The Australian city of Perth is by some measures the world’s most isolated major metropolis, but is still sufficiently connected to US law enforcement authorities that the FBI was able to help Australia’s Federal Police (AFP) to find two men they believe were the masterminds of TeamPCP, a cybercrime crew that conducted prominent supply chain attacks. According to the AFP, two men aged 21 and 23 arrested on Wednesday “were principal participants in the activities of the cybercrime syndicate and received payments in cryptocurrency for their roles in the illegal activity.” An FBI Facebook post names one of the arrested men as Ruben Thomson and describes him as “the alleged leader of the cybercriminal group TeamPCP.” Australian media named the second man as 23-year-old Louis Michael Gaebler. Investigations into the pair started in April 2026, after Australian authorities and the FBI “received information from multiple cyber threat assessment companies regarding a syndicate that allegedly inserted malicious code into software available on an open-source repository, which was then unwittingly used by other developers.” Researchers detected some of those activities before April: In March, we reported that researchers spotted a supply chain attack on the open source scanner Trivy. Another of TeamPCP’s attacks was the Shai-Hulud worm, which attacks npm packages, tries to infect them and goes looking for credentials to major public clouds or services like GitHub. If the worm burrowed into its targets, it would either try to replicate to continue its attacks, or wipe the environment out of spite. The AFP’s “We cuffed ‘em!” announcement estimates that TeamPCP’s supply chain attacks “potentially compromised more than 1000 organisations globally, enabling the theft of more than 500,000 credentials, and the exfiltration of at least 300 gigabytes of data.” Australia’s Feds estimate “the financial impact includes global remediation costs estimated to be hundreds of millions of dollars.” As is often the case in such matters, the arrested men were found with electronic devices and other items which authorities seized. “A large volume of data seized is being forensically examined and the investigation remains ongoing,” the AFP wrote, adding “Further arrests and charges have not been ruled out.” Indeed, the Feds note that they arrested the two at different locations in the suburbs of Perth and searched a third property nearby. ® Bootnote: Perth is considered the site of the original “Black Swan” event, as swans there – and across much of Australia – are black. Early European explorers who explored Australia's west coast were astounded when they saw the black birds, as the “fact” that all swans are white was at the time a metaphor for the existence of absolute truths.

PWNED Welcome back to PWNED, the weekly column where we explore the frightening and amusing world of foolish infosec errors. This week, it's all about a test site that exposed real information. Have a story about someone leaving a gaping hole in their network? Share it with us at pwned@sitpub.com. Anonymity is available upon request. Our story comes courtesy of Mia Morin, Editor & AI Quality Analyst at Intimeros, a site that rates, reviews, and evaluates AI companions – yes, that means boyfriends and girlfriends, as well as other kinds of pals. The trouble started during a redesign when one of Morin’s colleagues was working on a test version of the site. The test site was supposed to be password-protected, but the colleague turned off the protection so they could show a client what they were working on. Password protection remained disabled for three weeks without anyone noticing. Then, one day, Morin noticed that the test site had been indexed by Google. Apparently, nobody thought to use a robots.txt file to exclude this beta-level domain from search. While the site was publicly accessible without password protection, anyone could see unpublished reviews, prices, and private product notes about the different AI companion services. That’s because the test site was connected to a real live version of the production database. This was all editorial content, so no user data was exposed. However, it could have allowed competitors to see everything that Intimeros was working on and to deduce their entire editorial strategy. After she noticed what was wrong, Morin took swift action to protect the test site from prying eyes. “We restored password protection, blocked search engines from indexing the draft pages and changed all the system access keys,” Morin said. “Now, we secure every test site just like our official website and run weekly automated scans to catch exposed pages.” What we can learn from this is kind of obvious. Never forget to lock down the test or staging versions of your websites. Make sure that they not only require logins, but also have tools in place to block search and AI crawling. Better still, place your staging site on a private server and require someone to use a VPN to get to it in the first place. ®

After an affair with a fellow police officer ended, a Georgia cop used Flock to track her movements—and those of a man whose vehicle often showed up near hers, internal investigation records show.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) said it’s responding to a “major” cybersecurity incident shortly after the Qilin ransomware gang posted the US federal law enforcement agency on its leak site. An ATF spokesperson told The Register the intruders accessed a “standalone computer system containing information about targets of ATF investigations” that wasn’t connected to any other ATF systems. “There is no indication that the incident has affected the ATF enterprise network, the ATF eForms system, or any other ATF system,” according to a statement posted on the firearms agency’s website. The spokesperson declined to answer any additional questions about the breach, including Qilin’s claims, the ransom demand, and what data was stolen or how much. “ATF is unable to comment due to an ongoing investigation,” the spokesperson said. ATF, which is housed under the US Department of Justice, said it’s “coordinating closely” with the DOJ to investigate the breach, and “immediately” blocked connections to the affected IT environment upon discovering the incident. The statement said the security breach had not affected ATF’s operations and noted that senior Justice Department officials designated the compromise as a “major incident” under federal guidelines. Shortly before ATF posted its security-incident notice on its website, Russia-linked Qilin ransomware criminals listed the firearms agency on its leak site. The post, seen by The Register and shared on social media, did not say what data Qilin claimed to have stolen, how much, or provide samples to substantiate the claim. Qilin, the notorious crew behind the 2024 attack on pathology provider Synnovis that disrupted NHS services in the UK, was one of the most prolific ransomware gangs in July, according to Comparitech. The firm, which reviews cybersecurity products and provides data analysis, counted 799 ransomware incidents last month, up from 668 in June. Qilin claimed 125 of those.® Editor's note: This story was amended post-publication with comment from ATF.

Schrödinger's Cat, the famous 1935 thought experiment, imagines a cat that, for reasons rooted in quantum physics we need not dwell on here, is simultaneously alive and dead. In a landscape of relentless cyberattacks and mounting infrastructural complexity, a routine backup task can appear finished, with every box ticked and every check made. The job is not actually done, however, until it has been verified as fully ready for recovery in the event of cyber disaster. A task that looks sorted can turn out, under scrutiny, to be anything but. A backup can be logged as 'complete' once data has been copied to storage, but a recoverable workload is another matter entirely. It means that when a business goes down, its workloads can be restored to their state at the point of attack with nothing lost. By the time you realize you are on the wrong side of that ambiguity, it may be too late: your data is in the hands of the bad guys, or destroyed, and this time the cat really is dead. This is not a problem to which IT bosses and managed service provider (MSP) management are entirely oblivious. Most organizations recognize to some degree that their backup may not be 100 percent watertight. Cybersecurity management specialist Kaseya recently partnered with 1105 Media to survey 200 IT professionals about the realities shaping cyber resilience planning. Some 53 percent were no more than 'somewhat confident' in their organization's ability to fully recover from a ransomware attack, and admitted their backups were supported by no better than 'limited testing'. A significant proportion had even less faith in their recovery capabilities, while only 15 percent were 'very confident' they could get back on track with no loss. Verify and survive Understanding what a verified backup means, and what role verification plays in the recovery challenge weighing on so many IT leaders, is where any sensible resilience plan begins. Backups are vital but they do not guarantee recovery on their own. What matters is confirming that a backup job will hold up in a disaster. Verification is the process of proving that backed-up data is complete, uncorrupted, and fully restorable in an emergency, offering evidence that recovery is possible during a critical outage, hardware failure or ransomware attack. It is essential whether you run an IT department or an MSP responsible for client protection: unless you can prove clients are protected, there is every chance they are not. "Backup isn't done and entrustable until you've gone in and made sure that the application actually works and can be brought back to the recovery environment," explains Brent Torre, GM of cyber resilience at Kaseya. "Historically, it's just taken too much time and resource for a lot of people to even attempt that. And where they have been verifying, they haven't been doing it regularly enough to ensure real protection." Not all approaches to verification are of equal value. IT departments still relying on intermittent manual verification are operating on blind trust: warnings thrown up by the process can be misread, failures overlooked, and the result is a dangerous mix of false negatives that waste time and false positives that expose the organization to real risk. Manual screenshot verification is a proven way to squander a security budget , tying up highly qualified staff on needless work and pulling their expertise away from where it is genuinely needed. Nobody wants seasoned engineers spending hours reviewing screenshots, second-guessing outputs and trying to determine whether a backup worked. Where static verification methods once had a place, today's complex IT ecosystems have made them redundant. Across an estate spanning in-house systems, SaaS and cloud endpoints, basic verification cannot cope, picking up only surface-level signals and lacking the design to operate at scale. At scale, the inefficiencies of manual verification multiply and response times slow to a crawl. A minor inefficiency can quietly become a serious bottleneck without anyone noticing, and legacy methods can create the illusion that everything is working perfectly while catastrophe waits around the corner. As Torre points out, light-touch checking is unlikely to satisfy the ever-increasing regulatory burden around recovery and resilience. "Some compliance frameworks explicitly state that you must test recovery on a frequent basis," he says. "It's becoming more important than ever that organisations are able to do that." Let AI handle the heat The emerging gold standard is AI-powered screenshot verification, which replaces the best-efforts manual checking of overstretched human teams. It works by automatically booting up virtualized backups, capturing a screenshot and analyzing the image to confirm the backup ran correctly. Where rigid, rule-based checks fall short, context-aware visual AI combined with OCR accurately identifies login screens, dashboards and maintenance states, and evaluates every element with precision. The result is 99.9 percent verification accuracy and sharply reduced false positives, alongside far greater confidence in every backup. This is welcome news for IT managers facing budget shortfalls and a drought of experienced talent, and it is what MSPs need as they try to make the economics of recovery stack up. Remove the manual effort and the constant checking of false alarms, and the gains mount quickly. Human teams are free for higher-value work, SLA confidence rises, customer trust improves, and environments can scale without ballooning overheads. AI-powered verification is no longer a maybe for today's MSPs; it is the only route forward that makes sense on the P&L. The good news is that AI-powered screenshot verification does not require major up-front investment or deep internal expertise. Datto, the cybersecurity and data protection outfit owned by Kaseya, has built the latest verification technology directly into its business continuity and disaster recovery (BCDR) platform, so that deployment stays simple and disruption to existing workflows is minimal. This kind of AI-powered screenshot verification is designed to strip uncertainty out of the process and give IT teams confidence that backed-up data is complete and recoverable. The ideal solution does so at scale, and without adding complexity, by working within the workflows already in place. With Datto there is the further option of integrating remote monitoring and management (RMM) with the BCDR product, which enables proactive remediation through automated deployments, the merging of backup health with endpoint alerts, and virtual restores launched directly from a single management console. "It's key to have context and visibility into the backup estate through your RMM so you know that you are up to date on patching, on antivirus definitions and backups," says Torre. "With all of that integrated within the RMM solution, you have the ability to understand your risk profile across the fleet in terms of protection. You know in the event that something needs to be recovered. And you can start a backup-initiated recovery directly from the RMM platform." The gold standard to aim for, he concludes, is continuous validation and automated remediation, not the ability to look in now and again to see what is going on. The perfect verification solution , he adds, should be 'impossibly easy to use', requiring humans to exert zero cognitive effort on backup beyond deploying a new client and initiating a recovery. By giving yourself the means to distinguish between a completed backup job and a recoverable workload, you have set yourself apart from the kind of IT manager or MSP who only spots a problem after something has gone wrong. By deploying AI-powered verification, you stop treating backup as a probability and start treating it as a proof. You know what you have. Then when something goes wrong, and it will, that certainty is the only thing standing between a fast recovery and a very long night. MSPs looking to unify backup and security into a single resilience practice can start with the When Backup Meets Security in the MSP Stack whitepaper. Sponsored by Datto.

The company behind three of the UK’s busiest airports says “a quantity” of data was stolen by an extortion group during a recent “cybersecurity incident." Manchester Airports Group (MAG), which operates Manchester Airport in the North West of England, Essex’s Stansted Airport, and East Midlands Airport in Derbyshire, confirmed the attack did not involve ransomware. A MAG spokesperson confirmed the details to The Register, as well as the scale of the breach, which is currently thought to have affected 8.7 million customers. The company, whose airports served a record 66 million customers in the past financial year, said that the overwhelming majority of those affected have only had their email addresses compromised. In most cases, these email addresses were collected during the sign-up phase for the airports’ public Wi-Fi services, MAG said. It told The Register that this scenario dwarfed every other. The next most common involved data taken from customers who had made "speculative enquiries" - i.e. they entered their details in the process of booking car parking or Fast Track, but did not complete it. An even greater minority of the data came from bookings that were actually completed. The Information Commissioner’s Office (ICO) asked MAG not to share details of the ransom note, the extortion demands, or the group name, mainly to avoid helping those responsible gain notoriety. MAG did, however, tell us that the group's extortion demands, in this case, were considerably lower than what the group is known to ask for, per the ICO's understanding. It has not paid the extortionists. “We have informed and are working with the relevant authorities,” said MAG in a statement. “At no point has passenger safety or aviation security been compromised.” MAG said the attackers compromised one of its systems, which it did not specifically identify, and then went on to steal the files from a database hosted by a third party. Company chiefs see this attack as "a hack, not a lapse." The spokesperson said it was a sophisticated attack and not the result of a human mistake, such as staff giving away credentials. It confirmed that none of its airports experienced operational disruption as part of the attack, and that the affected system does not store bank or payment details. However, “as a precautionary measure,” it temporarily revoked access to its Manage My Booking service. Customers who want to amend or cancel a booking due within 72 hours of the statement going live are being advised to contact customer services. “We would like to reassure customers that Manchester Airport Group takes the security of customer information extremely seriously and we apologise for any inconvenience or concern caused.” Affected customers have already been contacted, including a few Reg readers who kindly alerted us to the news. While MAG continues to investigate the incident, customers are advised to be extra vigilant to potential phishing attempts, and remain assured that there is no danger of visiting MAG’s airports as a result of the cyberattack. One Reg reader griped that in addition to being charged £80 for five days of parking at Stansted, receiving the email informing him that it had also allowed his personal data to be stolen via a cybersecurity breach added insult to injury. ®

Authorities in Australia have arrested two men believed to be members of TeamPCP, a prolific cybercrime and data extortion group blamed for perpetrating the longest running spree of software supply chain attacks ever.

In a statement released today, the Australian Federal Police (AFP) said two men from Western Australia, aged 21 and 23, were arrested in connection with a “sophisticated cybercrime syndicate that allegedly created malicious open-source software to rob thousands of global businesses.”

The AFP did not name the defendants, but KrebsOnSecurity learned the 21-year-old suspect’s real identity in June, and has been communicating with him ever since. This story includes interviews with TeamPCP’s self-described spokesperson, and examines clues left behind by the TeamPCP leader that likely led to his undoing.

TeamPCP vaulted onto the cybercrime scene in late 2025, embedding malicious code in hundreds of open source software tools and extorting victims for profit. Members of the group made headlines by compromising corporate cloud environments using a self-propagating worm dubbed Shai-Hulud, which added malicious code to open source programs maintained by developers whose credentials at public code repositories like GitHub or NPM were phished or stolen.

Writing for Wired, journalist Andy Greenberg described TeamPCP’s core tactic as a kind of cyclical exploitation of software developers.

“The hackers gain access to a network where an open source tool commonly used by coders is being developed,” Greenberg wrote in May. “The hackers plant malware in the tool that ends up on other software developers’ machines, including some who are writing other tools intended to be used by coders. The malware allows TeamPCP’s hackers to steal credentials that let them publish malicious versions of those software development tools, too. The cycle repeats, and TeamPCP’s collection of breached networks grows.”

TeamPCP also has practiced something akin to cyclical recruitment. In May, the source code for the third iteration of Shai-Hulud was published online, and TeamPCP soon after launched a contest offering $1,000 in virtual currency to whichever participant could conduct the largest supply chain operation using the worm’s code. According to the contest rules, participants were scored based on the number of weekly and monthly downloads of packages they compromised — directly incentivizing them to target the most popular code libraries.

“TeamPCP has stated the competition is a recruiting opportunity and they intend to purchase all meaningful access harvested from participants’ campaigns,” the security firm Dataminr wrote. “The $1,000 XMR (Monero) prize is a recruitment floor and has been dismissed by the actor as ‘just like participation trophy,’ adding ‘if you find something good you will be paid way more,’ confirming the contest’s true function as talent identification and malicious access acquisition at scale.”

In March, TeamPCP executed a supply chain attack targeting AI infrastructure by compromising the code for LiteLLM, an open source AI gateway that connects users to more than 100 different large language models. A recent analysis by the security firm CloudSEK found TeamPCPs attack on LiteLLM harvested cloud service keys and other secrets from more than 2,500 organizations, including many of the world’s top technology companies.

In May, TeamPCP claimed credit for compromising at least 3,800 code repositories at the Microsoft-owned GitHub, after a GitHub developer installed a code extension that was compromised by TeamPCP’s malware.

MEET THE CYBERCATS

Security experts say TeamPCP is less of a hacker group than an amalgamation of threat actors from multiple cybercriminal gangs who sometimes work together toward similar goals.

“It is not a structured criminal crew with a single operator,” said Austin Larsen, a principal threat analyst with the Google Threat Intelligence Group. “It is a peer community of individually-skilled actors, with one clear center of gravity.”

That center of gravity is George Prepakis, an accomplished security researcher and self-described exploit developer who operates the Twitter/X profile @kernelstub. Earlier this year, @kernelstub tweeted a public invite link to a Matrix chat server he created and dubbed “Cybercats,” and TeamPCP and several other cybercrime entities have been using this server to communicate daily for the past several months.

Kernelstub, like other administrators in the Cybercats chat, has been using his Twitter/X profile name as his handle in these Matrix communications, frequently tweeting references to other members and to conversations taking place in the Cybercats chat. In a number of cases, the corresponding X accounts for members of the Cybercats chat taunted cybercrime victims publicly before the incidents were reported in the news media.

The Cybercats administrator listed at the top of the screenshot above — “Boxturtle” — is a close associate of TeamPCP who has been tweeting about the group’s conquests under the name @xpl0itrsturtle. This handle corresponds to a data breach broker active on Breachforums and Darkforums who has been selling data stolen in a wave of recent breaches at automobile manufacturers, including BMW Group, Audi, Honda, Mercedes-Benz, Volvo and Toyota, as well as data allegedly taken from Snapchat and SportRadar.

The Cybercats administrator “SeesawSec” in the screenshot above is the alias of whoever is behind the cybercrime group known as Fulcrumsec, which recently claimed credit for data extortion attacks against the pharmaceutical giant Novo Nordisk, the data broker LexisNexis, and Avnet, a Fortune 500 distributor of electronic components.

The Cybercats administrator “@pcpcasper” also has been using a similar name on X to discuss TeamPCP’s attacks and victims. This person has an extensive message history on Telegram, where their messages and shared videos show @pcpcasper is an active and vocal member of the National Socialist Network, a neo-Nazi political organization based in Australia.

At one point in these chats, @pcpcasper shared videos and images of what they claimed was their cat, and several of those videos place this user in Western Australia. One source close to the investigation told KrebsOnSecurity that @pcpcasper was one of the two arrested, a claim supported by messages that @kernelstub posted online this morning.

The Cybercats member roster pictured above also features an administrator with the username “T,” which is short for the now-banned Twitter/X profile @pcpcats, the account operated by the self-described TeamPCP spokesperson who was arrested today. As we’ll see in a moment, @pcpcats also is from Western Australia.

By the time @kernelstub tweeted a public invite link to the Cybercats Matrix server, T/@pcpcats was posting only infrequently to the group chat, with other members often inquiring as to his whereabouts and well-being. The group’s collective concern related to @pcpcats’s tendency to blame his increasingly extended absences on the use of hallucinogens and other narcotics that kept him awake for days on end, but also caused him to crash in bed for several days after the highs wore off.

WHO IS THE TEAMPCP LEADER?

The Cybercats member @pcpcats has used multiple nicknames on the cybercrime forums, including EllisD25/LSD on Darkforums, BulkDMT on Breachstars, and Express on Breachforums. These accounts are linked because they all advertised the same Tox ID and/or Session ID as instant message contact handles in their cybercrime forum posts. BulkDMT was also known on the forums as DMT Host, which was a virtual private server (VPS) hosting service that was peddled on Darkforums and Breachstars.

According to the cyber intelligence firm Intel 471, Express registered on Breachforums using the email address shitstickpp@gmail.com. Intel 471 finds Express posted on Breachforums across a two-month period in 2025 using four different Internet addresses located in South Africa. On July 30, 2025, Express announced on Breachforums they were selling access to 14 gigabytes of data stolen from South Africa’s State Information Technology Agency.

The threat intelligence platform Flashpoint recorded more than a year’s worth of messages from the TeamPCP leader’s alter ego on Telegram — Persy_PCP —  who claimed they split their life living between two countries [full disclosure: Flashpoint is an advertiser on this blog]. “I have these [files] as well, problem is these are in another country,” Persy_PCP explained to another user inquiring about a stolen data set in November 2025.

Later that month, Persy_PCP complained, “My whole country is racist and they want people like me dead.” Flashpoint records show BulkDMT shared in September 2025 that “this country is going to fucking starve when they take the farmers land,” a likely reference to white landowners in South Africa who claim to be targeted by an ongoing genocide campaign.

This tracks with public reporting on TeamPCP. Cyberscoop reported in June that Google had traced TeamPCP’s residential and mobile Internet address connections to South Africa, “indicating the primary operator was located there during at least some of its attacks.”

BulkDMT also shared on the group chat at Breachforums that they were recovering from an addiction to methamphetamine. “My life is kinda fucked rn [right now], but that’s fine and there isn’t really a point in pouring so much emotional energy into that fact, my parents had money but I unfortunately got really addicted to some things so I don’t get to benefit from that. As long as I continue to survive, stay sober, and move closer towards my goals that’s enough drive and meaning.”

The identity threat protection company SpyCloud finds shitstickpp@gmail.com shows up in the registration of an account called ChristmasSnow on the cybercrime community Raidforums in 2022. Nearly all of the Internet addresses used to access that account came from ISPs in Perth, Australia, SpyCloud found.

KrebsOnSecurity looked up all of those Perth IP addresses in passive DNS records maintained by DomainTools.com, and found one of them — 211.27.196.111 — for several years was used as a private file server by a family in Perth with the last name of Thomson. Those records show at least three hosts — ithomson.direct.quickconnect.to (a remote Synology server), kthomson0061.direct.quickconnect.to, and joshuawthomson39.myqnapcloud.com (a QNAP network storage device) — persisted at that address between 2022 and 2025.

Searching on “joshuathomson39” in the breach tracking service Constella Intelligence reveals an account at the freight forwarding company kwe.com created in the name of Joshua Thomson from Perth, Australia. The open source intelligence platform Epieos finds the phone number attached to that kwe.com account was used to register a Facebook profile for Josh Thomson, which says his family includes a brother named Ruben, his father Ian, and his mom Cindy.

That Facebook profile also says Josh and his family are originally from Pietermaritzburg, in KwaZulu-Natal, South Africa, but currently living in Cottesloe, a beach-side suburb of Perth. A search in DomainTools for Ian Thomson and Australia unearthed five domains by the same registrant, including securecomputing.au, thomson.org.au, and thomsonfamily.net.au. Ian Thomson is a dentist in Cottesloe, and a biography says he graduated from The University of the Witwatersrand in Johannesburg, South Africa.

Constella finds a joshua@thomson.org.au registered a number of accounts online, but Josh doesn’t seem to have much of a connection to dodgy cybercrime forums. His brother Ruben, on the other hand, has quite the presence on these communities, dating back to at least 2018. Constella reports ruben@thomson.org.au frequently reused the password “joshuathomson1,” and Constella further finds that password was used by just a handful of accounts, including yolosolo17@gmail.com and surfinup8@gmail.com.

According to Intel 471, surfinup8@gmail.com was used to register the user Yolosolo17 on the crime forum Altenen in 2018, and that user account was registered from the Perth address 110.141.230.15. On Altenen, Yolosolo17 advertised free web proxies, as well as the domain rubenthomson.com, which was at one point used to sell steeply discounted iPhones. DomainTools says rubenthomson.com was hosted at 110.141.230.15 and registered to surfinup8@gmail.com.

SpyCloud reports 10.141.230.15 was used by the email address sheepstealing@gmail.com on Raidforums and surfinup8@gmail.com on Nulled, and that the same IP was used by the email addresses ian@thomsonfamily.net.au, jasper@yakuza.cc, and rubenthomson1@gmail.com. SpyCloud also shows that sheepstealing Gmail address is tied to the accounts Sheep420, YoloSolo117 and Yakuza.cc on Raidforums, and to the account “Sheep Stealing” on Hackforums. Intel 471 says sheepstealing@gmail.com was used to register the account DingoFlour on Breachforums in October 2023, as well Sheepx on Altenen.

Epieos reports that ruben@securecomputing.au is tied to an Airbnb account for Ruben, who described himself as a Web developer who went to school at the University of Western Australia and was living outside the country. “Hey, I’m Ruben, my friends call me Ellis. I’m a Perth creative who occasionally books rooms when visiting family and for photography.”

Epieos also finds sheepstealing@gmail.com registered an upwork.com profile under the name Ruben, who said his main skills are setting up secure server hosting solutions and PHP full-stack Web development.

“I’m familiar with Linux, working with relational databases (SQL),” the Upwork profile reads. “I also script in Python mainly for writing social media bots.”

Epieos further discovered sheepstealing@gmail.com is connected to a Microsoft account for Ruben Thomson, and to a now-defunct GitHub account called XmasSnow/XmasSnowisBack that scammed people on the forums in 2022 by claiming to sell exclusive exploits for recently-released software patches (recall that shitstickpp@gmail.com was used to register a forum account named ChristmasSnow).

This same sheepstealing email address registered a Twitter/X account in 2026 called “Gone Fishing” that lists its location as South Africa. That Gmail account also left several reviews for businesses listed on Google Maps over the past seven years, but all of those establishments are located on the west coast of Australia.

The people search service Pipl finds a 21-year-old Ruben Thomson in Western Australia who has a phone number ending in 979. A lookup on that number at Epieos reveals it is connected to a TikTok account under the name Ellis, and to a PayPal account in the name of Ruben Thomson.

Finally, a search on the name Ruben Thomson from Cottesloe at the Australian government’s record of registered businesses finds he has incorporated or served as an official in multiple companies created since 2024, including Secure Computing Solutions, Tensor Industries, and another entity ironically named OPSEC Express. Recall that Express was BulkDMT’s nickname on Breachforums.

It’s ironic because OPSEC is short for the term “operational security,” which refers to techniques and behaviors used to obfuscate and compartmentalize one’s real-life identity online, and using your cybercrime handle as part of your own company name is very much the antithesis of that practice.

There is at least one other major opsec failure by Ruben that exposed a link to TeamPCP. In June 2025, someone using the name Ruben Thomson registered on HackerOne, a popular “bug bounty” program that seeks to reward and recognize researchers who agree to work with affected software vendors to help fix the flaws before publishing about their findings. What was Ruben Thomson’s chosen HackerOne username? Deadcatx3, a nickname that has been flagged by multiple security firms as an alias used by TeamPCP.

INTERVIEW WITH ELLIS

In early July 2026, not long after having discovered clues about Ellis’s real life identity, KrebsOnSecurity interviewed the TeamPCP leader via Signal, where he was remarkably open about his activities and personal struggles [for the sake of simplicity, the TeamPCP spokesperson will be referred to from here on as Ellis].

Ellis claims he stopped doing cybercrime for TeamPCP in March 2026 — just before the attacks that compromised LiteLLM — and that at least one other individual has taken over the group’s leadership since then. Ellis shared that a year earlier he had just completed the latest in a series of detox and sobriety programs, and was two months sober when he reconnected with some old friends from the malware development scene.

“One year ago I needed help monetizing some [GitHub credentials], I was two months sober and needed a distraction and something to keep busy as well as people to speak to,” Ellis said. “I had largely disconnected from my old circle, they had become very toxic and I needed to get away from the substances. Previously I had done some mass exploitation campaigns and grew up doing [malware development] and [capture the flag] contests. There were some friends who were also vending but had stopped a while, and one of them introduced me to some chats where I posted access for sale.”

Prior to that, Ellis said, he was homeless and hopping between “some very unstable places.”

“Blackhatting is fun,” he said. “There are actual rewards and incentives to learn and you grow with your team. Without qualifications, no employer will even take the time to hear you out.”

Ellis claims he’s earned a grand total of about $20,000 for his activities with TeamPCP, and that it was never about the money or fame for him. Asked whether his experiences with TeamPCP might prepare him for gainful employment in a legitimate IT job, Ellis said he doubted it.

“I am nowhere close to a skill level where I am comfortable, and this would take maybe half a decade of further experience,” he said. “I no longer have to choose between rent and food for that I’m grateful and so are the team members.”

Ellis expressed no remorse over his cybercrime activities, and said he was grateful for the friendships and relationships built throughout his engagement with TeamPCP. The young hacker also seemed resigned to his fate, and told KrebsOnSecurity that he’ll accept the consequences if he’s ever arrested.

“If I’ve already been found out then its out of my control, I’ll make peace with that,” he said. “Honestly, I think someone like me needs a lot of help that prison just can’t provide. If I had the funds to study different parts of the field and closer guidance, this would have turned out differently. But that’s a pipe dream and we both know this.”

It is clear from reading Ellis’s posts to the group’s Matrix server chats that his struggles with sobriety are ongoing. On Thursday, June 25, Ellis told @kernelstub he was about to “trip” with his “homie.”

“What kind,” @kernelstub inquired.

“Ketty and some DMT,” Ellis replied, referring to the dissociative anesthetic ketamine and dimethyltryptamine (DMT), a powerful psychedelic compound that is found naturally in some plants but is also synthetically produced in underground lab environments. “There’s a little 2cb so we might throw that in the mix,” he continued, referring to another psychedelic compound by its chemical shorthand.

Roughly two weeks before his arrest, Ellis told KrebsOnSecurity he was ready to leave his life of crime behind and was prepared to turn himself in, but that in the meantime he was making plans to tie up loose ends.

Less than 24 hours later, the TeamPCP leader posted an image on Telegram showing a yellowish powdered substance in a baggie and on a scale, possibly synthetic DMT. The image shows the powder being weighed next to a series of small vape cartridges, two of which are open on the table in front of the photographer.

The two defendants were arrested Wednesday morning. The AFP said the men face a combined 14 cybercrime offenses and are scheduled to appear in Perth Magistrates Court today.

Charlie Eriksen is a security researcher at Aikido Security who has closely followed TeamPCP’s cybercrime campaigns. Eriksen said TeamPCP are a good example of a new kind of threat actor that does not fit neatly into the usual categories.

“They are not a state actor, not quite organized cybercrime, and not purely ideological,” he said. “Their motivations seem to mix money, disruption, attention, and ideology.”

Eriksen said that historically there has always been a meaningful gap between reading about an attack technique and being able to reliably turn it into an operational campaign, but that large language models (LLMs) and artificial intelligence increasingly are helping threat actors to bypass that knowledge gap.

“You had to understand the research, adapt the code, troubleshoot it, build infrastructure around it, and then repeat that process across different targets,” he said. “LLMs have compressed that gap significantly.”

According to Eriksen, this creates an environment where threat actors suddenly have the ability to operate at significant scale without having developed the operational discipline that traditionally accompanies that level of capability. Put another way, it sets the stage for cybercriminals who are capable enough to cause significant damage, but not necessarily careful enough to understand or care about the consequences.

“They can be noisy, they can make mistakes,” he said. “They can leave evidence everywhere. They can take risks that a professional criminal group or intelligence service would consider completely unacceptable. But that does not necessarily make them less dangerous. In some ways, it can make them more dangerous.”

In a recent blog post, Eriksen called TeamPCP’s Shai-Hulud worm the “best thing to happen to supply chain security,” because it forced GitHub and other public coding platforms to erect new security safeguards.

In direct response to TeamPCP’s broad success at pushing poisoned versions of popular software packages, GitHub in late July introduced a three-day “cooldown” mechanism for Dependabot, the platform’s tool for auto-fetching newly shipped updates for any package dependencies. Cooldown periods are designed to help buy time for security tools and package maintainers to identify and remove any compromised versions. Other coding ecosystems like Python and various JavaScript platforms also added support for cooldown periods this year amid growing calls from security experts about the need for more widespread adoption of the safety feature.

Eriksen said TeamPCP’s legacy is that they achieved in the span of a few months what the supply chain security community has been unable to do for years.

“They managed to wake up Microsoft to the fact that they had become negligent in terms of security,” Eriksen said. “By compromising GitHub and stealing their source code, they humiliated Microsoft into action, making them finally act on what we had been asking them to do and take seriously for a while now.”

Update, 10:08 a.m. ET: A story this morning from ABC News in Australia confirms Ruben Ian Thomson of Cottesloe was one of the two arrested. The 23-year-old suspect thought to be @pcpcasper, Michael Gaebler, also was arrested in Perth. ABC News reports that Thomson was denied bail (Mr. Gaebler’s attorney reportedly did not request bail for his client), and that both men will be held in custody until their next court appearance on September 18.

The UK’s data protection watchdog has fined a nuisance call blocking biz £190,000 ($258,000) for bombarding elderly people with hundreds of thousands of - you guessed it - nuisance calls. Elderly Aids Ltd made 758,053 unsolicited direct marketing calls between May 27, 2024, and February 10, 2025, according to the Information Commissioner’s Office (ICO). On average, that works out as 2,916 calls per day. Busy fingers. The ICO and Telephone Preference Service (TPS), a UK service to register one’s phone number to exclude it from unwanted marketing calls, received 20 complaints during this timeframe related to Elderly Aids. It is illegal for direct marketers to call a number registered with the TPS, unless the individual has given explicit consent to that specific company to call them. All 758,053 unsolicited direct marketing calls, in this case, were made to phone numbers registered with the TPS and belonged to people who had not given their consent for Elderly Aids to contact them. Complainants commonly cited aggressive and misleading sales tactics, with callers also failing to identify themselves. One said their father was pressured into signing up to Elderly Aids’ services, which required a £139 ($188) sign-up fee, and a recurring monthly £6.99 ($9.50) payment on top of this. Andy Curry, head of investigations at the ICO, said: “Not only did this company target vulnerable people who had explicitly asked not to be called – they harassed them to sell call-blocking devices. “EAL showed a complete disregard for the law and the people they were hounding. This penalty should serve as a clear warning to any business that thinks the law does not apply to them - we will hold them to account for both exploiting people in this way and trying to avoid accountability.” Russell Roach, director of preference services at the Data & Marketing Association (DMA), concurred and encouraged responsible businesses to screen their calling lists against the TPS and Corporate TPS (CTPS) registers. “People register with the Telephone Preference Service because they want greater control over who can contact them,” he said. “Cases like this demonstrate why those protections are so important. “Anyone making live marketing calls must respect the choices people have made about their privacy. When organizations ignore those preferences and contact individuals who have explicitly opted out of receiving unsolicited sales calls, particularly those who are most vulnerable, they undermine consumer trust and risk causing significant nuisance and distress.” The ICO said Elderly Aids failed to engage with the regulator, ignoring requests for information, while continuing to make illegal marketing calls. According to public Companies House filings, the company attempted to strike itself off the register three months after it started pestering the elderly with its phone calls, although this was swiftly suspended following an objection. The ICO said that in cases where a debtor cannot pay a fine, such as those in “genuine financial hardship,” they provide payment plans. Organizations that can pay don’t face formal recovery action, and when directors attempt to skirt fines through insolvency, insolvency practitioners are called in, potentially kickstarting a multi-year recovery process. ®

The FBI on Wednesday said it disrupted a botnet and seized two platforms that Chinese-government cyberoperatives used to hack NASA, the US Senate, the Department of Energy, and several other government agencies and critical networks. The Federal Reserve, Department of Justice, Department of Health and Human Services, and the National Institutes of Health were also among those victimized by the two now-seized hacking tools: a vulnerability scanning and exploitation malware named QScan, and an obfuscation network named QTRouter. The FBI says a People’s Republic (PRC) of China-backed group called QTFY created and operated the two platforms, plus botnets of compromised IoT devices. The Bureau says QTFY’s hackers work for a private PRC company called Nanjing Xinjiuwei. “Payments from the PRC's Ministry of State Security (MSS) to Nanjing Xinjiuwei, for example, indicate that the company conducts malicious cyber activities on behalf of the PRC Government,” according to court documents. “QTFY actors include former members of the PRC's People's Liberation Army (PLA), and they use their PLA relationships to obtain contracts and subcontracts supporting offensive cyber operations,” the documents state. How to build a botnet QScan scans and automatically infects thousands of IoT devices worldwide, and then adds them to the QTRouter network of QTFY-controlled devices. The QTRouter botnet – consisting of these compromised IoT devices, plus commercial proxy service devices, and leased virtual private servers – then serves as an obfuscation network, allowing QTFY and other criminals who pay for the service to conceal the origin of their digital intrusion activities, making these communications appear to originate from local computers. On Monday, a US federal court granted seizure warrants for three domains linked to QTFY: qtproxy.xyz, qt-proxy.org, and qt-team.com. All three domains were hardcoded into both the QScan and QTRouter malware, and the court-authorized seizures made both hacking services inoperable, the Justice Department said. Hacking critical networks since 2018 (at least) The hacking services and malware have been in use since at least 2018, and as recently as this year when QTFY infrastructure compromised the US Senate, according to court documents. The FBI investigated an attempted computer intrusion at NASA in August 2019, during which the Chinese government snoops tried to exploit CVE-2019-11510, a critical vulnerability in Ivanti’s Pulse Secure VPN that allowed attackers to learn legitimate users' usernames and passwords, effectively granting them unauthorized access to protected networks. Ivanti patched the flaw in April 2019. As The Register previously reported, China also abused this bug as a zero-day to break into dozens of defense companies, government agencies, and financial organizations in America and abroad. QTFY later exploited this same CVE in 2020 during the COVID-19 pandemic to attack a medical center in Ohio, according to court documents. Other victims in 2019 and 2020 include unnamed financial groups in Michigan and South Korea, and a Missouri insurance agency. The insurance agency attack abused a different vulnerability: CVE-2019-19781, a critical flaw in Citrix VPN products that allowed arbitrary code execution with no account credentials. Years later, in 2024, QTFY hackers also broke into computers at three DOE National Laboratories, NIH, and a US security device manufacturer. “These entities were victims of a zero-day attack against Ivanti Cloud Services Appliance,” the court documents say. The FBI did not respond to The Register’s inquiries, including how many computers QTFY compromised, and whether the crew has ties to any of China’s "Typhoon" groups. PRC goon squad whac-a-mole This latest disruption follows a series of court-ordered seizures intended to hamstring China’s hacking activities over the last few years. In 2025, the FBI removed PlugX surveillance malware from more than 4,000 US computers that had been infected by the PRC-sponsored group Mustang Panda. A year earlier, in 2024, China’s Flax Typhoon burned down their own botnet consisting of hundreds of thousands of infected internet-of-things devices when confronted by the feds. And in late 2023, the FBI disrupted a botnet used by yet another Chinese government attack crew, Volt Typhoon, to attack US and foreign critical infrastructure. In June, however, Lumen’s Black Lotus Labs reported a “significant resurgence” of a botnet linked to Volt Typhoon, with this cluster of injected machines surging to 1,500 compromised routers and IoT devices.®

OpenAI has published its technical report detailing "the Hugging Face incident," the compromise of the eponymous LLM repository by unreleased, ill-supervised AI models. The incident, widely reported, has prompted concern among technical types, the public, and lawmakers about how automated software was able to escape containment and hack an external organization, and about what can be done to prevent similar incidents. OpenAI's explanation addresses what happened, but its call for keeping a closer watch on AI activities won't elicit much enthusiasm. "The incident occurred during cybersecurity evaluations of several OpenAI models, and was primarily driven by a highly capable, internal-only research model comparable in scale to GPT‑5.6 Sol," the company said in a blog post. "The models, operating under reduced safeguards, took actions that were misaligned with the goals of their assigned tasks – they communicated through unauthorized channels, exploited vulnerabilities in shared infrastructure, gained internet access, and accessed third-party systems." The incident became the subject of discussion at the Black Hat security conference and elsewhere. The basic storyline begins with a notionally sandboxed AI agent trying to solve an impossible task in ExploitGym, a security benchmark test. Unable to complete the challenge, the agent explored its environment to find ways to make progress toward its goal. It figured out that it could communicate with other AI agents by using Artifactory, an internal package management system, as a message board. The agents then collaborated with each other to cheat on various ExploitGym tasks. The machine learning models eventually identified a server-side request forgery (SSRF) zero-day vulnerability in Artifactory's code and used that to gain internet access. They subsequently found exposed Hugging Face credentials. The agents then used those credentials to find and chain several security exploits that gave them full code execution on several Hugging Face servers, all in the hope of finding information to solve the ExploitGym task. "Ultimately, agents powered either by the internal-only research model, or by GPT-5.6, executed code on 41 Hugging Face production dataset server workers, obtained root access on at least one production node, accessed Hugging Face production credentials and limited internal data, and downloaded four private Hugging Face code repositories," OpenAI's technical report [PDF] explains. The details are fascinating and troubling, more so because Anthropic's and Meta's models have also acted in ways that would constitute a crime if a human took the same actions. The ChatGPT-maker identified four misalignment patterns that made things go awry: "reward hacking, persistence on seemingly impossible tasks, unauthorized communication, and agents adopting goals from one another." OpenAI has already taken steps to shore up its security, which was relaxed for its model testing. The company says it's trying to improve security and monitoring to mitigate alignment issues like how models cheat, behave when given impossible tasks, and how alignment can be maintained while multiple agents work, including over long-duration tasks. But the central issue is not that machine learning software armed with tools and a task will try every possible option, even ones its programmers failed to consider. The problem, as OpenAI acknowledges, is that people don't watch over their AI agents at all times. "We are taking this incident as a 'warning shot' that today’s model capabilities present the possibility of loss-of-control incidents," the AI biz said. "Companies that build AI systems will need to ensure that their systems always remain under meaningful human control, and that meaningful safeguards constrain their ability to cause harm." Throughout the tech industry, companies like Anthropic, AWS, Google, OpenAI, Microsoft, and Salesforce talk about "autonomous agents." But agents are no longer autonomous under persistent, meaningful human control. ®

The AI giant acknowledges that it could have done far more to prevent its AI agents from going rogue. But it still fails to explain why it didn't see this fiasco coming.

China’s hacking campaign targeted NASA, the Federal Reserve, the US Senate, the Justice Department, and more, according to the DOJ.

Medical device maker Boston Scientific’s global operations have been disrupted by an ongoing cyberattack, the company disclosed on Wednesday. According to an SEC filing, the “cybersecurity incident” affecting its IT systems started on Tuesday, and resulted in a “global disruption to the company’s operations.” Upon detecting the digital intruders, the company began an investigation with third-party infosec experts who are working to contain the threat, the filing says. The medtech firm did not immediately respond to The Register’s inquiries, including if this was a ransomware infection and what data, if any, the criminals stole after breaking into the IT systems. “The incident has caused, and is expected to continue to cause, disruptions and limitations of access to certain of the company’s information systems and business applications that support aspects of the Company’s operations, including the ability to process and ship customer orders,” Boston Scientific reported to federal regulators. The company doesn’t have a timeline for full restoration, and noted the “full scope, nature and impacts, including operational and financial impacts” of the cyberattack remain unknown. The news did, however, send Boston Scientific shares spiraling down more than 4% on Wednesday morning. At press time, none of the usual suspects had claimed responsibility for the attack. In recent months, both ransomware/extortion gangs and government-backed hackers have disrupted other medtech firms’ operations and stolen sensitive data. In March, Stryker was hit by a cyber crew with ties to Iran's intelligence agency, causing a global network outage at the company. A month later, medical-device maker Medtronic disclosed a cyberattack in a filing with federal regulators. Notorious data-theft-and-extortion group ShinyHunters claimed to be behind this intrusion, and the company in July warned patients that their names, contact details, dates of birth, Social Security numbers, and health information was stolen in the breach. ®

Workwear and fashion retailer Carhartt’s data breach was about half as bad as ShinyHunters claimed, according to Troy Hunt, who reviewed the data dump before uploading it to his Have I Been Pwned website. Hunt’s HIBP service reported 12.9 million individuals affected by the alleged breach, around half of what ShinyHunters purported when it claimed to leak the company’s data earlier this month. ShinyHunters dumped what it said was 50GB worth of Carhartt’s data on August 13 after the retailer hired what the criminals called “a very unskilled and incompetent negotiator” to haggle the crooks down from their $3.3 million extortion demand. According to Hunt, ShinyHunters data was injected with millions of lines of synthetic data, substantially padding out the number of affected individuals. “You're not going to believe this, but turns out you can't always take criminals at their word,” said Hunt, before detailing the investigative process that goes into calculating the scale of breaches that make it to the HIBP site. Hunt usually starts with HIBP's open-source email address extractor, which spat out nearly 25 million addresses, before running it through OpenClaw to analyze the contents further and sift through the mass of information, looking for anomalies. For a retailer, the AI thought that the millions of .edu and .org email domains looked off - like signs of TPC-DS synthetic data injection. Examples included michael.ware@c.edu and michelle.larue@lkvb06fkzsjv.org. The first and last names look real, but a common finding among TPC-DS-generated data is that it will use completely random strings for domains. A manual look at the data points with which these email addresses were associated further revealed these "individuals" were located in countries, such as Benin, which don’t represent dominant Carhartt markets. Further, the AI found more customers registered in Montenegro than in the US, where Carhartt is headquartered. It also found a suspiciously large proportion of customers with birth dates set in the early 1900s – unlikely given the company’s clientele is more hipster-oriented than than blue-collar nowadays. Hacking away at all the clearly bogus data, OpenClaw dropped the estimated number of genuine individuals among the data trove from 24.8 million to 13.6 million. Hunt carried on eliminating suspicious findings he noticed, such as Microsoft 365 duplicate email addresses and addresses marked for deactivation, as well as prompting OpenClaw to continue doing the same. He finally arrived at 12,933,413 accounts believed to be genuine among the ShinyHunters-leaked dataset. That’s the number that made it to the HIBP platform, which states that 83 percent of these were already gathered up in previous breaches. The moral of the story is, as Hunt says, to “take headline numbers with a grain of salt unless you're confident in the processes of those making the claims." And until trustworthy sources do the arduous work, stop treating the word of cybercriminals as gospel. The real data contains names, email addresses, phone numbers, and physical addresses. Carhartt did not respond to our request for comment on Hunt’s findings. The company is yet to comment on the breach anywhere publicly. ®
