U.S. state and federal investigators are being inundated with reports from people who’ve lost hundreds of thousands or millions of dollars in connection with a complex investment scam known as “pig butchering,” wherein people are lured by flirtatious strangers online into investing in cryptocurrency trading platforms that eventually seize any funds when victims try to cash out.
The term “pig butchering” refers to a time-tested, heavily scripted, and human-intensive process of using fake profiles on dating apps and social media to lure people into investing in elaborate scams. In a more visceral sense, pig butchering means fattening up a prey before the slaughter.
“The fraud is named for the way scammers feed their victims with promises of romance and riches before cutting them off and taking all their money,” the Federal Bureau of Investigation (FBI) warned in April 2022. “It’s run by a fraud ring of cryptocurrency scammers who mine dating apps and other social media for victims and the scam is becoming alarmingly popular.”
As documented in a series of investigative reports published over the past year across Asia, the people creating these phony profiles are largely men and women from China and neighboring countries who have been kidnapped and trafficked to places like Cambodia, where they are forced to scam complete strangers over the Internet — day after day.
The most prevalent pig butchering scam today involves sophisticated cryptocurrency investment platforms, where investors invariably see fantastic returns on their deposits — until they try to withdraw the funds. At that point, investors are told they owe huge tax bills. But even those who pay the phony levies never see their money again.
The come-ons for these scams are prevalent on dating sites and apps, but they also frequently start with what appears to be a wayward SMS — such as an instant message about an Uber ride that never showed. Or a reminder from a complete stranger about a planned meetup for coffee. In many ways, the content of the message is irrelevant; the initial goal to simply to get the recipient curious enough to respond in some way.
Those who respond are asked to continue the conversation via WhatsApp, where an attractive, friendly profile of the opposite gender will work through a pre-set script that is tailored to their prey’s apparent socioeconomic situation. For example, a divorced, professional female who responds to these scams will be handled with one profile type and script, while other scripts are available to groom a widower, a young professional, or a single mom.
That’s according to Erin West, deputy district attorney for Santa Clara County in Northern California. West said her office has been fielding a large number of pig butchering inquiries from her state, but also from law enforcement entities around the country that are ill-equipped to investigate such fraud.
“The people forced to perpetrate these scams have a guide and a script, where if your victim is divorced say this, or a single mom say this,” West said. “The scale of this is so massive. It’s a major problem with no easy answers, but also with victim volumes I’ve never seen before. With victims who are really losing their minds and in some cases are suicidal.”
West is a key member of REACT, a task force set up to tackle especially complex forms of cyber theft involving virtual currencies. West said the initial complaints from pig butchering victims came early this year.
“I first thought they were one-off cases, and then I realized we were getting these daily,” West said. “A lot of them are being reported to local agencies that don’t know what to do with them, so the cases languish.”
West said pig butchering victims are often quite sophisticated and educated people.
“One woman was a university professor who lost her husband to COVID, got lonely and was chatting online, and eventually ended up giving away her retirement,” West recalled of a recent case. “There are just horrifying stories that run the gamut in terms of victims, from young women early in their careers, to senior citizens and even to people working in the financial services industry.”
In some cases reported to REACT, the victims said they spent days or weeks corresponding with the phony WhatsApp persona before the conversation shifted to investing.
“They’ll say ‘Hey, this is the food I’m eating tonight’ and the picture they share will show a pretty setting with a glass of wine, where they’re showcasing an enviable lifestyle but not really mentioning anything about how they achieved that,” West said. “And then later, maybe a few hours or days into the conversation, they’ll say, ‘You know I made some money recently investing in crypto,’ kind of sliding into the topic as if this wasn’t what they were doing the whole time.”
Curious investors are directed toward elaborate and official-looking online crypto platforms that appear to have thousands of active investors. Many of these platforms include extensive study materials and tutorials on cryptocurrency investing. New users are strongly encouraged to team up with more seasoned investors on the platform, and to make only small investments that they can afford to lose.
The now-defunct homepage of xtb-market[.]com, a scam cryptocurrency platform tied to a pig butchering scheme.
“They’re able to see some value increase, and maybe even be allowed to take out that value increase so that they feel comfortable about the situation,” West said. Some investors then need little encouragement to deposit additional funds, which usually generate increasingly higher “returns.”
West said many crypto trading platforms associated with pig butchering scams appear to have been designed much like a video game, where investor hype is built around upcoming “trading opportunities” that hint at even more fantastic earnings.
“There are bonus levels and VIP levels, and they’ll build hype and a sense of frenzy into the trading,” West said. “There are definitely some psychological mechanisms at work to encourage people to invest more.”
“What’s so devastating about many of the victims is they lose that sense of who they are,” she continued. “They thought they were a savvy, sophisticated person, someone who’s sort of immune to scams. I think the large scale of the trickery and psychological manipulation being used here can’t be understated. It’s like nothing I’ve seen before.”
Courtney Nolan, a divorced mother of three daughters, says she lost more than $5 million to a pig butchering scam. Nolan lives in St. Louis and has a background in investment finance, but only started investing in cryptocurrencies in the past year.
Nolan’s case may be especially bad because she was already interested in crypto investing when the scammer reached out. At the time, Bitcoin was trading at or near all-time highs of nearly $68,000 per coin.
Nolan said her nightmare began in late 2021 with a Twitter direct message from someone who was following many of the same cryptocurrency influencers she followed. Her fellow crypto enthusiast then suggested they continue their discussion on WhatsApp. After much back and forth about his trading strategies, her new friend agreed to mentor her on how to make reliable profits using the crypto trading platform xtb.com.
“I had dabbled in leveraged trading before, but his mentor program gave me over 100 pages of study materials and agreed to walk me through their investment strategies over the course of a year,” Nolan told KrebsOnSecurity.
Nolan’s mentor had her create an account website xtb-market[.]com, which was made to be confusingly similar to XTB’s official platform. The site promoted several different investment packages, including a “starter plan” that involves a $5,250 up-front investment and promises more than 15 percent return across four separate trading bursts.
Platinum plans on xtb-market promised a whopping 45 percent ROI, with a minimum investment of $265,000. The site also offered a generous seven percent commission for referrals, which encouraged new investors to recruit others.
The now-defunct xtb-market[.]com.
While chatting via WhatsApp, Nolan and her mentor would trade side by side in xtb-market, initially with small investments ranging from $500 to $5,000. When those generated hefty returns, Nolan made bigger deposits. On several occasions she was able to withdraw amounts ranging from $10,000 to $30,000.
But after investing more than $4.5 million of her own money over nearly four months, Nolan found her account was suddenly frozen. She was then issued a tax statement saying she owed nearly $500,000 in taxes before she could reactivate her account or access her funds.
Nolan said it seems obvious in hindsight that she should never have paid the tax bill. Because xtb-market and her mentor cut all communications with her after that, and the entire website disappeared just a few weeks later.
Justin Maile, an investigation partner manager at Chainalysis, told Vice News that the tax portion of the pig butchering scam relies on the “sunk costs fallacy,” when people are reluctant to abandon a failing strategy or course of action because they have already invested heavily in it.
“Once the victim starts getting skeptical or tries to withdraw their funds, they are often told that they have to pay tax on the gains before funds can be unlocked,” Maile told Vice News. “The scammers will try to get any last payments out of the victims by exploiting the sunk cost fallacy and dangling huge profits in front of them.”
Vice recently published an in-depth report on pig butchering’s link to organized crime gangs in Asia that lure young job seekers with the promise of customer service jobs in call centers. Instead, those who show up at the appointed place and time are taken on long car rides and/or forced hikes across the borders into Cambodia, where they are pressed into indentured servitude.
Vice found many of the people forced to work in pig-butchering scams are being held in Chinese-owned casinos operating in Cambodia. Many of those casinos were newly built when the Covid pandemic hit. As the new casinos and hotels sat empty, organized crime groups saw an opportunity to use these facilities to generate huge income streams, and many foreign travelers stranded in neighboring countries were eventually trafficked to these scam centers.
Vice reports:
“While figures on the number of people in scam centers in Cambodia is unknown, best estimates pieced together from various sources point to the tens of thousands across scam centers in Sihanoukville, Phnom Penh, and sites in border regions Poipet and Bavet. In April, Thailand’s assistant national police commissioner said 800 Thai citizens had been rescued from scam centers in Cambodia in recent months, with a further 1,000 citizens still trapped across the country. One Vietnamese worker estimated 300 of his compatriots were held on just one floor in a tall office block hosting scam operations.”
“…within Victory Paradise Resort alone there were 7,000 people, the majority from mainland China, but also Indonesians, Singaporeans and Filipinos. According to the Khmer Times, one 10-building complex of high-rises in Sihanoukville, known as The China Project, holds between 8,000 to 10,000 people participating in various scams—a workforce that would generate profits around the $1 billion mark each year at $300 per worker per day.”
REACTs’ West said while there are a large number of pig butchering victims reporting their victimization to the FBI, very few are receiving anything more than instructions about filing a complaint with the FBI’s Internet Crime Complaint Center (IC3), which keeps track of cybercrime losses and victims.
“There’s a huge gap in victims that are seeing any kind of service at all, where they’re reporting to the FBI but not being able to talk to anyone,” she said. “They’re filling out the IC3 form and never hearing back. It sort of feels like the federal government is ignoring this, so people are going to local agencies, which are sending these victims our way.”
For many younger victims of pig butchering, even losses of a few thousand dollars can be financially devastating. KrebsOnSecurity recently heard from two different readers who said they were in their 20s and lost more than $40,000 each when the investment platforms they were trading on vanished with their money.
The FBI can often bundle numerous IC3 complaints involving the same assailants and victims into a single case for federal prosecutors to pursue the guilty, and/or try to recapture what was stolen. In general, however, victims of crypto crimes rarely see that money again, or if they do it can take many years.
“The next piece is what can we actually do with these cases,” West said. “We used to frame success as getting bad people behind bars, but these cases leave us as law enforcement with not a lot of opportunity there.”
West said the good news is U.S. authorities are seeing some success in freezing cryptocurrency wallets suspected of being tied to large-scale cybercriminal operations. Indeed, Nolan told KrebsOnSecurity that her losses were substantial enough to warrant an official investigation by the FBI, which she says has since taken steps to freeze at least some of the assets tied to xtb-market[.]com.
Likewise, West said she was recently able to freeze cryptocurrency funds stolen from some pig butchering victims, and now REACT is focusing on helping state and local authorities learn how to do the same.
“It’s important to be able to mobilize quickly and know how to freeze and seize crypto and get it back to its rightful owner,” West said. “We definitely have made seizures in cases involving pig butchering, but we haven’t gotten that back to the rightful owners yet.”
In April, the FBI warned Internet users to be on guard against pig butchering scams, which it said attracts victims with “promises of romance and riches” before duping them out of their money. The IC3 said it received more than 4,300 complaints related to crypto-romance scams, resulting in losses of more than $429 million.
Here are some common elements of a pig butchering scam:
–Dating apps: Pig-butchering attempts are common on dating apps, but they can begin with almost any type of communication, including SMS text messages.
–WhatsApp: In virtually all documented cases of pig butchering, the target is moved fairly quickly into chatting with the scammer via WhatsApp.
–No video: The scammers will come up with all kinds of excuses not to do a video call. But they will always refuse.
–Investment chit-chat: Your contact (eventually) claims to have inside knowledge about the cryptocurrency market and can help you make money.
The FBI’s tips on avoiding crypto scams:
-Never send money, trade, or invest based on the advice of someone you have only met online.
-Don’t talk about your current financial status to unknown and untrusted people.
-Don’t provide your banking information, Social Security Number, copies of your identification or passport, or any other sensitive information to anyone online or to a site you do not know is legitimate.
-If an online investment or trading site is promoting unbelievable profits, it is most likely that—unbelievable.
-Be cautious of individuals who claim to have exclusive investment opportunities and urge you to act fast.
Ever hear of a crime called skimming? It may not be as dramatic a crime as assault or Ponzi schemes, but it can cause significant problems to you as your savings account can be wiped out in a flash.
Picture a scrawny nerd tampering with an automated teller machine (ATM)—the machine you use with your debit card to get cash. The thief places a device over the slot through which you slide your debit card. You have no idea it’s there. You swipe your card, and the device “skims” or reads your card’s information. In the middle of the night, the thief creeps back, removes the skimming device, downloads your data, burns it to a blank ATM card, makes a fat withdrawal and goes home with the loot. Or they could download your information from the skimmer and then use your information to make online purchases or access your account. Either way, they could clean you out before you wake up next morning!
Now, to be successful, the criminal not only needs a skimming device, they also need to attach a tiny wireless camera to capture your PIN. These cameras are usually concealed in the lighting fixture above the keypad, in a brochure near the machine, or attached directly to the ATM.
To protect yourself from being skimmed, and generally staying safe when using your debit or credit cards, follow these tips:
Stay safe from skimming!

The 911 service as it existed until July 28, 2022.
911[.]re, a proxy service that since 2015 has sold access to hundreds of thousands of Microsoft Windows computers daily, announced this week that it is shutting down in the wake of a data breach that destroyed key components of its business operations. The abrupt closure comes ten days after KrebsOnSecurity published an in-depth look at 911 and its connections to shady pay-per-install affiliate programs that secretly bundled 911’s proxy software with other titles, including “free” utilities and pirated software.
911[.]re is was one of the original “residential proxy” networks, which allow someone to rent a residential IP address to use as a relay for his/her Internet communications, providing anonymity and the advantage of being perceived as a residential user surfing the web.
Residential proxy services are often marketed to people seeking the ability to evade country-specific blocking by the major movie and media streaming providers. But some of them — like 911 — build their networks in part by offering “free VPN” or “free proxy” services that are powered by software which turns the user’s PC into a traffic relay for other users. In this scenario, users indeed get to use a free VPN service, but they are often unaware that doing so will turn their computer into a proxy that lets others use their Internet address to transact online.
From a website’s perspective, the IP traffic of a residential proxy network user appears to originate from the rented residential IP address, not from the proxy service customer. These services can be used in a legitimate manner for several business purposes — such as price comparisons or sales intelligence — but they are massively abused for hiding cybercrime activity because they can make it difficult to trace malicious traffic to its original source.
As noted in KrebsOnSecurity’s July 19 story on 911, the proxy service operated multiple pay-per-install schemes that paid affiliates to surreptitiously bundle the proxy software with other software, continuously generating a steady stream of new proxies for the service.
A cached copy of flashupdate[.]net circa 2016, which shows it was the homepage of a pay-per-install affiliate program that incentivized the silent installation of 911’s proxy software.
Within hours of that story, 911 posted a notice at the top of its site, saying, “We are reviewing our network and adding a series of security measures to prevent misuse of our services. Proxy balance top-up and new user registration are closed. We are reviewing every existing user, to ensure their usage is legit and [in] compliance with our Terms of Service.”
At this announcement, all hell broke loose on various cybercrime forums, where many longtime 911 customers reported they were unable to use the service. Others affected by the outage said it seemed 911 was trying to implement some sort of “know your customer” rules — that maybe 911 was just trying to weed out those customers using the service for high volumes of cybercriminal activity.
Then on July 28, the 911 website began redirecting to a notice saying, “We regret to inform you that we permanently shut down 911 and all its services on July 28th.”
According to 911, the service was hacked in early July, and it was discovered that someone manipulated the balances of a large number of user accounts. 911 said the intruders abused an application programming interface (API) that handles the topping up of accounts when users make financial deposits with the service.
“Not sure how did the hacker get in,” the 911 message reads. “Therefore, we urgently shut down the recharge system, new user registration, and an investigation started.”
The parting message from 911 to its users, posted to the homepage July 28, 2022.
However the intruders got in, 911 said, they managed to also overwrite critical 911[.]re servers, data and backups of that data.
“On July 28th, a large number of users reported that they could not log in the system,” the statement continues. “We found that the data on the server was maliciously damaged by the hacker, resulting in the loss of data and backups. Its [sic] confirmed that the recharge system was also hacked the same way. We were forced to make this difficult decision due to the loss of important data that made the service unrecoverable.”
Operated largely out of China, 911 was an enormously popular service across many cybercrime forums, and it became something akin to critical infrastructure for this community after two of 911’s longtime competitors — malware-based proxy services VIP72 and LuxSocks — closed their doors in the past year.
Now, many on the crime forums who relied on 911 for their operations are wondering aloud whether there are any alternatives that match the scale and utility that 911 offered. The consensus seems to be a resounding “no.”
I’m guessing we may soon learn more about the security incidents that caused 911 to implode. And perhaps other proxy services will spring up to meet what appears to be a burgeoning demand for such services at the moment, with comparatively little supply.
In the meantime, 911’s absence may coincide with a measurable (if only short-lived) reprieve in unwanted traffic to top Internet destinations, including banks, retailers and cryptocurrency platforms, as many former customers of the proxy service scramble to make alternative arrangements.
Riley Kilmer, co-founder of the proxy-tracking service Spur.us, said 911’s network will be difficult to replicate in the short run.
“My speculation is [911’s remaining competitors] are going to get a major boost in the short term, but a new player will eventually come along,” Kilmer said. “None of those are good replacements for LuxSocks or 911. However, they will all allow anyone to use them. For fraud rates, the attempts will continue but through these replacement services which should be easier to monitor and stop. 911 had some very clean IP addresses.”
911 wasn’t the only major proxy provider disclosing a breach this week tied to unauthenticated APIs: On July 28, KrebsOnSecurity reported that internal APIs exposed to the web had leaked the customer database for Microleaves, a proxy service that rotates its customers’ IP addresses every five to ten minutes. That investigation showed Microleaves — like 911 — had a long history of using pay-per-install schemes to spread its proxy software.
With the recent demise of several popular “proxy” services that let cybercriminals route their malicious traffic through hacked PCs, there is now something of a supply chain crisis gripping the underbelly of the Internet. Compounding the problem, several remaining malware-based proxy services have chosen to block new registrations to avoid swamping their networks with a sudden influx of customers.
Last week, a seven-year-old proxy service called 911[.]re abruptly announced it was permanently closing after a cybersecurity breach allowed unknown intruders to trash its servers and delete customer data and backups. 911 was already akin to critical infrastructure for many in the cybercriminal community after its top two competitors — VIP72 and LuxSocks — closed or were shut down by authorities over the past 10 months.
The underground cybercrime forums are now awash in pleas from people who are desperately seeking a new supplier of abundant, cheap, and reliably clean proxies to restart their businesses. The consensus seems to be that those days are now over, and while there are many smaller proxy services remaining, few of them on their own are capable of absorbing anywhere near the current demand.
“Everybody is looking for an alternative, bro,” wrote a BlackHatForums user on Aug. 1 in response to one of many “911 alternative” discussion threads. “No one knows an equivalent alternative to 911[.]re. Their service in terms of value and accessibility compared to other proxy providers was unmatched. Hopefully someone comes with a great alternative to 911[.]re.”
Among the more frequently recommended alternatives to 911 is SocksEscort[.]com, a malware-based proxy network that has been in existence since at least 2010. Here’s what part of their current homepage looks like:
The SocksEscort home page says its services are perfect for people involved in automated online activity that often results in IP addresses getting blocked or banned, such as Craigslist and dating scams, search engine results manipulation, and online surveys.
But faced with a deluge of new signups in the wake of 911’s implosion, SocksEscort was among the remaining veteran proxy services that opted to close its doors to new registrants, replacing its registration page with the message:
“Due to unusual high demand, and heavy load on our servers, we had to block all new registrations. We won’t be able to support our proxies otherwise, and close SocksEscort as a result. We will resume registrations right after demand drops. Thank you for understanding, and sorry for the inconvenience.”
According to Spur.us, a startup that tracks proxy services, SocksEscort is a malware-based proxy offering, which means the machines doing the proxying of traffic for SocksEscort customers have been infected with malicious software that turns them into a traffic relay.
Spur says SocksEscort’s proxy service relies on software designed to run on Windows computers, and is currently leasing access to more than 14,000 hacked computers worldwide. That is a far cry from the proxy inventory advertised by 911, which stood at more than 200,000 IP addresses for rent just a few days ago.

SocksEscort is what’s known as a “SOCKS Proxy” service. The SOCKS (or SOCKS5) protocol allows Internet users to channel their Web traffic through a proxy server, which then passes the information on to the intended destination. From a website’s perspective, the traffic of the proxy network customer appears to originate from a rented/malware-infected PC tied to a residential ISP customer, not from the proxy service customer.
These services can be used in a legitimate manner for several business purposes — such as price comparisons or sales intelligence — but they are massively abused for hiding cybercrime activity because they make it difficult to trace malicious traffic to its original source.
The disruption at 911[.]re came days after KrebsOnSecurity published an in-depth look at the long-running proxy service, which showed that 911 had a history of incentivizing the installation of its proxy software without user notice or consent, and that it actually ran some of these “pay-per-install” schemes on its own to guarantee a steady supply of freshly-hacked PCs.
More on SocksEscort in an upcoming story.

Sept. 1, 2021: 15-Year-Old Malware Proxy Network VIP72 Goes Dark
Email scammers sent an Uber to the home of an 80-year-old woman who responded to a well-timed email scam, in a bid to make sure she went to the bank and wired money to the fraudsters. In this case, the woman figured out she was being scammed before embarking for the bank, but her story is a chilling reminder of how far crooks will go these days to rip people off.
Travis Hardaway is a former music teacher turned app developer from Towson, Md. Hardaway said his mother last month replied to an email she received regarding an appliance installation from BestBuy/GeekSquad. Hardaway said the timing of the scam email couldn’t have been worse: His mom’s dishwasher had just died, and she’d paid to have a new one delivered and installed.
“I think that’s where she got confused, because she thought the email was about her dishwasher installation,” Hardaway told KrebsOnSecurity.
Hardaway said his mom initiated a call to the phone number listed in the phony BestBuy email, and that the scammers told her she owed $160 for the installation, which seemed right at the time. Then the scammers asked her to install remote administration software on her computer so that they could control the machine from afar and assist her in making the payment.
After she logged into her bank and savings accounts with scammers watching her screen, the fraudster on the phone claimed that instead of pulling $160 out of her account, they accidentally transferred $160,000 to her account. They said they they needed her help to make sure the money was “returned.”
“They took control of her screen and said they had accidentally transferred $160,000 into her account,” Hardaway said. “The person on the phone told her he was going to lose his job over this transfer error, that he didn’t know what to do. So they sent her some information about where to wire the money, and asked her to go to the bank. But she told them, ‘I don’t drive,’ and they told her, “No problem, we’re sending an Uber to come help you to the bank.'”
Hardaway said he was out of town when all this happened, and that thankfully his mom eventually grew exasperated and gave up trying to help the scammers.
“They told her they were sending an Uber to pick her up and that it was on its way,” Hardaway said. “I don’t know if the Uber ever got there. But my mom went over to the neighbor’s house and they saw it for what it was — a scam.”
Hardaway said he has since wiped her computer, reinstalled the operating system and changed her passwords. But he says the incident has left his mom rattled.
“She’s really second-guessing herself now,” Hardaway said. “She’s not computer-savvy, and just moved down here from Boston during COVID to be near us, but she’s living by herself and feeling isolated and vulnerable, and stuff like this doesn’t help.”
According to the Federal Bureau of Investigation (FBI), seniors are often targeted because they tend to be trusting and polite. More importantly, they also usually have financial savings, own a home, and have good credit—all of which make them attractive to scammers.
“Additionally, seniors may be less inclined to report fraud because they don’t know how, or they may be too ashamed of having been scammed,” the FBI warned in May. “They might also be concerned that their relatives will lose confidence in their abilities to manage their own financial affairs. And when an elderly victim does report a crime, they may be unable to supply detailed information to investigators.”
In 2021, more than 92,000 victims over the age of 60 reported losses of $1.7 billion to the FBI’s Internet Crime Complaint Center (IC3). The FBI says that represents a 74 percent increase in losses over losses reported in 2020.
The abuse of ride-sharing services to scam the elderly is not exactly new. Authorities in Tampa, Fla. say they’re investigating an incident from December 2021 where fraudsters who’d stolen $700,000 from elderly grandparents used Uber rides to pick up bundles of cash from their victims.
Earlier this month, the administrator of the cybercrime forum Breached received a cease-and-desist letter from a cybersecurity firm. The missive alleged that an auction on the site for data stolen from 10 million customers of Mexico’s second-largest bank was fake news and harming the bank’s reputation. The administrator responded to this empty threat by purchasing the stolen banking data and leaking it on the forum for everyone to download.
On August 3, 2022, someone using the alias “Holistic-K1ller” posted on Breached a thread selling data allegedly stolen from Grupo Financiero Banorte, Mexico’s second-biggest financial institution by total loans. Holistic-K1ller said the database included the full names, addresses, phone numbers, Mexican tax IDs (RFC), email addresses and balances on more than 10 million citizens.
There was no reason to believe Holistic-K1ller had fabricated their breach claim. This identity has been highly active on Breached and its predecessor RaidForums for more than two years, mostly selling databases from hacked Mexican entities. Last month, they sold customer information on 36 million customers of the Mexican phone company Telcel; in March, they sold 33,000 images of Mexican IDs — with the front picture and a selfie of each citizen. That same month, they also sold data on 1.4 million customers of Mexican lending platform Yotepresto.
But this history was either overlooked or ignored by Group-IB, the Singapore-based cybersecurity firm apparently hired by Banorte to help respond to the data breach.
“The Group-IB team has discovered a resource containing a fraudulent post offering to buy Grupo Financiero Banorte’s leaked databases,” reads a letter the Breach administrator said they received from Group-IB. “We ask you to remove this post containing Banorte data. Thank you for your cooperation and prompt attention to this urgent matter.”
The administrator of Breached is “Pompompurin,” the same individual who alerted this author in November 2021 to a glaring security hole in a U.S. Justice Department website that was used to spoof security alerts from the FBI. In a post to Breached on Aug. 8, Pompompurin said they bought the Banorte database from Holistic-K1ller’s sales thread because Group-IB was sending emails complaining about it.
“They also attempted to submit DMCA’s against the website,” Pompompurin wrote, referring to legal takedown requests under the Digital Millennium Copyright Act. “Make sure to tell Banorte that now they need to worry about the data being leaked instead of just being sold.”
Group-IB CEO Dmitriy Volkov said the company has seen some success in the past asking hackers to remove or take down certain information, but that making such requests is not a typical response for the security firm.
“It is not a common practice to send takedown notifications to such forums demanding that such content be removed,” Volkov said. “But these abuse letters are legally binding, which helps build a foundation for further steps taken by law enforcement agencies. Actions contrary to international rules in the regulated space of the Internet only lead to more severe crimes, which — as we know from the case of Raidforums — are successfully investigated and stopped by law enforcement.”
Banorte did not respond to requests for comment. But in a brief written statement picked up on Twitter, Banorte said there was no breach involving their infrastructure, and the data being sold is old.
“There has been no violation of our platforms and technological infrastructure,” Banorte said. “The set of information referred to is inaccurate and outdated, and does not put our users and customers at risk.”
That statement may be 100 percent true. Still, it is difficult to think of a better example of how not to do breach response. Banorte shrugging off this incident as a nothingburger is baffling: While it is almost certainly true that the bank balance information in the Banorte leak is now out of date, the rest of the information (tax IDs, phone numbers, email addresses) is harder to change.
“Is there one person from our community that think sending cease and desist letter to a hackers forum operator is a good idea?,” asked Ohad Zaidenberg, founder of CTI League, a volunteer emergency response community that emerged in 2020 to help fight COVID-19 related scams. “Who does it? Instead of helping, they pushed the organization from the hill.”
Kurt Seifried, director of IT for the CloudSecurityAlliance, was similarly perplexed by the response to the Banorte breach.
“If the data wasn’t real….did the bank think a cease and desist would result in the listing being removed?” Seifried wondered on Twitter. “I mean, isn’t selling breach data a worse crime usually than slander or libel? What was their thought process?”
A more typical response when a large bank suspects a breach is to approach the seller privately through an intermediary to ascertain if the information is valid and what it might cost to take it off the market. While it may seem odd to expect cybercriminals to make good on their claims to sell stolen data to only one party, removing sold stolen items from inventory is a fairly basic function of virtually all cybercriminal markets today (apart from perhaps sites that traffic in stolen identity data).
At a minimum, negotiating or simply engaging with a data seller can buy the victim organization additional time and clues with which to investigate the claim and ideally notify affected parties of a breach before the stolen data winds up online.
It is true that a large number of hacked databases put up for sale on the cybercrime underground are sold only after a small subset of in-the-know thieves have harvested all of the low-hanging fruit in the data — e.g., access to cryptocurrency accounts or user credentials that are recycled across multiple websites. And it’s certainly not unheard of for cybercriminals to go back on their word and re-sell or leak information that they have sold previously.
But companies in the throes of responding to a data security incident do themselves and customers no favors when they underestimate their adversaries, or try to intimidate cybercrooks with legal threats. Such responses generally accomplish nothing, except unnecessarily upping the stakes for everyone involved while displaying a dangerous naiveté about how the cybercrime underground works.
Update, Aug. 17, 10:32 a.m.: Thanks to a typo by this author, a request for comment sent to Group-IB was not delivered in advance of this story. The copy above has been updated to include a comment from Group-IB’s CEO.
Scammers are using invoices sent through PayPal.com to trick recipients into calling a number to dispute a pending charge. The missives — which come from Paypal.com and include a link at Paypal.com that displays an invoice for the supposed transaction — state that the user’s account is about to be charged hundreds of dollars. Recipients who call the supplied toll-free number to contest the transaction are soon asked to download software that lets the scammers assume remote control over their computer.
KrebsOnSecurity recently heard from a reader who received an email from paypal.com that he immediately suspected was phony. The message’s subject read, “Billing Department of PayPal updated your invoice.”
A copy of the phishing message included in the PayPal.com invoice.
While the phishing message attached to the invoice is somewhat awkwardly worded, there are many convincing aspects of this hybrid scam. For starters, all of the links in the email lead to paypal.com. Hovering over the “View and Pay Invoice” button shows the button indeed wants to load a link at paypal.com, and clicking that link indeed brings up an active invoice at paypal.com.
Also, the email headers in the phishing message (PDF) show that it passed all email validation checks as being sent by PayPal, and that it was sent through an Internet address assigned to PayPal.
Both the email and the invoice state that “there is evidence that your PayPal account has been accessed unlawfully.” The message continues:
“$600.00 has been debited to your account for the Walmart Gift Card purchase. This transaction will appear in the automatically deducted amount on PayPal activity after 24 hours. If you suspect you did not make this transaction, immediately contact us at the toll-free number….”
Here’s the invoice that popped up when the “View and Pay Invoice” button was clicked:
The phony PayPal invoice, which was sent and hosted by PayPal.com.
The reader who shared this phishing email said he logged into his PayPal account and could find no signs of the invoice in question. A call to the toll-free number listed in the invoice was received by a man who answered the phone as generic “customer service,” instead of trying to spoof PayPal or Walmart. Very quickly into the conversation he suggested visiting a site called globalquicksupport[.]com to download a remote administration tool. It was clear then where the rest of this call was going.
I can see this scam tricking a great many people, especially since both the email and invoice are sent through PayPal’s systems — which practically guarantees that the message will be successfully delivered. The invoices appear to have been sent from a compromised or fraudulent PayPal Business account, which allows users to send invoices like the one shown above. Details of this scam were shared Wednesday with PayPal’s anti-abuse (phishing@paypal.com) and media relations teams.
PayPal said in a written statement that phishing attempts are common and can take many forms.
“We have a zero-tolerance policy on our platform for attempted fraudulent activity, and our teams work tirelessly to protect our customers,” PayPal said. “We are aware of this well-known phishing scam and have put additional controls in place to mitigate this specific incident. Nonetheless, we encourage customers to always be vigilant online and to contact Customer Service directly if they suspect they are a target of a scam.”
It’s remarkable how well today’s fraudsters have adapted to hijacking the very same tools that financial institutions have long used to make their customers feel safe transacting online. It’s no accident that one of the most prolific scams going right now — the Zelle Fraud Scam — starts with a text message about an unauthorized payment that appears to come from your bank. After all, financial institutions have spent years encouraging customers to sign up for mobile alerts via SMS about suspicious transactions, and to expect the occasional inbound call about possibly fraudulent transactions.
Also, today’s scammers are less interested in stealing your PayPal login than they are in phishing your entire computer and online life with remote administration software, which seems to be the whole point of so many scams these days. Because why rob just one online account when you can plunder them all?
The best advice to sidestep phishing scams is to avoid clicking on links that arrive unbidden in emails, text messages and other mediums. Most phishing scams invoke a temporal element that warns of dire consequences should you fail to respond or act quickly. If you’re unsure whether the message is legitimate, take a deep breath and visit the site or service in question manually — ideally, using a browser bookmark to avoid potential typosquatting sites.
Phishers are enjoying remarkable success using text messages to steal remote access credentials and one-time passcodes from employees at some of the world’s largest technology companies and customer support firms. A recent spate of SMS phishing attacks from one cybercriminal group has spawned a flurry of breach disclosures from affected companies, which are all struggling to combat the same lingering security threat: The ability of scammers to interact directly with employees through their mobile devices.
In mid-June 2022, a flood of SMS phishing messages began targeting employees at commercial staffing firms that provide customer support and outsourcing to thousands of companies. 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.
The phishers behind this scheme used newly-registered domains that often included the name of the target 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 leveraged a 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. But because of the way the bot was configured, it was possible for security researchers to capture the information being sent by victims to the public Telegram server.
This data trove was first reported by security researchers at Singapore-based Group-IB, which dubbed the campaign “0ktapus” for the attackers targeting organizations using identity management tools from Okta.com.
“This case is of interest because despite using low-skill methods it was able to compromise a large number of well-known organizations,” Group-IB wrote. “Furthermore, once the attackers compromised an organization they were quickly able to pivot and launch subsequent supply chain attacks, indicating that the attack was planned carefully in advance.”
It’s not clear how many of these phishing text messages were sent out, but the Telegram bot data reviewed by KrebsOnSecurity shows they generated nearly 10,000 replies over approximately two months of sporadic SMS phishing attacks targeting more than a hundred companies.
A great many responses came from those who were apparently wise to the scheme, as evidenced by the hundreds of hostile replies that included profanity or insults aimed at the phishers: The very first reply recorded in the Telegram bot data came from one such employee, who responded with the username “havefuninjail.”
Still, thousands replied with what appear to be legitimate credentials — many of them including one-time codes needed for multi-factor authentication. On July 20, the attackers turned their sights on internet infrastructure giant Cloudflare.com, and the intercepted credentials show at least three employees fell for the scam.

In a blog post earlier this month, Cloudflare said it detected the account takeovers and that no Cloudflare systems were compromised. Cloudflare said it does not rely on one-time passcodes as a second factor, so there was nothing to provide to the attackers. But Cloudflare said it wanted to call attention to the phishing attacks because they would probably work against most other companies.
“This was a sophisticated attack targeting employees and systems in such a way that we believe most organizations would be likely to be breached,” Cloudflare CEO Matthew Prince wrote. “On July 20, 2022, the Cloudflare Security team received reports of employees receiving legitimate-looking text messages pointing to what appeared to be a Cloudflare Okta login page. The messages began at 2022-07-20 22:50 UTC. Over the course of less than 1 minute, at least 76 employees received text messages on their personal and work phones. Some messages were also sent to the employees family members.”
On three separate occasions, the phishers targeted employees at Twilio.com, a San Francisco based company that provides services for making and receiving text messages and phone calls. It’s unclear how many Twilio employees received the SMS phishes, but the data suggest at least four Twilio employees responded to a spate of SMS phishing attempts on July 27, Aug. 2, and Aug. 7.
On that last date, Twilio disclosed that on Aug. 4 it became aware of unauthorized access to information related to a limited number of Twilio customer accounts through a sophisticated social engineering attack designed to steal employee credentials.
“This broad based attack against our employee base succeeded in fooling some employees into providing their credentials,” Twilio said. “The attackers then used the stolen credentials to gain access to some of our internal systems, where they were able to access certain customer data.”
That “certain customer data” included information on roughly 1,900 users of the secure messaging app Signal, which relied on Twilio to provide phone number verification services. In its disclosure on the incident, Signal said that with their access to Twilio’s internal tools the attackers were able to re-register those users’ phone numbers to another device.
On Aug. 25, food delivery service DoorDash disclosed that a “sophisticated phishing attack” on a third-party vendor allowed attackers to gain access to some of DoorDash’s internal company tools. DoorDash said intruders stole information on a “small percentage” of users that have since been notified. TechCrunch reported last week that the incident was linked to the same phishing campaign that targeted Twilio.
This phishing gang apparently had great success targeting employees of all the major mobile wireless providers, but most especially T-Mobile. Between July 10 and July 16, dozens of T-Mobile employees fell for the phishing messages and provided their remote access credentials.
“Credential theft continues to be an ongoing issue in our industry as wireless providers are constantly battling bad actors that are focused on finding new ways to pursue illegal activities like this,” T-Mobile said in a statement. “Our tools and teams worked as designed to quickly identify and respond to this large-scale smishing attack earlier this year that targeted many companies. We continue to work to prevent these types of attacks and will continue to evolve and improve our approach.”
This same group saw hundreds of responses from employees at some of the largest customer support and staffing firms, including Teleperformanceusa.com, Sitel.com and Sykes.com. Teleperformance did not respond to requests for comment. KrebsOnSecurity did hear from Christopher Knauer, global chief security officer at Sitel Group, the customer support giant that recently acquired Sykes. Knauer said the attacks leveraged newly-registered domains and asked employees to approve upcoming changes to their work schedules.
Image: Group-IB.
Knauer said the attackers set up the phishing domains just minutes in advance of spamming links to those domains in phony SMS alerts to targeted employees. He said such tactics largely sidestep automated alerts generated by companies that monitor brand names for signs of new phishing domains being registered.
“They were using the domains as soon as they became available,” Knauer said. “The alerting services don’t often let you know until 24 hours after a domain has been registered.”
On July 28 and again on Aug. 7, several employees at email delivery firm Mailchimp provided their remote access credentials to this phishing group. According to an Aug. 12 blog post, the attackers used their access to Mailchimp employee accounts to steal data from 214 customers involved in cryptocurrency and finance.
On Aug. 15, the hosting company DigitalOcean published a blog post saying it had severed ties with MailChimp after its Mailchimp account was compromised. DigitalOcean said the MailChimp incident resulted in a “very small number” of DigitalOcean customers experiencing attempted compromises of their accounts through password resets.
According to interviews with multiple companies hit by the group, the attackers are mostly interested in stealing access to cryptocurrency, and to companies that manage communications with people interested in cryptocurrency investing. In an Aug. 3 blog post from email and SMS marketing firm Klaviyo.com, the company’s CEO recounted how the phishers gained access to the company’s internal tools, and used that to download information on 38 crypto-related accounts.

The ubiquity of mobile phones became a lifeline for many companies trying to manage their remote employees throughout the Coronavirus pandemic. But these same mobile devices are fast becoming a liability for organizations that use them for phishable forms of multi-factor authentication, such as one-time codes generated by a mobile app or delivered via SMS.
Because as we can see from the success of this phishing group, this type of data extraction is now being massively automated, and employee authentication compromises can quickly lead to security and privacy risks for the employer’s partners or for anyone in their supply chain.
Unfortunately, a great many companies still rely on SMS for employee multi-factor authentication. According to a report this year from Okta, 47 percent of workforce customers deploy SMS and voice factors for multi-factor authentication. That’s down from 53 percent that did so in 2018, Okta found.
Some companies (like Knauer’s Sitel) have taken to requiring that all remote access to internal networks be managed through work-issued laptops and/or mobile devices, which are loaded with custom profiles that can’t be accessed through other devices.
Others are moving away from SMS and one-time code apps and toward requiring employees to use physical FIDO multi-factor authentication devices such as security keys, which can neutralize phishing attacks because any stolen credentials can’t be used unless the phishers also have physical access to the user’s security key or mobile device.
This came in handy for Twitter, which announced last year that it was moving all of its employees to using security keys, and/or biometric authentication via their mobile device. The phishers’ Telegram bot reported that on June 16, 2022, five employees at Twitter gave away their work credentials. In response to questions from KrebsOnSecurity, Twitter confirmed several employees were relieved of their employee usernames and passwords, but that its security key requirement prevented the phishers from abusing that information.
Twitter accelerated its plans to improve employee authentication following the July 2020 security incident, wherein several employees were phished and relieved of credentials for Twitter’s internal tools. In that intrusion, the attackers used Twitter’s tools to hijack accounts for some of the world’s most recognizable public figures, executives and celebrities — forcing those accounts to tweet out links to bitcoin scams.
“Security keys can differentiate legitimate sites from malicious ones and block phishing attempts that SMS 2FA or one-time password (OTP) verification codes would not,” Twitter said in an Oct. 2021 post about the change. “To deploy security keys internally at Twitter, we migrated from a variety of phishable 2FA methods to using security keys as our only supported 2FA method on internal systems.”
Update, 6:02 p.m. ET: Clarified that Cloudflare does not rely on TOTP (one-time multi-factor authentication codes) as a second factor for employee authentication.
A 21-year-old New Jersey man has been arrested and charged with stalking in connection with a federal investigation into groups of cybercriminals who are settling scores by hiring people to carry out physical attacks on their rivals. Prosecutors say the defendant recently participated in several of these schemes — including firing a handgun into a Pennsylvania home and torching a residence in another part of the state with a Molotov Cocktail.
Patrick McGovern-Allen of Egg Harbor Township, N.J. was arrested on Aug. 12 on a warrant from the U.S. Federal Bureau of Investigation. An FBI complaint alleges McGovern-Allen was part of a group of co-conspirators who are at the forefront of a dangerous escalation in coercion and intimidation tactics increasingly used by competing cybercriminal groups.
Prosecutors say that around 2 a.m. on Jan 2, 2022, McGovern-Allen and an unidentified co-conspirator fired multiple handgun rounds into a residence in West Chester, Pa. Fortunately, none of the residents inside the home at the time were injured. But prosecutors say the assailants actually recorded video of the attack as “proof” that the shooting had been carried out.
A copy of that video was obtained by KrebsOnSecurity. According to investigators, McGovern-Allen was one of the shooters, who yelled “Justin Active was here” as they haphazardly fired at least eight rounds into the lower story of the West Chester residence.
On Dec. 18, 2021, police in Abington Township, Pa., responded to reports of a house fire from homeowners who said it sounded like something was thrown at their residence just prior to the fire.
Weeks later, on the day of the shooting in West Chester, a detective with the Westtown East Goshen Police Department contacted the Abington police and shared another video that was circulating on several online message boards that appeared to show two individuals setting fire to the Abington Township residence. The criminal complaint said the two police officers agreed the same suspect was present in both videos.
A copy of that video also was obtained by KrebsOnSecurity, and it shows at least two individuals smashing a window, then lighting a rag-soaked Mad Dog 20/20 grape wine bottle and hurling it at the side of the home [Update: My apologies for the file download link, but YouTube just deleted both of the videos included in this story — for allegedly violating their community standards].
“The Molotov cocktail caused the immediate surrounding area to ignite, including the siding of the house, grass, and the wooden chair,” the government’s complaint against McGovern-Allen states. “The two suspects then fled on foot toward the street and begin yelling something when the video stops.”
The government mentions the victims only by their initials — “K.M.” in the shooting and “A.R.” in the firebombing — but said both had been the target of previous harassment by rival cybercriminal groups that included swatting attacks, wherein the perpetrators spoof a distress call to the police about a hostage situation, suicide or bomb threat with the goal of sending a heavily-armed police response to a targeted address.
A number of previous swatting incidents have turned deadly. But these more “hands-on” and first person attacks are becoming increasingly common within certain cybercriminal communities, particularly those engaged in SIM swapping, a crime in which identity thieves hijack a target’s mobile phone number and use that to wrest control over the victim’s various online accounts and identities.
The complaint mentions a handle and user ID allegedly used by McGovern-Allen’s online persona “Tongue” on the Discord chat service, (user: “Tongue#0001”).
“In the chats, [Tongue] tells other Discord users that he was the person who shot K.M.’s house and that he was willing to commit firebombings using Molotov Cocktails,” the complaint alleges. “For example, in one Discord chat from March 2022, [the defendant] states ‘if you need anything done for $ lmk [“let me know”]/I did a shooting/Molotov/but I can also do things for ur entertainment.”
KrebsOnsecurity reviewed hundreds of chat records tied to this Tongue alias, and it appears both attacks were motivated by a desire to get back at a rival cybercriminal by attacking the female friends of that rival.
Recall that the shooters in the West Chester, Pa. incident shouted “Justin Active was here.” Justin Active is the nickname of an individual who is just as active in the same cybercriminal channels, but who has vehemently denied knowledge of or participation in the shooting. Justin Active said on Telegram that the person targeted in the shooting was his ex-girlfriend, and that the firebombing targeted another friend of his.
Justin Active has claimed for months that McGovern-Allen was responsible for both attacks, saying they were intended as an intimidation tactic against him. “DO THE PATRICK MCGOVERN ALLEN RAID DANCE!,” Justin Active’s alias “Nutcase68” shouted on Telegram on Aug. 12, the same day McGovern-Allen was arrested by authorities.
Justin Active’s version of events seems to be supported by a reference in the criminal complaint to an April 2, 2022 chat in which Tongue explained the reason for the shooting.
“The video/is [K]’s house/getting shit/shot/justin active/ was her current bf/ the reason it happened,” Tongue explained. “So that’s why Justin active was there.”
The Telegram chat channels that Justin Active and Tongue both frequented have hundreds to thousands of members each, and some of the more interesting solicitations on these communities are job offers for in-person assignments and tasks that can be found if one searches for posts titled, “If you live near,” or “IRL job” — short for “in real life” job.
A number of these classified ads are in service of performing “brickings,” where someone is hired to visit a specific address and toss a brick through the target’s window.
“If you live near Edmonton Canada dm me need someone bricked,” reads on Telegram message on May 31, 2022.
“If you live near [address redacted] Lakewood, CA, dm [redacted] Paying 3k to slash the tires,” reads another help wanted ad in the same channel on Feb. 24, 2022. “If you live near here and can brick them, dm [address omitted] Richland, WA,” reads another from that same day.
McGovern-Allen was in the news not long ago. According to a Sept. 2020 story from The Press of Atlantic City, a then 19-year-old Patrick McGovern Allen was injured after driving into a building and forcing residents from their home.
“Police found a 2007 Lexus, driven by Patrick McGovern-Allen, 19, that had lost control and left the road, crashing into the eastern end of the 1600 building,” the story recounted. “The car was driven through the steps that provide access to the second-floor apartments, destroying them, and also caused damage to the outer wall.”
A search on the Inmate Locator of the U.S. Bureau of Prisons website shows that McGovern-Allen remains in federal custody at a detention facility in Philadelphia. He’s currently represented by a public defender who has not responded to requests for comment.
A copy of the criminal complaint against McGovern-Allen is available here (PDF).
Many of the individuals involved in paying others to commit these physical attacks are also frequent participants in several Telegram channels focused singularly on SIM swapping activity. As a result, the vast majority of the people being targeted for brickings and other real-life physical assaults tend to be other cybercriminals involved in SIM swapping crimes (or individuals on the periphery of that scene).
There are dozens of SIM swappers who are now teenage or 20-something millionaires, by virtue of having stolen vast sums of cryptocurrencies from SIM swapping victims. And now many of these same individuals are finding that communities like Telegram can be leveraged to hire physical harassment and intimidation of their rivals and competitors.
The primary barrier to hiring someone to brick a home or slash some tires seems to be the costs involved: A number of solicitations for these services advertised payment of $3,000 or more upon proof of successful completion, which usually involves recording the attack and hiring a getaway driver in the town where the crime is to take place (calling a cab or hailing an Uber from the scene of a bricking isn’t the brightest idea).
My fear is these violence-as-a-service offerings will at some point migrate outside of the SIM swapping communities. This is precisely what happened with swatting, which for years was a crime perpetrated almost exclusively against online gamers and people streaming their games online. These days, swatting attacks are commonly used by SIM swapping groups as a way to harass and extort regular Internet users into giving up prized social media account names that can be resold for thousands of dollars.
Someone has recently created a large number of fake LinkedIn profiles for Chief Information Security Officer (CISO) roles at some of the world’s largest corporations. It’s not clear who’s behind this network of fake CISOs or what their intentions may be. But the fabricated LinkedIn identities are confusing search engine results for CISO roles at major companies, and they are being indexed as gospel by various downstream data-scraping sources.
If one searches LinkedIn for the CISO of the energy giant Chevron, one might find the profile for a Victor Sites, who says he’s from Westerville, Ohio and is a graduate of Texas A&M University.
The LinkedIn profile for Victor Sites, who is most certainly NOT the CISO of Chevron.
Of course, Sites is not the real CISO of Chevron. That role is currently occupied by Christopher Lukas of Danville, Calif. If you were confused at this point, you might ask Google who it thinks is the current Chief Information Security Officer of Chevron. When KrebsOnSecurity did that earlier this morning, the fake CISO profile was the very first search result returned (followed by the LinkedIn profile for the real Chevron CISO).
Helpfully, LinkedIn seems to be able to detect something in common about all these fake CISO profiles, because it suggested I view a number of them in the “People Also Viewed” column seen in the image above. There are two fake CISO profiles suggested there, including one for a Maryann Robles, who claims to be the CISO of another energy giant — ExxonMobil.
Maryann’s profile says she’s from Tupelo, Miss., and includes this detail about how she became a self-described “old-school geek.”
“Since playing Tradewars on my Tandy 1000 with a 300 baud modem in the early ’90s, I’ve had a lifelong passion for technology, which I’ve carried with me as Deputy CISO of the world’s largest health plan,” her profile reads.
However, this description appears to have been lifted from the profile for the real CISO at the Centers for Medicare & Medicaid Services in Baltimore, Md.
Interestingly, Maryann’s LinkedIn profile was accepted as truth by Cybercrime Magazine’s CISO 500 listing, which claims to maintain a list of the current CISOs at America’s largest companies:
The fake CISO for ExxOnMobil was indexed in Cybercrime Magazine’s CISO 500.
Rich Mason, the former CISO at Fortune 500 firm Honeywell, began warning his colleagues on LinkedIn about the phony profiles earlier this week.
“It’s interesting the downstream sources that repeat LinkedIn bogus content as truth,” Mason said. “This is dangerous, Apollo.io, Signalhire, and Cybersecurity Ventures.”
Google wasn’t fooled by the phony LinkedIn profile for Jennie Biller, who claims to be CISO at biotechnology giant Biogen (the real Biogen CISO is Russell Koste). But Biller’s profile is worth mentioning because it shows how some of these phony profiles appear to be quite hastily assembled. Case in point: Biller’s name and profile photo suggest she is female, however the “About” description of her accomplishments uses male pronouns. Also, it might help that Jennie only has 18 connections on LinkedIn.
Again, we don’t know much about who or what is behind these profiles, but in August the security firm Mandiant (recently acquired by Google) told Bloomberg that hackers working for the North Korean government have been copying resumes and profiles from leading job listing platforms LinkedIn and Indeed, as part of an elaborate scheme to land jobs at cryptocurrency firms.
None of the profiles listed here responded to requests for comment (or to become a connection).
In a statement provided to KrebsOnSecurity, LinkedIn said its teams were actively working to take these fake accounts down.
“We do have strong human and automated systems in place, and we’re continually improving, as fake account activity becomes more sophisticated,” the statement reads. “In our transparency report we share how our teams plus automated systems are stopping the vast majority of fraudulent activity we detect in our community – around 96% of fake accounts and around 99.1% of spam and scam.”
LinkedIn could take one simple step that would make it far easier for people to make informed decisions about whether to trust a given profile: Add a “created on” date for every profile. Twitter does this, and it’s enormously helpful for filtering out a great deal of noise and unwanted communications.
The former CISO Mason said LinkedIn also could experiment with offering something akin to Twitter’s verified mark to users who chose to validate that they can respond to email at the domain associated with their stated current employer.
“If I saw that a LinkedIn profile had been domain-validated, then my confidence in that profile would go way up,” Mason said, noting that many of the fake profiles had hundreds of followers, including dozens of real CISOs. Maryann’s profile grew by a hundred connections in just the past few days, he said.
“If we have CISOs that are falling for this, what hopes do the masses have?” Mason said.
Mason said LinkedIn also needs a more streamlined process for allowing employers to remove phony employee accounts. He recently tried to get a phony profile removed from LinkedIn for someone who falsely claimed to have worked for his company.
“I shot a note to LinkedIn and said please remove this, and they said, well, we have to contact that person and arbitrate this,” he said. “They gave the guy two weeks and he didn’t respond, so they took it down. But that doesn’t scale, and there needs to be a mechanism where an employer can contact LinkedIn and have these fake profiles taken down in less than two weeks.”
A recent proliferation of phony executive profiles on LinkedIn is creating something of an identity crisis for the business networking site, and for companies that rely on it to hire and screen prospective employees. The fabricated LinkedIn identities — which pair AI-generated profile photos with text lifted from legitimate accounts — are creating major headaches for corporate HR departments and for those managing invite-only LinkedIn groups.
Some of the fake profiles flagged by the co-administrator of a popular sustainability group on LinkedIn.
Last week, KrebsOnSecurity examined a flood of inauthentic LinkedIn profiles all claiming Chief Information Security Officer (CISO) roles at various Fortune 500 companies, including Biogen, Chevron, ExxonMobil, and Hewlett Packard.
Since then, the response from LinkedIn users and readers has made clear that these phony profiles are showing up en masse for virtually all executive roles — but particularly for jobs and industries that are adjacent to recent global events and news trends.
Hamish Taylor runs the Sustainability Professionals group on LinkedIn, which has more than 300,000 members. Together with the group’s co-owner, Taylor said they’ve blocked more than 12,700 suspected fake profiles so far this year, including dozens of recent accounts that Taylor describes as “cynical attempts to exploit Humanitarian Relief and Crisis Relief experts.”
“We receive over 500 fake profile requests to join on a weekly basis,” Taylor said. “It’s hit like hell since about January of this year. Prior to that we did not get the swarms of fakes that we now experience.”
The opening slide for a plea by Taylor’s group to LinkedIn.
Taylor recently posted an entry on LinkedIn titled, “The Fake ID Crisis on LinkedIn,” which lampooned the “60 Least Wanted ‘Crisis Relief Experts’ — fake profiles that claimed to be experts in disaster recovery efforts in the wake of recent hurricanes. The images above and below show just one such swarm of profiles the group flagged as inauthentic. Virtually all of these profiles were removed from LinkedIn after KrebsOnSecurity tweeted about them last week.
Another “swarm” of LinkedIn bot accounts flagged by Taylor’s group.
Mark Miller is the owner of the DevOps group on LinkedIn, and says he deals with fake profiles on a daily basis — often hundreds per day. What Taylor called “swarms” of fake accounts Miller described instead as “waves” of incoming requests from phony accounts.
“When a bot tries to infiltrate the group, it does so in waves,” Miller said. “We’ll see 20-30 requests come in with the same type of information in the profiles.”
After screenshotting the waves of suspected fake profile requests, Miller started sending the images to LinkedIn’s abuse teams, which told him they would review his request but that he may never be notified of any action taken.
Some of the bot profiles identified by Mark Miller that were seeking access to his DevOps LinkedIn group. Miller said these profiles are all listed in the order they appeared.
Miller said that after months of complaining and sharing fake profile information with LinkedIn, the social media network appeared to do something which caused the volume of group membership requests from phony accounts to drop precipitously.
“I wrote our LinkedIn rep and said we were considering closing the group down the bots were so bad,” Miller said. “I said, ‘You guys should be doing something on the backend to block this.”
Jason Lathrop is vice president of technology and operations at ISOutsource, a Seattle-based consulting firm with roughly 100 employees. Like Miller, Lathrop’s experience in fighting bot profiles on LinkedIn suggests the social networking giant will eventually respond to complaints about inauthentic accounts. That is, if affected users complain loudly enough (posting about it publicly on LinkedIn seems to help).
Lathrop said that about two months ago his employer noticed waves of new followers, and identified more than 3,000 followers that all shared various elements, such as profile photos or text descriptions.
“Then I noticed that they all claim to work for us at some random title within the organization,” Lathrop said in an interview with KrebsOnSecurity. “When we complained to LinkedIn, they’d tell us these profiles didn’t violate their community guidelines. But like heck they don’t! These people don’t exist, and they’re claiming they work for us!”
Lathrop said that after his company’s third complaint, a LinkedIn representative responded by asking ISOutsource to send a spreadsheet listing every legitimate employee in the company, and their corresponding profile links.
Not long after that, the phony profiles that were not on the company’s list were deleted from LinkedIn. Lathrop said he’s still not sure how they’re going to handle getting new employees allowed into their company on LinkedIn going forward.
It remains unclear why LinkedIn has been flooded with so many fake profiles lately, or how the phony profile photos are sourced. Random testing of the profile photos shows they resemble but do not match other photos posted online. Several readers pointed out one likely source — the website thispersondoesnotexist.com, which makes using artificial intelligence to create unique headshots a point-and-click exercise.
Cybersecurity firm Mandiant (recently acquired by Google) told Bloomberg that hackers working for the North Korean government have been copying resumes and profiles from leading job listing platforms LinkedIn and Indeed, as part of an elaborate scheme to land jobs at cryptocurrency firms.
Fake profiles also may be tied to so-called “pig butchering” scams, wherein people are lured by flirtatious strangers online into investing in cryptocurrency trading platforms that eventually seize any funds when victims try to cash out.
In addition, identity thieves have been known to masquerade on LinkedIn as job recruiters, collecting personal and financial information from people who fall for employment scams.
But the Sustainability Group administrator Taylor said the bots he’s tracked strangely don’t respond to messages, nor do they appear to try to post content.
“Clearly they are not monitored,” Taylor assessed. “Or they’re just created and then left to fester.”
This experience was shared by the DevOp group admin Miller, who said he’s also tried baiting the phony profiles with messages referencing their fakeness. Miller says he’s worried someone is creating a massive social network of bots for some future attack in which the automated accounts may be used to amplify false information online, or at least muddle the truth.
“It’s almost like someone is setting up a huge bot network so that when there’s a big message that needs to go out they can just mass post with all these fake profiles,” Miller said.
In last week’s story on this topic, I suggested LinkedIn could take one simple step that would make it far easier for people to make informed decisions about whether to trust a given profile: Add a “created on” date for every profile. Twitter does this, and it’s enormously helpful for filtering out a great deal of noise and unwanted communications.
Many of our readers on Twitter said LinkedIn needs to give employers more tools — perhaps some kind of application programming interface (API) — that would allow them to quickly remove profiles that falsely claim to be employed at their organizations.
Another reader suggested LinkedIn also could experiment with offering something akin to Twitter’s verified mark to users who chose to validate that they can respond to email at the domain associated with their stated current employer.
In response to questions from KrebsOnSecurity, LinkedIn said it was considering the domain verification idea.
“This is an ongoing challenge and we’re constantly improving our systems to stop fakes before they come online,” LinkedIn said in a written statement. “We do stop the vast majority of fraudulent activity we detect in our community – around 96% of fake accounts and around 99.1% of spam and scams. We’re also exploring new ways to protect our members such as expanding email domain verification. Our community is all about authentic people having meaningful conversations and to always increase the legitimacy and quality of our community.”
In a story published Wednesday, Bloomberg noted that LinkedIn has largely so far avoided the scandals about bots that have plagued networks like Facebook and Twitter. But that shine is starting to come off, as more users are forced to waste more of their time fighting off inauthentic accounts.
“What’s clear is that LinkedIn’s cachet as being the social network for serious professionals makes it the perfect platform for lulling members into a false sense of security,” Bloomberg’s Tim Cuplan wrote. “Exacerbating the security risk is the vast amount of data that LinkedIn collates and publishes, and which underpins its whole business model but which lacks any robust verification mechanisms.”
AMLBot, a service that helps businesses avoid transacting with cryptocurrency wallets that have been sanctioned for cybercrime activity, said an investigation published by KrebsOnSecurity last year helped it shut down three dark web services that secretly resold its technology to help cybercrooks avoid detection by anti-money laundering systems.
Antinalysis, as it existed in 2021.
In August 2021, KrebsOnSecurity published “New Anti Anti-Money Laundering Services for Crooks,” which examined Antinalysis, a service marketed on cybercrime forums that purported to offer a glimpse of how one’s payment activity might be flagged by law enforcement agencies and private companies that track and trace cryptocurrency transactions.
“Worried about dirty funds in your BTC address? Come check out Antinalysis, the new address risk analyzer,” read the service’s opening announcement. “This service is dedicated to individuals that have the need to possess complete privacy on the blockchain, offering a perspective from the opponent’s point of view in order for the user to comprehend the possibility of his/her funds getting flagged down under autocratic illegal charges.”
Antinalysis allows free lookups, but anyone wishing to conduct bulk look-ups has to pay at least USD $3, with a minimum $30 purchase. Other plans go for as high as $6,000 for 5,000 requests. Nick Bax, a security researcher who specializes in tracing cryptocurrency transactions, told KrebsOnSecurity at the time that Antinalysis was likely a clone of AMLBot because the two services generated near-identical results.
AMLBot shut down Antinalysis’s access just hours after last year’s story went live. However, Antinalysis[.]org remains online and accepting requests, as does the service’s Tor-based domain, and it is unclear how those services are sourcing their information.
AMLBot spokesperson Polina Smoliar said the company undertook a thorough review after that discovery, and in the process found two other services similar to Antinalysis that were reselling their application programming interface (API) access to cybercrooks.
Smoliar said that following the revelations about Antinalysis, AMLBot audited its entire client base, and implemented the ability to provide APIs only after a contract is signed and the client has been fully audited. AMLBot said it also instituted 24/7 monitoring of all client transactions.
“As a result of these actions, two more services with the name AML (the same as AMLBot has) were found to be involved in fraudulent schemes,” Smoliar said. “Information about the fraudsters was also sent to key market participants, and their transaction data was added to the tracking database to better combat money laundering.”
Experts say the founder of Antinalysis also runs a darknet market for narcotics.
The Antinalysis homepage and chatter on the cybercrime forums indicates the service was created by a group of coders known as the Incognito Team. Tom Robinson, co-founder of the blockchain intelligence firm Elliptic, said the creator of Antinalysis is also one of the developers of Incognito Market, a darknet marketplace specializing in the sale of narcotics.
“Incognito was launched in late 2020, and accepts payments in both Bitcoin and Monero, a cryptoasset offering heightened anonymity,” Robinson said. “The launch of Antinalysis likely reflects the difficulties faced by the market and its vendors in cashing out their Bitcoin proceeds.”
