The Not-So-Secret Network Access Broker x999xx

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

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

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

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

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

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

ALIAS: MAXNM

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

CONFIRMATION

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

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

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

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

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

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

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

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

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

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

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

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

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

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

How to Protect Yourself from Vishing

“Vishing” occurs when criminals cold-call victims and attempt to persuade them to divulge personal information over the phone. These scammers are generally after credit card numbers and personal identifying information, which can then be used to commit financial theft. Vishing can occur both on your landline phone or via your cell phone.

The term is a combination of “voice,” and “phishing,” which is the use of spoofed emails to trick targets into clicking malicious links. Rather than email, vishing generally relies on automated phone calls that instruct targets to provide account numbers. Techniques scammers use to get your phone numbers include:

  • Data Breaches: Scammers often obtain phone numbers from data breaches where personal information is exposed and sold on the dark web.
  • Public Records: Phone numbers can be found in public records, such as court documents, voter registration lists, and property records, which are often accessible online.
  • Social Media: Many people share their contact information on social media profiles or posts, making it easy for scammers to collect phone numbers.
  • Online Surveys and Contests: Scammers create fake online surveys or contests that require participants to enter their phone numbers, which are then harvested for vishing.
  • Dumpster Diving: Physical documents thrown away without shredding, such as old phone bills or bank statements, can provide scammers with phone numbers. Once a visher has the list, he can program the numbers into his system for a more targeted attack.
  • Wardialing: A visher uses an automated system to target specific area codes with a phone call involving local or regional banks or credit unions. When someone answers the phone a generic or targeted recording begins, requesting that the listener enter a bank account, credit, or debit card number and PIN.

Once vishers have phone numbers, they employ various strategies to deceive their targets and obtain valuable personal information:

  • VoIP: Voice over Internet Protocol (VoIP) facilitates vishing by enabling vishers to easily spoof caller IDs, use automated dialing systems, and leverage AI-powered voice manipulation, all while operating from virtually anywhere with an internet connection. This combination of technologies makes it easier for scammers to appear legitimate and efficiently target numerous victims.
  • Caller ID Spoofing: Caller ID spoofing works by manipulating the caller ID information that appears on the recipient’s phone, making it seem as though the call is coming from a trusted or local source. Scammers use specialized software or VoIP services to alter the displayed number, which can mimic the number of a reputable institution, such as a bank or government agency.
  • Social Engineering: In live calls, vishers use social engineering techniques to build trust and manipulate the target into divulging personal information. They might pose as customer service representatives, tech support agents, or officials from financial institutions to convince you to hand over personal information.
  • Voice Manipulation Technology: Advanced AI-powered voice manipulation tools can mimic the voices of known individuals or create convincing synthetic voices, adding credibility to the call.
  • Urgency and Threats: Vishers often create a sense of urgency or fear, claiming immediate action is required to prevent serious consequences, such as account closure, legal action, or financial loss.

To protect yourself from vishing scams, you should:

  • Educate Yourself: Knowledge is the key to defending yourself from vishing. The more you understand it, the better off you’ll be, so read up on vishing incidents. As this crime becomes more sophisticated, you’ll want to stay up to date.
  • Use Call Blocking Tools: Utilize call blocking and caller ID spoofing detection tools offered by your phone service provider or third-party apps to filter out potential scam calls.
  • Be Skeptical of Caller ID: With phone spoofing, caller ID is no longer trustworthy. Since caller ID can be tampered with, don’t let it offer a false sense of security.
  • Do Not Share Personal Information: Never provide personal information, such as Social Security numbers, credit card details, or passwords, to unsolicited callers.
  • End the Call: If you receive a phone call from a person or a recording requesting personal information, hang up. If the call purports to be coming from a trusted organization, call that entity directly to confirm their request.
  • Report Suspicious Activity: Call your bank and report any fraud attempts immediately, noting what was said, what information was requested, and, if possible, the phone number or area code of the caller. Also report any suspicious calls to relevant authorities, such as the Federal Trade Commission (FTC), to help prevent others from falling victim to the same scams.

Staying vigilant and informed is your best defense against vishing scams. By verifying caller identities, being skeptical of unsolicited requests for personal information, and using call-blocking tools, you can significantly reduce your risk of falling victim to these deceptive practices. Additionally, investing in identity theft protection services can provide an extra layer of security. These services monitor your personal information for suspicious activity and offer assistance in recovering from identity theft, giving you peace of mind in an increasingly digital world. Remember, proactive measures and awareness are key to safeguarding your personal information against vishing threats.

Enhancing AI Security Incident Response Through Collaborative Exercises

Take-aways from a tabletop exercise led by CISA's Joint Cyber Defense Collaborative (JCDC), which brought together government and industry leaders to enhance our collective ability to respond to AI-related security incidents.

KrebsOnSecurity Threatened with Defamation Lawsuit Over Fake Radaris CEO

On March 8, 2024, KrebsOnSecurity published a deep dive on the consumer data broker Radaris, showing how the original owners are two men in Massachusetts who operated multiple Russian language dating services and affiliate programs, in addition to a dizzying array of people-search websites. The subjects of that piece are threatening to sue KrebsOnSecurity for defamation unless the story is retracted. Meanwhile, their attorney has admitted that the person Radaris named as the CEO from its inception is a fabricated identity.

Radaris is just one cog in a sprawling network of people-search properties online that sell highly detailed background reports on U.S. consumers and businesses. Those reports typically include the subject’s current and previous addresses, partial Social Security numbers, any known licenses, email addresses and phone numbers, as well as the same information for any of their immediate relatives.

Radaris has a less-than-stellar reputation when it comes to responding to consumers seeking to have their reports removed from its various people-search services. That poor reputation, combined with indications that the true founders of Radaris have gone to extraordinary lengths to conceal their stewardship of the company, was what prompted KrebsOnSecurity to investigate the origins of Radaris in the first place.

On April 18, KrebsOnSecurity received a certified letter (PDF) from Valentin “Val” Gurvits, an attorney with the Boston Law Group, stating that KrebsOnSecurity would face a withering defamation lawsuit unless the Radaris story was immediately retracted and an apology issued to the two brothers named in the story as co-founders.

That March story worked backwards from the email address used to register radaris.com, and charted an impressive array of data broker companies created over the past 15 years by Massachusetts residents Dmitry and Igor Lubarsky (also sometimes spelled Lybarsky or Lubarski). Dmitry goes by “Dan,” and Igor uses the name “Gary.”

Those businesses included numerous websites marketed to Russian-speaking people who are new to the United States, such as russianamerica.com, newyork.ru, russiancleveland.com, russianla.com, russianmiami.com, etc. Other domains connected to the Lubarskys included Russian-language dating and adult websites, as well as affiliate programs for their international calling card businesses.

A mind map of various entities apparently tied to Radaris and the company’s co-founders. Click to enlarge.

The story on Radaris noted that the Lubarsky brothers registered most of their businesses using a made-up name — “Gary Norden,” sometimes called Gary Nord or Gary Nard.

Mr. Gurvits’ letter stated emphatically that my reporting was lazy, mean-spirited, and obviously intended to smear the reputation of his clients. By way of example, Mr. Gurvits said the Lubarskys were actually Ukrainian, and that the story painted his clients in a negative light by insinuating that they were somehow associated with Radaris and with vaguely nefarious elements in Russia.

But more to the point, Mr. Gurvits said, neither of his clients were Gary Norden, and neither had ever held any leadership positions at Radaris, nor were they financial beneficiaries of the company in any way.

“Neither of my clients is a founder of Radaris, and neither of my clients is the CEOs of Radaris,” Gurvits wrote. “Additionally, presently and going back at least the past 10 years, neither of my clients are (or were) officers or employees of Radaris. Indeed, neither of them even owns (or ever owned) any equity in Radaris. In intentional disregard of these facts, the Article implies that my clients are personally responsible for Radaris’ actions. Therefore, you intentionally caused all negative allegations in the Article made with respect to Radaris to be imputed against my clients personally.”

Dan Lubarsky’s Facebook page, just prior to the March 8 story about Radaris, said he was from Moscow.

We took Mr. Gurvits’ word on the ethnicity of his clients, and adjusted the story to remove a single mention that they were Russian. We did so even though Dan Lubarsky’s own Facebook page said (until recently) that he was from Moscow, Russia.

KrebsOnSecurity asked Mr. Gurvits to explain precisely which other details in the story were incorrect, and replied that we would be happy to update the story with a correction if they could demonstrate any errors of fact or omission.

We also requested specifics about several aspects of the story, such as the identity of the current Radaris CEO — listed on the Radaris website as “Victor K.” Mr. Gurvits replied that Radaris is and always has been based in Ukraine, and that the company’s true founder “Eugene L” is based there.

While Radaris has claimed to have offices in Massachusetts, Cyprus and Latvia, its website has never mentioned Ukraine. Mr. Gurvits has not responded to requests for more information about the identities of “Eugene L” or “Victor K.”

Gurvits said he had no intention of doing anyone’s reporting for them, and that the Lubarskys were going to sue KrebsOnSecurity for defamation unless the story was retracted in full. KrebsOnSecurity replied that journalists often face challenges to things that they report, but it is more than rare for one who makes a challenge to take umbrage at being asked for supporting information.

On June 13, Mr. Gurvits sent another letter (PDF) that continued to claim KrebsOnSecurity was defaming his clients, only this time Gurvits said his clients would be satisfied if KrebsOnSecurity just removed their names from the story.

“Ultimately, my clients don’t care what you say about any of the websites or corporate entities in your Article, as long as you completely remove my clients’ names from the Article and cooperate with my clients to have copies of the Article where my clients’ names appear removed from the Internet,” Mr. Gurvits wrote.

MEET THE FAKE RADARIS CEO

The June 13 letter explained that the name Gary Norden was a pseudonym invented by the Radaris marketing division, but that neither of the Lubarsky brothers were Norden.

This was a startling admission, given that Radaris has quoted the fictitious Gary Norden in press releases published and paid for by Radaris, and in news media stories where the company is explicitly seeking money from investors. In other words, Radaris has been misrepresenting itself to investors from the beginning. Here’s a press release from Radaris that was published on PR Newswire in April 2011:

A press release published by Radaris in 2011 names the CEO of Radaris as Gary Norden, which was a fake name made up by Radaris’ marketing department.

In April 2014, the Boston Business Journal published a story (PDF) about Radaris that extolled the company’s rapid growth and considerable customer base. The story noted that, “to date, the company has raised less than $1 million from Cyprus-based investment company Difive.”

“We live in a world where information becomes much more broad and much more available every single day,” the Boston Business Journal quoted Radaris’ fake CEO Gary Norden, who by then had somehow been demoted from CEO to vice president of business development.

A Boston Business Journal story from April 2014 quotes the fictitious Radaris CEO Gary Norden.

“We decided there needs to be a service that allows for ease of monitoring of information about people,” the fake CEO said. The story went on to say Radaris was seeking to raise between $5 million and $7 million from investors in the ensuing months.

THE BIG LUBARSKY

In his most recent demand letter, Mr. Gurvits helpfully included resumes for both of the Lubarsky brothers.

Dmitry Lubarsky’s resume states he is the owner of Difive.com, a startup incubator for IT companies. Recall that Difive is the same company mentioned by the fake Radaris CEO in the 2014 Boston Business Journal story, which said Difive was the company’s initial and sole investor.

Difive’s website in 2016 said it had offices in Boston, New York, San Francisco, Riga (Latvia) and Moscow (nothing in Ukraine). Meanwhile, DomainTools.com reports difive.com was originally registered in 2007 to the fictitious Gary Norden from Massachusetts.

Archived copies of the Difive website from 2017 include a “Portfolio” page indexing all of the companies in which Difive has invested. That list, available here, includes virtually every “Gary Norden” domain name mentioned in my original report, plus a few that escaped notice earlier.

Dan Lubarsky’s resume says he was CEO of a people search company called HumanBook. The Wayback machine at archive.org shows the Humanbook domain (humanbook.com) came online around April 2008, when the company was still in “beta” mode.

By August 2008, however, humanbook.com had changed the name advertised on its homepage to Radaris Beta. Eventually, Humanbook simply redirected to radaris.com.

Archive.org’s record of humanbook.com from 2008, just after its homepage changed to Radaris Beta.

Astute readers may notice that the domain radaris.com is not among the companies listed as Difive investments. However, passive domain name system (DNS) records from DomainTools show that between October 2023 and March 2024 radaris.com was hosted alongside all of the other Gary Norden domains at the Internet address range 38.111.228.x.

That address range simultaneously hosted every domain mentioned in this story and in the original March 2024 report as connected to email addresses used by Gary Norden, including radaris.com, radaris.ru, radaris.de, difive.com, privet.ru, blog.ru, comfi.com, phoneowner.com, russianamerica.com, eprofit.com, rehold.com, homeflock.com, humanbook.com and dozens more. A spreadsheet of those historical DNS entries for radaris.com is available here (.csv).

Image: DomainTools.com

The breach tracking service Constella Intelligence finds just two email addresses ending in difive.com have been exposed in data breaches over the years: dan@difive.com, and gn@difive.com. Presumably, “gn” stands for Gary Norden.

A search on the email address gn@difive.com via the breach tracking service osint.industries reveals this address was used to create an account at Airbnb under the name Gary, with the last four digits of the account’s phone number ending in “0001.”

Constella Intelligence finds gn@difive.com was associated with the Massachusetts number 617-794-0001, which was used to register accounts for “Igor Lybarsky” from Wellesley or Sherborn, Ma. at multiple online businesses, including audiusa.com and the designer eyewear store luxottica.com.

The phone number 617-794-0001 also appears for a “Gary Nard” user at russianamerica.com. Igor Lubarsky’s resume says he was the manager of russianamerica.com.

DomainTools finds 617-794-0001 is connected to registration records for three domains, including paytone.com, a domain that Dan Lubarsky’s resume says he managed. DomainTools also found that number on the registration records for trustoria.com, another major consumer data broker that has an atrocious reputation, according to the Better Business Bureau.

Dan Lubarsky’s resume says he was responsible for several international telecommunications services, including the website comfi.com. DomainTools says the phone number connected to that domain — 617-952-4234 — was also used on the registration records for humanbook.net/biz/info/mobi/us, as well as for radaris.me, radaris.in, and radaris.tel.

Two other key domains are connected to that phone number. The first is barsky.com, which is the website for Barsky Estate Realty Trust (PDF), a real estate holding company controlled by the Lubarskys. Naturally, DomainTools finds barsky.com also was registered to a Gary Norden from Massachusetts. But the organization listed in the barsky.com registration records is Comfi Inc., a VOIP communications firm that Dan Lubarsky’s resume says he managed.

The other domain of note is unipointtechnologies.com. Dan Lubarsky’s resume says he was the CEO of Wellesley Hills, Mass-based Unipoint Technology Inc. In 2012, Unipoint was fined $179,000 by the U.S. Federal Communications Commission, which said the company had failed to apply for a license to provide international telecommunications services.

A pandemic assistance loan granted in 2020 to Igor Lybarsky of Sherborn, Ma. shows he received the money to an entity called Norden Consulting.

Notice the name on the recipient of this government loan for Igor Lybarsky from Sherborn, Ma: Norden Consulting. 

PATENTLY REMARKABLE

The 2011 Radaris press release quoting their fake CEO Gary Norden said the company had four patents pending from a team of computer science PhDs. According to the resume shared by Mr. Gurvits, Dan Lubarsky has a PhD in computer science.

The U.S. Patent and Trademark Office (PTO) says Dan Lubarsky/Lubarski has at least nine technology patents to his name. The fake CEO press release from Radaris mentioning its four patents was published in April 2011. By that time, the PTO says Dan Lubarsky had applied for exactly four patents, including, “System and Method for a Web-Based People Directory.” The first of those patents, published in 2009, is tied to Humanbook.com, the company Dan Lubarsky founded that later changed its name to Radaris.

If the Lubarskys were never involved in Radaris, how do they or their attorney know the inside information that Gary Norden is a fiction of Radaris’ marketing department? KrebsOnSecurity has learned that Mr. Gurvits is the same attorney responding on behalf of Radaris in a lawsuit against the data broker filed earlier this year by Atlas Data Privacy.

Mr. Gurvits also stepped forward as Radaris’ attorney in a class action lawsuit the company lost in 2017 because it never contested the claim in court. When the plaintiffs told the judge they couldn’t collect on the $7.5 million default judgment, the judge ordered the domain registry Verisign to transfer the radaris.com domain name to the plaintiffs.

Mr. Gurvits appealed the verdict, arguing that the lawsuit hadn’t named the actual owners of the Radaris domain name — a Cyprus company called Bitseller Expert Limited — and thus taking the domain away would be a violation of their due process rights.

The judge ruled in Radaris’ favor — halting the domain transfer — and told the plaintiffs they could refile their complaint. Soon after, the operator of Radaris changed from Bitseller to Andtop Company, an entity formed (PDF) in the Marshall Islands in Oct. 2020. Andtop also operates the aforementioned people-search service Trustoria.

Mr. Gurvits’ most-publicized defamation case was a client named Aleksej Gubarev, a Russian technology executive whose name appeared in the Steele Dossier. That document included a collection of salacious, unverified information gathered by the former British intelligence officer Christopher Steele during the 2016 U.S. presidential campaign at the direction of former president Donald Trump’s political rivals.

Gubarev, the head of the IT services company XBT Holding and the Florida web hosting firm Webzilla, sued BuzzFeed for publishing the Steele dossier. One of the items in the dossier alleged that XBT/Webzilla and affiliated companies played a key role in the hack of Democratic Party computers in the spring of 2016. The memo alleged Gubarev had been coerced into providing services to Russia’s main domestic security agency, known as the FSB.

In December 2018, a federal judge in Miami ruled in favor of BuzzFeed, saying the publication was protected by the fair report privilege, which gives news organizations latitude in reporting on official government proceedings.

Radaris was originally operated by Bitseller Expert Limited. Who owns Bitseller Expert Limited? A report (PDF) obtained from the Cyprus business registry shows this company lists its director as Pavel Kaydash from Moscow. Mr. Kaydash could not be reached for comment.

Alleged Boss of ‘Scattered Spider’ Hacking Group Arrested

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

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

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

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

The cybercrime-focused Twitter/X account vx-underground said the U.K. man arrested was a SIM-swapper who went by the alias “Tyler.” In a SIM-swapping attack, crooks transfer the target’s phone number to a device they control and intercept any text messages or phone calls sent to the victim — including one-time passcodes for authentication, or password reset links sent via SMS.

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

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

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

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

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

0KTAPUS

In August 2022, KrebsOnSecurity wrote about peering inside the data harvested in a months-long cybercrime campaign by Scattered Spider involving countless SMS-based phishing attacks against employees at major corporations. The security firm Group-IB called the gang by a different name — 0ktapus, a nod to how the criminal group phished employees for credentials.

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

These phishing attacks used newly-registered domains that often included the name of the targeted company, and sent text messages urging employees to click on links to these domains to view information about a pending change in their work schedule. The phishing sites also featured a hidden Telegram instant message bot to forward any submitted credentials in real-time, allowing the attackers to use the phished username, password and one-time code to log in as that employee at the real employer website.

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

A Scattered Spider phishing lure sent to Twilio employees.

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

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

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

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

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

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

TURF WARS

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

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

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

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

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

How To Prevent Your Emails From Being Hacked

My mother recently turned 80, so of course a large celebration was in order. With 100 plus guests, entertainment, and catering to organise, the best way for me to keep everyone updated (and share tasks) was to use Google Docs. Gee, it worked well. My updates could immediately be seen by everyone, the family could access it from all the devices, and it was free to use! No wonder Google has a monopoly on drive and document sharing.

But here’s the thing – hackers know just how much both individuals and businesses have embraced Google products. So, it makes complete sense that they use reputable companies such as Google to devise phishing emails that are designed to extract our personal information. In fact, the Google Docs phishing scam was widely regarded as one of the most successful personal data extraction scams to date. They know that billions of people worldwide use Google so an invitation to click a link and view a document does not seem like an unreasonable email to receive. But it caused so much grief for so many people.

It’s All About Phishing

Emails designed to trick you into sharing your personal information are a scammer’s bread and butter. This is essentially what phishing is. It is by far the most successful tool they use to get their hands on your personal data and access your email.

‘But why do they want my email logins?’ – I hear you ask. Well, email accounts are what every scammer dreams of – they are a treasure trove of personally identifiable material that they can either steal or exploit. They could also use your email to launch a wide range of malicious activities from spamming and spoofing to spear phishing. Complicated terms, I know but in essence these are different types of phishing strategies. So, you can see why they are keen!!

But successful phishing emails usually share a few criteria which is important to know. Firstly, the email looks like it has been sent from a legitimate company e.g. Microsoft, Amex, or Google. Secondly, the email has a strong ‘call to action’ e.g. ‘your password has been changed, if this is not the case, please click here’. And thirdly, the email does not seem too out of place or random from the potential victim’s perspective.

What To Do To Prevent Your Email Being Hacked?

Despite the fact that scammers are savvy tricksters, there are steps you can take to maximise the chances your email remains locked away from their prying eyes. Here’s what I suggest:

  1. Don’t Fall Victim to a Phishing Scam

Never respond to an unexpected email or website that asks you for personal information or your login details no matter how professional it looks. If you have any doubts, always contact the company directly to verify.

  1. Protect Yourself!

Make sure you have super-duper internet security software that includes all the bells and whistles. Not only does internet security software McAfee+ include protection for daily browsing but it also has a password manager, a VPN, and a social privacy manager that will lock down your privacy settings on your social media accounts. A complete no-brainer!

  1. Say No to Public Wi-Fi and Public Computers

Avoid using public Wi-Fi to log into your email from public places. It takes very little effort for a hacker to position themselves between you and the connection point. So, it’s entirely possible for them to be in receipt of all your private information and logins which clearly you don’t want. If you really need to use it, invest in a Virtual Private Network (VPN) which will ensure everything you share via Wi-Fi will be encrypted. Your McAfee+ subscription includes a VPN.

Public computers should also be avoided even just to ‘check your email’. Not only is there a greater chance of spyware on untrusted computers but some of them sport key-logging programs which can both monitor and record the keys you strike on the keyboard – a great way of finding out your password!

  1. Passwords, Passwords, Passwords

Ensuring each of your online accounts has its own unique, strong, and complex password is one of the best ways of keeping hackers out of your life. I always suggest at least 10-12 characters with a combination of upper and lower case letters, symbols, and numbers. A crazy nonsensical sentence is a great option here but better still is a password manager that will remember and generate passwords that no human could! A password manager is also part of your McAfee+ online security pack.

What To Do If Your Email Is Hacked?

Even if you have taken all the necessary steps to protect your email from hackers, there is the chance that your email logins may be leaked in a data breach. A data breach happens when a company’s data is accessed by scammers and customers’ personal information is stolen. You may remember the Optus, Medibank and Latitude hacks of 2022/23?

If you have had your personal information stolen, please be assured that there are steps you can take to remedy this. The key is to act fast. Check out my recent blog post here for everything you need to know.

So, next time you’re organising a big gathering don’t hesitate to use Google Docs to plan or Microsoft Teams to host your planning meetings. While the thought of being hacked might make you want to withdraw, please don’t. Instead, cultivate a questioning mindset in both yourself and your kids, and always have a healthy amount of suspicion when going about your online life. You’ve got this!!

Till next time,
Stay safe!

The Verisign Shared Registration System: A 25-Year Retrospective

Blue abstract lines and dots on a dark blue gradient background.

Every day, there are tens of thousands of domain names registered across the globe – often as a key first step in creating a unique online presence. Making that experience possible for Verisign-operated top-level domains (TLDs) like .com and .net is a powerful and flexible technology platform first introduced 25 years ago.

Thanks to the Shared Registration System (SRS) – a hardware and software system conceptualized, designed, and launched by our teams 25 years ago – we’re able to successfully manage relationships with approximately 2,000 ICANN-accredited registrars who generally submit more than 100 million domain name transactions daily. Over the past quarter century, the SRS has thrived and grown with the global internet, in large part because we’ve continuously scaled and evolved the technology to meet exponentially increasing global demand, and a rapidly changing cyberthreat landscape.

In addition to enabling domain name registration, the usefulness of the technology extends beyond Verisign and its registry operations: many other companies subsequently adopted SRS concepts and implemented their own shared registration systems, making its impact far-reaching and long-lasting.

In this blog post, we commemorate the 25th anniversary of the launch of the Verisign SRS by reflecting on the insight and collaboration that went into developing a structure for domain name registration in those early days of the internet’s mainstream adoption.

When It All Began

Network Solutions, which Verisign acquired in 2000, had been functioning as both the sole registry and registrar for TLDs including .com, .net, and .org prior to 1999. The SRS was initially developed to make domain name registration more competitive and to encourage greater international participation, consistent with The Framework for Global Electronic Commerce, a directive to the U.S. Department of Commerce (DoC) to privatize the internet’s Domain Name System (DNS).

Work began in 1998 to develop and implement the SRS so that an unlimited number of registrars could provide domain name registration services, all under the administration of a common registry for each TLD. For several high-profile TLDs – including .com and .net – that registry was Network Solutions. That same year, the Internet Corporation for Assigned Names and Numbers (ICANN) – a multistakeholder not-for-profit organization dedicated to the management of key elements of the DNS – was formed.

Designing and Deploying the System

Over a period of several months, Network Solutions designed and installed the system, which was officially deployed on April 3, 1999. Through a testing period that ran through the second half of 1999, the number of test registrars grew from an initial five – AOL, CORE, France Telecom/Oleane, Melbourne IT, and Register.com – to more than 20 by the end of that year.

That same year, Network Solutions implemented modifications to the SRS so that a registrar could accept registrations and renewals in one-year increments, as well as enable a registrar to add one year to a registrant’s registration period when transferring a domain from one registrar to another. Once the SRS was live, it was made accessible to all ICANN-accredited registrars, providing each one with equivalent access to register domain names in the TLDs.

Moving Forward: The Extensible Provisioning Protocol

When the SRS was first launched, a simple protocol called the Registry-Registrar Protocol (RRP) was deployed to handle the registration and management of domain names by many registrars in one TLD. However, we recognized that the use of this protocol could only be temporary given the growth of the internet and the need for a registration system with increased scalability. Work on a more sophisticated registration system began almost immediately – in 1999 – and that came in the form of the Extensible Provisioning Protocol, or EPP. EPP officially became an Internet Standard in 2009.

Today, EPP is used to register domain names and perform domain name-related functions, and there are over 2,000 ICANN-accredited registrars that all use EPP. EPP is central to the way that Verisign and many other authoritative registry operators do business: these registry operators work with domain name registrars to register domain names, and the registrars in turn offer a diverse range of domain name products to end users. Indeed, the simplicity of registering domains through EPP, and, for TLDs operated by Verisign, through the SRS, not only opened the door to easy access to domain name registration services, but also paved the way for new digital commerce and communications capabilities.

Powering Registrations in the Past, Present, and Future

For the past 25 years, the SRS has been a critical component of the internet’s backend technology, even though it’s not widely known outside the DNS community. Thanks to the foresight and planning of many talented technologists, we built and evolved this system in such a way that it has successfully supported hundreds of millions of domain name registrations across the globe, serving as a first step for many on the path to establishing durable online identities. Along the way, we’ve added support for new technologies, including DNSSEC and Internationalized Domain Names (IDNs). We’ve made the system more secure by strengthening the domain name locking and transfer processes. We’ve also expanded the SRS to support additional TLDs administered by Verisign. In its own quiet way, the SRS has helped to support the dynamic growth of the internet, while prioritizing equivalent access to domain name registration.

Many of the people who worked on the launch of the SRS are still with Verisign today, myself included. We are fortunate to have the chance to continue working together – 25 years later – always with an eye toward the future and how we can continue to help the internet grow and prosper.

Stark Industries Solutions: An Iron Hammer in the Cloud

The homepage of Stark Industries Solutions.

Two weeks before Russia invaded Ukraine in February 2022, a large, mysterious new Internet hosting firm called Stark Industries Solutions materialized and quickly became the epicenter of massive distributed denial-of-service (DDoS) attacks on government and commercial targets in Ukraine and Europe. An investigation into Stark Industries reveals it is being used as a global proxy network that conceals the true source of cyberattacks and disinformation campaigns against enemies of Russia.

At least a dozen patriotic Russian hacking groups have been launching DDoS attacks since the start of the war at a variety of targets seen as opposed to Moscow. But by all accounts, few attacks from those gangs have come close to the amount of firepower wielded by a pro-Russia group calling itself “NoName057(16).”

This graphic comes from a recent report from NETSCOUT about DDoS attacks from Russian hacktivist groups.

As detailed by researchers at Radware, NoName has effectively gamified DDoS attacks, recruiting hacktivists via its Telegram channel and offering to pay people who agree to install a piece of software called DDoSia. That program allows NoName to commandeer the host computers and their Internet connections in coordinated DDoS campaigns, and DDoSia users with the most attacks can win cash prizes.

A report from the security firm Team Cymru found the DDoS attack infrastructure used in NoName campaigns is assigned to two interlinked hosting providers: MIRhosting and Stark Industries. MIRhosting is a hosting provider founded in The Netherlands in 2004. But Stark Industries Solutions Ltd was incorporated on February 10, 2022, just two weeks before the Russian invasion of Ukraine.

PROXY WARS

Security experts say that not long after the war started, Stark began hosting dozens of proxy services and free virtual private networking (VPN) services, which are designed to help users shield their Internet usage and location from prying eyes.

Proxy providers allow users to route their Internet and Web browsing traffic through someone else’s computer. From a website’s perspective, the traffic from a proxy network user appears to originate from the rented 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 also massively abused for hiding cybercrime activity because they can make it difficult to trace malicious traffic to its original source.

What’s more, many proxy services do not disclose how they obtain access to the proxies they are renting out, and in many cases the access is obtained through the dissemination of malicious software that turns the infected system into a traffic relay — usually unbeknownst to the legitimate owner of the Internet connection. Other proxy services will allow users to make money by renting out their Internet connection to anyone.

Spur.us is a company that tracks VPNs and proxy services worldwide. Spur finds that Stark Industries (AS44477) currently is home to at least 74 VPN services, and 40 different proxy services. As we’ll see in the final section of this story, just one of those proxy networks has over a million Internet addresses available for rent across the globe.

Raymond Dijkxhoorn operates a hosting firm in The Netherlands called Prolocation. He also co-runs SURBL, an anti-abuse service that flags domains and Internet address ranges that are strongly associated with spam and cybercrime activity, including DDoS.

Dijkxhoorn said last year SURBL heard from multiple people who said they operated VPN services whose web resources were included in SURBL’s block lists.

“We had people doing delistings at SURBL for domain names that were suspended by the registrars,” Dijkhoorn told KrebsOnSecurity. “And at least two of them explained that Stark offered them free VPN services that they were reselling.”

Dijkxhoorn added that Stark Industries also sponsored activist groups from Ukraine.

“How valuable would it be for Russia to know the real IPs from Ukraine’s tech warriors?” he observed.

CLOUDY WITH A CHANCE OF BULLETS

Richard Hummel is threat intelligence lead at NETSCOUT. Hummel said when he considers the worst of all the hosting providers out there today, Stark Industries is consistently near or at the top of that list.

“The reason is we’ve had at least a dozen service providers come to us saying, ‘There’s this network out there inundating us with traffic,'” Hummel said. “And it wasn’t even DDoS attacks. [The systems] on Stark were just scanning these providers so fast it was crashing some of their services.”

Hummel said NoName will typically launch their attacks using a mix of resources rented from major, legitimate cloud services, and those from so-called “bulletproof” hosting providers like Stark. Bulletproof providers are so named when they earn or cultivate a reputation for ignoring any abuse complaints or police reports about activity on their networks.

Combining bulletproof providers with legitimate cloud hosting, Hummel said, likely makes NoName’s DDoS campaigns more resilient because many network operators will hesitate to be too aggressive in blocking Internet addresses associated with the major cloud services.

“What we typically see here is a distribution of cloud hosting providers and bulletproof hosting providers in DDoS attacks,” he said. “They’re using public cloud hosting providers because a lot of times that’s your first layer of network defense, and because [many companies are wary of] over-blocking access to legitimate cloud resources.”

But even if the cloud provider detects abuse coming from the customer, the provider is probably not going to shut the customer down immediately, Hummel said.

“There is usually a grace period, and even if that’s only an hour or two, you can still launch a large number of attacks in that time,” he said. “And then they just keep coming back and opening new cloud accounts.”

MERCENARIES TEAM

Stark Industries is incorporated at a mail drop address in the United Kingdom. UK business records list an Ivan Vladimirovich Neculiti as the company’s secretary. Mr. Neculiti also is named as the CEO and founder of PQ Hosting Plus S.R.L. (aka Perfect Quality Hosting), a Moldovan company formed in 2019 that lists the same UK mail drop address as Stark Industries.

Ivan Neculiti, as pictured on LinkedIn.

Reached via LinkedIn, Mr. Neculiti said PQ Hosting established Stark Industries as a “white label” of its brand so that “resellers could distribute our services using our IP addresses and their clients would not have any affairs with PQ Hosting.”

“PQ Hosting is a company with over 1,000+ of [our] own physical servers in 38 countries and we have over 100,000 clients,” he said. “Though we are not as large as Hetzner, Amazon and OVH, nevertheless we are a fast growing company that provides services to tens of thousands of private customers and legal entities.”

Asked about the constant stream of DDoS attacks whose origins have traced back to Stark Industries over the past two years, Neculiti maintained Stark hasn’t received any official abuse reports about attacks coming from its networks.

“It was probably some kind of clever attack that we did not see, I do not rule out this fact, because we have a very large number of clients and our Internet channels are quite large,” he said. “But, in this situation, unfortunately, no one contacted us to report that there was an attack from our addresses; if someone had contacted us, we would have definitely blocked the network data.”

DomainTools.com finds Ivan V. Neculiti was the owner of war[.]md, a website launched in 2008 that chronicled the history of a 1990 armed conflict in Moldova known as the Transnistria War and the Moldo-Russian war.

An ad for war.md, circa 2009.

Transnistria is a breakaway pro-Russian region that declared itself a state in 1990, although it is not internationally recognized. The copyright on that website credits the “MercenarieS TeaM,” which was at one time a Moldovan IT firm. Mr. Neculiti confirmed personally registering this domain.

DON CHICHO & DFYZ

The data breach tracking service Constella Intelligence reports that an Ivan V. Neculiti registered multiple online accounts under the email address dfyz_bk@bk.ru. Cyber intelligence firm Intel 471 shows this email address is tied to the username “dfyz” on more than a half-dozen Russian language cybercrime forums since 2008. The user dfyz on Searchengines[.]ru in 2008 asked other forum members to review war.md, and said they were part of the MercenarieS TeaM.

Back then, dfyz was selling “bulletproof servers for any purpose,” meaning the hosting company would willfully ignore abuse complaints or police inquiries about the activity of its customers.

DomainTools reports there are at least 33 domain names registered to dfyz_bk@bk.ru. Several of these domains have Ivan Neculiti in their registration records, including tracker-free[.]cn, which was registered to an Ivan Neculiti at dfyz_bk@bk.ru and referenced the MercenarieS TeaM in its original registration records.

Dfyz also used the nickname DonChicho, who likewise sold bulletproof hosting services and access to hacked Internet servers. In 2014, a prominent member of the Russian language cybercrime community Antichat filed a complaint against DonChicho, saying this user scammed them and had used the email address dfyz_bk@bk.ru.

The complaint said DonChicho registered on Antichat from the Transnistria Internet address 84.234.55[.]29. Searching this address in Constella reveals it has been used to register just five accounts online that have been created over the years, including one at ask.ru, where the user registered with the email address neculitzy1@yandex.ru. Constella also returns for that email address a user by the name “Ivan” at memoraleak.com and 000webhost.com.

Constella finds that the password most frequently used by the email address dfyz_bk@bk.ru was “filecast,” and that there are more than 90 email addresses associated with this password. Among them are roughly two dozen addresses with the name “Neculiti” in them, as well as the address support@donservers[.]ru.

Intel 471 says DonChicho posted to several Russian cybercrime forums that support@donservers[.]ru was his address, and that he logged into cybercrime forums almost exclusively from Internet addresses in Tiraspol, the capital of Transnistria. A review of DonChicho’s posts shows this person was banned from several forums in 2014 for scamming other users.

Cached copies of DonChicho’s vanity domain (donchicho[.]ru) show that in 2009 he was a spammer who peddled knockoff prescription drugs via Rx-Promotion, once one of the largest pharmacy spam moneymaking programs for Russian-speaking affiliates.

Mr. Neculiti told KrebsOnSecurity he has never used the nickname DonChicho.

“I may assure you that I have no relation to DonChicho nor to his bulletproof servers,” he said.

Below is a mind map that shows the connections between the accounts mentioned above.

A mind map tracing the history of the user Dfyz. Click to enlarge.

Earlier this year, NoName began massively hitting government and industry websites in Moldova. A new report from Arbor Networks says the attacks began around March 6, when NoName alleged the government of Moldova was “craving for Russophobia.”

“Since early March, more than 50 websites have been targeted, according to posted ‘proof’ by the groups involved in attacking the country,” Arbor’s ASERT Team wrote. “While NoName seemingly initiated the ramp of attacks, a host of other DDoS hacktivists have joined the fray in claiming credit for attacks across more than 15 industries.”

CORRECTIV ACTION

The German independent news outlet Correctiv.org last week published a scathing investigative report on Stark Industries and MIRhosting, which notes that Ivan Neculiti operates his hosting companies with the help of his brother, Yuri.

Image credit: correctiv.org.

The report points out that Stark Industries continues to host a Russian disinformation news outlet called “Recent Reliable News” (RRN) that was sanctioned by the European Union in 2023 for spreading links to propaganda blogs and fake European media and government websites.

“The website was not running on computers in Moscow or St. Petersburg until recently, but in the middle of the EU, in the Netherlands, on the computers of the Neculiti brothers,” Correctiv reporters wrote.

“After a request from this editorial team, a well-known service was installed that hides the actual web host,” the report continues. “Ivan Neculiti announced that he had blocked the associated access and server following internal investigations. “We very much regret that we are only now finding out that one of our customers is a sanctioned portal,” said the company boss. However, RRN is still accessible via its servers.”

Correctiv also points to a January 2023 report from the Ukrainian government, which found servers from Stark Industries Solutions were used as part of a cyber attack on the Ukrainian news agency “Ukrinform”. Correctiv notes the notorious hacker group Sandworm — an advanced persistent threat (APT) group operated by a cyberwarfare unit of Russia’s military intelligence service — was identified by Ukrainian government authorities as responsible for that attack.

PEACE HOSTING?

Public records indicate MIRhosting is based in The Netherlands and is operated by 37-year old Andrey Nesterenko, whose personal website says he is an accomplished concert pianist who began performing publicly at a young age.

DomainTools says mirhosting[.]com is registered to Mr. Nesterenko and to Innovation IT Solutions Corp, which lists addresses in London and in Nesterenko’s stated hometown of Nizhny Novgorod, Russia.

This is interesting because according to the book Inside Cyber Warfare by Jeffrey Carr, Innovation IT Solutions Corp. was responsible for hosting StopGeorgia[.]ru, a hacktivist website for organizing cyberattacks against Georgia that appeared at the same time Russian forces invaded the former Soviet nation in 2008. That conflict was thought to be the first war ever fought in which a notable cyberattack and an actual military engagement happened simultaneously.

Responding to questions from KrebsOnSecurity, Mr. Nesterenko said he couldn’t say whether his network had ever hosted the StopGeorgia website back in 2008 because his company didn’t keep records going back that far. But he said Stark Industries Solutions is indeed one of MIRhsoting’s colocation customers.

“Our relationship is purely provider-customer,” Nesterenko said. “They also utilize multiple providers and data centers globally, so connecting them directly to MIRhosting overlooks their broader network.”

“We take any report of malicious activity seriously and are always open to information that can help us identify and prevent misuse of our infrastructure, whether involving Stark Industries or any other customer,” Nesterenko continued. “In cases where our services are exploited for malicious purposes, we collaborate fully with Dutch cyber police and other relevant authorities to investigate and take appropriate measures. However, we have yet to receive any actionable information beyond the article itself, which has not provided us with sufficient detail to identify or block malicious actors.”

In December 2022, security firm Recorded Future profiled the phishing and credential harvesting infrastructure used for Russia-aligned espionage operations by a group dubbed Blue Charlie (aka TAG-53), which has targeted email accounts of nongovernmental organizations and think tanks, journalists, and government and defense officials.

Recorded Future found that virtually all the Blue Charlie domains existed in just ten different ISPs, with a significant concentration located in two networks, one of which was MIRhosting. Both Microsoft and the UK government assess that Blue Charlie is linked to the Russian threat activity groups variously known as Callisto Group, COLDRIVER, and SEABORGIUM.

Mr. Nesterenko took exception to a story on that report from The Record, which is owned by Recorded Future.

“We’ve discussed its contents with our customer, Stark Industries,” he said. “We understand that they have initiated legal proceedings against the website in question, as they firmly believe that the claims made are inaccurate.”

Recorded Future said they updated their story with comments from Mr. Neculiti, but that they stand by their reporting.

Mr. Nesterenko’s LinkedIn profile says he was previously the foreign region sales manager at Serverius-as, a hosting company in The Netherlands that remains in the same data center as MIRhosting.

In February, the Dutch police took 13 servers offline that were used by the infamous LockBit ransomware group, which had originally bragged on its darknet website that its home base was in The Netherlands. Sources tell KrebsOnSecurity the servers seized by the Dutch police were located in Serverius’ data center in Dronten, which is also shared by MIRhosting.

Serverius-as did not respond to requests for comment. Nesterenko said MIRhosting does use one of Serverius’s data centers for its operations in the Netherlands, alongside two other data centers, but that the recent incident involving the seizure of servers has no connection to MIRhosting.

“We are legally prohibited by Dutch law and police regulations from sharing information with third parties regarding any communications we may have had,” he said.

A February 2024 report from security firm ESET found Serverius-as systems were involved in a series of targeted phishing attacks by Russia-aligned groups against Ukrainian entities throughout 2023. ESET observed that after the spearphishing domains were no longer active, they were converted to promoting rogue Internet pharmacy websites.

PEERING INTO THE VOID

A review of the Internet address ranges recently added to the network operated by Stark Industries Solutions offers some insight into its customer base, usage, and maybe even true origins. Here is a snapshot (PDF) of all Internet address ranges announced by Stark Industries so far in the month of May 2024 (this information was graciously collated by the network observability platform Kentik.com).

Those records indicate that the largest portion of the IP space used by Stark is in The Netherlands, followed by Germany and the United States. Stark says it is connected to roughly 4,600 Internet addresses that currently list their ownership as Comcast Cable Communications.

A review of those address ranges at spur.us shows all of them are connected to an entity called Proxyline, which is a sprawling proxy service based in Russia that currently says it has more than 1.6 million proxies globally that are available for rent.

Reached for comment, Comcast said the Internet address ranges never did belong to Comcast, so it is likely that Stark has been fudging the real location of its routing announcements in some cases.

Stark reports that it has more than 67,000 Internet addresses at Santa Clara, Calif.-based EGIhosting. Spur says the Stark addresses involving EGIhosting all map to Proxyline as well. EGIhosting did not respond to requests for comment.

EGIhosting manages Internet addresses for the Cyprus-based hosting firm ITHOSTLINE LTD (aka HOSTLINE-LTD), which is represented throughout Stark’s announced Internet ranges. Stark says it has more than 21,000 Internet addresses with HOSTLINE. Spur.us finds Proxyline addresses are especially concentrated in the Stark ranges labeled ITHOSTLINE LTD, HOSTLINE-LTD, and Proline IT.

Stark’s network list includes approximately 21,000 Internet addresses at Hockessin, De. based DediPath, which abruptly ceased operations without warning in August 2023. According to a phishing report released last year by Interisle Consulting, DediPath was the fourth most common source of phishing attacks in the year ending Oct. 2022. Spur.us likewise finds that virtually all of the Stark address ranges marked “DediPath LLC” are tied to Proxyline.

A large number of the Internet address ranges announced by Stark in May originate in India, and the names that are self-assigned to many of these networks indicate they were previously used to send large volumes of spam for herbal medicinal products, with names like HerbalFarm, AdsChrome, Nutravo, Herbzoot and Herbalve.

The anti-spam organization SpamHaus reports that many of the Indian IP address ranges are associated with known “snowshoe spam,” a form of abuse that involves mass email campaigns spread across several domains and IP addresses to weaken reputation metrics and avoid spam filters.

It’s not clear how much of Stark’s network address space traces its origins to Russia, but big chunks of it recently belonged to some of the oldest entities on the Russian Internet (a.k.a. “Runet”).

For example, many Stark address ranges were most recently assigned to a Russian government entity whose full name is the “Federal State Autonomous Educational Establishment of Additional Professional Education Center of Realization of State Educational Policy and Informational Technologies.”

A review of Internet address ranges adjacent to this entity reveals a long list of Russian government organizations that are part of the Federal Guard Service of the Russian Federation. Wikipedia says the Federal Guard Service is a Russian federal government agency concerned with tasks related to protection of several high-ranking state officials, including the President of Russia, as well as certain federal properties. The agency traces its origins to the USSR’s Ninth Directorate of the KGB, and later the presidential security service.

Stark recently announced the address range 213.159.64.0/20 from April 27 to May 1, and this range was previously assigned to an ancient ISP in St. Petersburg, RU called the Computer Technologies Institute Ltd.

According to a post on the Russian language webmaster forum searchengines[.]ru, the domain for Computer Technologies Institute — ctinet[.]ruis the seventh-oldest domain in the entire history of the Runet.

Curiously, Stark also lists large tracts of Internet addresses (close to 48,000 in total) assigned to a small ISP in Kharkiv, Ukraine called NetAssist. Reached via email, the CEO of NetAssist Max Tulyev confirmed his company provides a number of services to PQ Hosting.

“We colocate their equipment in Warsaw, Madrid, Sofia and Thessaloniki, provide them IP transit and IPv4 addresses,” Tulyev said. “For their size, we receive relatively low number of complains to their networks. I never seen anything about their pro-Russian activity or support of Russian hackers. It is very interesting for me to see proofs of your accusations.”

Spur.us mapped the entire infrastructure of Proxyline, and found more than one million proxies across multiple providers, but by far the biggest concentration was at Stark Industries Solutions. The full list of Proxyline address ranges (.CSV) shows two other ISPs appear repeatedly throughout the list. One is Kharkiv, Ukraine based ITL LLC, also known as Information Technology Laboratories Group, and Integrated Technologies Laboratory.

The second is a related hosting company in Miami, called Green Floid LLC. Green Floid featured in a 2017 scoop by CNN, which profiled the company’s owner and quizzed him about Russian troll farms using proxy networks on Green Floid and its parent firm ITL to mask disinformation efforts tied to the Kremlin’s Internet Research Agency (IRA). At the time, the IRA was using Facebook and other social media networks to spread videos showing police brutality against African Americans in an effort to encourage protests across the United States.

Doug Madory, director of Internet analysis at Kentik, was able to see at a high level the top sources and destinations for traffic traversing Stark’s network.

“Based on our aggregate NetFlow, we see Iran as the top destination (35.1%) for traffic emanating from Stark (AS44477),” Madory said. “Specifically, the top destination is MTN Irancell, while the top source is Facebook. This data supports the theory that AS44477 houses proxy services as Facebook is blocked in Iran.”

On April 30, the security firm Malwarebytes explored an extensive malware operation that targets corporate Internet users with malicious ads. Among the sites used as lures in that campaign were fake Wall Street Journal and CNN websites that told visitors they were required to install a WSJ or CNN-branded browser extension (malware). Malwarebytes found a domain name central to that operation was hosted at Internet addresses owned by Stark Industries.

Ivanti Patches Critical Remote Code Execution Flaws in Endpoint Manager

Ivanti on Tuesday rolled out fixes to address multiple critical security flaws in Endpoint Manager (EPM) that could be exploited to achieve remote code execution under certain circumstances. Six of the 10 vulnerabilities – from CVE-2024-29822 through CVE-2024-29827 (CVSS scores: 9.6) – relate to SQL injection flaws that allow an unauthenticated attacker within the same network to

What to Do If Your Email Is Hacked

I think I could count on my hand the people I know who have NOT had their email hacked. Maybe they found a four-leaf clover when they were kids!

Email hacking is one of the very unfortunate downsides of living in our connected, digital world. And it usually occurs as a result of a data breach – a situation that even the savviest tech experts find themselves in.

What Is A Data Breach?

In simple terms, a data breach happens when personal information is accessed, disclosed without permission, or lost. Companies, organisations, and government departments of any size can be affected. Data stolen can include customer login details (email addresses and passwords), credit card numbers, identifying IDs of customers e.g. driver’s license numbers and/or passport numbers, confidential customer information, company strategy, or even matters of national security.

Data breaches have made headlines, particularly over the last few years. When the Optus and Medibank data breaches hit the news in 2022 affecting almost 10 million Aussies a piece, we were all shaken. But then when Aussie finance company Latitude, was affected in 2023 with a whopping 14 million people from both Australia and New Zealand affected, it almost felt inevitable that by now, most of us would have been impacted.

But these were the data breaches that grabbed our attention. The reality is that data breaches have been happening for years. In fact, the largest data breach in Australian history actually happened in May 2019 to the online design site Canva which affected 137 million users globally including many Aussies.

So, in short – it can happen to anyone, and the chances are you may have already been affected.

But Why Should I Worry? I Have Nothing Valuable in My Email

The sole objective of a hacker is to get their hands on your data. And any information that you share in your email account can be very valuable to them. But why do they want your data, you ask? It’s simple really – so they can cash in! Some will keep the juicy stuff for themselves – passwords or logins to government departments or large companies they may want to ’target’ with the aim of extracting valuable data and/or funds. But the more sophisticated ones will sell your details including name, telephone, email address, and credit card details, and cash in on the Dark Web. They often do this in batches. Some experts believe they can get as much as AU$250 for a full set of details including credit cards. So, you can see why they’d be interested in you!

The other reason why hackers will be interested in your email address and password is that many of us re-use these login details across our other online accounts too. So, once they’ve got their hands on your email credentials then they may be able to access your online banking and investment accounts – the possibilities are endless if you are using the same login credentials everywhere. So, you can see why I harp on about using a unique password for every online account!

How Big Is the Problem?

There is a plethora of statistics on just how big this issue is – all of them concerning.

According to the Australian Institute of Criminology, there were over 16,000 reports of identity theft in 2022.

The Department of Home Affairs and Stay Smart Australia reports that cybercrime costs Australian businesses $29 billion a year with the average business spending around $275,000 to remedy a data breach

And although there has been a slight reduction in Aussies falling for phishing scams in recent years (down from 2.7% in 2020/1 to 2.5% in 2022/3), more Australians are falling victim to card fraud scams with a total of $2.2 billion lost in 2023.

But regardless of which statistic you choose to focus on, we have a big issue on our hands!

So, What Do I Do If My Email Is Hacked?

If you find yourself a victim of email hacking there are a few very important steps you need to take and the key is to take them FAST!!

  1. Change Your Password

This is the very first thing you must do to ensure the hacker can’t get back into your account. It is essential that your new password is complex and totally unrelated to previous passwords. Always use at least 8-10 characters with a variety of upper and lower case and throw in some symbols and numbers. I really like the idea of a crazy, nonsensical sentence – easier to remember and harder to crack! But, better still, get yourself a password manager that will create a password that no human would be capable of creating.

If you find the hacker has locked you out of your account by changing your password, you will need to reset the password by clicking on the ‘Forgot My Password’ link.

  1. Change Any Other Accounts with the Same Password

This is time-consuming but essential. Ensure you change any other accounts that use the same username and password as your compromised email. Hackers love the fact that many people still use the same logins for multiple accounts, so it is guaranteed they will try your info in other email applications and sites such as PayPal, Amazon, Netflix – you name it!

Once the dust has settled, please review your password strategy for all your online accounts. A best practice is to ensure every online account has its own unique and complex password.

  1. Let Your Email Contacts Know

A big part of the hacker’s strategy is to ‘get their claws’ into your address book with the aim of hooking others as well. Send a message to all your email contacts as soon as possible so they know to avoid opening any emails (most likely loaded with malware) that have come from you.

  1. Commit to Multi-factor Authentication

Yes, multi-factor authentication (or 2-factor authentication) adds another step to your login but it also adds another layer of protection. Enabling this will mean that in addition to your password, you will need a special one-time use code to log in. This can be sent to your mobile phone or alternatively, it may be generated via an authenticator app. So worthwhile!

  1. Check Your Email Settings

It is not uncommon for hackers to modify your email settings so that a copy of every email you receive is automatically forwarded to them. Not only can they monitor your logins for other sites, but they’ll keep a watchful eye over any particularly juicy personal information. So, check your mail forwarding settings to ensure no unexpected email addresses have been added.

Don’t forget to check your email signature to ensure nothing spammy has been added. Also, ensure your ‘reply to’ email address is actually yours! Hackers have been known to create an email address here that looks similar to yours – when someone replies, it goes straight to their account, not yours!

  1. Scan Your Computer for Malware and Viruses

This is essential also. If you find anything, please ensure it is addressed, and then change your email password again. And if you don’t have it – please invest. Comprehensive security software will provide you with a digital shield for your online life. McAfee+ lets you protect all your devices – including your smartphone – from viruses and malware. It also contains a password manager to help you remember and generate unique passwords for all your accounts.

  1. Consider Creating a New Email Address

If you have been hacked several times and your email provider isn’t mitigating the amount of spam you are receiving, then consider starting afresh but don’t delete your email address. Many experts warn against deleting email accounts as most email providers will recycle your old email address. This could mean a hacker could spam every site they can find with a ‘forgot my password’ request and try to impersonate you – identity theft!

Your email is an important part of your online identity so being vigilant and addressing any fallout from hacking is essential for your digital reputation. And even though it may feel that ‘getting hacked’ is inevitable, you can definitely reduce your risk by installing some good quality security software on all your devices. Comprehensive security software such as McAfee+ will alert you when visiting risky websites, warn you when a download looks ‘dodgy’, and will block annoying and dangerous emails with anti-spam technology.

It makes sense really – if you don’t receive the ‘dodgy’ phishing email – you can’t click on it! Smart!

And finally, don’t forget that hackers love social media – particularly those of us who overshare on it. So, before you post details of your adorable new kitten, remember it may just provide the perfect clue for a hacker trying to guess your email password!

Till next time

Alex

Dutch Court Sentences Tornado Cash Co-Founder to 5 Years in Prison for Money Laundering

A Dutch court on Tuesday sentenced one of the co-founders of the now-sanctioned Tornado Cash cryptocurrency mixer service to 5 years and 4 months in prison. While the name of the defendant was redacted in the verdict, it's known that Alexey Pertsev, a 31-year-old Russian national, had been awaiting trial in the Netherlands on money laundering charges.

Patch Tuesday, May 2024 Edition

Microsoft today released updates to fix more than 60 security holes in Windows computers and supported software, including two “zero-day” vulnerabilities in Windows that are already being exploited in active attacks. There are also important security patches available for macOS and Adobe users, and for the Chrome Web browser, which just patched its own zero-day flaw.

First, the zero-days. CVE-2024-30051 is an “elevation of privilege” bug in a core Windows library. Satnam Narang at Tenable said this flaw is being used as part of post-compromise activity to elevate privileges as a local attacker.

“CVE-2024-30051 is used to gain initial access into a target environment and requires the use of social engineering tactics via email, social media or instant messaging to convince a target to open a specially crafted document file,” Narang said. “Once exploited, the attacker can bypass OLE mitigations in Microsoft 365 and Microsoft Office, which are security features designed to protect end users from malicious files.”

Kaspersky Lab, one of two companies credited with reporting exploitation of CVE-2024-30051 to Microsoft, has published a fascinating writeup on how they discovered the exploit in a file shared with Virustotal.com.

Kaspersky said it has since seen the exploit used together with QakBot and other malware. Emerging in 2007 as a banking trojan, QakBot (a.k.a. Qbot and Pinkslipbot) has morphed into an advanced malware strain now used by multiple cybercriminal groups to prepare newly compromised networks for ransomware infestations.

CVE-2024-30040 is a security feature bypass in MSHTML, a component that is deeply tied to the default Web browser on Windows systems. Microsoft’s advisory on this flaw is fairly sparse, but Kevin Breen from Immersive Labs said this vulnerability also affects Office 365 and Microsoft Office applications.

“Very little information is provided and the short description is painfully obtuse,” Breen said of Microsoft’s advisory on CVE-2024-30040.

The only vulnerability fixed this month that earned Microsoft’s most-dire “critical” rating is CVE-2024-30044, a flaw in Sharepoint that Microsoft said is likely to be exploited. Tenable’s Narang notes that exploitation of this bug requires an attacker to be authenticated to a vulnerable SharePoint Server with Site Owner permissions (or higher) first and to take additional steps in order to exploit this flaw, which makes this flaw less likely to be widely exploited as most attackers follow the path of least resistance.

Five days ago, Google released a security update for Chrome that fixes a zero-day in the popular browser. Chrome usually auto-downloads any available updates, but it still may require a complete restart of the browser to install them. If you use Chrome and see a “Relaunch to update” message in the upper right corner of the browser, it’s time to restart.

Apple has just shipped macOS Sonoma 14.5 update, which includes nearly two dozen security patches. To ensure your Mac is up-to-date, go to System Settings, General tab, then Software Update and follow any prompts.

Finally, Adobe has critical security patches available for a range of products, including Acrobat, Reader, Illustrator, Adobe Substance 3D Painter, Adobe Aero, Adobe Animate and Adobe Framemaker.

Regardless of whether you use a Mac or Windows system (or something else), it’s always a good idea to backup your data and or system before applying any security updates. For a closer look at the individual fixes released by Microsoft today, check out the complete list over at the SANS Internet Storm Center. Anyone in charge of maintaining Windows systems in an enterprise environment should keep an eye on askwoody.com, which usually has the scoop on any wonky Windows patches.

Update, May 15, 8:28 a.m.: Corrected misattribution of CVE-2024-30051.

The $2.3 Billion Tornado Cash Case Is a Pivotal Moment for Crypto Privacy

Tuesday’s verdict in the trial of Alexey Pertsev, a creator of crypto-privacy service Tornado Cash, is the first in a string of cases that could make it much harder to skirt financial surveillance.

How Did Authorities Identify the Alleged Lockbit Boss?

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

Dmitry Yuryevich Khoroshev. Image: treasury.gov.

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

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

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

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

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

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

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

Image: Shutterstock.

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

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

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

NEROWOLFE

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

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

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

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

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

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

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

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

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

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

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

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

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

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

PUTINKRAB

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

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

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

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

A machine-translated ad for ransomware source code from Putinkrab on the Russian language cybercrime forum UFOlabs in 2019. Image: Ke-la.com.

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

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

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

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

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

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

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

The rest of his response was structured like a poem:

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

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

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

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

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

CONCLUSION

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

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

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

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

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

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

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

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

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

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

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

U.S. Charges Russian Man as Boss of LockBit Ransomware Group

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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