Microsoft Patch Tuesday, February 2025 Edition

Microsoft today issued security updates to fix at least 56 vulnerabilities in its Windows operating systems and supported software, including two zero-day flaws that are being actively exploited.

All supported Windows operating systems will receive an update this month for a buffer overflow vulnerability that carries the catchy name CVE-2025-21418. This patch should be a priority for enterprises, as Microsoft says it is being exploited, has low attack complexity, and no requirements for user interaction.

Tenable senior staff research engineer Satnam Narang noted that since 2022, there have been nine elevation of privilege vulnerabilities in this same Windows component — three each year — including one in 2024 that was exploited in the wild as a zero day (CVE-2024-38193).

“CVE-2024-38193 was exploited by the North Korean APT group known as Lazarus Group to implant a new version of the FudModule rootkit in order to maintain persistence and stealth on compromised systems,” Narang said. “At this time, it is unclear if CVE-2025-21418 was also exploited by Lazarus Group.”

The other zero-day, CVE-2025-21391, is an elevation of privilege vulnerability in Windows Storage that could be used to delete files on a targeted system. Microsoft’s advisory on this bug references something called “CWE-59: Improper Link Resolution Before File Access,” says no user interaction is required, and that the attack complexity is low.

Adam Barnett, lead software engineer at Rapid7, said although the advisory provides scant detail, and even offers some vague reassurance that ‘an attacker would only be able to delete targeted files on a system,’ it would be a mistake to assume that the impact of deleting arbitrary files would be limited to data loss or denial of service.

“As long ago as 2022, ZDI researchers set out how a motivated attacker could parlay arbitrary file deletion into full SYSTEM access using techniques which also involve creative misuse of symbolic links,”Barnett wrote.

One vulnerability patched today that was publicly disclosed earlier is CVE-2025-21377, another weakness that could allow an attacker to elevate their privileges on a vulnerable Windows system. Specifically, this is yet another Windows flaw that can be used to steal NTLMv2 hashes — essentially allowing an attacker to authenticate as the targeted user without having to log in.

According to Microsoft, minimal user interaction with a malicious file is needed to exploit CVE-2025-21377, including selecting, inspecting or “performing an action other than opening or executing the file.”

“This trademark linguistic ducking and weaving may be Microsoft’s way of saying ‘if we told you any more, we’d give the game away,'” Barnett said. “Accordingly, Microsoft assesses exploitation as more likely.”

The SANS Internet Storm Center has a handy list of all the Microsoft patches released today, indexed by severity. Windows enterprise administrators would do well to keep an eye on askwoody.com, which often has the scoop on any patches causing problems.

It’s getting harder to buy Windows software that isn’t also bundled with Microsoft’s flagship Copilot artificial intelligence (AI) feature. Last month Microsoft started bundling Copilot with Microsoft Office 365, which Redmond has since rebranded as “Microsoft 365 Copilot.” Ostensibly to offset the costs of its substantial AI investments, Microsoft also jacked up prices from 22 percent to 30 percent for upcoming license renewals and new subscribers.

Office-watch.com writes that existing Office 365 users who are paying an annual cloud license do have the option of “Microsoft 365 Classic,” an AI-free subscription at a lower price, but that many customers are not offered the option until they attempt to cancel their existing Office subscription.

In other security patch news, Apple has shipped iOS 18.3.1, which fixes a zero day vulnerability (CVE-2025-24200) that is showing up in attacks.

Adobe has issued security updates that fix a total of 45 vulnerabilities across InDesign, Commerce, Substance 3D Stager, InCopy, Illustrator, Substance 3D Designer and Photoshop Elements.

Chris Goettl at Ivanti notes that Google Chrome is shipping an update today which will trigger updates for Chromium based browsers including Microsoft Edge, so be on the lookout for Chrome and Edge updates as we proceed through the week.

Despite Catastrophic Hacks, Ransomware Payments Dropped Dramatically Last Year

Ransomware gangs continued to wreak havoc in 2024, but new research shows that the amounts victims paid these cybercriminals fell by hundreds of millions of dollars.

Subaru Security Flaws Exposed Its System for Tracking Millions of Cars

Now-fixed web bugs allowed hackers to remotely unlock and start any of millions of Subarus. More disturbingly, they could also access at least a year of cars’ location histories—and Subaru employees still can.

Microsoft: Happy 2025. Here’s 161 Security Updates

Microsoft today unleashed updates to plug a whopping 161 security vulnerabilities in Windows and related software, including three “zero-day” weaknesses that are already under active attack. Redmond’s inaugural Patch Tuesday of 2025 bundles more fixes than the company has shipped in one go since 2017.

Rapid7‘s Adam Barnett says January marks the fourth consecutive month where Microsoft has published zero-day vulnerabilities on Patch Tuesday without evaluating any of them as critical severity at time of publication. Today also saw the publication of nine critical remote code execution (RCE) vulnerabilities.

The Microsoft flaws already seeing active attacks include CVE-2025-21333, CVE-2025-21334 and, you guessed it– CVE-2025-21335. These are sequential because all reside in Windows Hyper-V, a component that is heavily embedded in modern Windows 11 operating systems and used for security features including device guard and credential guard.

Tenable’s Satnam Narang says little is known about the in-the-wild exploitation of these flaws, apart from the fact that they are all “privilege escalation” vulnerabilities. Narang said we tend to see a lot of elevation of privilege bugs exploited in the wild as zero-days in Patch Tuesday because it’s not always initial access to a system that’s a challenge for attackers as they have various avenues in their pursuit.

“As elevation of privilege bugs, they’re being used as part of post-compromise activity, where an attacker has already accessed a target system,” he said. “It’s kind of like if an attacker is able to enter a secure building, they’re unable to access more secure parts of the facility because they have to prove that they have clearance. In this case, they’re able to trick the system into believing they should have clearance.”

Several bugs addressed today earned CVSS (threat rating) scores of 9.8 out of a possible 10, including CVE-2025-21298, a weakness in Windows that could allow attackers to run arbitrary code by getting a target to open a malicious .rtf file, documents typically opened on Office applications like Microsoft Word. Microsoft has rated this flaw “exploitation more likely.”

Ben Hopkins at Immersive Labs called attention to the CVE-2025-21311, a 9.8 “critical” bug in Windows NTLMv1 (NT LAN Manager version 1), an older Microsoft authentication protocol that is still used by many organizations.

“What makes this vulnerability so impactful is the fact that it is remotely exploitable, so attackers can reach the compromised machine(s) over the internet, and the attacker does not need significant knowledge or skills to achieve repeatable success with the same payload across any vulnerable component,” Hopkins wrote.

Kev Breen at Immersive points to an interesting flaw (CVE-2025-21210) that Microsoft fixed in its full disk encryption suite Bitlocker that the software giant has dubbed “exploitation more likely.” Specifically, this bug holds out the possibility that in some situations the hibernation image created when one closes the laptop lid on an open Windows session may not be fully encrypted and could be recovered in plain text.

“Hibernation images are used when a laptop goes to sleep and contains the contents that were stored in RAM at the moment the device powered down,” Breen noted. “This presents a significant potential impact as RAM can contain sensitive data (such as passwords, credentials and PII) that may have been in open documents or browser sessions and can all be recovered with free tools from hibernation files.”

Tenable’s Narang also highlighted a trio of vulnerabilities in Microsoft Access fixed this month and credited to Unpatched.ai, a security research effort that is aided by artificial intelligence looking for vulnerabilities in code. Tracked as CVE-2025-21186, CVE-2025-21366, and CVE-2025-21395, these are remote code execution bugs that are exploitable if an attacker convinces a target to download and run a malicious file through social engineering. Unpatched.ai was also credited with discovering a flaw in the December 2024 Patch Tuesday release (CVE-2024-49142).

“Automated vulnerability detection using AI has garnered a lot of attention recently, so it’s noteworthy to see this service being credited with finding bugs in Microsoft products,” Narang observed. “It may be the first of many in 2025.”

If you’re a Windows user who has automatic updates turned off and haven’t updated in a while, it’s probably time to play catch up. Please consider backing up important files and/or the entire hard drive before updating.

Patch Tuesday, December 2024 Edition

Microsoft today released updates to plug at least 70 security holes in Windows and Windows software, including one vulnerability that is already being exploited in active attacks.

The zero-day seeing exploitation involves CVE-2024-49138, a security weakness in the Windows Common Log File System (CLFS) driver — used by applications to write transaction logs — that could let an authenticated attacker gain “system” level privileges on a vulnerable Windows device.

The security firm Rapid7 notes there have been a series of zero-day elevation of privilege flaws in CLFS over the past few years.

“Ransomware authors who have abused previous CLFS vulnerabilities will be only too pleased to get their hands on a fresh one,” wrote Adam Barnett, lead software engineer at Rapid7. “Expect more CLFS zero-day vulnerabilities to emerge in the future, at least until Microsoft performs a full replacement of the aging CLFS codebase instead of offering spot fixes for specific flaws.”

Elevation of privilege vulnerabilities accounted for 29% of the 1,009 security bugs Microsoft has patched so far in 2024, according to a year-end tally by Tenable; nearly 40 percent of those bugs were weaknesses that could let attackers run malicious code on the vulnerable device.

Rob Reeves, principal security engineer at Immersive Labs, called special attention to CVE-2024-49112, a remote code execution flaw in the Lightweight Directory Access Protocol (LDAP) service on every version of Windows since Windows 7. CVE-2024-49112 has been assigned a CVSS (badness) score of 9.8 out of 10.

“LDAP is most commonly seen on servers that are Domain Controllers inside a Windows network and LDAP must be exposed to other servers and clients within an enterprise environment for the domain to function,” Reeves said. “Microsoft hasn’t released specific information about the vulnerability at present, but has indicated that the attack complexity is low and authentication is not required.”

Tyler Reguly at the security firm Fortra had a slightly different 2024 patch tally for Microsoft, at 1,088 vulnerabilities, which he said was surprisingly similar to the 1,063 vulnerabilities resolved in 2023 and the 1,119 vulnerabilities resolved in 2022.

“If nothing else, we can say that Microsoft is consistent,” Reguly said. “While it would be nice to see the number of vulnerabilities each year decreasing, at least consistency lets us know what to expect.”

If you’re a Windows end user and your system is not set up to automatically install updates, please take a minute this week to run Windows Update, preferably after backing up your system and/or important data.

System admins should keep an eye on AskWoody.com, which usually has the details if any of the Patch Tuesday fixes are causing problems. In the meantime, if you run into any problems applying this month’s fixes, please drop a note about in the comments below.

Feds Charge Five Men in ‘Scattered Spider’ Roundup

Federal prosecutors in Los Angeles this week unsealed criminal charges against five men alleged to be members of a hacking group responsible for dozens of cyber intrusions at major U.S. technology companies between 2021 and 2023, including LastPass, MailChimp, Okta, T-Mobile and Twilio.

The five men, aged 20 to 25, are allegedly members of a hacking conspiracy dubbed “Scattered Spider” and “Oktapus,” which specialized in SMS-based phishing attacks that tricked employees at tech firms into entering their credentials and one-time passcodes at phishing websites.

The targeted SMS scams asked employees to click a link and log in at a website that mimicked their employer’s Okta authentication page. Some SMS phishing messages told employees their VPN credentials were expiring and needed to be changed; other phishing messages advised employees about changes to their upcoming work schedule.

These attacks leveraged newly-registered domains that often included the name of the targeted company, such as twilio-help[.]com and ouryahoo-okta[.]com. The phishing websites were normally kept online for just one or two hours at a time, meaning they were often yanked offline before they could be flagged by anti-phishing and security services.

The phishing kits used for these campaigns featured a hidden Telegram instant message bot that forwarded any submitted credentials in real-time. The bot allowed the attackers to use the phished username, password and one-time code to log in as that employee at the real employer website.

In August 2022, multiple security firms gained access to the server that was receiving data from that Telegram bot, which on several occasions leaked the Telegram ID and handle of its developer, who used the nickname “Joeleoli.”

That Joeleoli moniker registered on the cybercrime forum OGusers in 2018 with the email address joelebruh@gmail.com, which also was used to register accounts at several websites for a Joel Evans from North Carolina. Indeed, prosecutors say Joeleoli’s real name is Joel Martin Evans, and he is a 25-year-old from Jacksonville, North Carolina.

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 used their access to Twilio to attack at least 163 of its customers. According to prosecutors, the group mainly sought to steal cryptocurrency from victim companies and their employees.

“The defendants allegedly preyed on unsuspecting victims in this phishing scheme and used their personal information as a gateway to steal millions in their cryptocurrency accounts,” said Akil Davis, the assistant director in charge of the FBI’s Los Angeles field office.

Many of the hacking group’s phishing domains were registered through the registrar NameCheap, and FBI investigators said records obtained from NameCheap showed the person who managed those phishing websites did so from an Internet address in Scotland. The feds then obtained records from Virgin Media, which showed the address was leased for several months to Tyler Buchanan, a 22-year-old from Dundee, Scotland.

As first reported here in June, Buchanan was arrested in Spain as he tried to board a flight bound for Italy. The Spanish police told local media that Buchanan, who allegedly went by the alias “Tylerb,” at one time possessed Bitcoins worth $27 million.

The government says much of Tylerb’s cryptocurrency wealth was the result of successful SIM-swapping attacks, wherein 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.

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.

Prosecutors allege Tylerb worked closely on SIM-swapping attacks with Noah Michael Urban, another alleged Scattered Spider member from Palm Coast, Fla. who went by the handles “Sosa,” “Elijah,” and “Kingbob.”

Sosa was known to be a top member of the broader cybercriminal community online known as “The Com,” wherein hackers boast loudly about high-profile exploits and hacks 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 networks.

In January 2024, KrebsOnSecurity broke the news that Urban had been arrested in Florida in connection with multiple SIM-swapping attacks. That story noted that Sosa’s alter ego Kingbob routinely targeted people in the recording industry to steal and share “grails,” a slang term used to describe unreleased music recordings from popular artists.

FBI investigators identified a fourth alleged member of the conspiracy – Ahmed Hossam Eldin Elbadawy, 23, of College Station, Texas — after he used a portion of cryptocurrency funds stolen from a victim company to pay for an account used to register phishing domains.

The indictment unsealed Wednesday alleges Elbadawy controlled a number of cryptocurrency accounts used to receive stolen funds, along with another Texas man — Evans Onyeaka Osiebo, 20, of Dallas.

Members of Scattered Spider are reputed to have been involved in a September 2023 ransomware attack against the MGM Resorts hotel chain that quickly brought multiple MGM casinos to a standstill. In September 2024, KrebsOnSecurity reported that a 17-year-old from the United Kingdom was arrested last year by U.K. police as part of an FBI investigation into the MGM hack.

Evans, Elbadawy, Osiebo and Urban were all charged with one count of conspiracy to commit wire fraud, one count of conspiracy, and one count of aggravated identity theft. Buchanan, who is named as an indicted co-conspirator, was charged with conspiracy to commit wire fraud, conspiracy, wire fraud, and aggravated identity theft.

A Justice Department press release states that if convicted, each defendant would face a statutory maximum sentence of 20 years in federal prison for conspiracy to commit wire fraud, up to five years in federal prison for the conspiracy count, and a mandatory two-year consecutive prison sentence for aggravated identity theft. Buchanan would face up to 20 years in prison for the wire fraud count as well.

Canadian Man Arrested in Snowflake Data Extortions

A 25-year-old man in Ontario, Canada has been arrested for allegedly stealing data from and extorting more than 160 companies that used the cloud data service Snowflake.

On October 30, Canadian authorities arrested Alexander Moucka, a.k.a. Connor Riley Moucka of Kitchener, Ontario, on a provisional arrest warrant from the United States. Bloomberg first reported Moucka’s alleged ties to the Snowflake hacks on Monday.

At the end of 2023, malicious hackers learned that many large companies had uploaded huge volumes of sensitive customer data to Snowflake accounts that were protected with little more than a username and password (no multi-factor authentication required). After scouring darknet markets for stolen Snowflake account credentials, the hackers began raiding the data storage repositories used by some of the world’s largest corporations.

Among those 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 of its customers. Wired.com reported in July that AT&T paid a hacker $370,000 to delete stolen phone records.

A report on the extortion attacks 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 Snowflake customers were relieved of data, including TicketMaster, Lending Tree, Advance Auto Parts and Neiman Marcus.

Moucka is alleged to have used the hacker handles Judische and Waifu, among many others. These monikers correspond to a prolific cybercriminal whose exploits were the subject of a recent story published here about the overlap between Western, English-speaking cybercriminals and extremist groups that harass and extort minors into harming themselves or others.

On May 2, 2024, 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.

404 Media reports that at a court hearing in Ontario this morning, Moucka called in from a prison phone and said he was seeking legal aid to hire an attorney.

TELECOM DOMINOES

Mandiant has attributed the Snowflake compromises to a group it calls “UNC5537,” with members based in North America and Turkey. Sources close to the investigation 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.

Update: The Justice Department has unsealed an indictment (PDF) against Moucka and Binns, charging them with one count of conspiracy; 10 counts of wire fraud; four counts of computer fraud and abuse; two counts of extortion in relation to computer fraud; and two counts aggravated identity theft.

In a statement on Moucka’s arrest, Mandiant said UNC5537 aka Alexander ‘Connor’ Moucka has proven to be one of the most consequential threat actors of 2024.

“In April 2024, UNC5537 launched a campaign, systematically compromising misconfigured SaaS instances across over a hundred organizations,” wrote Austin Larsen, Mandiant’s senior threat analyst. “The operation, which left organizations reeling from significant data loss and extortion attempts, highlighted the alarming scale of harm an individual can cause using off-the-shelf tools.”

Sources involved in the investigation said UNC5537 has focused on hacking into telecommunications companies around the world. Those sources told KrebsOnSecurity that Binns and Judische are suspected of stealing data from India’s largest state-run telecommunications firm Bharat Sanchar Nigam Ltd (BNSL), and that the duo even bragged about being able to intercept or divert phone calls and text messages for a large portion of the population of India.

Judische appears to have outsourced the sale of databases from victim companies who refuse to pay, delegating some of that work to a cybercriminal who uses the nickname Kiberphant0m on multiple forums. In late May 2024, Kiberphant0m began advertising the sale of hundreds of gigabytes of data stolen from BSNL.

“Information is worth several million dollars but I’m selling for pretty cheap,” Kiberphant0m wrote of the BSNL data in a post on the English-language cybercrime community Breach Forums. “Negotiate a deal in Telegram.”

Also in May 2024, Kiberphant0m took to the Russian-language hacking forum XSS to sell more than 250 gigabytes of data stolen from an unnamed mobile telecom provider in Asia, including a database of all active customers and software allowing the sending of text messages to all customers.

On September 3, 2024, Kiberphant0m posted a sales thread on XSS titled “Selling American Telecom Access (100B+ Revenue).” Kiberphant0m’s asking price of $200,000 was apparently too high because they reposted the sales thread on Breach Forums a month later, with a headline that more clearly explained the data was stolen from Verizon‘s “push-to-talk” (PTT) customers — primarily U.S. government agencies and first responders.

404Media reported recently that the breach does not appear to impact the main consumer Verizon network. Rather, the hackers broke into a third party provider and stole data on Verizon’s PTT systems, which are a separate product marketed towards public sector agencies, enterprises, and small businesses to communicate internally.

INTERVIEW WITH JUDISCHE

Investigators say Moucka shared a home in Kitchener with other tenants, but not his family. His mother was born in Chechnya, and he speaks Russian in addition to French and English. Moucka’s father died of a drug overdose at age 26, when the defendant was roughly five years old.

A person claiming to be Judische began communicating with this author more than three months ago on Signal after KrebsOnSecurity started asking around about hacker nicknames previously used by Judische over the years.

Judische admitted to stealing and ransoming data from Snowflake customers, but he said he’s not interested in selling the information, and that others have done this with some of the data sets he stole.

“I’m not really someone that sells data unless it’s crypto [databases] or credit cards because they’re the only thing I can find buyers for that actually have money for the data,” Judische told KrebsOnSecurity. “The rest is just ransom.”

Judische has sent this reporter dozens of unsolicited and often profane messages from several different Signal accounts, all of which claimed to be an anonymous tipster sharing different identifying details for Judische. This appears to have been an elaborate effort by Judische to “detrace” his movements online and muddy the waters about his identity.

Judische frequently claimed he had unparalleled “opsec” or operational security, a term that refers to the ability to compartmentalize and obfuscate one’s tracks online. In an effort to show he was one step ahead of investigators, Judische shared information indicating someone had given him a Mandiant researcher’s assessment of who and where they thought he was. Mandiant says those were discussion points shared with select reporters in advance of the researcher’s recent talk at the LabsCon security conference.

But in a conversation with KrebsOnSecurity on October 26, Judische acknowledged it was likely that the authorities were closing in on him, and said he would seriously answer certain questions about his personal life.

“They’re coming after me for sure,” he said.

In several previous conversations, Judische referenced suffering from an unspecified personality disorder, and when pressed said he has a condition called “schizotypal personality disorder” (STPD).

According to the Cleveland Clinic, schizotypal personality disorder is marked by a consistent pattern of intense discomfort with relationships and social interactions: “People with STPD have unusual thoughts, speech and behaviors, which usually hinder their ability to form and maintain relationships.”

Judische said he was prescribed medication for his psychological issues, but that he doesn’t take his meds. Which might explain why he never leaves his home.

“I never go outside,” Judische allowed. “I’ve never had a friend or true relationship not online nor in person. I see people as vehicles to achieve my ends no matter how friendly I may seem on the surface, which you can see by how fast I discard people who are loyal or [that] I’ve known a long time.”

Judische later admitted he doesn’t have an official STPD diagnosis from a physician, but said he knows that he exhibits all the signs of someone with this condition.

“I can’t actually get diagnosed with that either,” Judische shared. “Most countries put you on lists and restrict you from certain things if you have it.”

Asked whether he has always lived at his current residence, Judische replied that he had to leave his hometown for his own safety.

“I can’t live safely where I’m from without getting robbed or arrested,” he said, without offering more details.

A source familiar with the investigation said Moucka previously lived in Quebec, which he allegedly fled after being charged with harassing others on the social network Discord.

Judische claims to have made at least $4 million in his Snowflake extortions. Judische said he and others frequently targeted business process outsourcing (BPO) companies, staffing firms that handle customer service for a wide range of organizations. They also went after managed service providers (MSPs) that oversee IT support and security for multiple companies, he claimed.

“Snowflake isn’t even the biggest BPO/MSP multi-company dataset on our networks, but what’s been exfiltrated from them is well over 100TB,” Judische bragged. “Only ones that don’t pay get disclosed (unless they disclose it themselves). A lot of them don’t even do their SEC filing and just pay us to fuck off.”

INTEL SECRETS

The other half of UNC5537 — 24-year-old John Erin Binns — was arrested in Turkey in late May 2024, and currently resides in a Turkish prison. However, it is unclear if Binns faces any immediate threat of extradition to the United States, where he is currently wanted on criminal hacking charges tied to the 2021 breach at T-Mobile.

A person familiar with the investigation said Binns’s application for Turkish citizenship was inexplicably approved after his incarceration, leading to speculation that Binns may have bought his way out of a sticky legal situation.

Under the Turkish constitution, a Turkish citizen cannot be extradited to a foreign state. Turkey has been criticized for its “golden passport” program, which provides citizenship and sanctuary for anyone willing to pay several hundred thousand dollars.

Binns’s alleged hacker alter egos — “IRDev” and “IntelSecrets” — were at once feared and revered on several cybercrime-focused Telegram communities, because he was known to possess a powerful weapon: A massive botnet. From reviewing the Telegram channels Binns frequented, we can see that others in those communities — including Judische — heavily relied on Binns and his botnet for a variety of cybercriminal purposes.

The IntelSecrets nickname corresponds to an individual who has claimed responsibility for modifying the source code for the Mirai “Internet of Things” botnet to create a variant known as “Satori,” and supplying it to others who used it for criminal gain and were later caught and prosecuted.

Since 2020, Binns has filed a flood of lawsuits naming various federal law enforcement officers and agencies — including the FBI, the CIA, and the U.S. Special Operations Command (PDF), demanding that the government turn over information collected about him and seeking restitution for his alleged kidnapping at the hands of the CIA.

Binns claims he was kidnapped in Turkey and subjected to various forms of psychological and physical torture. According to Binns, the U.S. Central Intelligence Agency (CIA) falsely told their counterparts in Turkey that he was a supporter or member of the Islamic State (ISIS), a claim he says led to his detention and torture by the Turkish authorities.

However, in a 2020 lawsuit he filed against the CIA, Binns himself acknowledged having visited a previously ISIS-controlled area of Syria prior to moving to Turkey in 2017.

Sources familiar with the investigation told KrebsOnSecurity that Binns was so paranoid about possible surveillance on him by American and Turkish intelligence agencies that his erratic behavior and online communications actually brought about the very government snooping that he feared.

In several online chats in late 2023 on Discord, IRDev lamented being lured into a law enforcement sting operation after trying to buy a rocket launcher online. A person close to the investigation confirmed that at the beginning of 2023, IRDev began making earnest inquiries about how to purchase a Stinger, an American-made portable weapon that operates as an infrared surface-to-air missile.

Sources told KrebsOnSecurity Binns’ repeated efforts to purchase the projectile earned him multiple visits from the Turkish authorities, who were justifiably curious why he kept seeking to acquire such a powerful weapon.

WAIFU

A careful study of Judische’s postings on Telegram and Discord since 2019 shows this user is more widely known under the nickname “Waifu,” a moniker that corresponds to one of the more accomplished “SIM swappers” in the English-language cybercrime community over the years.

SIM swapping involves phishing, tricking or bribing mobile phone company employees for credentials needed to redirect a target’s mobile phone number to a device the attackers control — allowing thieves to intercept incoming text messages and phone calls.

Several SIM-swapping 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 list has long included Waifu on a roster of hackers for a group that called itself “Beige.”

The term “Beige Group” came up in reporting on two stories published here in 2020. The first was in an August 2020 piece called Voice Phishers Targeting Corporate VPNs, which warned that the COVID-19 epidemic had brought a wave of targeted voice phishing attacks that tried to trick work-at-home employees into providing access to their employers’ networks. Frequent targets of the Beige group included employees at numerous top U.S. banks, ISPs, and mobile phone providers.

The second time Beige Group was mentioned by sources was in reporting on 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. Other frequent targets of the Beige group included employees at numerous top U.S. banks, ISPs, and mobile phone providers.

Judische’s various Telegram identities have long claimed involvement in the 2020 GoDaddy breach, and he didn’t deny his alleged role when asked directly. Judische said he prefers voice phishing or “vishing” attacks that result in the target installing data-stealing malware, as opposed to tricking the user into entering their username, password and one-time code.

“Most of my ops involve malware [because] credential access burns too fast,” Judische explained.

CRACKDOWN ON HARM GROUPS?

The Telegram channels that the Judische/Waifu accounts frequented over the years show this user divided their time between posting in channels dedicated to financial cybercrime, and harassing and stalking others in harm communities like Leak Society and Court.

Both of these Telegram communities are known for victimizing children through coordinated online campaigns of extortion, doxing, swatting and harassment. People affiliated with harm groups like Court and Leak Society 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.”

Some of the largest such known groups include those that go by the names 764, CVLT, Kaskar, 7997, 8884, 2992, 6996, 555, Slit Town, 545, 404, NMK, 303, and H3ll.

On the various cybercrime-oriented channels Judische frequented, he often lied about his or others’ involvement in various breaches. But Judische also at times shared nuggets of truth about his past, particularly when discussing the early history and membership of specific Telegram- and Discord-based cybercrime and harm groups.

Judische claimed in multiple chats, including on Leak Society and Court, that they were an early member of the Atomwaffen Division (AWD), a white supremacy group whose members are suspected of having committed multiple murders in the U.S. since 2017.

In 2019, KrebsOnSecurity exposed how a loose-knit group of neo-Nazis, some of whom were affiliated with AWD, had doxed and/or swatted nearly three dozen journalists at a range of media publications. Swatting involves communicating a false police report of a bomb threat or hostage situation and tricking authorities into sending a heavily armed police response to a targeted address.

Judsiche also told a fellow denizen of Court that years ago he was active in an older harm community called “RapeLash,” a truly vile Discord server known for attracting Atomwaffen members. A 2018 retrospective on RapeLash posted to the now defunct neo-Nazi forum Fascist Forge explains that RapeLash was awash in gory, violent images and child pornography.

A Fascist Forge member named “Huddy” recalled that RapeLash was the third incarnation of an extremist community also known as “FashWave,” short for Fascist Wave.

“I have no real knowledge of what happened with the intermediary phase known as ‘FashWave 2.0,’ but FashWave 3.0 houses multiple known Satanists and other degenerates connected with AWD, one of which got arrested on possession of child pornography charges, last I heard,” Huddy shared.

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.

Allison Nixon is chief research officer with the New York-based cybersecurity firm Unit 221B. Nixon is among several researchers who have faced harassment and specific threats of physical violence from Judische.

Nixon said Judische is likely to argue in court that his self-described psychological disorder(s) should somehow excuse his long career in cybercrime and in harming others.

“They ran a misinformation campaign in a sloppy attempt to cover up the hacking campaign,” Nixon said of Judische. “Coverups are an acknowledgment of guilt, which will undermine a mental illness defense in court. We expect that violent hackers from the [cybercrime community] will experience increasingly harsh sentences as the crackdown continues.”

Lamborghini Carjackers Lured by $243M Cyberheist

The parents of a 19-year-old Connecticut honors student accused of taking part in a $243 million cryptocurrency heist in August were carjacked a week later — while out house-hunting in a brand new Lamborghini. Prosecutors say the couple was beaten and briefly kidnapped by six young men who traveled from Florida as part of a botched plan to hold the parents for ransom.

Late in the afternoon of Aug. 25, 2024 in Danbury, Ct., a married couple in their 50s pulled up to a gated community in a new Lamborghini Urus (investigators say the sports car still had temporary tags) when they were intentionally rear-ended by a Honda Civic.

A witness told police they saw three men exit a van that was following the Honda, and said the men began assaulting the couple and forcing them into the van. Local police officers spotted the van speeding from the scene and pursued it, only to find the vehicle crashed and abandoned a short distance away.

Inside the disabled van the police found the couple with their hands and feet bound in duct tape, the man visibly bruised after being assaulted with a baseball bat. Danbury police soon reported arresting six suspects in the kidnapping, all men aged 18-26 from Florida. They also recovered the abandoned Lamborghini from a wooded area.

A criminal complaint (PDF) filed on Sept. 24 against the six men does not name the victims, referring to them only as a married couple from Danbury with the initials R.C. and S.C. But prosecutors in Connecticut said they were targeted “because the co-conspirators believed the victims’ son had access to significant amounts of digital currency.”

What made the Miami men so convinced R.C. and S.C.’s son was loaded with cryptocurrency? Approximately one week earlier, on Aug. 19, a group of cybercriminals that allegedly included the couple’s son executed a sophisticated phone-based social engineering attack in which they stole $243 million worth of cryptocurrency from a victim in Washington, D.C.

That’s according to ZachXBT, a frequently cited crypto crime investigator who published a lengthy thread that broke down how the theft was carried out and ultimately exposed by the perpetrators themselves.

ZachXBT’s post included a screen recording of a Discord chat session made by one of the participants to the $243 million robbery, noting that two of the people involved managed to leak the username of the Microsoft Windows PCs they were using to participate in the chat.

One of the usernames leaked during the chat was Veer Chetal. According to ZachXBT, that name corresponds to a 19-year-old from Danbury who allegedly goes by the nickname “Wiz,” although in the leaked video footage he allegedly used the handle “Swag.”  Swag was reportedly involved in executing the early stages of the crypto heist — gaining access to the victim’s Gmail and iCloud accounts.

The same day ZachXBT published his findings, a criminal indictment was issued in Washington D.C. charging two of the men he named as involved in the heist. Prosecutors allege Malone “Greavys” Lam, 20, of Miami and Los Angeles, and Jeandiel “Box” Serrano, 21, of Los Angeles conspired to steal and launder over $230 million in cryptocurrency from a victim in Washington, D.C. The indictment alleges Lam and Serrano were helped by other unnamed co-conspirators.

“Lam and Serrano then allegedly spent the laundered cryptocurrency proceeds on international travel, nightclubs, luxury automobiles, watches, jewelry, designer handbags, and rental homes in Los Angeles and Miami,” reads a press release from the U.S. Department of Justice.

By tracing the flow of funds stolen in the heist, ZachXBT concluded that Wiz received a large percentage from the theft, noting that “additional comfort [in naming him as involved] was gained as throughout multiple recordings accomplices refer to him as ‘Veer’ on audio and in chats.”

“A cluster of [cryptocurrency] addresses tied to both Box/Wiz received $41M+ from two exchanges over the past few weeks primarily flowing to luxury goods brokers to purchase cars, watches, jewelry, and designer clothes,” ZachXBT wrote.

KrebsOnSecurity sought comment from Veer Chetal, and from his parents — Radhika Chetal and Suchil Chetal. This story will be updated in the event that anyone representing the Chetal family responds. Veer Chetal has not been publicly charged with any crime.

According to a news brief published by a private Catholic high school in Danbury that Veer Chetal attended, in 2022 he successfully completed Harvard’s Future Lawyers Program, a “unique pre-professional program where students, guided by qualified Harvard undergraduate instructors, learn how to read and build a case, how to write position papers, and how to navigate a path to law school.” A November 2022 story at patch.com quoted Veer Chetal (class of 2024) crediting the Harvard program with his decision to pursue a career in law.

It remains unclear which Chetal family member acquired the 2023 Lamborghini Urus, which has a starting price of around $233,000. Sushil Chetal’s LinkedIn profile says he is a vice president at the investment bank Morgan Stanley.

It is clear that other alleged co-conspirators to the $243 million heist displayed a conspicuous consumption of wealth following the date of the heist. ZachXBT’s post chronicled Malone’s flashy lifestyle, in which he allegedly used the stolen money to purchase more than 10 vehicles, rent palatial properties, travel with friends on chartered jets, and spend between $250,000 and $500,000 a night at clubs in Los Angeles and Miami.

WSVN-TV in Miami covered an FBI raid of a large rented waterfront home around the time Malone and Serrano were arrested. The news station interviewed a neighbor of the home’s occupants, who reported a recent large party at the residence wherein the street was lined with high-end luxury vehicles — all of them with temporary paper tags.

ZachXBT unearthed a video showing a person identified as Wiz at a Miami nightclub earlier this year, wherein they could be seen dancing to the crowd’s chants while holding an illuminated sign with the message, “I win it all.”

It appears that all of the suspects in the cyber heist (and at least some of the alleged carjackers) are members of The Com, an archipelago of crime-focused chat communities which collectively functions as a kind of distributed cybercriminal social network that facilitates instant collaboration.

As documented in last month’s deep dive on top Com members,  The Com is also a place where cybercriminals go to boast about their exploits and standing within the community, or to knock others down a peg or two. Prominent Com members are endlessly 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 and rob victims for financial gain, members of The Com are trying to wrest stolen money from their cybercriminal rivals — often in ways that spill over into physical violence in the real world.

One of the six Miami-area men arrested in the carjacking and extortion plot gone awry — Reynaldo “Rey” Diaz — was shot twice while parked in his bright yellow Corvette in Miami’s design district in 2022. In an interview with a local NBC television station, Diaz said he was probably targeted for the jewelry he was wearing, which he described as “pretty expensive.”

KrebsOnSecurity has learned Diaz also went by the alias “Pantic” on Telegram chat channels dedicated to stealing cryptocurrencies. Pantic was known for participating in several much smaller cyber heists in the past, and spending most of his cut on designer clothes and jewelry.

Earlier this year, Diaz was “doxed,” or publicly outed as Pantic, with his personal and family information posted on a harassment and extortion channel frequented by members of The Com. The reason cited for Pantic’s doxing was widely corroborated by multiple Com members: Pantic had inexplicably robbed two close friends at gunpoint, one of whom recently died of a drug overdose.

Government prosecutors say the brazen daylight carjacking was paid for and organized by 23-year-old Miami resident Angel “Chi Chi” Borrero. In 2022, Borrero was arrested in Miami for aggravated assault with a deadly weapon.

The six Miami men face charges including first-degree assault, kidnapping and reckless endangerment, and five of them are being held on a $1 million bond. One suspect is also charged with reckless driving, engaging police in pursuit and evading responsibility; his bond was set at $2 million. Lam and Serrano are each charged with conspiracy to commit wire fraud and conspiracy to launder money.

Cybercriminals hail from all walks of life and income levels, but some of the more accomplished cryptocurrency thieves also tend to be among the more privileged, and from relatively well-off families. In other words, these individuals aren’t stealing to put food on the table: They’re doing it so they can amass all the trappings of instant wealth, and so they can boast about their crimes to others on The Com.

There is also a penchant among this crowd to call attention to their activities in conspicuous ways that hasten their arrest and criminal charging. In many ways, the story arc of the young men allegedly involved in the $243 million heist tracks closely to that of Joel Ortiz, a valedictorian who was sentenced in 2019 to 10 years in prison for stealing more than $5 million in cryptocurrencies.

Ortiz famously posted videos of himself and co-conspirators chartering flights and partying it up at LA nightclubs, with scantily clad women waving giant placards bearing their “OG” usernames — highly-prized, single-letter social media accounts that they’d stolen or purchased stolen from others.

Ortiz earned the distinction of being the first person convicted of SIM-swapping, a crime that involves using mobile phone company insiders or compromised employee accounts to transfer a target’s phone number to a mobile device controlled by the attackers. From there, the attacker can intercept any password reset links, and any one-time passcodes sent via SMS or automated voice calls.

But as the mobile carriers seek to make their networks less hospitable to SIM-swappers, and as more financial platforms seek to harden user account security, today’s crypto thieves are finding they don’t need SIM-swaps to steal obscene amounts of cryptocurrency. Not when tricking people over the phone remains such an effective approach.

According to ZachXBT, the crooks responsible for the $243 million theft initially compromised the target’s personal accounts after calling them as Google Support and using a spoofed number. The attackers also spoofed a call from account support representatives at the cryptocurrency exchange Gemini, claiming the target’s account had been hacked.

From there the target was social engineered over the phone into resetting multi-factor authentication and sending Gemini funds to a compromised wallet. ZachXBT says the attackers also convinced the victim to use AnyDesk to share their screen, and in doing so the victim leaked their private keys.

A Single Cloud Compromise Can Feed an Army of AI Sex Bots

Organizations that get relieved of credentials to their cloud environments can quickly find themselves part of a disturbing new trend: Cybercriminals using stolen cloud credentials to operate and resell sexualized AI-powered chat services. Researchers say these illicit chat bots, which use custom jailbreaks to bypass content filtering, often veer into darker role-playing scenarios, including child sexual exploitation and rape.

Researchers at security firm Permiso Security say attacks against generative artificial intelligence (AI) infrastructure like Bedrock from Amazon Web Services (AWS) have increased markedly over the last six months, particularly when someone in the organization accidentally exposes their cloud credentials or key online, such as in a code repository like GitHub.

Investigating the abuse of AWS accounts for several organizations, Permiso found attackers had seized on stolen AWS credentials to interact with the large language models (LLMs) available on Bedrock. But they also soon discovered none of these AWS users had enabled full logging of LLM activity (by default, logs don’t include model prompts and outputs), and thus they lacked any visibility into what attackers were doing with that access.

So Permiso researchers decided to leak their own test AWS key on GitHub, while turning on logging so that they could see exactly what an attacker might ask for, and what the responses might be.

Within minutes, their bait key was scooped up and used in a service that offers AI-powered sex chats online.

“After reviewing the prompts and responses it became clear that the attacker was hosting an AI roleplaying service that leverages common jailbreak techniques to get the models to accept and respond with content that would normally be blocked,” Permiso researchers wrote in a report released today.

“Almost all of the roleplaying was of a sexual nature, with some of the content straying into darker topics such as child sexual abuse,” they continued. “Over the course of two days we saw over 75,000 successful model invocations, almost all of a sexual nature.”

Ian Ahl, senior vice president of threat research at Permiso, said attackers in possession of a working cloud account traditionally have used that access for run-of-the-mill financial cybercrime, such as cryptocurrency mining or spam. But over the past six months, Ahl said, Bedrock has emerged as one of the top targeted cloud services.

“Bad guy hosts a chat service, and subscribers pay them money,” Ahl said of the business model for commandeering Bedrock access to power sex chat bots. “They don’t want to pay for all the prompting that their subscribers are doing, so instead they hijack someone else’s infrastructure.”

Ahl said much of the AI-powered chat conversations initiated by the users of their honeypot AWS key were harmless roleplaying of sexual behavior.

“But a percentage of it is also geared toward very illegal stuff, like child sexual assault fantasies and rapes being played out,” Ahl said. “And these are typically things the large language models won’t be able to talk about.”

AWS’s Bedrock uses large language models from Anthropic, which incorporates a number of technical restrictions aimed at placing certain ethical guardrails on the use of their LLMs. But attackers can evade or “jailbreak” their way out of these restricted settings, usually by asking the AI to imagine itself in an elaborate hypothetical situation under which its normal restrictions might be relaxed or discarded altogether.

“A typical jailbreak will pose a very specific scenario, like you’re a writer who’s doing research for a book, and everyone involved is a consenting adult, even though they often end up chatting about nonconsensual things,” Ahl said.

In June 2024, security experts at Sysdig documented a new attack that leveraged stolen cloud credentials to target ten cloud-hosted LLMs. The attackers Sysdig wrote about gathered cloud credentials through a known security vulnerability, but the researchers also found the attackers sold LLM access to other cybercriminals while sticking the cloud account owner with an astronomical bill.

“Once initial access was obtained, they exfiltrated cloud credentials and gained access to the cloud environment, where they attempted to access local LLM models hosted by cloud providers: in this instance, a local Claude (v2/v3) LLM model from Anthropic was targeted,” Sysdig researchers wrote. “If undiscovered, this type of attack could result in over $46,000 of LLM consumption costs per day for the victim.”

Ahl said it’s not certain who is responsible for operating and selling these sex chat services, but Permiso suspects the activity may be tied to a platform cheekily named “chub[.]ai,” which offers a broad selection of pre-made AI characters with whom users can strike up a conversation. Permiso said almost every character name from the prompts they captured in their honeypot could be found at Chub.

Chub offers free registration, via its website or a mobile app. But after a few minutes of chatting with their newfound AI friends, users are asked to purchase a subscription. The site’s homepage features a banner at the top that reads: “Banned from OpenAI? Get unmetered access to uncensored alternatives for as little as $5 a month.”

Until late last week Chub offered a wide selection of characters in a category called “NSFL” or Not Safe for Life, a term meant to describe content that is disturbing or nauseating to the point of being emotionally scarring.

Fortune profiled Chub AI in a January 2024 story that described the service as a virtual brothel advertised by illustrated girls in spaghetti strap dresses who promise a chat-based “world without feminism,” where “girls offer sexual services.” From that piece:

Chub AI offers more than 500 such scenarios, and a growing number of other sites are enabling similar AI-powered child pornographic role-play. They are part of a broader uncensored AI economy that, according to Fortune’s interviews with 18 AI developers and founders, was spurred first by OpenAI and then accelerated by Meta’s release of its open-source Llama tool.

Fortune says Chub is run by someone using the handle “Lore,” who said they launched the service to help others evade content restrictions on AI platforms. Chub charges fees starting at $5 a month to use the new chatbots, and the founder told Fortune the site had generated more than $1 million in annualized revenue.

KrebsOnSecurity sought comment about Permiso’s research from AWS, which initially seemed to downplay the seriousness of the researchers’ findings. The company noted that AWS employs automated systems that will alert customers if their credentials or keys are found exposed online.

AWS explained that when a key or credential pair is flagged as exposed, it is then restricted to limit the amount of abuse that attackers can potentially commit with that access. For example, flagged credentials can’t be used to create or modify authorized accounts, or spin up new cloud resources.

Ahl said Permiso did indeed receive multiple alerts from AWS about their exposed key, including one that warned their account may have been used by an unauthorized party. But they said the restrictions AWS placed on the exposed key did nothing to stop the attackers from using it to abuse Bedrock services.

Sometime in the past few days, however, AWS responded by including Bedrock in the list of services that will be quarantined in the event an AWS key or credential pair is found compromised or exposed online. AWS confirmed that Bedrock was a new addition to its quarantine procedures.

Additionally, not long after KrebsOnSecurity began reporting this story, Chub’s website removed its NSFL section. It also appears to have removed cached copies of the site from the Wayback Machine at archive.org. Still, Permiso found that Chub’s user stats page shows the site has more than 3,000 AI conversation bots with the NSFL tag, and that 2,113 accounts were following the NSFL tag.

Permiso said their entire two-day experiment generated a $3,500 bill from AWS. Most of that cost was tied to the 75,000 LLM invocations caused by the sex chat service that hijacked their key.

Paradoxically, Permiso found that while enabling these logs is the only way to know for sure how crooks might be using a stolen key, the cybercriminals who are reselling stolen or exposed AWS credentials for sex chats have started including programmatic checks in their code to ensure they aren’t using AWS keys that have prompt logging enabled.

“Enabling logging is actually a deterrent to these attackers because they are immediately checking to see if you have logging on,” Ahl said. “At least some of these guys will totally ignore those accounts, because they don’t want anyone to see what they’re doing.”

In a statement shared with KrebsOnSecurity, AWS said its services are operating securely, as designed, and that no customer action is needed. Here is their statement:

“AWS services are operating securely, as designed, and no customer action is needed. The researchers devised a testing scenario that deliberately disregarded security best practices to test what may happen in a very specific scenario. No customers were put at risk. To carry out this research, security researchers ignored fundamental security best practices and publicly shared an access key on the internet to observe what would happen.”

“AWS, nonetheless, quickly and automatically identified the exposure and notified the researchers, who opted not to take action. We then identified suspected compromised activity and took additional action to further restrict the account, which stopped this abuse. We recommend customers follow security best practices, such as protecting their access keys and avoiding the use of long-term keys to the extent possible. We thank Permiso Security for engaging AWS Security.”

AWS said customers can configure model invocation logging to collect Bedrock invocation logs, model input data, and model output data for all invocations in the AWS account used in Amazon Bedrock. Customers can also use CloudTrail to monitor Amazon Bedrock API calls.

The company said AWS customers also can use services such as GuardDuty to detect potential security concerns and Billing Alarms to provide notifications of abnormal billing activity. Finally, AWS Cost Explorer is intended to give customers a way to visualize and manage Bedrock costs and usage over time.

Anthropic told KrebsOnSecurity it is always working on novel techniques to make its models more resistant to jailbreaks.

“We remain committed to implementing strict policies and advanced techniques to protect users, as well as publishing our own research so that other AI developers can learn from it,” Anthropic said in an emailed statement. “We appreciate the research community’s efforts in highlighting potential vulnerabilities.”

Anthropic said it uses feedback from child safety experts at Thorn around signals often seen in child grooming to update its classifiers, enhance its usage policies, fine tune its models, and incorporate those signals into testing of future models.

Update: 5:01 p.m. ET: Chub has issued a statement saying they are only hosting the role-playing characters, and that the LLMs they use run on their own infrastructure.

“Our own LLMs run on our own infrastructure,” Chub wrote in an emailed statement. “Any individuals participating in such attacks can use any number of UIs that allow user-supplied keys to connect to third-party APIs. We do not participate in, enable or condone any illegal activity whatsoever.”

Crooked Cops, Stolen Laptops & the Ghost of UGNazi

A California man accused of failing to pay taxes on tens of millions of dollars allegedly earned from cybercrime also paid local police officers hundreds of thousands of dollars to help him extort, intimidate and silence rivals and former business partners, the government alleges. KrebsOnSecurity has learned that many of the man’s alleged targets were members of UGNazi, a hacker group behind multiple high-profile breaches and cyberattacks back in 2012.

A federal complaint (PDF) filed last week said the Federal Bureau of Investigation (FBI) has been investigating Los Angeles resident Adam Iza. Also known as “Assad Faiq” and “The Godfather,” Iza is the founder of a cryptocurrency investment platform called Zort that advertised the ability to make smart trades based on artificial intelligence technology.

But the feds say investors in Zort soon lost their shorts, after Iza and his girlfriend began spending those investments on Lamborghinis, expensive jewelry, vacations, a $28 million home in Bel Air, even cosmetic surgery to extend the length of his legs.

The complaint states the FBI started looking at Iza after receiving multiple reports that he had on his payroll several active deputies with the Los Angeles Sheriff’s Department (LASD). Iza’s attorney did not immediately respond to requests for comment.

The complaint cites a letter from an attorney for a victim referenced only as “E.Z.,” who was seeking help related to an extortion and robbery allegedly committed by Iza. The government says that in March 2022, three men showed up at E.Z.’s home, and tried to steal his laptop in an effort to gain access to E.Z. cryptocurrency holdings online. A police report referenced in the complaint says three intruders were scared off when E.Z. fired several handgun rounds in the direction of his assailants.

The FBI later obtained a copy of a search warrant executed by LASD deputies in January 2022 for GPS location information on a phone belonging to E.Z., which shows an LASD deputy unlawfully added E.Z.’s mobile number to a list of those associated with an unrelated firearms investigation.

“Damn my guy actually filed the warrant,” Iza allegedly texted someone after the location warrant was entered. “That’s some serious shit to do for someone….risking a 24 years career. I pay him 280k a month for complete resources. They’re active-duty.”

The FBI alleges LASD officers had on several previous occasions tried to kidnap and extort E.Z. at Iza’s behest. The complaint references a November 2021 incident wherein Iza and E.Z. were in a car together when Iza asked to stop and get snacks at a convenience store. While they were still standing next to the car, a van with several armed LASD deputies showed up and tried to force E.Z. to hand over his phone. E.Z. escaped unharmed, and alerted 911.

E.Z. appears to be short for Enzo Zelocchi, a self-described “actor” who was featured in an ABC News story about a home invasion in Los Angeles around that same time as the March 2022 home invasion, in which Zelocchi is quoted as saying at least two men tried to rob him at gunpoint (we’ll revisit Zelocchi’s acting credits in a moment).

The criminal complaint makes frequent references to a co-conspirator of Iza (“CC-1”) — his girlfriend at the time — who allegedly helped Iza run his businesses and spend the millions plunked down by Zort investors. We know what E.Z. stands for because Iza’s girlfriend then was a woman named Iris Au, and in November 2022 she sued Zelocchi for allegedly stealing Iza’s laptop.

The complaint says Iza also harassed a man identified only as T.W., and refers to T.W. as one of two Americans currently incarcerated in the Philippines for murder. In December 2018, a then 21-year-old Troy Woody Jr. was arrested in Manila after he was spotted dumping the body of his dead girlfriend Tomi Masters into a local river.

Woody is accused of murdering Masters with the help of his best friend and roommate at the time: Mir Islam, a.k.a. “JoshTheGod,” referred to in the Iza complaint as “M.I.” Islam and Woody were both core members of UGNazi, a hacker collective that sprang up in 2012 and claimed credit for hacking and attacking a number of high-profile websites.

In June 2016, Islam was sentenced to a year in prison for an impressive array of crimes, including stalking people online and posting their personal data on the Internet. Islam also pleaded guilty to reporting dozens of phony bomb threats and fake hostage situations at the homes of celebrities and public officials (Islam participated in a swatting attack against this author in 2013).

In December 2022, Troy Woody Jr. sued Iza, Zelocchi and Zort, alleging (PDF) Iza and Zelocchi were involved in a 2018 home invasion at his residence, wherein Woody claimed his assailants stole laptops and phones containing more than $200 million in cryptocurrencies.

Woody’s complaint states that Masters also was present during his 2018 home invasion, as was another core UGNazi member: Eric “CosmoTheGod” Taylor. CosmoTheGod rocketed to Internet infamy in 2013 when he and a number of other hackers set up the Web site exposed[dot]su, which published the address, Social Security numbers and other personal information of public figures, including the former First Lady Michelle Obama, the then-director of the FBI and the U.S. attorney general. The group also swatted many of the people they doxed.

In 2017, Taylor was sentenced to three years probation for participating in multiple swatting attacks, including the one against my home in 2013.

The complaint against Iza says the FBI interviewed Woody in Manila where he is currently incarcerated, and learned that Iza has been harassing him about passwords that would unlock access to cryptocurrencies. The FBI’s complaint leaves open the question of how Woody and Islam got the phones in the first place, but the implication is that Iza may have instigated the harassment by having mobile phones smuggled to the prisoners.

The government suggests its case against Iza was made possible in part thanks to Iza’s propensity for ripping off people who worked for him. The complaint cites information provided by a private investigator identified only as “K.C.,” who said Iza hired him to surveil Zelocchi but ultimately refused to pay him for much of the work.

K.C. stands for Kenneth Childs, who in 2022 sued Iris Au and Zort (PDF) for theft by deception and commercial disparagement, after it became clear his private eye services were being used as part of a scheme by the Zort founders to intimidate and extort others. Childs’ complaint says Iza clawed back tens of thousands of dollars in payments he’d previously made as part of their contract.

The government also included evidence provided by an associate of Iza’s — named only as “R.C.” — who was hired to throw a party at Iza’s home. According to the feds, Iza paid the associate $50,000 to craft the event to his liking, but on the day of the party Iza allegedly told R.C. he was unhappy with the event and demanded half of his money back.

When R.C. balked, Iza allegedly surrounded the man with armed LASD officers, who then extracted the payment by seizing his phone. The government says Iza kept R.C.’s phone and spent the remainder of his bank balance.

The FBI said that after the incident at the party, Iza had his bribed sheriff deputies pull R.C. over and arrest him on phony drug charges. The complaint includes a photo of R.C. being handcuffed by the police, which the feds say Iza sent to R.C. in order to intimidate him even further. The drug charges were later dismissed for lack of evidence.

The government alleges Iza and Au paid the LASD officers using Zelle transfers from accounts tied to two different entities incorporated by one or both of them: Dream Agency and Rise Agency. The complaint further alleges that these two entities were the beneficiaries of a business that sold hacked and phished Facebook advertising accounts, and bribed Facebook employees to unblock ads that violated its terms of service.

The complaint says Iza ran this business with another individual identified only as “T.H.,” and that at some point T.H. had personal problems and checked himself into rehab. T.H. told the FBI that Iza responded by stealing his laptop and turning him in to the government.

KrebsOnSecurity has learned that T.H. in this case is Tassilo Heinrich, a man indicted in 2022 for hacking into the e-commerce platform Shopify, and leaking the user database for Ledger, a company that makes hardware wallets for storing cryptocurrencies.

Heinrich pleaded guilty and was sentenced to time served, three years of supervised release, and ordered to pay restitution to Shopify. Upon his release from custody, Heinrich told the FBI that Iza was still using his account at the public screenshot service Gyazo to document communications regarding his alleged bribing of LASD officers.

Prosecutors say Iza and Au portrayed themselves as glamorous and wealthy individuals who were successful social media influencers, but that most of that was a carefully crafted facade designed to attract investment from cryptocurrency enthusiasts. Meanwhile, the U.K. tabloids reported this summer that Au was dating Davide Sanclimenti, the 2022 co-winner on the dating reality show Love Island.

Recall that we promised to revisit Mr. Zelocchi’s claimed acting credits. Despite being briefly listed on the Internet Movie Data Base (imdb.com) as the most awarded science fiction actor of all time, it’s not clear whether Mr. Zelocchi has starred in any real movies.

Earlier this year, an Internet sleuth on Youtube showed that even though Zelocchi’s IMDB profile has him earning more awards than most other actors on the platform (here he is holding a Youtube top viewership award), Zelocchi is probably better known as the director of the movie once rated the absolute worst sci-fi flick on IMDB: A 2015 work called “Angel’s Apocalypse.” Most of the videos on Zelocchi’s Instagram page appear to be brief clips, some of which look more like a commercial for men’s cologne than scenes from a real movie.

In many ways, the crimes described in this complaint and the various related civil lawsuits would prefigure a disturbing new trend within English-speaking cybercrime communities that has bubbled up in the past few years: The emergence of “violence-as-as-service” offerings that allow cybercriminals to anonymously extort and intimidate their rivals.

Found on certain Telegram channels are solicitations for IRL or “In Real Life” jobs, wherein people hire themselves out as willing to commit a variety of physical attacks in their local geographic area, such as slashing tires, firebombing a home, or tossing a brick through someone’s window.

Many of the cybercriminals in this community have stolen tens of millions of dollars worth of cryptocurrency, and can easily afford to bribe police officers. KrebsOnSecurity would expect to see more of this in the future as young, crypto-rich cybercriminals seek to corrupt people in authority to their advantage.

U.S. Indicts 2 Top Russian Hackers, Sanctions Cryptex

The United States today unveiled sanctions and indictments against the alleged proprietor of Joker’s Stash, a now-defunct cybercrime store that peddled tens of millions of payment cards stolen in some of the largest data breaches of the past decade. The government also indicted and sanctioned a top Russian cybercriminal known as Taleon, whose cryptocurrency exchange Cryptex has evolved into one of Russia’s most active money laundering networks.

The U.S. Department of Justice (DOJ) today unsealed an indictment against a 38-year-old man from Novosibirsk, Russia for allegedly operating Joker’s Stash, an extremely successful carding shop that came online in late 2014. Joker’s sold cards stolen in a steady drip of breaches at U.S. retailers, including Saks Fifth Avenue, Lord and Taylor, Bebe Stores, Hilton Hotels, Jason’s Deli, Whole Foods, Chipotle, Wawa, Sonic Drive-In, the Hy-Vee supermarket chain, Buca Di Beppo, and Dickey’s BBQ.

The government believes the brains behind Joker’s Stash is Timur Kamilevich Shakhmametov, an individual who is listed in Russian incorporation documents as the owner of Arpa Plus, a Novosibirsk company that makes mobile games.

Early in his career (circa 2000) Shakhmametov was known as “v1pee” and was the founder of the Russian hacker group nerf[.]ru, which periodically published hacking tools and exploits for software vulnerabilities.

By 2004, v1pee had adopted the moniker “Vega” on the exclusive Russian language hacking forum Mazafaka, where this user became one of the more reliable vendors of stolen payment cards.

In the years that followed, Vega would cement his reputation as a top carder on other forums, including Verified, DirectConnection, and Carder[.]pro.

Vega also became known as someone who had the inside track on “unlimited cashouts,” a globally coordinated cybercrime scheme in which crooks hack a bank or payment card processor and use cloned cards at cash machines to rapidly withdraw millions of dollars in just a few hours.

“Hi, there is work on d+p, unlimited,” Vega wrote in a private message to another user on Verified in Dec. 2012, referring to “dumps and PINs,” the slang term for stolen debit cards with the corresponding PINs that would allow ATM withdrawals.

Joker’s Stash came online in the wake of several enormous card breaches at retailers like Target and Home Depot, and the resulting glut of inventory had depressed prices for stolen cards. But Joker’s would distinguish itself by catering to high-roller customers — essentially street gangs in the United States that would purchase thousands of stolen payment cards in one go.

Faced with a buyer’s market, Joker’s Stash set themselves apart by focusing on loyalty programs, frequent buyer discounts, money-back guarantees, and just plain good customer service. Big spenders were given access to the most freshly hacked payment cards, and were offered the ability to get free replacement cards if any turned out to be duds.

Joker’s Stash also was unique because it claimed to sell only payment cards that its own hackers had stolen directly from merchants. At the time, card shops typically resold payment cards that were stolen and supplied by many third-party hackers of unknown reliability or reputation.

In January 2021, Joker’s Stash announced it was closing up shop, after European authorities seized a number of servers for the fraud store, and its proprietor came down with the Coronavirus.

A DOJ statement credits the U.S. Secret Service for leading the years-long investigations (the Service’s original mandate was not protecting the president; it was pursuing counterfeiters, and modern-day carders definitely qualify as that). Prosecutors allege Joker’s Stash earned revenues of at least $280 million, but possibly more than $1 billion (the broad range is a consequence of several variables, including the rapid fluctuation in the price of bitcoin and the stolen goods they were peddling).

TALEON

The proprietors of Joker’s Stash may have sold tens of millions of stolen payment cards, but Taleon is by far the bigger fish in this law enforcement action because his various cryptocurrency and cash exchanges have allegedly helped to move billions of dollars into and out of Russia over the past 20 years.

An indictment unsealed today names Taleon as Sergey Sergeevich Ivanov, 44, of Saint Petersburg, Russia. The government says Ivanov, who likely changed his surname from Omelnitskii at some point, laundered money for Joker’s Stash, among many other cybercrime stores.

In a statement today, the Treasury Department said Ivanov has laundered hundreds of millions of dollars’ worth of virtual currency for ransomware actors, initial access brokers, darknet marketplace vendors, and other criminal actors for approximately the last 20 years.

First appearing on Mazafaka in the early 2000s, Taleon was known on the forums as someone who could reliably move large amounts of physical cash. Sources familiar with the investigation said Taleon’s service emerged as one of the few remaining domestic cash delivery services still operating after Russia invaded Ukraine in Feb. 2022.

Taleon set up his service to facilitate transfers between Moscow, St. Petersburg and financial institutions in the West. Taleon’s private messages on some hacker forums have been leaked over the years and indexed by the cyber intelligence platform Intel 471. Those messages indicate Taleon worked on many of the same ATM cashouts as Vegas, so it’s clear the two had an established business relationship well before Joker’s Stash came into being.

Sometime around 2013, Taleon launched a partnership with a money transfer business called pm2btc[.]me. PM2BTC allowed customers to convert funds from the virtual currency Perfect Money (PM) into bitcoin, and then have the balance (minus a processing fee) available on a physical debit card that could be used at ATMs, for shopping online, or at retail stores.

The U.S. government itself set things in motion for Taleon’s nascent cryptocurrency exchange business in 2013 after the DOJ levied money laundering charges against the proprietors of Liberty Reserve, one of the largest virtual currencies in operation at the time.  Liberty Reserve was heavily used by cybercriminals of all stripes. The government said the service had more than a million users worldwide, and laundered in excess of $6 billion in suspected criminal proceeds.

In the days following the takedown of Liberty Reserve, KrebsOnSecurity ran a story that examined discussions across multiple top Russian cybercrime forums about where crooks could feel safe parking their stolen funds. The answer involved Bitcoin, but also Taleon’s new service.

UAPS

Part of the appeal of Taleon’s exchange was that it gave its vetted customers an “application programming interface” or API that made it simple for dodgy online shops selling stolen goods and cybercrime services to accept cryptocurrency deposits from their customers, and to manage payouts to any suppliers and affiliates.

This API is synonymous with a service Taleon and friends operate in the background called UAPS, short for “Universal Anonymous Payment System.” UAPS has gone by several other names including “Pinpays,” and in October 2014 it landed Joker’s Stash as its first big client.

A source with knowledge of the investigation told KrebsOnSecurity that Taleon is a pilot who owns and flies around in his own helicopter.

Ivanov appears to have little to no social media presence, but the 40-year-old woman he lives with in St. Petersburg does, and she has a photo on her Vktontake page that shows the two of them in 2019 flying over Lake Ladoga, a large body of water directly north of St. Petersburg.

BRIANS CLUB

In late 2015, a major competitor to Joker’s Stash emerged using UAPS for its back-end payments: BriansClub. BriansClub sullies this author’s name, photos and reputation to peddle millions of credit and debit cards stolen from merchants in the United States and around the world.

In 2019, someone hacked BriansClub and relieved the fraud shop of more than 26 million stolen payment cards — an estimated one-third of the 87 million payment card accounts that were on sale across all underground shops at that time. An anonymous source shared that card data with KrebsOnSecurity, which ultimately shared it with a consortium of financial institutions that issued most of the cards.

After that incident, the administrator of BriansClub changed the site’s login page so that it featured a copy of my phone bill, Social Security card, and a link to my full credit report [to this day, random cybercriminals confuse Yours Truly with the proprietor of BriansClub].

Alex Holden is founder of the Milwaukee-based cybersecurity firm Hold Security. Holden has long maintained visibility into cryptocurrency transactions made by BriansClub.

Holden said those records show BriansClub sells tens of thousands of dollars worth of stolen credit cards every day, and that in the last two years alone the BriansClub administrator has removed more than $242 million worth of cryptocurrency revenue from the UAPS platform.

Passive domain name system (DNS) records show that in its early days BriansClub shared a server in Lithuania along with just a handful of other domains, including secure.pinpays[.]com, the crime forum Verified, and a slew of carding shops operating under the banner Rescator.

As KrebsOnSecurity detailed in December 2023, the Rescator shops were directly involved in some of the largest payment card breaches of the past decade. Those include the 2013 breach at Target and the 2014 breach at Home Depot, intrusions that exposed more than 100 million payment card records.

CRYPTEX

In early 2018, Taleon and the proprietors of UAPS launched a cryptocurrency exchange called Cryptex[.]net that has emerged as a major mover of ill-gotten crypto coins.

Cryptex has been associated with quite a few ransomware transactions, including the largest known ransomware payment to date. In February 2024, a Fortune 50 ransomware victim paid a record $75 million ransom to a Russian cybercrime group that calls themselves the Dark Angels. A source with knowledge of the investigation said an analysis of that payment shows roughly half of it was processed through Cryptex.

That source provided a screen shot of Cryptex’s sending and receiving exposure as viewed by Chainalysis, a company the U.S. government and many cryptocurrency exchanges rely on to flag transactions associated with suspected money laundering, ransomware payouts, or facilitating payments for darknet websites.

Chainalysis finds that Cryptex has received more than $1.6 billion since its inception, and that this amount is roughly equal to its sending exposure (although the total number of outflows is nearly half of the inflows).

The graphic indicates a great deal of money flowing into Cryptex — roughly a quarter of it — is coming from bitcoin ATMs around the world. Experts say most of those ATM inflows to Cryptex are bitcoin ATM cash deposits from customers of carding websites like BriansClub and Jokers Stash.

The indictments released today do not definitively connect Taleon to Cryptex. However, PM2BTC (which teamed up with Taleon to launch UAPS and Pinpays) and Cryptex have now been sanctioned by the U.S. Department of the Treasury.

Treasury’s Financial Crimes Enforcement Network (FinCEN) levied sanctions today against PM2BTC under a powerful new “Section 9714” authority included in the Combating Russian Money Laundering Act, changes enacted in 2022 to make it easier to target financial entities involved in laundering money for Russia.

Treasury first used this authority last year against Bitzlato, a cryptocurrency exchange operating in Russia that became a money laundering conduit for ransomware attackers and dark market dealers.

THE LAUNDROMAT

An investigation into the corporate entities behind UAPS and Cryptex reveals an organization incorporated in 2012 in Scotland called Orbest Investments LP. Records from the United Kingdom’s business registry show the owners of Orbest Investments are two entities: CS Proxy Solutions CY, and RM Everton Ltd.

Public business records further reveal that CS Proxy Solutions and RM Everton are co-owners of Progate Solutions, a holding company that featured prominently in a June 2017 report from Bellingcat and Transparency International (PDF) on money laundering networks tied to the Kremlin.

“Law enforcement agencies believe that the total amount laundered through this process could be as high as US$80 billion,” the joint report reads. “Although it is not clear where all of this money came from, investigators claim it includes significant amounts of money that were diverted from the Russian treasury and state contracts.”

Their story built on reporting published earlier that year by the Organized Crime and Corruption Project (OCCRP) and Novaya Gazeta, which found that at least US$20.8 billion was secretly moved out of Russia between 2010 and 2014 through a vast money laundering machine comprising over 5,000 legal entities known as “The Laundromat.”

“Using company records, reporters tracked the names of some clients after executives refused to give them out,” the OCCRP report explains. “They found the heavy users of the scheme were rich and powerful Russians who had made their fortunes from dealing with the Russian state.”

Rich Sanders is a blockchain analyst and investigator who advises the law enforcement and intelligence community. Sanders just returned from a three-week sojourn through Ukraine, traveling with Ukrainian soldiers while mapping out dodgy Russian crypto exchanges that are laundering money for narcotics networks operating in the region. Sanders said today’s sanctions by the Treasury Department will likely have an immediate impact on Cryptex and its customers.

“Whenever an entity is sanctioned, the implications on-chain are immense,” Sanders told KrebsOnSecurity. “Regardless of whether an exchange is actually compliant or just virtue signals it, it is the case across the board that exchanges will pay attention to these sanctions.”

“This action shows these payment processors for illicit platforms will get attention eventually,” Sanders continued. “Even if it took way too long in this case, Cryptex knew the majority of their volume was problematic, knew why it was problematic, and did it anyway. And this should be a wake up call for other exchanges that know full well that most of their volume is problematic.”

The U.S. Department of State is offering a reward of up to $10 million each for information leading to the arrests and/or convictions of Shakhmametov and Ivanov. The State announcement says separate rewards of up to $1 million each are being offered for information leading to the identification of other leaders of the Joker’s Stash criminal marketplace (other than Shakhmametov), as well as the identification of other key leaders of the UAPS, PM2BTC, and PinPays transnational criminal groups (other than Ivanov).

Damn-Vulnerable-Drone - An Intentionally Vulnerable Drone Hacking Simulator Based On The Popular ArduPilot/MAVLink Architecture, Providing A Realistic Environment For Hands-On Drone Hacking

The Damn Vulnerable Drone is an intentionally vulnerable drone hacking simulator based on the popular ArduPilot/MAVLink architecture, providing a realistic environment for hands-on drone hacking.

About the Damn Vulnerable Drone

What is the Damn Vulnerable Drone?

The Damn Vulnerable Drone is a virtually simulated environment designed for offensive security professionals to safely learn and practice drone hacking techniques. It simulates real-world ArduPilot & MAVLink drone architectures and vulnerabilities, offering a hands-on experience in exploiting drone systems.

Why was it built?

The Damn Vulnerable Drone aims to enhance offensive security skills within a controlled environment, making it an invaluable tool for intermediate-level security professionals, pentesters, and hacking enthusiasts.

Similar to how pilots utilize flight simulators for training, we can use the Damn Vulnerable Drone simulator to gain in-depth knowledge of real-world drone systems, understand their vulnerabilities, and learn effective methods to exploit them.

The Damn Vulnerable Drone platform is open-source and available at no cost and was specifically designed to address the substantial expenses often linked with drone hardware, hacking tools, and maintenance. Its cost-free nature allows users to immerse themselves in drone hacking without financial concerns. This accessibility makes the Damn Vulnerable Drone a crucial resource for those in the fields of information security and penetration testing, promoting the development of offensive cybersecurity skills in a safe environment.

How does it work?

The Damn Vulnerable Drone platform operates on the principle of Software-in-the-Loop (SITL), a simulation technique that allows users to run drone software as if it were executing on an actual drone, thereby replicating authentic drone behaviors and responses.

ArduPilot's SITL allows for the execution of the drone's firmware within a virtual environment, mimicking the behavior of a real drone without the need for physical hardware. This simulation is further enhanced with Gazebo, a dynamic 3D robotics simulator, which provides a realistic environment and physics engine for the drone to interact with. Together, ArduPilot's SITL and Gazebo lay the foundation for a sophisticated and authentic drone simulation experience.

While the current Damn Vulnerable Drone setup doesn't mirror every drone architecture or configuration, the integrated tactics, techniques and scenarios are broadly applicable across various drone systems, models and communication protocols.

The Dark Nexus Between Harm Groups and ‘The Com’

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 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 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.

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.

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.

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 is the 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 shows the name of the federal agent who testified to it has been blacked out:

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.

James Thomas Andrew McCarty, Charlotte, N.C., and Kya “Chumlul” 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 Peekskill 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 advisory on sexual extortion of minors over the Internet lists a number of potential warning signs that teens may exhibit if they become entangled 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.

Bug Left Some Windows PCs Dangerously Unpatched

Microsoft Corp. today released updates to fix at least 79 security vulnerabilities in its Windows operating systems and related software, including multiple flaws that are already showing up in active attacks. Microsoft also corrected a critical bug that has caused some Windows 10 PCs to remain dangerously unpatched against actively exploited vulnerabilities for several months this year.

By far the most curious security weakness Microsoft disclosed today has the snappy name of CVE-2024-43491, which Microsoft says is a vulnerability that led to the rolling back of fixes for some vulnerabilities affecting “optional components” on certain Windows 10 systems produced in 2015. Those include Windows 10 systems that installed the monthly security update for Windows released in March 2024, or other updates released until August 2024.

Satnam Narang, senior staff research engineer at Tenable, said that while the phrase “exploitation detected” in a Microsoft advisory normally implies the flaw is being exploited by cybercriminals, it appears labeled this way with CVE-2024-43491 because the rollback of fixes reintroduced vulnerabilities that were previously know to be exploited.

“To correct this issue, users need to apply both the September 2024 Servicing Stack Update and the September 2024 Windows Security Updates,” Narang said.

Kev Breen, senior director of threat research at Immersive Labs, said the root cause of CVE-2024-43491 is that on specific versions of Windows 10, the build version numbers that are checked by the update service were not properly handled in the code.

“The notes from Microsoft say that the ‘build version numbers crossed into a range that triggered a code defect’,” Breen said. “The short version is that some versions of Windows 10 with optional components enabled was left in a vulnerable state.”

Zero Day #1 this month is CVE-2024-38226, and it concerns a weakness in Microsoft Publisher, a standalone application included in some versions of Microsoft Office. This flaw lets attackers bypass Microsoft’s “Mark of the Web,” a Windows security feature that marks files downloaded from the Internet as potentially unsafe.

Zero Day #2 is CVE-2024-38217, also a Mark of the Web bypass affecting Office. Both zero-day flaws rely on the target opening a booby-trapped Office file.

Security firm Rapid7 notes that CVE-2024-38217 has been publicly disclosed via an extensive write-up, with exploit code also available on GitHub.

According to Microsoft, CVE-2024-38014, an “elevation of privilege” bug in the Windows Installer, is also being actively exploited.

June’s coverage of Microsoft Patch Tuesday was titled “Recall Edition,” because the big news then was that Microsoft was facing a torrent of criticism from privacy and security experts over “Recall,” a new artificial intelligence (AI) feature of Redmond’s flagship Copilot+ PCs that constantly takes screenshots of whatever users are doing on their computers.

At the time, Microsoft responded by suggesting Recall would no longer be enabled by default. But last week, the software giant clarified that what it really meant was that the ability to disable Recall was a bug/feature in the preview version of Copilot+ that will not be available to Windows customers going forward. Translation: New versions of Windows are shipping with Recall deeply embedded in the operating system.

It’s pretty rich that Microsoft, which already collects an insane amount of information from its customers on a near constant basis, is calling the Recall removal feature a bug, while treating Recall as a desirable feature. Because from where I sit, Recall is a feature nobody asked for that turns Windows into a bug (of the surveillance variety).

When Redmond first responded to critics about Recall, they noted that Recall snapshots never leave the user’s system, and that even if attackers managed to hack a Copilot+ PC they would not be able to exfiltrate on-device Recall data.

But that claim rang hollow after former Microsoft threat analyst Kevin Beaumont detailed on his blog how any user on the system (even a non-administrator) can export Recall data, which is just stored in an SQLite database locally.

As it is apt to do on Microsoft Patch Tuesday, Adobe has released updates to fix security vulnerabilities in a range of products, including Reader and Acrobat, After Effects, Premiere Pro, Illustrator, ColdFusion, Adobe Audition, and Photoshop. Adobe says it is not aware of any exploits in the wild for any of the issues addressed in its updates.

Seeking a more detailed breakdown of the patches released by Microsoft today? Check out the SANS Internet Storm Center’s thorough list. People responsible for administering many systems in an enterprise environment would do well to keep an eye on AskWoody.com, which often has the skinny on any wonky Windows patches that may be causing problems for some users.

As always, if you experience any issues applying this month’s patch batch, consider dropping a note in the comments here about it.

Owners of 1-Time Passcode Theft Service Plead Guilty

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 passcodes 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 that was sent to the user via SMS when the thieves attempted to log in. Any codes shared by the target were 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.

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 months 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.

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.

Notorious Iranian Hackers Have Been Targeting the Space Industry With a New Backdoor

In addition to its long-standing password spraying attacks, Microsoft says Iran-backed hacker group Peach Sandstorm—or APT 33—has developed custom malware dubbed “Tickler.”

How to Protect Your Personal Info

Whether it tags along via a smartphone, laptop, tablet, or wearable, it seems like the internet follows us wherever we go nowadays. Yet there’s something else that follows us around as well — a growing body of personal info that we create while banking, shopping, and simply browsing the internet. And no doubt about it, our info is terrifically valuable.

What makes it so valuable? It’s no exaggeration to say that your personal info is the key to your digital life, along with your financial and civic life as well. Aside from using it to create accounts and logins, it’s further tied to everything from your bank accounts and credit cards to your driver’s license and your tax refund.

Needless to say, your personal info is something that needs protecting, so let’s check out several ways you can do just that.

What is personal info?

What is personal info? It’s info about you that others can use to identify you either directly or indirectly. Thus, that info could identify you on its own. Or it could identify you when it’s linked to other identifiers, like the ones linked with the devices, apps, tools, and protocols you use.

A prime example of direct personal info is your tax ID number because it’s unique and directly tied to your name. Further instances include your facial image to unlock your smartphone, your medical records, your finances, and your phone number because each of these can be easily linked back to you.

Then there are those indirect pieces of personal info that act as helpers. While they might not identify you on their own, a few of them can when they’re added together. These helpers include things like internet protocol addresses, the unique device ID of your smartphone, or other identifiers such as radio frequency identification tags.

You can also find pieces of your personal info in the accounts you use, like your Google to Apple IDs, which can be linked to your name, your email address, and the apps you have. You’ll also find it in the apps you use. For example, there’s personal info in the app you use to map your walks and runs, because the combination of your smartphone’s unique device ID and GPS tracking can be used in conjunction with other info to identify who you are. Not to mention where you typically like to do your 5k hill days. The same goes for messenger apps, which can collect how you interact with others, how often you use the app, and your location info based on your IP address, GPS info, or both.

In all, there’s a cloud of personal info that follows us around as we go about our day online. Some wisps of that cloud are more personally identifying than others. Yet gather enough of it, and your personal info can create a high-resolution snapshot of you — who you are, what you’re doing, when you’re doing it, and even where you’re doing it, too — particularly if it gets into the wrong hands.

Remember Pig-Pen, the character straight from the old funny pages of Charles Schultz’s Charlie Brown? He’s hard to forget with that ever-present cloud of dust following him around. Charlie Brown once said, “He may be carrying the soil that trod upon by Solomon or Nebuchadnezzar or Genghis Khan!” It’s the same with us and our personal info, except the cloud surrounding us, isn’t the dust of kings and conquerors. They’re motes of info that are of tremendously high value to crooks and bad actors — whether for purposes of identity theft or invasion of privacy.

Protecting your personal info protects your identity and privacy

With all the personal info we create and share on the internet, that calls for protecting it. Otherwise, our personal info could fall into the hands of a hacker or identity thief and end up getting abused, in potentially painful and costly ways.

Here are several things you can do to help ensure that what’s private stays that way:

1) Use a complete security platform that can also protect your privacy.

Square One is to protect your devices with comprehensive online protection software. This defends you against the latest virus, malware, spyware, and ransomware attacks plus further protects your privacy and identity. Also, it can provide strong password protection by generating and automatically storing complex passwords to keep your credentials safer from hackers and crooks who might try to force their way into your accounts.

Further, security software can also include a firewall that blocks unwanted traffic from entering your home network, such as an attacker poking around for network vulnerabilities so that they can “break in” to your computer and steal info.

2) Use a VPN.

Also known as a virtual private network, a VPN helps protect your vital personal info and other data with bank-grade encryption. The VPN encrypts your internet connection to keep your online activity private on any network, even public networks. Using a public network without a VPN can increase your risk because others on the network can potentially spy on your browsing and activity.

If you’re new to the notion of using a VPN, check out this article on VPNs and how to choose one so that you can get the best protection and privacy possible. (Our McAfee+ plans offer a VPN as part of your subscription.)

3) Keep a close grip on your Social Security Number.

In the U.S., the Social Security Number (SSN) is one of the most prized pieces of personal info as it unlocks the door to employment, finances, and much more. First up, keep a close grip on it. Literally. Store your card in a secure location. Not your purse or wallet.

Certain businesses and medical practices might ask you for your SSN for billing purposes and the like. You don’t have to provide it (although some businesses could refuse service if you don’t), and you can always ask if they will accept some alternative form of info. However, there are a handful of instances where an SSN is a requirement. These include:

• Employment or contracting with a business.
• Group health insurance.
• Financial and real estate transactions.
• Applying for credit cards, car loans, and so forth.

Be aware that hackers often get a hold of SSNs because the organization holding that info gets hacked or compromised itself. Minimizing how often you provide your SSN can offer an extra degree of protection.

4) Protect your files.

Protecting your files with encryption is a core concept in data and info security, and thus it’s a powerful way to protect your personal info. It involves transforming data or info into code that requires a digital key to access it in its original, unencrypted format. For example, McAfee+ includes File Lock, which is our file encryption feature that lets you lock important files in secure digital vaults on your device.

Additionally, you can also delete sensitive files with an application such as McAfee Shredder, which securely deletes files so that thieves can’t access them. (Quick fact: deleting files in your trash doesn’t delete them in the truest sense. They’re still there until they’re “shredded” or otherwise overwritten such that they can’t be restored.)

5) Steer clear of those internet “quizzes.”

Which Marvel Universe superhero are you? Does it really matter? After all, such quizzes and social media posts are often grifting pieces of your personal info in a seemingly playful way. While you’re not giving up your SSN, you might be giving up things like your birthday, your pet’s name, your first car…things that people often use to compose their passwords or use as answers to common security questions on banking and financial sites. The one way to pass this kind of quiz is not to take it!

6) Be on the lookout for phishing attacks.

A far more direct form of separating you from your personal info is phishing attacks. Posing as emails from known or trusted brands, financial institutions, or even a friend or family member, a scammer’s attack will try to trick you into sharing important info like your logins, account numbers, credit card numbers, and so on under the guise of providing customer service.

How do you spot such emails? Well, it’s getting a little tougher nowadays because scammers are getting more sophisticated and can make their phishing emails look increasingly legitimate. Even more so with AI tools. However, there are several ways you can spot a phishing email and phony websites. Moreover, our McAfee Scam Protection can do it for you.

7) Keep mum in your social media profile.

You can take two steps to help protect your personal info from being at risk via social media. One, think twice about what you share in that post or photo — like the location of your child’s school or the license plate on your car. Two, set your profile to private so that only friends can see it. Social media platforms like Facebook, Instagram, and others give you the option of making your profile and posts visible to friends only. Choosing this setting keeps the broader internet from seeing what you’re doing, saying, and posting, which can help protect your privacy and gives a scammer less info to exploit. Using our Social Privacy Manager can make that even easier. With only a few clicks, it can adjust more than 100 privacy settings across their social media accounts — making them more private as a result.

8) Look for HTTPS when you browse.

The “S” stands for secure. Any time you’re shopping, banking, or sharing any kind of personal info, look for “https” at the start of the web address. Some browsers also indicate HTTPS by showing a small “lock” icon. Doing otherwise on plain HTTP sites exposes your personal info for anyone who cares to monitor that site for unsecured connections.

9) Lock your devices.

By locking your devices, you protect yourself that much better from personal info and data theft in the event your device is lost, stolen, or even left unattended for a short stretch. Use your password, PIN, facial recognition, thumbprint ID, what have you. Just lock your stuff. In the case of your smartphones, read up on how you can locate your phone or even wipe it remotely if you need to. Apple provides iOS users with a step-by-step guide for remotely wiping devices, and Google offers up a guide for Android users as well.

10) Keep tabs on your credit — and your personal info.

Theft of your personal info can lead to credit cards and other accounts being opened falsely in your name. What’s more, it can take some time before you even become aware of it, such as when your credit score takes a hit or a bill collector comes calling. By checking your credit, you can fix any issues that come up, as companies typically have a clear-cut process for contesting any fraud. You can get a free credit report in the U.S. via the Federal Trade Commission (FTC) and likewise, other nations like the UK have similar free offerings as well.

Consider identity theft protection as well. A strong identity theft protection package pairs well with keeping track of your credit and offers cyber monitoring that scans the dark web to detect for misuse of your personal info. With our identity protection service, we help relieve the burden of identity theft if the unfortunate happens to you with $2M coverage for lawyer fees, travel expenses, lost wages, and more.

NationalPublicData.com Hack Exposes a Nation’s Data

A great many readers this month reported receiving alerts that their Social Security Number, name, address and other personal information were exposed in a breach at a little-known but aptly-named consumer data broker called NationalPublicData.com. This post examines what we know about a breach that has exposed hundreds of millions of consumer records. We’ll also take a closer look at the data broker that got hacked — a background check company founded by an actor and retired sheriff’s deputy from Florida.

On July 21, 2024, denizens of the cybercrime community Breachforums released more than 4 terabytes of data they claimed was stolen from nationalpublicdata.com, a Florida-based company that collects data on consumers and processes background checks.

The breach tracking service HaveIBeenPwned.com and the cybercrime-focused Twitter account vx-underground both concluded the leak is the same information first put up for sale in April 2024 by a prolific cybercriminal who goes by the name “USDoD.”

On April 7, USDoD posted a sales thread on Breachforums for four terabytes of data — 2.9 billion rows of records — they claimed was taken from nationalpublicdata.com. The snippets of stolen data that USDoD offered as teasers showed rows of names, addresses, phone numbers, and Social Security Numbers (SSNs). Their asking price? $3.5 million.

Many media outlets mistakenly reported that the National Public data breach affects 2.9 billion people (that figure actually refers to the number of rows in the leaked data sets). HaveIBeenPwned.com’s Troy Hunt analyzed the leaked data and found it is a somewhat disparate collection of consumer and business records, including the real names, addresses, phone numbers and SSNs of millions of Americans (both living and deceased), and 70 million rows from a database of U.S. criminal records.

Hunt said he found 137 million unique email addresses in the leaked data, but stressed that there were no email addresses in the files containing SSN records.

“If you find yourself in this data breach via HaveIBeenPwned.com, there’s no evidence your SSN was leaked, and if you’re in the same boat as me, the data next to your record may not even be correct.”

Nationalpublicdata.com publicly acknowledged a breach in a statement on Aug. 12, saying “there appears to have been a data security incident that may have involved some of your personal information. The incident appears to have involved a third-party bad actor that was trying to hack into data in late December 2023, with potential leaks of certain data in April 2024 and summer 2024.”

The company said the information “suspected of being breached” contained name, email address, phone number, social security number, and mailing address(es).

“We cooperated with law enforcement and governmental investigators and conducted a review of the potentially affected records and will try to notify you if there are further significant developments applicable to you,” the statement continues. “We have also implemented additional security measures in efforts to prevent the reoccurrence of such a breach and to protect our systems.”

Hunt’s analysis didn’t say how many unique SSNs were included in the leaked data. But according to researchers at Atlas Data Privacy Corp., there are 272 million unique SSNs in the entire records set.

Atlas found most records have a name, SSN, and home address, and that approximately 26 percent of those records included a phone number. Atlas said they verified 5,000 addresses and phone numbers, and found the records pertain to people born before Jan. 1, 2002 (with very few exceptions).

If there is a tiny silver lining to the breach it is this: Atlas discovered that many of the records related to people who are now almost certainly deceased. They found the average age of the consumer in these records is 70, and fully two million records are related to people whose date of birth would make them more than 120 years old today.

TWISTED HISTORY

Where did National Public Data get its consumer data? The company’s website doesn’t say, but it is operated by an entity in Coral Springs, Fla. called Jerico Pictures Inc. The website for Jerico Pictures is not currently responding. However, cached versions of it at archive.org show it is a film studio with offices in Los Angeles and South Florida.

The Florida Secretary of State says Jerico Pictures is owned by Salvatore (Sal) Verini Jr., a retired deputy with the Broward County Sheriff’s office. The Secretary of State also says Mr. Verini is or was a founder of several other Florida companies, including National Criminal Data LLC, Twisted History LLC, Shadowglade LLC and Trinity Entertainment Inc., among others.

Mr. Verini did not respond to multiple requests for comment. Cached copies of Mr. Verini’s vanity domain salvatoreverini.com recount his experience in acting (e.g. a role in a 1980s detective drama with Burt Reynolds) and more recently producing dramas and documentaries for several streaming channels.

Pivoting on the email address used to register that vanity domain, DomainTools.com finds several other domains whose history offers a clearer picture of the types of data sources relied upon by National Public Data.

One of those domains is recordscheck.net (formerly recordscheck.info), which advertises “instant background checks, SSN traces, employees screening and more.” Another now-defunct business tied to Mr. Verini’s email — publicrecordsunlimited.com — said it obtained consumer data from a variety of sources, including: birth, marriage and death records; voting records; professional licenses; state and federal criminal records.

It remains unclear how thieves originally obtained these records from National Public Data. KrebsOnSecurity sought comment from USDoD, who is perhaps best known for hacking into Infragard, an FBI program that facilitates information sharing about cyber and physical threats with vetted people in the private sector.

USDoD said they indeed sold the same data set that was leaked on Breachforums this past month, but that the person who leaked the data did not obtain it from them. USDoD said the data stolen from National Public Data had traded hands several times since it was initially stolen in December 2023.

“The database has been floating around for a while,” USDoD said. “I was not the first one to get it.”

USDoD said the person who originally stole the data from NPD was a hacker who goes by the handle SXUL. That user appears to have deleted their Telegram account several days ago, presumably in response to intense media coverage of the breach.

ANALYSIS

Data brokers like National Public Data typically get their information by scouring federal, state and local government records. Those government files include voting registries, property filings, marriage certificates, motor vehicle records, criminal records, court documents, death records, professional licenses, bankruptcy filings, and more.

Americans may believe they have the right to opt out of having these records collected and sold to anyone. But experts say these underlying sources of information — the above-mentioned “public” records — are carved out from every single state consumer privacy law. This includes California’s privacy regime, which is often held up as the national leader in state privacy regulations.

You see, here in America, virtually anyone can become a consumer data broker. And with few exceptions, there aren’t any special requirements for brokers to show that they actually care about protecting the data they collect, store, repackage and sell so freely.

In February 2023, PeopleConnect, the owners of the background search services TruthFinder and Instant Checkmate, acknowledged a breach affecting 20 million customers who paid the data brokers to run background checks. The data exposed included email addresses, hashed passwords, first and last names, and phone numbers.

In 2019, malicious hackers stole data on more than 1.5 billion people from People Data Labs, a San Francisco data broker whose people-search services linked hundreds of millions of email addresses, LinkedIn and Facebook profiles and more than 200 million valid cell phone numbers.

These data brokers are the digital equivalent of massive oil tankers wandering the coast without GPS or an anchor, because when they get hacked, the effect is very much akin to the ecological and economic fallout from a giant oil spill.

It’s an apt analogy because the dissemination of so much personal data all at once has ripple effects for months and years to come, as this information invariably feeds into a vast underground ocean of scammers who are already equipped and staffed to commit identity theft and account takeovers at scale.

It’s also apt because much like with real-life oil spills, the cleanup costs and effort from data spills — even just vast collections of technically “public” documents like the NPD corpus — can be enormous, and most of the costs associated with that fall to consumers, directly or indirectly.

WHAT SHOULD YOU DO?

Should you worry that your SSN and other personal data might be exposed in this breach? That isn’t necessary for people who’ve been following the advice here for years, which is to freeze one’s credit file at each of the major consumer reporting bureaus. Having a freeze on your files makes it much harder for identity thieves to create new accounts in your name, and it limits who can view your credit information.

The main reason I recommend the freeze is that all of the information ID thieves need to assume your identity is now broadly available from multiple sources, thanks to the multiplicity of data breaches we’ve seen involving SSN data and other key static data points about people.

But beyond that, there are numerous cybercriminal services that offer detailed background checks on consumers, including full SSNs. These services are powered by compromised accounts at data brokers that cater to private investigators and law enforcement officials, and some are now fully automated via Telegram instant message bots. Meaning, if you’re an American who hasn’t frozen their credit files and you haven’t yet experienced some form of new account fraud, the ID thieves probably just haven’t gotten around to you yet.

All Americans are also entitled to obtain a free copy of their credit report weekly from each of the three major credit bureaus. It used to be that consumers were allowed one free report from each of the bureaus annually, but in October 2023 the Federal Trade Commission announced the bureaus had permanently extended a program that lets you check your credit report once a week for free.

If you haven’t done this in a while, now would be an excellent time to order your files. To place a freeze, you need to create an account at each of the three major reporting bureaus, Equifax, Experian and TransUnion. Once you’ve established an account, you should be able to then view and freeze your credit file. Dispute any inaccuracies you may find. If you spot errors, such as random addresses and phone numbers you don’t recognize, do not ignore them: Identity theft and new account fraud are not problems that get easier to solve by letting them fester.

Mr. Verini probably didn’t respond to requests for comment because his company is now the subject of a class-action lawsuit (NB: the lawsuit also erroneously claims 3 billion people were affected). These lawsuits are practically inevitable now after a major breach, but they also have the unfortunate tendency to let regulators and lawmakers off the hook.

Almost every time there’s a major breach of SSN data, Americans are offered credit monitoring services. Most of the time, those services come from one of the three major consumer credit bureaus, the same companies that profit by compiling and selling incredibly detailed dossiers on consumers’ financial lives. The same companies that use dark patterns to trick people into paying for “credit lock” services that achieve a similar result as a freeze but still let the bureaus sell your data to their partners.

But class-actions alone will not drive us toward a national conversation about what needs to change. Americans currently have very few rights to opt out of the personal and financial surveillance, data collection and sale that is pervasive in today’s tech-based economy.

The breach at National Public Data may not be the worst data breach ever. But it does present yet another opportunity for this country’s leaders to acknowledge that the SSN has completely failed as a measure of authentication or authorization. It was never a good idea to use as an authenticator to begin with, and it is certainly no longer suitable for this purpose.

The truth is that these data brokers will continue to proliferate and thrive (and get hacked and relieved of their data) until Congress begins to realize it’s time for some consumer privacy and data protection laws that are relevant to life in the 21st century.

Low-Drama ‘Dark Angels’ Reap Record Ransoms

A ransomware group called Dark Angels made headlines this past week when it was revealed the crime group recently received a record $75 million data ransom payment from a Fortune 50 company. Security experts say the Dark Angels have been around since 2021, but the group doesn’t get much press because they work alone and maintain a low profile, picking one target at a time and favoring mass data theft over disrupting the victim’s operations.

Security firm Zscaler ThreatLabz this month ranked Dark Angels as the top ransomware threat for 2024, noting that in early 2024 a victim paid the ransomware group $75 million — higher than any previously recorded ransom payment. ThreatLabz found Dark Angels has conducted some of the largest ransomware attacks to date, and yet little is known about the group.

Brett Stone-Gross, senior director of threat intelligence at ThreatLabz, said Dark Angels operate using an entirely different playbook than most other ransomware groups. For starters, he said, Dark Angels does not employ the typical ransomware affiliate model, which relies on hackers-for-hire to install malicious software that locks up infected systems.

“They really don’t want to be in the headlines or cause business disruptions,” Stone-Gross said. “They’re about making money and attracting as little attention as possible.”

Most ransomware groups maintain flashy victim leak sites which threaten to publish the target’s stolen data unless a ransom demand is paid. But the Dark Angels didn’t even have a victim shaming site until April 2023. And the leak site isn’t particularly well branded; it’s called Dunghill Leak.

“Nothing about them is flashy,” Stone-Gross said. “For the longest time, they didn’t even want to cause a big headline, but they probably felt compelled to create that leaks site because they wanted to show they were serious and that they were going to post victim data and make it accessible.”

Dark Angels is thought to be a Russia-based cybercrime syndicate whose distinguishing characteristic is stealing truly staggering amounts of data from major companies across multiple sectors, including healthcare, finance, government and education. For large businesses, the group has exfiltrated between 10-100 terabytes of data, which can take days or weeks to transfer, ThreatLabz found.

Like most ransom gangs, Dark Angels will publish data stolen from victims who do not pay. Some of the more notable victims listed on Dunghill Leak include the global food distribution firm Sysco, which disclosed a ransomware attack in May 2023; and the travel booking giant Sabre, which was hit by the Dark Angels in September 2023.

Stone-Gross said Dark Angels is often reluctant to deploy ransomware malware because such attacks work by locking up the target’s IT infrastructure, which typically causes the victim’s business to grind to a halt for days, weeks or even months on end. And those types of breaches tend to make headlines quickly.

“They selectively choose whether they want to deploy ransomware or not,” he said. “If they deem they can encrypt some files that won’t cause major disruptions — but will give them a ton of data — that’s what they’ll do. But really, what separates them from the rest is the volume of data they’re stealing. It’s a whole order of magnitude greater with Dark Angels. Companies losing vast amounts of data will pay these high ransoms.”

So who paid the record $75 million ransom? Bleeping Computer posited on July 30 that the victim was the pharmaceutical giant Cencora (formerly AmeriSourceBergen Corporation), which reported a data security incident to the U.S. Securities and Exchange Commission (SEC) on February 21, 2024.

The SEC requires publicly-traded companies to disclose a potentially material cybersecurity event within four days of the incident. Cencora is currently #10 on the Fortune 500 list, generating more than $262 billion in revenue last year.

Cencora did not respond to questions about whether it had made a ransom payment in connection with the February cybersecurity incident, and referred KrebsOnSecurity to expenses listed under “Other” in the restructuring section of their latest quarterly financial report (PDF). That report states that the majority of the $30 million cost in “Other” was associated with the breach.

Cencora’s quarterly statement said the incident affected a standalone legacy information technology platform in one country and the foreign business unit’s ability to operate in that country for approximately two weeks.

In its most recent State of Ransomware report (PDF), security firm Sophos found the average ransomware payment had increased fivefold in the past year, from $400,000 in 2023 to $2 million. Sophos says that in more than four-fifths (82%) of cases funding for the ransom came from multiple sources. Overall, 40% of total ransom funding came from the organizations themselves and 23% from insurance providers.

Phish-Friendly Domain Registry “.top” Put on Notice

The Chinese company in charge of handing out domain names ending in “.top” has been given until mid-August 2024 to show that it has put in place systems for managing phishing reports and suspending abusive domains, or else forfeit its license to sell domains. The warning comes amid the release of new findings that .top was the most common suffix in phishing websites over the past year, second only to domains ending in “.com.”

On July 16, the Internet Corporation for Assigned Names and Numbers (ICANN) sent a letter to the owners of the .top domain registry. ICANN has filed hundreds of enforcement actions against domain registrars over the years, but in this case ICANN singled out a domain registry responsible for maintaining an entire top-level domain (TLD).

Among other reasons, the missive chided the registry for failing to respond to reports about phishing attacks involving .top domains.

“Based on the information and records gathered through several weeks, it was determined that .TOP Registry does not have a process in place to promptly, comprehensively, and reasonably investigate and act on reports of DNS Abuse,” the ICANN letter reads (PDF).

ICANN’s warning redacted the name of the recipient, but records show the .top registry is operated by a Chinese entity called Jiangsu Bangning Science & Technology Co. Ltd. Representatives for the company have not responded to requests for comment.

Domains ending in .top were represented prominently in a new phishing report released today by the Interisle Consulting Group, which sources phishing data from several places, including the Anti-Phishing Working Group (APWG), OpenPhish, PhishTank, and Spamhaus.

Interisle’s newest study examined nearly two million phishing attacks in the last year, and found that phishing sites accounted for more than four percent of all new .top domains between May 2023 and April 2024. Interisle said .top has roughly 2.76 million domains in its stable, and that more than 117,000 of those were phishing sites in the past year.

ICANN said its review was based on information collected and studied about .top domains over the past few weeks. But the fact that high volumes of phishing sites are being registered through Jiangsu Bangning Science & Technology Co Ltd. is hardly a new trend.

For example, more than 10 years ago the same Chinese registrar was the fourth most common source of phishing websites, as tracked by the APWG. Bear in mind that the APWG report excerpted below was published more than a year before Jiangsu Bangning received ICANN approval to introduce and administer the new .top registry.

A fascinating new wrinkle in the phishing landscape is the growth in scam pages hosted via the InterPlanetary File System (IPFS), a decentralized data storage and delivery network that is based on peer-to-peer networking. According to Interisle, the use of IPFS to host and launch phishing attacks — which can make phishing sites more difficult to take down — increased a staggering 1,300 percent, to roughly 19,000 phishing sites reported in the last year.

Last year’s report from Interisle found that domain names ending in “.us” — the top-level domain for the United States — were among the most prevalent in phishing scams. While .us domains are not even on the Top 20 list of this year’s study, “.com” maintained its perennial #1 spot as the largest source of phishing domains overall.

A year ago, the phishiest domain registrar by far was Freenom, a now-defunct registrar that handed out free domains in several country-code TLDs, including .tk, .ml, .ga and .cf. Freenom went out of business after being sued by Meta, which alleged Freenom ignored abuse complaints while monetizing traffic to abusive domains.

Following Freenom’s demise, phishers quickly migrated to other new low-cost TLDs and to services that allow anonymous, free domain registrations — particularly subdomain services. For example, Interisle found phishing attacks involving websites created on Google’s blogspot.com skyrocketed last year more than 230 percent. Other subdomain services that saw a substantial growth in domains registered by phishers include weebly.com, github.io, wix.com, and ChangeIP, the report notes.

Interisle Consulting partner Dave Piscitello said ICANN could easily send similar warning letters to at least a half-dozen other top-level domain registries, noting that spammers and phishers tend to cycle through the same TLDs periodically — including .xyz, .info, .support and .lol, all of which saw considerably more business from phishers after Freenom’s implosion.

Piscitello said domain registrars and registries could significantly reduce the number of phishing sites registered through their services just by flagging customers who try to register huge volumes of domains at once. Their study found that at least 27% of the domains used for phishing were registered in bulk — i.e. the same registrant paid for hundreds or thousands of domains in quick succession.

The report includes a case study in which a phisher this year registered 17,562 domains over the course of an eight-hour period — roughly 38 domains per minute — using .lol domains that were all composed of random letters.

ICANN tries to resolve contract disputes privately with the registry and registrar community, and experts say the nonprofit organization usually only publishes enforcement letters when the recipient is ignoring its private notices. Indeed, ICANN’s letter notes Jiangsu Bangning didn’t even open its emailed notifications. It also cited the registry for falling behind in its ICANN membership fees.

With that in mind, a review of ICANN’s public enforcement activity suggests two trends: One is that there have been far fewer public compliance and enforcement actions in recent years — even as the number of new TLDs has expanded dramatically.

The second is that in a majority of cases, the failure of a registry or registrar to pay its annual ICANN membership fees was cited as a reason for a warning letter. A review of nearly two dozen enforcement letters ICANN has sent to domain registrars since 2022 shows that failure to pay dues was cited as a reason (or the reason) for the violation at least 75 percent of the time.

Piscitello, a former vice president of security at ICANN, said nearly all breach notices sent out while he was at ICANN were because the registrar owed money.

“I think the rest is just lipstick to suggest that ICANN’s on top of DNS Abuse,” Piscitello said.

KrebsOnSecurity has sought comment from ICANN and will update this story if they respond.

ICANN said most of its investigations are resolved and closed through the initial informal resolution stage, and that hundreds of enforcement cases are initiated during this stage with the contracted parties who are required to demonstrate compliance, become compliant, and/or present and implement remediation plans to prevent the recurrence of those enforcement issues.

“It is important to take into account that, prior to issuing any notice of breach to a registrar or registry operator, ICANN Compliance conducts an overall contractual compliance ‘health check’ of the relevant contracted party,” ICANN said in a written response to questions. “During this check, ICANN Compliance proactively reviews the contracted party’s compliance with obligations across the agreements and policies. Any additional contractual violation found during these checks is added to the Notice of Breach. It is not uncommon for parties who failed to comply with contractual obligations (whether they are related to DNS Abuse, RDDS, or others) to also be in arrears with ICANN fees.”

Update, 11:49 p.m. ET: Added statement from ICANN. Clarified Piscitello’s former role at ICANN.

Alleged Boss of ‘Scattered Spider’ Hacking Group Arrested

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.

“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 called 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.

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.

Patch Tuesday, June 2024 “Recall” Edition

Microsoft today released updates to fix more than 50 security vulnerabilities in Windows and related software, a relatively light Patch Tuesday this month for Windows users. The software giant also responded to a torrent of negative feedback on a new feature of Redmond’s flagship operating system that constantly takes screenshots of whatever users are doing on their computers, saying the feature would no longer be enabled by default.

Last month, Microsoft debuted Copilot+ PCs, an AI-enabled version of Windows. Copilot+ ships with a feature nobody asked for that Redmond has aptly dubbed Recall, which constantly takes screenshots of what the user is doing on their PC. Security experts roundly trashed Recall as a fancy keylogger, noting that it would be a gold mine of information for attackers if the user’s PC was compromised with malware.

Microsoft countered that Recall snapshots never leave the user’s system, and that even if attackers managed to hack a Copilot+ PC they would not be able to exfiltrate on-device Recall data. But that claim rang hollow after former Microsoft threat analyst Kevin Beaumont detailed on his blog how any user on the system (even a non-administrator) can export Recall data, which is just stored in an SQLite database locally.

“I’m not being hyperbolic when I say this is the dumbest cybersecurity move in a decade,” Beaumont said on Mastodon.

In a recent Risky Business podcast, host Patrick Gray noted that the screenshots created and indexed by Recall would be a boon to any attacker who suddenly finds himself in an unfamiliar environment.

“The first thing you want to do when you get on a machine if you’re up to no good is to figure out how someone did their job,” Gray said. “We saw that in the case of the SWIFT attacks against central banks years ago. Attackers had to do screen recordings to figure out how transfers work. And this could speed up that sort of discovery process.”

Responding to the withering criticism of Recall, Microsoft said last week that it will no longer be enabled by default on Copilot+ PCs.

Only one of the patches released today — CVE-2024-30080 — earned Microsoft’s most urgent “critical” rating, meaning malware or malcontents could exploit the vulnerability to remotely seize control over a user’s system, without any user interaction.

CVE-2024-30080 is a flaw in the Microsoft Message Queuing (MSMQ) service that can allow attackers to execute code of their choosing. Microsoft says exploitation of this weakness is likely, enough to encourage users to disable the vulnerable component if updating isn’t possible in the short run. CVE-2024-30080 has been assigned a CVSS vulnerability score of 9.8 (10 is the worst).

Kevin Breen, senior director of threat research at Immersive Labs, said a saving grace is that MSMQ is not a default service on Windows.

“A Shodan search for MSMQ reveals there are a few thousand potentially internet-facing MSSQ servers that could be vulnerable to zero-day attacks if not patched quickly,” Breen said.

CVE-2024-30078 is a remote code execution weakness in the Windows WiFi Driver, which also has a CVSS score of 9.8. According to Microsoft, an unauthenticated attacker could exploit this bug by sending a malicious data packet to anyone else on the same network — meaning this flaw assumes the attacker has access to the local network.

Microsoft also fixed a number of serious security issues with its Office applications, including at least two remote-code execution flaws, said Adam Barnett, lead software engineer at Rapid7.

“CVE-2024-30101 is a vulnerability in Outlook; although the Preview Pane is a vector, the user must subsequently perform unspecified specific actions to trigger the vulnerability and the attacker must win a race condition,” Barnett said. “CVE-2024-30104 does not have the Preview Pane as a vector, but nevertheless ends up with a slightly higher CVSS base score of 7.8, since exploitation relies solely on the user opening a malicious file.”

Separately, Adobe released security updates for Acrobat, ColdFusion, and Photoshop, among others.

As usual, the SANS Internet Storm Center has the skinny on the individual patches released today, indexed by severity, exploitability and urgency. Windows admins should also keep an eye on AskWoody.com, which often publishes early reports of any Windows patches gone awry.

Treasury Sanctions Creators of 911 S5 Proxy Botnet

The U.S. Department of the Treasury today unveiled sanctions against three Chinese nationals for allegedly operating 911 S5, an online anonymity service that for many years was the easiest and cheapest way to route one’s Web traffic through malware-infected computers around the globe. KrebsOnSecurity identified one of the three men in a July 2022 investigation into 911 S5, which was massively hacked and then closed ten days later.

From 2015 to July 2022, 911 S5 sold access to hundreds of thousands of Microsoft Windows computers daily, as “proxies” that allowed customers to route their Internet traffic through PCs in virtually any country or city around the globe — but predominantly in the United States.

911 built its proxy network mainly by offering “free” virtual private networking (VPN) services. 911’s VPN performed largely as advertised for the user — allowing them to surf the web anonymously — but it also quietly turned the user’s computer into a traffic relay for paying 911 S5 customers.

911 S5’s reliability and extremely low prices quickly made it one of the most popular services among denizens of the cybercrime underground, and the service became almost shorthand for connecting to that “last mile” of cybercrime. Namely, the ability to route one’s malicious traffic through a computer that is geographically close to the consumer whose stolen credit card is about to be used, or whose bank account is about to be emptied.

In July 2022, KrebsOnSecurity published a deep dive into 911 S5, which found the people operating this business had a history of encouraging the installation of their proxy malware by any means available. That included paying affiliates to distribute their proxy software by secretly bundling it with other software.

That story named Yunhe Wang from Beijing as the apparent owner or manager of the 911 S5 proxy service. In today’s Treasury action, Mr. Wang was named as the primary administrator of the botnet that powered 911 S5.

“A review of records from network infrastructure service providers known to be utilized by 911 S5 and two Virtual Private Networks (VPNs) specific to the botnet operation (MaskVPN and DewVPN) showed Yunhe Wang as the registered subscriber to those providers’ services,” reads the Treasury announcement.

Update, May 29, 12:26 p.m. ET: The U.S. Department of Justice (DOJ) just announced they have arrested Wang in connection with the 911 S5 botnet. The DOJ says 911 S5 customers have stolen billions of dollars from financial institutions, credit card issuers, and federal lending programs.

“911 S5 customers allegedly targeted certain pandemic relief programs,” a DOJ statement on the arrest reads. “For example, the United States estimates that 560,000 fraudulent unemployment insurance claims originated from compromised IP addresses, resulting in a confirmed fraudulent loss exceeding $5.9 billion. Additionally, in evaluating suspected fraud loss to the Economic Injury Disaster Loan (EIDL) program, the United States estimates that more than 47,000 EIDL applications originated from IP addresses compromised by 911 S5. Millions of dollars more were similarly identified by financial institutions in the United States as loss originating from IP addresses compromised by 911 S5.”

The sanctions say Jingping Liu was Yunhe Wang’s co-conspirator in the laundering of criminally derived proceeds generated from 911 S5, mainly virtual currency. The government alleges the virtual currencies paid by 911 S5 users were converted into U.S. dollars using over-the-counter vendors who wired and deposited funds into bank accounts held by Liu.

“Jingping Liu assisted Yunhe Wang by laundering criminally derived proceeds through bank accounts held in her name that were then utilized to purchase luxury real estate properties for Yunhe Wang,” the document continues. “These individuals leveraged their malicious botnet technology to compromise personal devices, enabling cybercriminals to fraudulently secure economic assistance intended for those in need and to terrorize our citizens with bomb threats.”

The third man sanctioned is Yanni Zheng, a Chinese national the U.S. Treasury says acted as an attorney for Wang and his firm — Spicy Code Company Limited — and helped to launder proceeds from the business into real estate holdings. Spicy Code Company was also sanctioned, as well as Wang-controlled properties Tulip Biz Pattaya Group Company Limited, and Lily Suites Company Limited.

Ten days after the July 2022 story here on 911 S5, the proxy network abruptly closed up shop, citing a data breach that destroyed key components of its business operations.

In the months that followed, however, 911 S5 would resurrect itself under a different name: Cloud Router. That’s according to spur.us, a U.S.-based startup that tracks proxy and VPN services. In February 2024, Spur published research showing the Cloud Router operators reused many of the same components from 911 S5, making it relatively simple to draw a connection between the two.

Spur found that Cloud Router was being powered by a new VPN service called PaladinVPN, which made it much more explicit to users that their Internet connections were going to be used to relay traffic for others. At the time, Spur found Cloud Router had more than 140,000 Internet addresses for rent.

Spur co-founder Riley Kilmer said Cloud Router appears to have suspended or ceased operations sometime this past weekend. Kilmer said the number of proxies advertised by the service had been trending downwards quite recently before the website suddenly went offline.

Cloud Router’s homepage is currently populated by a message from Cloudflare saying the site’s domain name servers are pointing to a “prohibited IP.”

JA4+ Details

JA4+ is a set of simple yet powerful network fingerprints for multiple protocols that are both human and machine readable, facilitating improved threat-hunting and security analysis. If you are unfamiliar with network fingerprinting, I encourage you to read my blogs releasing JA3 here, JARM here, and this excellent blog by Fastly on the State of TLS Fingerprinting which outlines the history of the aforementioned along with their problems. JA4+ brings dedicated support, keeping the methods up-to-date as the industry changes.

All JA4+ fingerprints have an a_b_c format, delimiting the different sections that make up the fingerprint. This allows for hunting and detection utilizing just ab or ac or c only. If one wanted to just do analysis on incoming cookies into their app, they would look at JA4H_c only. This new locality-preserving format facilitates deeper and richer analysis while remaining simple, easy to use, and allowing for extensibility.

For example; GreyNoise is an internet listener that identifies internet scanners and is implementing JA4+ into their product. They have an actor who scans the internet with a constantly changing single TLS cipher. This generates a massive amount of completely different JA3 fingerprints but with JA4, only the b part of the JA4 fingerprint changes, parts a and c remain the same. As such, GreyNoise can track the actor by looking at the JA4_ac fingerprint (joining a+c, dropping b).

Current methods and implementation details:
| Full Name | Short Name | Description | |---|---|---| | JA4 | JA4 | TLS Client Fingerprinting
| JA4Server | JA4S | TLS Server Response / Session Fingerprinting | JA4HTTP | JA4H | HTTP Client Fingerprinting | JA4Latency | JA4L | Latency Measurment / Light Distance | JA4X509 | JA4X | X509 TLS Certificate Fingerprinting | JA4SSH | JA4SSH | SSH Traffic Fingerprinting | JA4TCP | JA4T | TCP Client Fingerprinting | JA4TCPServer | JA4TS | TCP Server Response Fingerprinting | JA4TCPScan | JA4TScan | Active TCP Fingerprint Scanner

Q&A

Q: Why are you sorting the ciphers? Doesn't the ordering matter?
A: It does but in our research we've found that applications and libraries choose a unique cipher list more than unique ordering. This also reduces the effectiveness of "cipher stunting," a tactic of randomizing cipher ordering to prevent JA3 detection.

Q: Why are you sorting the extensions?
A: Earlier in 2023, Google updated Chromium browsers to randomize their extension ordering. Much like cipher stunting, this was a tactic to prevent JA3 detection and "make the TLS ecosystem more robust to changes." Google was worried server implementers would assume the Chrome fingerprint would never change and end up building logic around it, which would cause issues whenever Google went to update Chrome.

So I want to make this clear: JA4 fingerprints will change as application TLS libraries are updated, about once a year. Do not assume fingerprints will remain constant in an environment where applications are updated. In any case, sorting the extensions gets around this and adding in Signature Algorithms preserves uniqueness.

Q: Doesn't TLS 1.3 make fingerprinting TLS clients harder?
A: No, it makes it easier! Since TLS 1.3, clients have had a much larger set of extensions and even though TLS1.3 only supports a few ciphers, browsers and applications still support many more.

How Did Authorities Identify the Alleged Lockbit Boss?

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.

Ex-NSA Employee Sentenced to 22 Years for Trying to Sell U.S. Secrets to Russia

A former employee of the U.S. National Security Agency (NSA) has been sentenced to nearly 22 years (262 months) in prison for attempting to transfer classified documents to Russia. "This sentence should serve as a stark warning to all those entrusted with protecting national defense information that there are consequences to betraying that trust," said FBI Director Christopher Wray.

Man Who Mass-Extorted Psychotherapy Patients Gets Six Years

A 26-year-old Finnish man was sentenced to more than six years in prison today after being convicted of hacking into an online psychotherapy clinic, leaking tens of thousands of patient therapy records, and attempting to extort the clinic and patients.

On October 21, 2020, the Vastaamo Psychotherapy Center in Finland became the target of blackmail when a tormentor identified as “ransom_man” demanded payment of 40 bitcoins (~450,000 euros at the time) in return for a promise not to publish highly sensitive therapy session notes Vastaamo had exposed online.

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

Finnish prosecutors quickly zeroed in on a suspect: Julius “Zeekill” Kivimäki, a notorious criminal hacker convicted of committing tens of thousands of cybercrimes before he became an adult. After being charged with the attack in October 2022, Kivimäki fled the country. He was arrested four months later in France, hiding out under an assumed name and passport.

Antti Kurittu is a former criminal investigator who worked on an investigation involving Kivimäki’s use of the Zbot botnet, among other activities Kivimäki engaged in as a member of the hacker group Hack the Planet (HTP).

Kurittu said the prosecution had demanded at least seven years in jail, and that the sentence handed down was six years and three months. Kurittu said prosecutors knocked a few months off of Kivimäki’s sentence because he agreed to pay compensation to his victims, and that Kivimäki will remain in prison during any appeal process.

“I think the sentencing was as expected, knowing the Finnish judicial system,” Kurittu told KrebsOnSecurity. “As Kivimäki has not been sentenced to a non-suspended prison sentence during the last five years, he will be treated as a first-timer, his previous convictions notwithstanding.”

But because juvenile convictions in Finland don’t count towards determining whether somebody is a first-time offender, Kivimäki will end up serving approximately half of his sentence.

“This seems like a short sentence when taking into account the gravity of his actions and the life-altering consequences to thousands of people, but it’s almost the maximum the law allows for,” Kurittu said.

Kivimäki initially gained notoriety as a self-professed member of the Lizard Squad, a mainly low-skilled hacker group that specialized in DDoS attacks. But American and Finnish investigators say Kivimäki’s involvement in cybercrime dates back to at least 2008, when he was introduced to a founding member of what would soon become HTP.

Finnish police said Kivimäki also used the nicknames “Ryan”, “RyanC” and “Ryan Cleary” (Ryan Cleary was actually a member of a rival hacker group — LulzSec — who was sentenced to prison for hacking).

Kivimäki and other HTP members were involved in mass-compromising web servers using known vulnerabilities, and by 2012 Kivimäki’s alias Ryan Cleary was selling access to those servers in the form of a DDoS-for-hire service. Kivimäki was 15 years old at the time.

In 2013, investigators going through devices seized from Kivimäki found computer code that had been used to crack more than 60,000 web servers using a previously unknown vulnerability in Adobe’s ColdFusion software. KrebsOnSecurity detailed the work of HTP in September 2013, after the group compromised servers inside data brokers LexisNexis, Kroll, and Dun & Bradstreet.

The group used the same ColdFusion flaws to break into the National White Collar Crime Center (NWC3), a non-profit that provides research and investigative support to the U.S. Federal Bureau of Investigation (FBI).

As KrebsOnSecurity reported at the time, this small ColdFusion botnet of data broker servers was being controlled by the same cybercriminals who’d assumed control over SSNDOB, which operated one of the underground’s most reliable services for obtaining Social Security Number, dates of birth and credit file information on U.S. residents.

Kivimäki was responsible for making an August 2014 bomb threat against former Sony Online Entertainment President John Smedley that grounded an American Airlines plane. Kivimäki also was involved in calling in multiple fake bomb threats and “swatting” incidents — reporting fake hostage situations at an address to prompt a heavily armed police response to that location.

Ville Tapio, the former CEO of Vastaamo, was fired and also prosecuted following the breach. Ransom_man bragged about Vastaamo’s sloppy security, noting the company had used the laughably weak username and password “root/root” to protect sensitive patient records.

Investigators later found Vastaamo had originally been hacked in 2018 and again in 2019. In April 2023, a Finnish court handed down a three-month sentence for Tapio, but that sentence was suspended because he had no previous criminal record.
