their own. By targeting the individuals who develop and maintain dropper services and their supporting infrastructure, authorities are hoping to disrupt multiple cybercriminal operations simultaneously.

According to a statement from the European police agency Europol, between May 27 and May 29, 2024 authorities arrested four suspects (one in Armenia and three in Ukraine), and disrupted or took down more than 100 Internet servers in Bulgaria, Canada, Germany, Lithuania, the Netherlands, Romania, Switzerland, the United Kingdom, United States and Ukraine. Authorities say they also seized more than 2,000 domain names that supported dropper infrastructure online.

In addition, Europol released information on eight fugitives suspected of involvement in dropper services and who are wanted by Germany; their names and photos were added to Europol’s “Most Wanted” list on 30 May 2024.

A “wanted” poster including the names and photos of eight suspects wanted by Germany and now on Europol’s “Most Wanted” list.

“It has been discovered through the investigations so far that one of the main suspects has earned at least EUR 69 million in cryptocurrency by renting out criminal infrastructure sites to deploy ransomware,” Europol wrote. “The suspect’s transactions are constantly being monitored and legal permission to seize these assets upon future actions has already been obtained.”

There have been numerous such coordinated malware takedown efforts in the past, and yet often the substantial amount of coordination required between law enforcement agencies and cybersecurity firms involved is not sustained after the initial disruption and/or arrests.

But a new website erected to detail today’s action — operation-endgame.com — makes the case that this time is different, and that more takedowns and arrests are coming. “Operation Endgame does not end today,” the site promises. “New actions will be announced on this website.”

A message on operation-endgame.com promises more law enforcement and disruption actions.

Perhaps in recognition that many of today’s top cybercriminals reside in countries that are effectively beyond the reach of international law enforcement, actions like Operation Endgame seem increasingly focused on mind games — i.e., trolling the hackers.

Writing in this month’s issue of Wired, Matt Burgess makes the case that Western law enforcement officials have turned to psychological measures as an added way to slow down Russian hackers and cut to the heart of the sweeping cybercrime ecosystem.

“These nascent psyops include efforts to erode the limited trust the criminals have in each other, driving subtle wedges between fragile hacker egos, and sending offenders personalized messages showing they’re being watched,” Burgess wrote.

When authorities in the U.S. and U.K. announced in February 2024 that they’d infiltrated and seized the infrastructure used by the infamous LockBit ransomware gang, they borrowed the existing design of LockBit’s victim shaming website to link instead to press releases about the takedown, and included a countdown timer that was eventually replaced with the personal details of LockBit’s alleged leader.

The feds used the existing design on LockBit’s victim shaming website to feature press releases and free decryption tools.

The Operation Endgame website also includes a countdown timer, which serves to tease the release of several animated videos that mimic the same sort of flashy, short advertisements that established cybercriminals often produce to promote their services online. At least two of the videos include a substantial amount of text written in Russian.

The coordinated takedown comes on the heels of another law enforcement action this week against what the director of the FBI called “likely the world’s largest botnet ever.” On Wednesday U.S. Department of Justice (DOJ) announced the arrest of YunHe Wang, the alleged operator of the ten-year-old online anonymity service 911 S5. The government also seized 911 S5’s domains and online infrastructure, which allegedly turned computers running various “free VPN” products into Internet traffic relays that facilitated billions of dollars in online fraud and cybercrime.

Last week, the United States joined the U.K. and Australia in sanctioning and charging a Russian man named Dmitry Yuryevich Khoroshev as the leader of the infamous LockBit ransomware group. LockBit’s leader “LockBitSupp” claims the feds named the wrong guy, saying the charges don’t explain how they connected him to Khoroshev. This post examines the activities of Khoroshev’s many alter egos on the cybercrime forums, and tracks the career of a gifted malware author who has written and sold malicious code for the past 14 years.

On May 7, the U.S. Department of Justice indicted Khoroshev on 26 criminal counts, including extortion, wire fraud, and conspiracy. The government alleges Khoroshev created, sold and used the LockBit ransomware strain to personally extort more than $100 million from hundreds of victim organizations, and that LockBit as a group extorted roughly half a billion dollars over four years.

Federal investigators say Khoroshev ran LockBit as a “ransomware-as-a-service” operation, wherein he kept 20 percent of any ransom amount paid by a victim organization infected with his code, with the remaining 80 percent of the payment going to LockBit affiliates responsible for spreading the malware.

Financial sanctions levied against Khoroshev by the U.S. Department of the Treasury listed his known email and street address (in Voronezh, in southwest Russia), passport number, and even his tax ID number (hello, Russian tax authorities). The Treasury filing says Khoroshev used the emails sitedev5@yandex.ru, and khoroshev1@icloud.com.

According to DomainTools.com, the address sitedev5@yandex.ru was used to register at least six domains, including a Russian business registered in Khoroshev’s name called tkaner.com, which is a blog about clothing and fabrics.

A search at the breach-tracking service Constella Intelligence on the phone number in Tkaner’s registration records  — 7.9521020220 — brings up multiple official Russian government documents listing the number’s owner as Dmitri Yurievich Khoroshev.

Another domain registered to that phone number was stairwell[.]ru, which at one point advertised the sale of wooden staircases. Constella finds that the email addresses webmaster@stairwell.ru and admin@stairwell.ru used the password 225948.

DomainTools reports that stairwell.ru for several years included the registrant’s name as “Dmitrij Ju Horoshev,” and the email address pin@darktower.su. According to Constella, this email address was used in 2010 to register an account for a Dmitry Yurievich Khoroshev from Voronezh, Russia at the hosting provider firstvds.ru.

Cyber intelligence firm Intel 471 finds that pin@darktower.ru was used by a Russian-speaking member called Pin on the English-language cybercrime forum Opensc. Pin was active on Opensc around March 2012, and authored 13 posts that mostly concerned data encryption issues, or how to fix bugs in code.

Other posts concerned custom code Pin claimed to have written that would bypass memory protections on Windows XP and Windows 7 systems, and inject malware into memory space normally allocated to trusted applications on a Windows machine.

Pin also was active at that same time on the Russian-language security forum Antichat, where they told fellow forum members to contact them at the ICQ instant messenger number 669316.

NEROWOLFE

A search on the ICQ number 669316 at Intel 471 shows that in April 2011, a user by the name NeroWolfe joined the Russian cybercrime forum Zloy using the email address d.horoshev@gmail.com, and from an Internet address in Voronezh, RU.

Constella finds the same password tied to webmaster@stairwell.ru (225948) was used by the email address 3k@xakep.ru, which Intel 471 says was registered to more than a dozen NeroWolfe accounts across just as many Russian cybercrime forums between 2011 and 2015.

NeroWolfe’s introductory post to the forum Verified in Oct. 2011 said he was a system administrator and C++ coder.

“Installing SpyEYE, ZeuS, any DDoS and spam admin panels,” NeroWolfe wrote. This user said they specialize in developing malware, creating computer worms, and crafting new ways to hijack Web browsers.

“I can provide my portfolio on request,” NeroWolfe wrote. “P.S. I don’t modify someone else’s code or work with someone else’s frameworks.”

In April 2013, NeroWolfe wrote in a private message to another Verified forum user that he was selling a malware “loader” program that could bypass all of the security protections on Windows XP and Windows 7.

“The access to the network is slightly restricted,” NeroWolfe said of the loader, which he was selling for $5,000. “You won’t manage to bind a port. However, it’s quite possible to send data. The code is written in C.”

In an October 2013 discussion on the cybercrime forum Exploit, NeroWolfe weighed in on the karmic ramifications of ransomware. At the time, ransomware-as-a-service didn’t exist yet, and many members of Exploit were still making good money from “lockers,” relatively crude programs that locked the user out of their system until they agreed to make a small payment (usually a few hundred dollars via prepaid Green Dot cards).

Lockers, which presaged the coming ransomware scourge, were generally viewed by the Russian-speaking cybercrime forums as harmless moneymaking opportunities, because they usually didn’t seek to harm the host computer or endanger files on the system. Also, there were still plenty of locker programs that aspiring cybercriminals could either buy or rent to make a steady income.

NeroWolfe reminded forum denizens that they were just as vulnerable to ransomware attacks as their would-be victims, and that what goes around comes around.

“Guys, do you have a conscience?,” NeroWolfe wrote. “Okay, lockers, network gopstop aka business in Russian. The last thing was always squeezed out of the suckers. But encoders, no one is protected from them, including the local audience.”

If Khoroshev was ever worried that someone outside of Russia might be able to connect his early hacker handles to his real life persona, that’s not clear from reviewing his history online. In fact, the same email address tied to so many of NeroWolfe’s accounts on the forums — 3k@xakep.ru — was used in 2011 to create an account for a Dmitry Yurevich Khoroshev on the Russian social media network Vkontakte.

NeroWolfe seems to have abandoned all of his forum accounts sometime in 2016. In November 2016, an exploit[.]ru member filed an official complaint against NeroWolfe, saying NeroWolfe had been paid $2,000 to produce custom code but never finished the project and vanished.

It’s unclear what happened to NeroWolfe or to Khoroshev during this time. Maybe he got arrested, or some close associates did. Perhaps he just decided it was time to lay low and hit the reset on his operational security efforts, given his past failures in this regard. It’s also possible NeroWolfe landed a real job somewhere for a few years, fathered a child, and/or had to put his cybercrime career on hold.

PUTINKRAB

Or perhaps Khoroshev saw the coming ransomware industry for the endless pot of gold that it was about to become, and then dedicated himself to working on custom ransomware code. That’s what the government believes.

The indictment against Khoroshev says he used the hacker nickname Putinkrab, and Intel 471 says this corresponds to a username that was first registered across three major Russian cybercrime forums in early 2019.

KrebsOnSecurity could find no obvious connections between Putinkrab and any of Khoroshev’s older identities. However, if Putinkrab was Khoroshev, he would have learned from his past mistakes and started fresh with a new identity (which he did). But also, it is likely the government hasn’t shared all of the intelligence it has collected against him (more on that in a bit).

Putinkrab’s first posts on the Russian cybercrime forums XSS, Exploit and UFOLabs saw this user selling ransomware source code written in C.

In April 2019, Putkinkrab offered an affiliate program that would run on top of his custom-made ransomware code.

“I want to work for a share of the ransoms: 20/80,” Putinkrab wrote on Exploit. “20 percent is my percentage for the work, you get 80% of the ransoms. The percentage can be reduced up to 10/90 if the volumes are good. But now, temporarily, until the service is fully automated, we are working using a different algorithm.”

Throughout the summer of 2019, Putinkrab posted multiple updates to Exploit about new features being added to his ransomware strain, as well as novel evasion techniques to avoid detection by security tools. He also told forum members he was looking for investors for a new ransomware project based on his code.

In response to an Exploit member who complained that the security industry was making it harder to profit from ransomware, Putinkrab said that was because so many cybercriminals were relying on crappy ransomware code.

“The vast majority of top antiviruses have acquired behavioral analysis, which blocks 95% of crypto-lockers at their root,” Putinkrab wrote. “Cryptolockers made a lot of noise in the press, but lazy system administrators don’t make backups after that. The vast majority of cryptolockers are written by people who have little understanding of cryptography. Therefore, decryptors appear on the Internet, and with them the hope that files can be decrypted without paying a ransom. They just sit and wait. Contact with the owner of the key is lost over time.”

Putinkrab said he had every confidence his ransomware code was a game-changer, and a huge money machine.

“The game is just gaining momentum,” Putinkrab wrote. “Weak players lose and are eliminated.”

The rest of his response was structured like a poem:

“In this world, the strongest survive.
Our life is just a struggle.
The winner will be the smartest,
Who has his head on his shoulders.”

Putinkrab’s final post came on August 23, 2019. The Justice Department says the LockBit ransomware affiliate program was officially launched five months later. From there on out, the government says, Khoroshev adopted the persona of LockBitSupp. In his introductory post on Exploit, LockBit’s mastermind said the ransomware strain had been in development since September 2019.

The original LockBit malware was written in C (a language that NeroWolfe excelled at). Here’s the original description of LockBit, from its maker:

“The software is written in C and Assembler; encryption is performed through the I/O Completion Port; there is a port scanning local networks and an option to find all DFS, SMB, WebDAV network shares, an admin panel in Tor, automatic test decryption; a decryption tool is provided; there is a chat with Push notifications, a Jabber bot that forwards correspondence and an option to terminate services/processes in line which prevent the ransomware from opening files at a certain moment. The ransomware sets file permissions and removes blocking attributes, deletes shadow copies, clears logs and mounts hidden partitions; there is an option to drag-and-drop files/folders and a console/hidden mode. The ransomware encrypts files in parts in various places: the larger the file size, the more parts there are. The algorithms used are AES + RSA.

You are the one who determines the ransom amount after communicating with the victim. The ransom paid in any currency that suits you will be transferred to your wallets. The Jabber bot serves as an admin panel and is used for banning, providing decryption tools, chatting – Jabber is used for absolutely everything.”

CONCLUSION

Does the above timeline prove that NeroWolfe/Khoroshev is LockBitSupp? No. However, it does indicate Khoroshev was for many years deeply invested in countless schemes involving botnets, stolen data, and malware he wrote that others used to great effect. NeroWolfe’s many private messages from fellow forum members confirm this.

NeroWolfe’s specialty was creating custom code that employed novel stealth and evasion techniques, and he was always quick to volunteer his services on the forums whenever anyone was looking help on a malware project that called for a strong C or C++ programmer.

Someone with those qualifications — as well as demonstrated mastery of data encryption and decryption techniques — would have been in great demand by the ransomware-as-a-service industry that took off at around the same time NeroWolfe vanished from the forums.

Someone like that who is near or at the top of their game vis-a-vis their peers does not simply walk away from that level of influence, community status, and potential income stream unless forced to do so by circumstances beyond their immediate control.

It’s important to note that Putinkrab didn’t just materialize out of thin air in 2019 — suddenly endowed with knowledge about how to write advanced, stealthy ransomware strains. That knowledge clearly came from someone who’d already had years of experience building and deploying ransomware strains against real-life victim organizations.

Thus, whoever Putinkrab was before they adopted that moniker, it’s a safe bet they were involved in the development and use of earlier, highly successful ransomware strains. One strong possible candidate is Cerber ransomware, the most popular and effective affiliate program operating between early 2016 and mid-2017. Cerber thrived because it emerged as an early mover in the market for ransomware-as-a-service offerings.

In February 2024, the FBI seized LockBit’s cybercrime infrastructure on the dark web, following an apparently lengthy infiltration of the group’s operations. The United States has already indicted and sanctioned at least five other alleged LockBit ringleaders or affiliates, so presumably the feds have been able to draw additional resources from those investigations.

Also, it seems likely that the three national intelligence agencies involved in bringing these charges are not showing all of their cards. For example, the Treasury documents on Khoroshev mention a single cryptocurrency address, and yet experts interviewed for this story say there are no obvious clues connecting this address to Khoroshev or Putinkrab.

But given that LockBitSupp has been actively involved in Lockbit ransomware attacks against organizations for four years now, the government almost certainly has an extensive list of the LockBit leader’s various cryptocurrency addresses — and probably even his bank accounts in Russia. And no doubt the money trail from some of those transactions was traceable to its ultimate beneficiary (or close enough).

Not long after Khoroshev was charged as the leader of LockBit, a number of open-source intelligence accounts on Telegram began extending the information released by the Treasury Department. Within hours, these sleuths had unearthed more than a dozen credit card accounts used by Khoroshev over the past decade, as well as his various bank account numbers in Russia.

The point is, this post is based on data that’s available to and verifiable by KrebsOnSecurity. Woodward & Bernstein’s source in the Watergate investigation — Deep Throat — famously told the two reporters to “follow the money.” This is always excellent advice. But these days, that can be a lot easier said than done — especially with people who a) do not wish to be found, and b) don’t exactly file annual reports.

The United States joined the United Kingdom and Australia today in sanctioning 31-year-old Russian national Dmitry Yuryevich Khoroshev as the alleged leader of the infamous ransomware group LockBit. The U.S. Department of Justice also indicted Khoroshev and charged him with using Lockbit to attack more than 2,000 victims and extort at least $100 million in ransomware payments.

Khoroshev (Дмитрий Юрьевич Хорошев), a resident of Voronezh, Russia, was charged in a 26-count indictment by a grand jury in New Jersey.

“Dmitry Khoroshev conceived, developed, and administered Lockbit, the most prolific ransomware variant and group in the world, enabling himself and his affiliates to wreak havoc and cause billions of dollars in damage to thousands of victims around the globe,” U.S. Attorney Philip R. Sellinger said in a statement released by the Justice Department.

The indictment alleges Khoroshev acted as the LockBit ransomware group’s developer and administrator from its inception in September 2019 through May 2024, and that he typically received a 20 percent share of each ransom payment extorted from LockBit victims.

The government says LockBit victims included individuals, small businesses, multinational corporations, hospitals, schools, nonprofit organizations, critical infrastructure, and government and law-enforcement agencies.

“Khoroshev and his co-conspirators extracted at least $500 million in ransom payments from their victims and caused billions of dollars in broader losses, such as lost revenue, incident response, and recovery,” the DOJ said. “The LockBit ransomware group attacked more than 2,500 victims in at least 120 countries, including 1,800 victims in the United States.”

The unmasking of LockBitSupp comes nearly three months after U.S. and U.K. authorities seized the darknet websites run by LockBit, retrofitting it with press releases about the law enforcement action and free tools to help LockBit victims decrypt infected systems.

The feds used the existing design on LockBit’s victim shaming website to feature press releases and free decryption tools.

One of the blog captions that authorities left on the seized site was a teaser page that read, “Who is LockbitSupp?,” which promised to reveal the true identity of the ransomware group leader. That item featured a countdown clock until the big reveal, but when the site’s timer expired no such details were offered.

Following the FBI’s raid, LockBitSupp took to Russian cybercrime forums to assure his partners and affiliates that the ransomware operation was still fully operational. LockBitSupp also raised another set of darknet websites that soon promised to release data stolen from a number of LockBit victims ransomed prior to the FBI raid.

One of the victims LockBitSupp continued extorting was Fulton County, Ga. Following the FBI raid, LockbitSupp vowed to release sensitive documents stolen from the county court system unless paid a ransom demand before LockBit’s countdown timer expired. But when Fulton County officials refused to pay and the timer expired, no stolen records were ever published. Experts said it was likely the FBI had in fact seized all of LockBit’s stolen data.

LockBitSupp also bragged that their real identity would never be revealed, and at one point offered to pay $10 million to anyone who could discover their real name.

KrebsOnSecurity has been in intermittent contact with LockBitSupp for several months over the course of reporting on different LockBit victims. Reached at the same ToX instant messenger identity that the ransomware group leader has promoted on Russian cybercrime forums, LockBitSupp claimed the authorities named the wrong guy.

“It’s not me,” LockBitSupp replied in Russian. “I don’t understand how the FBI was able to connect me with this poor guy. Where is the logical chain that it is me? Don’t you feel sorry for a random innocent person?”

LockBitSupp, who now has a $10 million bounty for his arrest from the U.S. Department of State, has been known to be flexible with the truth. The Lockbit group routinely practiced “double extortion” against its victims — requiring one ransom payment for a key to unlock hijacked systems, and a separate payment in exchange for a promise to delete data stolen from its victims.

But Justice Department officials say LockBit never deleted its victim data, regardless of whether those organizations paid a ransom to keep the information from being published on LockBit’s victim shaming website.

Khoroshev is the sixth person officially indicted as active members of LockBit. The government says Russian national Artur Sungatov used LockBit ransomware against victims in manufacturing, logistics, insurance and other companies throughout the United States.

Ivan Gennadievich Kondratyev, a.k.a. “Bassterlord,” allegedly deployed LockBit against targets in the United States, Singapore, Taiwan, and Lebanon. Kondratyev is also charged (PDF) with three criminal counts arising from his alleged use of the Sodinokibi (aka “REvil“) ransomware variant to encrypt data, exfiltrate victim information, and extort a ransom payment from a corporate victim based in Alameda County, California.

In May 2023, U.S. authorities unsealed indictments against two alleged LockBit affiliates, Mikhail “Wazawaka” Matveev and Mikhail Vasiliev. In January 2022, KrebsOnSecurity published Who is the Network Access Broker ‘Wazawaka,’ which followed clues from Wazawaka’s many pseudonyms and contact details on the Russian-language cybercrime forums back to a 31-year-old Mikhail Matveev from Abaza, RU.

Matveev remains at large, presumably still in Russia. Meanwhile, the U.S. Department of State has a standing $10 million reward offer for information leading to Matveev’s arrest.

Vasiliev, 35, of Bradford, Ontario, Canada, is in custody in Canada awaiting extradition to the United States (the complaint against Vasiliev is at this PDF).

In June 2023, Russian national Ruslan Magomedovich Astamirov was charged in New Jersey for his participation in the LockBit conspiracy, including the deployment of LockBit against victims in Florida, Japan, France, and Kenya. Astamirov is currently in custody in the United States awaiting trial.

The Justice Department is urging victims targeted by LockBit to contact the FBI at https://lockbitvictims.ic3.gov/ to file an official complaint, and to determine whether affected systems can be successfully decrypted.
