Nikita Kislitsin, formerly the head of network security for one of Russia’s top cybersecurity firms, was arrested last week in Kazakhstan in response to 10-year-old hacking charges from the U.S. Department of Justice. Experts say Kislitsin’s prosecution could soon put the Kazakhstan government in a sticky diplomatic position, as the Kremlin is already signaling that it intends to block his extradition to the United States.

Kislitsin is accused of hacking into the now-defunct social networking site Formspring in 2012, and conspiring with another Russian man convicted of stealing tens of millions of usernames and passwords from LinkedIn and Dropbox that same year.
In March 2020, the DOJ unsealed two criminal hacking indictments against Kislitsin, who was then head of security at Group-IB, a cybersecurity company that was founded in Russia in 2003 and operated there for more than a decade before relocating to Singapore.
Prosecutors in Northern California indicted Kislitsin in 2014 for his alleged role in stealing account data from Formspring. Kislitsin also was indicted in Nevada in 2013, but the Nevada indictment does not name his alleged victim(s) in that case.
However, documents unsealed in the California case indicate Kislitsin allegedly conspired with Yevgeniy Nikulin, a Russian man convicted in 2020 of stealing 117 million usernames and passwords from Dropbox, Formspring and LinkedIn in 2012. Nikulin is currently serving a seven-year sentence in the U.S. prison system.
As first reported by Cyberscoop in 2020, a trial brief in the California investigation identified Nikulin, Kislitsin and two alleged cybercriminals — Oleg Tolstikh and Oleksandr Vitalyevich Ieremenko — as being present during a 2012 meeting at a Moscow hotel, where participants allegedly discussed starting an internet café business.
A 2010 indictment out of New Jersey accuses Ieremenko and six others with siphoning nonpublic information from the U.S. Securities & Exchange Commission (SEC) and public relations firms, and making $30 million in illegal stock trades based on the proprietary information they stole.
[The U.S. Secret Service has an outstanding $1 million reward for information leading to the arrest of Ieremenko (Александр Витальевич Еременко), who allegedly went by the hacker handles “Zl0m” and “Lamarez.”]
Kislitsin was hired by Group-IB in January 2013, nearly six months after the Formspring hack. Group-IB has since moved its headquarters to Singapore, and in April 2023 the company announced it had fully exited the Russian market.
In a statement provided to KrebsOnSecurity, Group-IB said Mr. Kislitsin is no longer an employee, and that he now works for a Russian organization called FACCT, which stands for “Fight Against Cybercrime Technologies.”
“Dmitry Volkov, co-founder and CEO, sold his stake in Group-IB’s Russia-based business to the company’s local management,” the statement reads. “The stand-alone business in Russia has been operating under the new brand FACCT ever since and will continue to operate as a separate company with no connection to Group-IB.”
FACCT says on its website that it is a “Russian developer of technologies for combating cybercrime,” and that it works with clients to fight targeted attacks, data leaks, fraud, phishing and brand abuse. In a statement published online, FACCT said Kislitsin is responsible for developing its network security business, and that he remains under temporary detention in Kazakhstan “to study the basis for extradition arrest at the request of the United States.”
“According to the information we have, the claims against Kislitsin are not related to his work at FACCT, but are related to a case more than 10 years ago when Nikita worked as a journalist and independent researcher,” FACCT wrote.
From 2006 to 2012, Kislitsin was editor-in-chief of “Hacker,” a popular Russian-language monthly magazine that includes articles on information and network security, programming, and frequently features interviews with and articles penned by notable or wanted Russian hackers.
“We are convinced that there are no legal grounds for detention on the territory of Kazakhstan,” the FACCT statement continued. “The company has hired lawyers who have been providing Nikita with all the necessary assistance since last week, and we have also sent an appeal to the Consulate General of the Russian Federation in Kazakhstan to assist in protecting our employee.”
FACCT indicated that the Kremlin has already intervened in the case, and the Russian government claims Kislitsin is wanted on criminal charges in Russia and must instead be repatriated to his homeland.
“The FACCT emphasizes that the announcement of Nikita Kislitsin on the wanted list in the territory of the Russian Federation became known only today, June 28, 6 days after the arrest in Kazakhstan,” FACCT wrote. “The company is monitoring developments.”
The Kremlin followed a similar playbook in the case of Aleksei Burkov, a cybercriminal who long operated two of Russia’s most exclusive underground hacking forums. Burkov was arrested in 2015 by Israeli authorities, and the Russian government fought Burkov’s extradition to the U.S. for four years — even arresting and jailing an Israeli woman on phony drug charges to force a prisoner swap.
That effort ultimately failed: Burkov was sent to America, pleaded guilty, and was sentenced to nine years in prison.

Arkady Bukh is a U.S. attorney who has represented dozens of accused hackers from Russia and Eastern Europe who were extradited to the United States over the years. Bukh said Moscow is likely to turn the Kislitsin case into a diplomatic time bomb for Kazakhstan, which shares an enormous border and a great deal of cultural ties with Russia. A 2009 census found that Russians make up about 24 percent of the population of Kazakhstan.
“That would put Kazakhstan at a crossroads to choose between unity with Russia or going with the West,” Bukh said. “If that happens, Kazakhstan may have to make some very unpleasant decisions.”
Group-IB’s exodus from Russia comes as its former founder and CEO Ilya Sachkov remains languishing in a Russian prison, awaiting a farcical trial and an inevitable conviction on charges of treason. In September 2021, the Kremlin issued treason charges against Sachkov, although it has so far refused to disclose any details about the allegations.
Sachkov’s pending treason trial has been the subject of much speculation among denizens of Russian cybercrime forums, and the consensus seems to be that Sachkov and Group-IB were seen as a little too helpful to the DOJ in its various investigations involving top Russian hackers.
Indeed, since its inception in 2003, Group-IB’s researchers have helped to identify, disrupt and even catch a number of high-profile Russian hackers, most of whom got busted after years of criminal hacking because they made the unforgivable mistake of stealing from their own citizens.
When the indictments against Kislitsin were unsealed in 2020, Group-IB issued a lengthy statement attesting to his character and saying they would help him with his legal defense. As part of that statement, Group-IB noted that “representatives of the Group-IB company and, in particular, Kislitsin, in 2013, on their own initiative, met with employees of the US Department of Justice to inform them about the research work related to the underground, which was carried out by Kislitsin in 2012.”
Joseph James “PlugwalkJoe” O’Connor, a 24-year-old from the United Kingdom who earned his 15 minutes of fame by participating in the July 2020 hack of Twitter, has been sentenced to five years in a U.S. prison. That may seem like harsh punishment for a brief and very public cyber joy ride. But O’Connor also pleaded guilty in a separate investigation involving a years-long spree of cyberstalking and cryptocurrency theft enabled by “SIM swapping,” a crime wherein fraudsters trick a mobile provider into diverting a customer’s phone calls and text messages to a device they control.
Joseph “PlugwalkJoe” O’Connor, in a photo from a Globe Newswire press release Sept. 02, 2020, pitching O’Connor as a cryptocurrency expert and advisor.
On July 16, 2020 — the day after some of Twitter’s most recognizable and popular users had their accounts hacked and used to tweet out a bitcoin scam — KrebsOnSecurity observed that several social media accounts tied to O’Connor appeared to have inside knowledge of the intrusion. That story also noted that thanks to COVID-19 lockdowns at the time, O’Connor was stuck on an indefinite vacation at a popular resort in Spain.
Not long after the Twitter hack, O’Connor was quoted in The New York Times denying any involvement. “I don’t care,” O’Connor told The Times. “They can come arrest me. I would laugh at them. I haven’t done anything.”
Speaking with KrebsOnSecurity via Instagram instant message just days after the Twitter hack, PlugwalkJoe demanded that his real name be kept out of future blog posts here. After he was told that couldn’t be promised, he remarked that some people in his circle of friends had been known to hire others to deliver physical beatings on people they didn’t like.
O’Connor was still in Spain a year later when prosecutors in the Northern District of California charged him with conspiring to hack Twitter. At the same time, prosecutors in the Southern District of New York charged O’Connor with an impressive array of cyber offenses involving the exploitation of social media accounts, online extortion, cyberstalking, and the theft of cryptocurrency then valued at nearly USD $800,000.
In late April 2023, O’Connor was extradited from Spain to face charges in the United States. Two weeks later, he entered guilty pleas in both California and New York, admitting to all ten criminal charges levied against him. On June 23, O’Connor was sentenced to five years in prison.
PlugwalkJoe was part of a community that specialized in SIM-swapping victims to take over their online identities. Unauthorized SIM swapping is a scheme in which fraudsters trick or bribe employees at wireless phone companies into redirecting the target’s text messages and phone calls to a device they control.
From there, the attackers can reset the password for any of the victim’s online accounts that allow password resets via SMS. SIM swapping also lets attackers intercept one-time passwords needed for SMS-based multi-factor authentication (MFA).
O’Connor admitted to conducting SIM swapping attacks to take control over financial accounts tied to several cryptocurrency executives in May 2019, and to stealing digital currency currently valued at more than $1.6 million.
PlugwalkJoe also copped to SIM-swapping his way into the Snapchat accounts of several female celebrities and threatening to release nude photos found on their phones.
Victims who refused to give up social media accounts or submit to extortion demands were often visited with “swatting attacks,” wherein O’Connor and others would falsely report a shooting or hostage situation in the hopes of tricking police into visiting potentially lethal force on a target’s address.
Prosecutors said O’Connor even swatted and cyberstalked a 16-year-old girl, sending her nude photos and threatening to rape and/or murder her and her family.
In the case of the Twitter hack, O’Connor pleaded guilty to conspiracy to commit computer intrusions, conspiracy to commit wire fraud, and conspiracy to commit money laundering.
The account “@shinji,” a.k.a. “PlugWalkJoe,” tweeting a screenshot of Twitter’s internal tools interface, on July 15, 2020.
To resolve the case against him in New York, O’Connor pleaded guilty to conspiracy to commit computer intrusion, two counts of committing computer intrusions, making extortive communications, two counts of stalking, and making threatening communications.
In addition to the prison term, O’Connor was sentenced to three years of supervised release, and ordered to pay $794,012.64 in forfeiture.
To be clear, the Twitter hack of July 2020 did not involve SIM-swapping. Rather, Twitter said the intruders tricked a Twitter employee over the phone into providing access to internal tools.
Three others were charged along with O’Connor in the Twitter compromise. The alleged mastermind of the hack, then 17-year-old Graham Ivan Clarke from Tampa, Fla., pleaded guilty in 2021 and agreed to serve three years in prison, followed by three years probation.
This story is good reminder about the need to minimize your reliance on the mobile phone companies for securing your online identity. This means reducing the number of ways your life could be turned upside down if someone were to hijack your mobile phone number.
Most online services require users to validate a mobile phone number as part of setting up an account, but some services will let you remove your phone number after the fact. Those services that do you let you remove your phone number or disable SMS/phone calls for account recovery probably also offer more secure multi-factor authentication options, such as app-based one-time passwords and security keys. Check out 2fa.directory for a list of multi-factor options available across hundreds of popular sites and services.

If you operate a cybercrime business that relies on disseminating malicious software, you probably also spend a good deal of time trying to disguise or “crypt” your malware so that it appears benign to antivirus and security products. In fact, the process of “crypting” malware is sufficiently complex and time-consuming that most serious cybercrooks will outsource this critical function to a handful of trusted third parties. This story explores the history and identity behind Cryptor[.]biz, a long-running crypting service that is trusted by some of the biggest names in cybercrime.
Virtually all malware that is deployed for use in data stealing at some point needs to be crypted. This highly technical, laborious process involves iteratively altering the appearance and behavior of a malicious file until it no longer sets off alarm bells when scanned by different antivirus tools.
Experienced malware purveyors understand that if they’re not continuously crypting their malware before sending it out, then a lot more of whatever digital disease they are trying to spread is going to get flagged by security tools. In short, if you are running a cybercrime enterprise and you’re not equipped to handle this crypting process yourself, you probably need to pay someone else to do it for you.
Thanks to the high demand for reliable crypting services, there are countless cybercriminals who’ve hung out their shingles as crypting service providers. However, most of these people do not appear to be very good at what they do, because most are soon out of business.
One standout is Cryptor[.]biz. This service is actually recommended by the purveyors of the RedLine information stealer malware, which is a popular and powerful malware kit that specializes in stealing victim data and is often used to lay the groundwork for ransomware attacks. Cryptor[.]biz also has been recommended to customers of the Vidar information stealer malware family (via the malware’s Telegram support channels).
As good as Cryptor[.]biz may be at obfuscating malware, its proprietor does not appear to have done a great job covering his own tracks. The registration records for the website Cryptor[.]biz are hidden behind privacy protection services, but the site’s homepage says potential customers should register by visiting the domain crypt[.]guru, or by sending a Jabber instant message to the address “masscrypt@exploit.im.”
Crypt[.]guru’s registration records also are hidden, yet passive domain name system (DNS) records for both cryptor[.]biz and crypt[.]guru show that in 2018 the domains were forwarding incoming email to the address obelisk57@gmail.com.
Cyber intelligence firm Intel 471 reports that obelisk57@gmail.com was used to register an account on the forum Blacksoftware under the nickname “Kerens.” Meanwhile, the Jabber address masscrypt@exploit.im has been associated with the user Kerens on the Russian hacking forum Exploit from 2011 to the present day.
The login page for Cryptor dot biz contains several clues about who runs the service.
The very first post by Kerens on Exploit in 2011 was a negative review of a popular crypting service that predated Cryptor[.]biz called VIP Crypt, which Kerens accused of being “shitty” and unreliable. But Intel 471 finds that after his critical review of VIP Crypt, Kerens did not post publicly on Exploit again for another four years until October 2016, when they suddenly began advertising Cryptor[.]biz.
Intel 471 found that Kerens used the email address pepyak@gmail.com, which also was used to register Kerens accounts on the Russian language hacking forums Verified and Damagelab.
Ironically, Verified has itself been hacked multiple times over the years, with its private messages and user registration details leaked online. Those records indicate the user Kerens registered on Verified in March 2009 from an Internet address in Novosibirsk, a city in the southern Siberian region of Russia.
In 2010, someone with the username Pepyak on the Russian language affiliate forum GoFuckBiz[.]com shared that they typically split their time during the year between living in Siberia (during the milder months) and Thailand (when Novosibirsk is typically -15 °C/°5F).
For example, in one conversation about the best car to buy for navigating shoddy roads, Pepyak declared, “We have shitty roads in Siberia.” In January 2010, Pepyak asked the GoFuckBiz community where one might find a good USB-based modem in Phuket, Thailand.
DomainTools.com says the email address pepyak@gmail.com was used to register 28 domain names over the years, including a now-defunct Russian automobile sales website called “autodoska[.]biz.” DomainTools shows this website was registered in 2008 to a Yuri Churnov from Sevastpol, Crimea (prior to Russia’s annexation of Crimea in 2014, the peninsula was part of Ukraine).
The WHOIS records for autodoska[.]biz were changed in 2010 to Sergey Purtov (pepyak@gmail.com) from Yurga, a town in Russia’s Kemerovo Oblast, which is a relatively populous area in Western Siberia that is adjacent to Novosibirsk.

Many of the 28 domains registered to pepyak@gmail.com have another email address in their registration records: unforgiven57@mail.ru. According to DomainTools, the Unforgiven email address was used to register roughly a dozen domains, including three that were originally registered to Keren’s email address — pepyak@gmail.com (e.g., antivirusxp09[.]com).
One of the domains registered in 2006 to the address unforgiven57@mail.ru was thelib[.]ru, which for many years was a place to download pirated e-books. DomainTools says thelib[.]ru was originally registered to a Sergey U Purtov.
Most of the two-dozen domains registered to pepyak@gmail.com shared a server at one point with a small number of other domains, including mobile-soft[.]su, which was registered to the email address spurtov@gmail.com.
CDEK, an express delivery company based in Novosibirsk, was apparently hacked at some point because cyber intelligence firm Constella Intelligence found that its database shows the email address spurtov@gmail.com was assigned to a Sergey Yurievich Purtov (Сергей Юрьевич Пуртов).
DomainTools says the same phone number in the registration records for autodoska[.]biz (+7.9235059268) was used to secure two other domains — bile[.]ru and thelibrary[.]ru, both of which were registered to a Sergey Y Purtov.
A search on the phone number 79235059268 in Skype reveals these digits belong to a “Sergey” from Novosibirsk with the now-familiar username — Pepyak.
Bringing things full circle, Constella Intelligence shows that various online accounts tied to the email address unforgiven57@mail.ru frequently relied on the somewhat unique password, “plk139t51z.” Constella says that same password was used for just a handful of other email addresses, including gumboldt@gmail.com.
Hacked customer records from CDEK show gumboldt@gmail.com was tied to a customer named Sergey Yurievich Purtov. DomainTools found that virtually all of the 15 domain names registered to gumboldt@gmail.com (including the aforementioned mobile-soft[.]su) were at one point registered to spurtov@gmail.com.
Intel 471 reports that gumboldt@gmail.com was used in 2009 to register a user by the nickname “Kolumb” on the Russian hacking forum Antichat. From Kolumb’s posts on Antichat, it seems this user was mostly interested in buying access to compromised computers inside of Russia.
Then in December 2009, Kolumb said they were in desperate need of a reliable crypting service or full-time cryptor.
“We need a person who will crypt software every day, sometimes even a couple of times a day,” Kolumb wrote on Antichat.
Mr. Purtov did not respond to requests for comment sent to any of the email addresses referenced in this report. Mail.ru responded that the email address spurtov@mail.ru is no longer active.
As KrebsOnSecurity opined on Mastodon earlier this week, it makes a lot of sense for cybersecurity researchers and law enforcement alike to focus attention on the top players in the crypting space — for several reasons. Most critically, the cybercriminals offering time-tested crypting services also tend to be among the most experienced and connected malicious coders on the planet.
Think of it this way: By definition, a crypting service scans and examines all types of malware before those new nasties are first set loose in the wild. This fact alone should make these criminal enterprises a primary target of cybersecurity firms looking to gain more timely intelligence about new malware.
Also, a review of countless posts and private messages from Pepyak and other crypting providers shows that a successful crypting service will have direct and frequent contact with some of the world’s most advanced malware authors.
In short, infiltrating or disrupting a trusted crypting service can be an excellent way to slow down or even sideline a large number of cybercrime operations all at once.

This Service Helps Malware Authors Fix Flaws in Their Code
Antivirus is Dead: Long Live Antivirus!
Code-signing certificates are supposed to help authenticate the identity of software publishers, and provide cryptographic assurance that a signed piece of software has not been altered or tampered with. Both of these qualities make stolen or ill-gotten code-signing certificates attractive to cybercriminal groups, who prize their ability to add stealth and longevity to malicious software. This post is a deep dive on “Megatraffer,” a veteran Russian hacker who has practically cornered the underground market for malware focused code-signing certificates since 2015.
One of Megatraffer’s ads on an English-language cybercrime forum.
A review of Megatraffer’s posts on Russian crime forums shows this user began peddling individual stolen code-signing certs in 2015 on the Russian-language forum Exploit, and soon expanded to selling certificates for cryptographically signing applications and files designed to run in Microsoft Windows, Java, Adobe AIR, Mac and Microsoft Office.
Megatraffer explained that malware purveyors need a certificate because many antivirus products will be far more interested in unsigned software, and because signed files downloaded from the Internet don’t tend to get blocked by security features built into modern web browsers. Additionally, newer versions of Microsoft Windows will complain with a bright yellow or red alert message if users try to install a program that is not signed.
“Why do I need a certificate?” Megatraffer asked rhetorically in their Jan. 2016 sales thread on Exploit. “Antivirus software trusts signed programs more. For some types of software, a digital signature is mandatory.”
At the time, Megatraffer was selling unique code-signing certificates for $700 apiece, and charging more than twice that amount ($1,900) for an “extended validation” or EV code-signing cert, which is supposed to only come with additional identity vetting of the certificate holder. According to Megatraffer, EV certificates were a “must-have” if you wanted to sign malicious software or hardware drivers that would reliably work in newer Windows operating systems.
Part of Megatraffer’s ad. Image: Ke-la.com.
Megatraffer has continued to offer their code-signing services across more than a half-dozen other Russian-language cybercrime forums, mostly in the form of sporadically available EV and non-EV code-signing certificates from major vendors like Thawte and Comodo.
More recently, it appears Megatraffer has been working with ransomware groups to help improve the stealth of their malware. Shortly after Russia invaded Ukraine in February 2022, someone leaked several years of internal chat logs from the Conti ransomware gang, and those logs show Megatraffer was working with the group to help code-sign their malware between July and October 2020.
According to cyber intelligence firm Intel 471, Megatraffer has been active on more than a half-dozen crime forums from September 2009 to the present day. And on most of these identities, Megatraffer has used the email address 774748@gmail.com. That same email address also is tied to two forum accounts for a user with the handle “O.R.Z.”
Constella Intelligence, a company that tracks exposed databases, finds that 774748@gmail.com was used in connection with just a handful of passwords, but most frequently the password “featar24“. Pivoting off of that password reveals a handful of email addresses, including akafitis@gmail.com.
Intel 471 shows akafitis@gmail.com was used to register another O.R.Z. user account — this one on Verified[.]ru in 2008. Prior to that, akafitis@gmail.com was used as the email address for the account “Fitis,” which was active on Exploit between September 2006 and May 2007. Constella found the password “featar24” also was used in conjunction with the email address spampage@yandex.ru, which is tied to yet another O.R.Z. account on Carder[.]su from 2008.
The email address akafitis@gmail.com was used to create a Livejournal blog profile named Fitis that has a large bear as its avatar. In November 2009, Fitis wrote, “I am the perfect criminal. My fingerprints change beyond recognition every few days. At least my laptop is sure of it.”
Fitis’s Livejournal account. Image: Archive.org.
Fitis’s real-life identity was exposed in 2010 after two of the biggest sponsors of pharmaceutical spam went to war with each other, and large volumes of internal documents, emails and chat records seized from both spam empires were leaked to this author. That protracted and public conflict formed the backdrop of my 2014 book — “Spam Nation: The Inside Story of Organized Cybercrime, from Global Epidemic to Your Front Door.”
One of the leaked documents included a Microsoft Excel spreadsheet containing the real names, addresses, phone numbers, emails, street addresses and WebMoney addresses for dozens of top earners in Spamit — at the time the most successful pharmaceutical spam affiliate program in the Russian hacking scene and one that employed most of the top Russian botmasters.
That document shows Fitis was one of Spamit’s most prolific recruiters, bringing more than 75 affiliates to the Spamit program over several years prior to its implosion in 2010 (and earning commissions on any future sales from all 75 affiliates).
The document also says Fitis got paid using a WebMoney account that was created when its owner presented a valid Russian passport for a Konstantin Evgenievich Fetisov, born Nov. 16, 1982 and residing in Moscow. Russian motor vehicle records show two different vehicles are registered to this person at the same Moscow address.
The most interesting domain name registered to the email address spampage@yahoo.com, fittingly enough, is fitis[.]ru, which DomainTools.com says was registered in 2005 to a Konstantin E. Fetisov from Moscow.
The Wayback Machine at archive.org has a handful of mostly blank pages indexed for fitis[.]ru in its early years, but for a brief period in 2007 it appears this website was inadvertently exposing all of its file directories to the Internet.
One of the exposed files — Glavmed.html — is a general invitation to the infamous Glavmed pharmacy affiliate program, a now-defunct scheme that paid tens of millions of dollars to affiliates who advertised online pill shops mainly by hacking websites and manipulating search engine results. Glavmed was operated by the same Russian cybercriminals who ran the Spamit program.
A Google translated ad circa 2007 recruiting for the pharmacy affiliate program Glavmed, which told interested applicants to contact the ICQ number used by Fitis, a.k.a. MegaTraffer. Image: Archive.org.
Archive.org shows the fitis[.]ru webpage with the Glavmed invitation was continuously updated with new invite codes. In their message to would-be Glavmed affiliates, the program administrator asked applicants to contact them at the ICQ number 165540027, which Intel 471 found was an instant messenger address previously used by Fitis on Exploit.
The exposed files in the archived version of fitis[.]ru include source code for malicious software, lists of compromised websites used for pharmacy spam, and a handful of what are apparently personal files and photos. Among the photos is a 2007 image labeled merely “fitis.jpg,” which shows a bespectacled, bearded young man with a ponytail standing next to what appears to be a newly-married couple at a wedding ceremony.
Mr. Fetisov did not respond to requests for comment.
As a veteran organizer of affiliate programs, Fitis did not waste much time building a new moneymaking collective after Spamit closed up shop. New York City-based cyber intelligence firm Flashpoint found that Megatraffer’s ICQ was the contact number for Himba[.]ru, a cost-per-acquisition (CPA) program launched in 2012 that paid handsomely for completed application forms tied to a variety of financial instruments, including consumer credit cards, insurance policies, and loans.
“Megatraffer’s entrenched presence on cybercrime forums strongly suggests that malicious means are used to source at least a portion of traffic delivered to HIMBA’s advertisers,” Flashpoint observed in a threat report on the actor.
Intel 471 finds that Himba was an active affiliate program until around May 2019, when it stopping paying its associates.

Flashpoint notes that in September 2015, Megatraffer posted a job ad on Exploit seeking experienced coders to work on browser plugins, installers and “loaders” — basically remote access trojans (RATs) that establish communication between the attacker and a compromised system.
“The actor specified that he is looking for full-time, onsite help either in his Moscow or Kiev locations,” Flashpoint wrote.
Social networks are constantly battling inauthentic bot accounts that send direct messages to users promoting scam cryptocurrency investment platforms. What follows is an interview with a Russian hacker responsible for a series of aggressive crypto spam campaigns that recently prompted several large Mastodon communities to temporarily halt new registrations. According to the hacker, their spam software has been in private use until the last few weeks, when it was released as open source code.
Renaud Chaput is a freelance programmer working on modernizing and scaling the Mastodon project infrastructure — including joinmastodon.org, mastodon.online, and mastodon.social. Chaput said that on May 4, 2023, someone unleashed a spam torrent targeting users on these Mastodon communities via “private mentions,” a kind of direct messaging on the platform.
The messages said recipients had earned an investment credit at a cryptocurrency trading platform called moonxtrade[.]com. Chaput said the spammers used more than 1,500 Internet addresses across 400 providers to register new accounts, which then followed popular accounts on Mastodon and sent private mentions to the followers of those accounts.
Since then, the same spammers have used this method to advertise more than 100 different crypto investment-themed domains. Chaput said that at one point this month the volume of bot accounts being registered for the crypto spam campaign started overwhelming the servers that handle new signups at Mastodon.social.
“We suddenly went from like three registrations per minute to 900 a minute,” Chaput said. “There was nothing in the Mastodon software to detect that activity, and the protocol is not designed to handle this.”
One of the crypto investment scam messages promoted in the spam campaigns on Mastodon this month.
Seeking to gain a temporary handle on the spam wave, Chaput said he briefly disabled new account registrations on mastodon.social and mastondon.online. Shortly after that, those same servers came under a sustained distributed denial-of-service (DDoS) attack.
Chaput said whoever was behind the DDoS was definitely not using point-and-click DDoS tools, like a booter or stresser service.
“This was three hours non-stop, 200,000 to 400,000 requests per second,” Chaput said of the DDoS. “At first, they were targeting one path, and when we blocked that they started to randomize things. Over three hours the attack evolved several times.”
Chaput says the spam waves have died down since they retrofitted mastodon.social with a CAPTCHA, those squiggly letter and number combinations designed to stymie automated account creation tools. But he’s worried that other Mastodon instances may not be as well-staffed and might be easy prey for these spammers.
“We don’t know if this is the work of one person, or if this is [related to] software or services being sold to others,” Chaput told KrebsOnSecurity. “We’re really impressed by the scale of it — using hundreds of domains and thousands of Microsoft email addresses.”
Chaput said a review of their logs indicates many of the newly registered Mastodon spam accounts were registered using the same 0auth credentials, and that a domain common to those credentials was quot[.]pw.
The domain quot[.]pw has been registered and abandoned by several parties since 2014, but the most recent registration data available through DomainTools.com shows it was registered in March 2020 to someone in Krasnodar, Russia with the email address edgard011012@gmail.com.
This email address is also connected to accounts on several Russian cybercrime forums, including “__edman__,” who had a history of selling “logs” — large amounts of data stolen from many bot-infected computers — as well as giving away access to hacked Internet of Things (IoT) devices.
In September 2018, a user by the name “ципа” (phonetically “Zipper” in Russian) registered on the Russian hacking forum Lolzteam using the edgard0111012@gmail.com address. In May 2020, Zipper told another Lolzteam member that quot[.]pw was their domain. That user advertised a service called “Quot Project” which said they could be hired to write programming scripts in Python and C++.
“I make Telegram bots and other rubbish cheaply,” reads one February 2020 sales thread from Zipper.

Clicking the “open chat in Telegram” button on Zipper’s Lolzteam profile page launched a Telegram instant message chat window where the user Quotpw responded almost immediately. Asked if they were aware their domain was being used to manage a spam botnet that was pelting Mastodon instances with crypto scam spam, Quotpw confirmed the spam was powered by their software.
“It was made for a limited circle of people,” Quotpw said, noting that they recently released the bot software as open source on GitHub.
Quotpw went on to say the spam botnet was powered by well more than the hundreds of IP addresses tracked by Chaput, and that these systems were mostly residential proxies. A residential proxy generally refers to a computer or mobile device running some type of software that enables the system to be used as a pass-through for Internet traffic from others.
Very often, this proxy software is installed surreptitiously, such as through a “Free VPN” service or mobile app. Residential proxies also can refer to households protected by compromised home routers running factory-default credentials or outdated firmware.
Quotpw maintains they have earned more than $2,000 sending roughly 100,000 private mentions to users of different Mastodon communities over the past few weeks. Quotpw said their conversion rate for the same bot-powered direct message spam on Twitter is usually much higher and more profitable, although they conceded that recent adjustments to Twitter’s anti-bot CAPTCHA have put a crimp in their Twitter earnings.
“My partners (I’m programmer) lost time and money while ArkoseLabs (funcaptcha) introduced new precautions on Twitter,” Quotpw wrote in a Telegram reply. “On Twitter, more spam and crypto scam.”
Asked whether they felt at all conflicted about spamming people with invitations to cryptocurrency scams, Quotpw said in their hometown “they pay more for such work than in ‘white’ jobs” — referring to legitimate programming jobs that don’t involve malware, botnets, spams and scams.
“Consider salaries in Russia,” Quotpw said. “Any spam is made for profit and brings illegal money to spammers.”
Shortly after edgard011012@gmail.com registered quot[.]pw, the WHOIS registration records for the domain were changed again, to msr-sergey2015@yandex.ru, and to a phone number in Austria: +43.6607003748.
Constella Intelligence, a company that tracks breached data, finds that the address msr-sergey2015@yandex.ru has been associated with accounts at the mobile app site aptoide.com (user: CoolappsforAndroid) and vimeworld.ru that were created from different Internet addresses in Vienna, Austria.
A search in Skype on that Austrian phone number shows it belongs to a Sergey Proshutinskiy who lists his location as Vienna, Austria. The very first result that comes up when one searches that unusual name in Google is a LinkedIn profile for a Sergey Proshutinskiy from Vienna, Austria.
Proshutinskiy’s LinkedIn profile says he is a Class of 2024 student at TGM, which is a state-owned, technical and engineering school in Austria. His resume also says he is a data science intern at Mondi Group, an Austrian manufacturer of sustainable packaging and paper.
Mr. Proshutinskiy did not respond to requests for comment.
Quotpw denied being Sergey, and said Sergey was a friend who registered the domain as a birthday present and favor last year.
“Initially, I bought it for 300 rubles,” Quotpw explained. “The extension cost 1300 rubles (expensive). I waited until it expired and forgot to buy it. After that, a friend (Sergey) bought [the] domain and transferred access rights to me.”
“He’s not even an information security specialist,” Quotpw said of Sergey. “My friends do not belong to this field. None of my friends are engaged in scams or other black [hat] activities.”
It may seem unlikely that someone would go to all this trouble to spam Mastodon users over several weeks using an impressive number of resources — all for just $2,000 in profit. But it is likely that whoever is actually running the various crypto scam platforms advertised by Quotpw’s spam messages pays handsomely for any investments generated by their spam.
According to the FBI, financial losses from cryptocurrency investment scams dwarfed losses for all other types of cybercrime in 2022, rising from $907 million in 2021 to $2.57 billion last year.
Update, May 25, 10:30 a.m.: Corrected attribution of the Austrian school TGM.
A Russian man identified by KrebsOnSecurity in January 2022 as a prolific and vocal member of several top ransomware groups was the subject of two indictments unsealed by the Justice Department today. U.S. prosecutors say Mikhail Pavolovich Matveev, a.k.a. “Wazawaka” and “Boriselcin” worked with three different ransomware gangs that extorted hundreds of millions of dollars from companies, schools, hospitals and government agencies.
An FBI wanted poster for Matveev.
Indictments returned in New Jersey and the District of Columbia allege that Matveev was involved in a conspiracy to distribute ransomware from three different strains or affiliate groups, including Babuk, Hive and LockBit.
The indictments allege that on June 25, 2020, Matveev and his LockBit co-conspirators deployed LockBit ransomware against a law enforcement agency in Passaic County, New Jersey. Prosecutors say that on May 27, 2022, Matveev conspired with Hive to ransom a nonprofit behavioral healthcare organization headquartered in Mercer County, New Jersey. And on April 26, 2021, Matveev and his Babuk gang allegedly deployed ransomware against the Metropolitan Police Department in Washington, D.C.
Meanwhile, the U.S. Department of Treasury has added Matveev to its list of persons with whom it is illegal to transact financially. Also, the U.S. State Department is offering a $10 million reward for the capture and/or prosecution of Matveev, although he is unlikely to face either as long as he continues to reside in Russia.
In a January 2021 discussion on a top Russian cybercrime forum, Matveev’s alleged alter ego Wazawaka said he had no plans to leave the protection of “Mother Russia,” and that traveling abroad was not an option for him.
“Mother Russia will help you,” Wazawaka concluded. “Love your country, and you will always get away with everything.”
In January 2022, KrebsOnSecurity published Who is the Network Access Broker ‘Wazawaka,’ which followed clues from Wazawaka’s many pseudonyms and contact details on the Russian-language cybercrime forums back to a 33-year-old Mikhail Matveev from Abaza, RU (the FBI says his date of birth is Aug. 17, 1992).
A month after that story ran, a man who appeared identical to the social media photos for Matveev began posting on Twitter a series of bizarre selfie videos in which he lashed out at security journalists and researchers (including this author), while using the same Twitter account to drop exploit code for a widely-used virtual private networking (VPN) appliance.
“Hello Brian Krebs! You did a really great job actually, really well, fucking great — it’s great that journalism works so well in the US,” Matveev said in one of the videos. “By the way, it is my voice in the background, I just love myself a lot.”
Prosecutors allege Matveev used a dizzying stream of monikers on the cybercrime forums, including “Boriselcin,” a talkative and brash personality who was simultaneously the public persona of Babuk, a ransomware affiliate program that surfaced on New Year’s Eve 2020.
Previous reporting here revealed that Matveev’s alter egos included “Orange,” the founder of the RAMP ransomware forum. RAMP stands for “Ransom Anon Market Place, and analysts at the security firm Flashpoint say the forum was created “directly in response to several large Dark Web forums banning ransomware collectives on their site following the Colonial Pipeline attack by ransomware group ‘DarkSide.”
As noted in last year’s investigations into Matveev, his alleged cybercriminal handles all were driven by a uniquely communitarian view that when organizations being held for ransom decline to cooperate or pay up, any data stolen from the victim should be published on the Russian cybercrime forums for all to plunder — not privately sold to the highest bidder.
In thread after thread on the crime forum XSS, Matveev’s alleged alias “Uhodiransomwar” could be seen posting download links to databases from companies that have refused to negotiate after five days.
Matveev is charged with conspiring to transmit ransom demands, conspiring to damage protected computers, and intentionally damaging protected computers. If convicted, he faces more than 20 years in prison.
