The FBI joined authorities across Europe last week in seizing domain names for Cracked and Nulled, English-language cybercrime forums with millions of users that trafficked in stolen data, hacking tools and malware. An investigation into the history of these communities shows their apparent co-founders quite openly operate an Internet service provider and a pair of e-commerce platforms catering to buyers and sellers on both forums.
In this 2019 post from Cracked, a forum moderator told the author of the post (Buddie) that the owner of the RDP service was the founder of Nulled, a.k.a. “Finndev.” Image: Ke-la.com.
On Jan. 30, the U.S. Department of Justice said it seized eight domain names that were used to operate Cracked, a cybercrime forum that sprang up in 2018 and attracted more than four million users. The DOJ said the law enforcement action, dubbed Operation Talent, also seized domains tied to Sellix, Cracked’s payment processor.
In addition, the government seized the domain names for two popular anonymity services that were heavily advertised on Cracked and Nulled and allowed customers to rent virtual servers: StarkRDP[.]io, and rdp[.]sh.
Those archived webpages show both RDP services were owned by an entity called 1337 Services Gmbh. According to corporate records compiled by Northdata.com, 1337 Services GmbH is also known as AS210558 and is incorporated in Hamburg, Germany.
The Cracked forum administrator went by the nicknames “FlorainN” and “StarkRDP” on multiple cybercrime forums. Meanwhile, a LinkedIn profile for a Florian M. from Germany refers to this person as the co-founder of Sellix and founder of 1337 Services GmbH.
Northdata’s business profile for 1337 Services GmbH shows the company is controlled by two individuals: 32-year-old Florian Marzahl and Finn Alexander Grimpe, 28.

Neither Marzahl nor Grimpe responded to requests for comment. But Grimpe’s first name is interesting because it corresponds to the nickname chosen by the founder of Nulled, who goes by the monikers “Finn” and “Finndev.” NorthData reveals that Grimpe was the founder of a German entity called DreamDrive GmbH, which rented out high-end sports cars and motorcycles.
According to the cyber intelligence firm Intel 471, a user named Finndev registered on multiple cybercrime forums, including Raidforums [seized by the FBI in 2022], Void[.]to, and vDOS, a DDoS-for-hire service that was shut down in 2016 after its founders were arrested.
The email address used for those accounts was f.grimpe@gmail.com. DomainTools.com reports f.grimpe@gmail.com was used to register at least nine domain names, including nulled[.]lol and nulled[.]it. Neither of these domains were among those seized in Operation Talent.
Intel471 finds the user FlorainN registered across multiple cybercrime forums using the email address olivia.messla@outlook.de. The breach tracking service Constella Intelligence says this email address used the same password (and slight variations of it) across many accounts online — including at hacker forums — and that the same password was used in connection with dozens of other email addresses, such as florianmarzahl@hotmail.de, and fmarzahl137@gmail.com.
The Justice Department said the Nulled marketplace had more than five million members, and has been selling stolen login credentials, stolen identification documents and hacking services, as well as tools for carrying out cybercrime and fraud, since 2016.
Perhaps fittingly, both Cracked and Nulled have been hacked over the years, exposing countless private messages between forum users. A review of those messages archived by Intel 471 showed that dozens of early forum members referred privately to Finndev as the owner of shoppy[.]gg, an e-commerce platform that caters to the same clientele as Sellix.
Shoppy was not targeted as part of Operation Talent, and its website remains online. Northdata reports that Shoppy’s business name — Shoppy Ecommerce Ltd. — is registered at an address in Gan-Ner, Israel, but there is no ownership information about this entity. Shoppy did not respond to requests for comment.
Constella found that a user named Shoppy registered on Cracked in 2019 using the email address finn@shoppy[.]gg. Constella says that email address is tied to a Twitter/X account for Shoppy Ecommerce in Israel.
The DOJ said one of the alleged administrators of Nulled, a 29-year-old Argentinian national named Lucas Sohn, was arrested in Spain. The government has not announced any other arrests or charges associated with Operation Talent.
Indeed, both StarkRDP and FloraiN have posted to their accounts on Telegram that there were no charges levied against the proprietors of 1337 Services GmbH. FlorainN told former customers they were in the process of moving to a new name and domain for StarkRDP, where existing accounts and balances would be transferred.
“StarkRDP has always been operating by the law and is not involved in any of these alleged crimes and the legal process will confirm this,” the StarkRDP Telegram account wrote on January 30. “All of your servers are safe and they have not been collected in this operation. The only things that were seized is the website server and our domain. Unfortunately, no one can tell who took it and with whom we can talk about it. Therefore, we will restart operation soon, under a different name, to close the chapter [of] ‘StarkRDP.'”
We’re excited to announce the release of McAfee’s Personal Data Cleanup, a new feature that finds and removes your personal info from data brokers and people search sites. Now, you can feel more confident by removing personal info from data broker sites and keeping it from being collected, sold, and used to: advertise products to you, fill your email box with spam, and can even give criminals the info they need to steal your identity. Let’s look at why we’re offering McAfee Personal Data Cleanup, how it protects your privacy, and why it’s a great addition to the online protection we already offer.
There’s so much to enjoy when you live a connected life – free email, online stores that remember what you like, social media that connects you to friends and influencers. It’s a world of convenience, opportunity, and incredible content. It’s also a world where your data is constantly collected.
That’s right, companies are collecting your personal data. They’re called data brokers and they make money by selling information that specifically identifies you, like an email address. They sell this information to marketers looking to target you with ads. Criminals can also use it to build profiles in service of stealing your identity and accessing your accounts. This activity takes place behind the scenes and often without consumers’ knowledge. There are also data brokers known as people search sites that compile and sell info like home addresses, emails, phones, court records, employment info, and more. These websites give identity thieves, hackers, stalkers, and other malicious actors easy access to your info. Regardless of how your data is being used, it’s clear that these days a more connected life often comes at the cost of your privacy.
In a recent survey of McAfee customers, we found that 59% have become more protective of their personal data over the past six months. And it’s no wonder. Over the past two years, trends like telehealth, remote working, and increased usage of online shopping and financial services have meant that more of your time is being spent online. Unsurprisingly, more personal data is being made available in the process. This leads us to the most alarming finding of our survey – 95% of consumers whose personal information ends up on data broker sites had it collected without their consent.
We created Personal Data Cleanup to make it easy for you to take back your privacy online. McAfee’s Personal Data Cleanup regularly scans the riskiest data broker sites for info like your home address, date of birth, and names of relatives. After showing where we found your data, you can either remove it yourself or we will work on your behalf to remove it. Here’s how it works:
Ready to take back your personal info online? Personal Data Cleanup is available immediately with most of our online protection plans. If you have an eligible subscription, you can start using this new feature through McAfee Protection Center, or you can get McAfee online protection here.

Data Privacy Week is here, and there’s no better time to shine a spotlight on one of the biggest players in the personal information economy: data brokers. These entities collect, buy, and sell hundreds—sometimes thousands—of data points on individuals like you. But how do they manage to gather so much information, and for what purpose? From your browsing habits and purchase history to your location data and even more intimate details, these digital middlemen piece together surprisingly comprehensive profiles. The real question is: where are they getting it all, and why is your personal data so valuable to them? Let’s unravel the mystery behind the data broker industry.
Data brokers aggregate user info from various sources on the internet. They collect, collate, package, and sometimes even analyze this data to create a holistic and coherent version of you online. This data then gets put up for sale to nearly anyone who’ll buy it. That can include marketers, private investigators, tech companies, and sometimes law enforcement as well. They’ll also sell to spammers and scammers. (Those bad actors need to get your contact info from somewhere — data brokers are one way to get that and more.)
And that list of potential buyers goes on, which includes but isn’t limited to:
These companies and social media platforms use your data to better understand target demographics and the content with which they interact. While the practice isn’t unethical in and of itself (personalizing user experiences and creating more convenient UIs are usually cited as the primary reasons for it), it does make your data vulnerable to malicious attacks targeted toward big-tech servers.
Most of your online activities are related. Devices like your phone, laptop, tablets, and even fitness watches are linked to each other. Moreover, you might use one email ID for various accounts and subscriptions. This online interconnectedness makes it easier for data brokers to create a cohesive user profile.
Mobile phone apps are the most common way for data brokerage firms to collect your data. You might have countless apps for various purposes, such as financial transactions, health and fitness, or social media.
A number of these apps usually fall under the umbrella of the same or subsidiary family of apps, all of which work toward collecting and supplying data to big tech platforms. Programs like Google’s AdSense make it easier for developers to monetize their apps in exchange for the user information they collect.
Data brokers also collect data points like your home address, full name, phone number, and date of birth. They have automated scraping tools to quickly collect relevant information from public records (think sales of real estate, marriages, divorces, voter registration, and so on).
Lastly, data brokers can gather data from other third parties that track your cookies or even place trackers or cookies on your browsers. Cookies are small data files that track your online activities when visiting different websites. They track your IP address and browsing history, which third parties can exploit. Cookies are also the reason you see personalized ads and products.
Data brokers collate your private information into one package and sell it to “people search” websites. As mentioned above, practically anyone can access these websites and purchase extensive consumer data, for groups of people and individuals alike.
Next, marketing and sales firms are some of data brokers’ biggest clients. These companies purchase massive data sets from data brokers to research your data profile. They have advanced algorithms to segregate users into various consumer groups and target you specifically. Their predictive algorithms can suggest personalized ads and products to generate higher lead generation and conversation percentages for their clients.
We tend to accept the terms and conditions that various apps ask us to accept without thinking twice or reading the fine print. You probably cannot proceed without letting the app track certain data or giving your personal information. To a certain extent, we trade some of our privacy for convenience. This becomes public information, and apps and data brokers collect, track, and use our data however they please while still complying with the law.
There is no comprehensive privacy law in the U.S. on a federal level. This allows data brokers to collect personal information and condense it into marketing insights. While not all methods of gathering private data are legal, it is difficult to track the activities of data brokers online (especially on the dark web). As technology advances, there are also easier ways to harvest and exploit data.
As of March 2024, 15 states in the U.S. have data privacy laws in place. That includes California, Virginia, Connecticut, Colorado, Utah, Iowa, Indiana, Tennessee, Oregon, Montana, Texas, Delaware, Florida, New Jersey, and New Hampshire.[i] The laws vary by state, yet generally, they grant rights to individuals around the collection, use, and disclosure of their personal data by businesses.
However, these laws make exceptions for certain types of data and certain types of collectors. In short, these laws aren’t absolute.
Some data brokers let you remove your information from their websites. There are also extensive guides available online that list the method by which you can opt-out of some of the biggest data brokering firms. For example, a guide by Griffin Boyce, the systems administrator at Harvard University’s Berkman Klein Center for Internet and Society, provides detailed information on how to opt-out of a long list of data broker companies.
Yet the list of data brokers is long. Cleaning up your personal data online can quickly eat up your time, as it requires you to reach out to multiple data brokers and opt-out.
Rather than removing yourself one by one from the host of data broker sites out there, you have a solid option: our Personal Data Cleanup.
Personal Data Cleanup scans data broker sites and shows you which ones are selling your personal info. It also provides guidance on how you can remove your data from those sites. And if you want to save time on manually removing that info, you have options. Our McAfee+ Advanced and Ultimate plans come with full-service Personal Data Cleanup, which sends requests to remove your data automatically.
If the thought of your personal info getting bought and sold in such a public way bothers you, our Personal Data Cleanup can put you back in charge of it.

The post How Data Brokers Sell Your Identity appeared first on McAfee Blog.
Private tech companies gather tremendous amounts of user data. These companies can afford to let you use social media platforms free of charge because it’s paid for by your data, attention, and time.
Big tech derives most of its profits by selling your attention to advertisers — a well-known business model. Various documentaries (like Netflix’s “The Social Dilemma”) have tried to get to the bottom of the complex algorithms that big tech companies employ to mine and analyze user data for the benefit of third-party advertisers.
Tech companies benefit from personal info by being able to provide personalized ads. When you click “yes” at the end of a terms and conditions agreement found on some web pages, you might be allowing the companies to collect the following data:
For someone unfamiliar with privacy issues, it is important to understand the extent of big tech’s tracking and data collection. After these companies collect data, all this info can be supplied to third-party businesses or used to improve user experience.
The problem with this is that big tech has blurred the line between collecting customer data and violating user privacy in some cases. While tracking what content you interact with can be justified under the garb of personalizing the content you see, big tech platforms have been known to go too far. Prominent social networks like Facebook and LinkedIn have faced legal trouble for accessing personal user data like private messages and saved photos.
The info you provide helps build an accurate character profile and turns it into knowledge that gives actionable insights to businesses. Private data usage can be classified into three cases: selling it to data brokers, using it to improve marketing, or enhancing customer experience.
To sell your info to data brokers
Along with big data, another industry has seen rapid growth: data brokers. Data brokers buy, analyze, and package your data. Companies that collect large amounts of data on their users stand to profit from this service. Selling data to brokers is an important revenue stream for big tech companies.
Advertisers and businesses benefit from increased info on their consumers, creating a high demand for your info. The problem here is that companies like Facebook and Alphabet (Google’s parent company) have been known to mine massive amounts of user data for the sake of their advertisers.
To personalize marketing efforts
Marketing can be highly personalized thanks to the availability of large amounts of consumer data. Tracking your response to marketing campaigns can help businesses alter or improve certain aspects of their campaign to drive better results.
The problem is that most AI-based algorithms are incapable of assessing when they should stop collecting or using your info. After a point, users run the risk of being constantly subjected to intrusive ads and other unconsented marketing campaigns that pop up frequently.
To cater to the customer experience
Analyzing consumer behavior through reviews, feedback, and recommendations can help improve customer experience. Businesses have access to various facets of data that can be analyzed to show them how to meet consumer demands. This might help improve any part of a consumer’s interaction with the company, from designing special offers and discounts to improving customer relationships.
For most social media platforms, the goal is to curate a personalized feed that appeals to users and allows them to spend more time on the app. When left unmonitored, the powerful algorithms behind these social media platforms can repeatedly subject you to the same kind of content from different creators.
Here are the big tech companies that collect and mine the most user data.
Users need a comprehensive data privacy solution to tackle the rampant, large-scale data mining carried out by big tech platforms. While targeted advertisements and easily found items are beneficial, many of these companies collect and mine user data through several channels simultaneously, exploiting them in several ways.
It’s important to ensure your personal info is protected. Protection solutions like McAfee’s Personal Data Cleanup feature can help. It scours the web for traces of your personal info and helps remove it for your online privacy.
McAfee+ provides antivirus software for all your digital devices and a secure VPN connection to avoid exposure to malicious third parties while browsing the internet. Our Identity Monitoring and personal data removal solutions further remove gaps in your devices’ security systems.
With our data protection and custom guidance (complete with a protection score for each platform and tips to keep you safer), you can be sure that your internet identity is protected.

McAfee threat researchers have identified several consumer brands and product categories most frequently used by cybercriminals to trick consumers into clicking on malicious links in the first weeks of this holiday shopping season. As holiday excitement peaks and shoppers hunt for the perfect gifts and amazing deals, scammers are taking advantage of the buzz. The National Retail Federation projects holiday spending will reach between $979.5 and $989 billion this year, and cybercriminals are capitalizing by creating scams that mimic the trusted brands and categories consumers trust. From October 1 to November 12, 2024, McAfee safeguarded its customers from 624,346 malicious or suspicious URLs tied to popular consumer brand names – a clear indication that bad actors are exploiting trusted brand names to deceive holiday shoppers.
McAfee’s threat research also reveals a 33.82% spike in malicious URLs targeting consumers with these brands’ names in the run-up to Black Friday and Cyber Monday. This rise in fraudulent activity aligns with holiday shopping patterns during a time when consumers may be more susceptible to clicking on offers from well-known brands like Apple, Yeezy, and Louis Vuitton, especially when deals seem too good to be true – pointing to the need for consumers to stay vigilant, especially with offers that seem unusually generous or come from unverified sources.
McAfee threat researchers have identified a surge in counterfeit sites and phishing scams that use popular luxury brands and tech products to lure consumers into “deals” on fake e-commerce sites designed to appear as official brand pages. While footwear and handbags were identified as the top two product categories exploited by cybercrooks during this festive time, the list of most exploited brands extends beyond those borders:
By mimicking trusted brands like these, offering unbelievable deals, or posing as legitimate customer service channels, cybercrooks create convincing traps designed to steal personal information or money. Here are some of the most common tactics scammers are using this holiday season:
With holiday shopping in full swing, it’s essential for consumers to stay one step ahead of scammers. By understanding the tactics cybercriminals use and taking a few precautionary measures, shoppers can protect themselves from falling victim to fraud. Here are some practical tips for safe shopping this season:
McAfee’s threat research team analyzed malicious or suspicious URLs that McAfee’s web reputation technology identified as targeting customers, by using a list of key company and product brand names—based on insights from a Potter Clarkson report on frequently faked brands—to query the URLs. This methodology captures instances where users either clicked on or were directed to dangerous sites mimicking trusted brands. Additionally, the team queried anonymized user activity from October 1st through November 12th.
The image below is a screenshot of a fake / malicious / scam site: Yeezy is a popular product brand formerly from Adidas found in multiple Malicious/Suspicious URLs. Often, they present themselves as official Yeezy and/or Adidas shopping sites.
The image below is a screenshot of a fake / malicious / scam site: The Apple brand was a popular target for scammers. Many sites were either knock offs, scams, or in this case, a fake customer service page designed to lure users into a scam.
The image below is a screenshot of a fake / malicious / scam site: This particular (fake) Apple sales site used Apple within its URL and name to appear more official. Oddly, this site also sells Samsung Android phones.
The image below is a screenshot of a fake / malicious / scam site: This site, now taken down, is a scam site purporting to sell Nike shoes.
The image below is a screenshot of a fake / malicious / scam site: Louis Vuitton is a popular brand for counterfeit and scams. Particularly their handbags. Here is one site that was entirely focused on Louis Vuitton Handbags.
The image below is a screenshot of a fake / malicious / scam site: This site presents itself as the official Louis Vuitton site selling handbags and clothes.
The image below is a screenshot of a fake / malicious / scam site: This site uses too-good-to-be-true deals on branded items including this Louis Vuitton Bomber jacket.
The image below is a screenshot of a fake / malicious / scam site: Rolex is a popular watch brand for counterfeits and scams. This site acknowledges it sells counterfeits and makes no effort to indicate this on the product.

Two-step verification, two-factor authentication, multi-factor authentication…whatever your social media platform calls it, it’s an excellent way to protect your accounts.
There’s a good chance you’re already using multi-factor verification with your other accounts — for your bank, your finances, your credit card, and any number of things. The way it requires an extra one-time code in addition to your login and password makes life far tougher for hackers.
It’s increasingly common to see nowadays, where all manner of online services only allow access to your accounts after you’ve provided a one-time passcode sent to your email or smartphone. That’s where two-step verification comes in. You get sent a code as part of your usual login process (usually a six-digit number), and then you enter that along with your username and password.
Some online services also offer the option to use an authenticator app, which sends the code to a secure app rather than via email or your smartphone. Authenticator apps work much in the same way, yet they offer three unique features:
Google, Microsoft, and others offer authenticator apps if you want to go that route. You can get a good list of options by checking out the “editor’s picks” at your app store or in trusted tech publications.
Whichever form of authentication you use, always keep that secure code to yourself. It’s yours and yours alone. Anyone who asks for that code, say someone masquerading as a customer service rep, is trying to scam you. With that code, and your username/password combo, they can get into your account.
Passwords and two-step verification work hand-in-hand to keep you safer. Yet not any old password will do. You’ll want a strong, unique password. Here’s how that breaks down:
Now, with strong passwords in place, you can get to setting up multi-factor verification on your social media accounts.
When you set up two-factor authentication on Facebook, you’ll be asked to choose one of three security methods:
And here’s a link to the company’s full walkthrough: https://www.facebook.com/help/148233965247823

The financial technology firm Finastra is investigating the alleged large-scale theft of information from its internal file transfer platform, KrebsOnSecurity has learned. Finastra, which provides software and services to 45 of the world’s top 50 banks, notified customers of the security incident after a cybercriminal began selling more than 400 gigabytes of data purportedly stolen from the company.
London-based Finastra has offices in 42 countries and reported $1.9 billion in revenues last year. The company employs more than 7,000 people and serves approximately 8,100 financial institutions around the world. A major part of Finastra’s day-to-day business involves processing huge volumes of digital files containing instructions for wire and bank transfers on behalf of its clients.
On November 8, 2024, Finastra notified financial institution customers that on Nov. 7 its security team detected suspicious activity on Finastra’s internally hosted file transfer platform. Finastra also told customers that someone had begun selling large volumes of files allegedly stolen from its systems.
“On November 8, a threat actor communicated on the dark web claiming to have data exfiltrated from this platform,” reads Finastra’s disclosure, a copy of which was shared by a source at one of the customer firms.
“There is no direct impact on customer operations, our customers’ systems, or Finastra’s ability to serve our customers currently,” the notice continued. “We have implemented an alternative secure file sharing platform to ensure continuity, and investigations are ongoing.”
But its notice to customers does indicate the intruder managed to extract or “exfiltrate” an unspecified volume of customer data.
“The threat actor did not deploy malware or tamper with any customer files within the environment,” the notice reads. “Furthermore, no files other than the exfiltrated files were viewed or accessed. We remain focused on determining the scope and nature of the data contained within the exfiltrated files.”
In a written statement in response to questions about the incident, Finastra said it has been “actively and transparently responding to our customers’ questions and keeping them informed about what we do and do not yet know about the data that was posted.” The company also shared an updated communication to its clients, which said while it was still investigating the root cause, “initial evidence points to credentials that were compromised.”
“Additionally, we have been sharing Indicators of Compromise (IOCs) and our CISO has been speaking directly with our customers’ security teams to provide updates on the investigation and our eDiscovery process,” the statement continues. Here is the rest of what they shared:
“In terms of eDiscovery, we are analyzing the data to determine what specific customers were affected, while simultaneously assessing and communicating which of our products are not dependent on the specific version of the SFTP platform that was compromised. The impacted SFTP platform is not used by all customers and is not the default platform used by Finastra or its customers to exchange data files associated with a broad suite of our products, so we are working as quickly as possible to rule out affected customers. However, as you can imagine, this is a time-intensive process because we have many large customers that leverage different Finastra products in different parts of their business. We are prioritizing accuracy and transparency in our communications.
Importantly, for any customers who are deemed to be affected, we will be reaching out and working with them directly.”
On Nov. 8, a cybercriminal using the nickname “abyss0” posted on the English-language cybercrime community BreachForums that they’d stolen files belonging to some of Finastra’s largest banking clients. The data auction did not specify a starting or “buy it now” price, but said interested buyers should reach out to them on Telegram.
abyss0’s Nov. 7 sales thread on BreachForums included many screenshots showing the file directory listings for various Finastra customers. Image: Ke-la.com.
According to screenshots collected by the cyber intelligence platform Ke-la.com, abyss0 first attempted to sell the data allegedly stolen from Finastra on October 31, but that earlier sales thread did not name the victim company. However, it did reference many of the same banks called out as Finastra customers in the Nov. 8 post on BreachForums.
The original October 31 post from abyss0, where they advertise the sale of data from several large banks that are customers of a large financial software company. Image: Ke-la.com.
The October sales thread also included a starting price: $20,000. By Nov. 3, that price had been reduced to $10,000. A review of abyss0’s posts to BreachForums reveals this user has offered to sell databases stolen in several dozen other breaches advertised over the past six months.
The apparent timeline of this breach suggests abyss0 gained access to Finastra’s file sharing system at least a week before the company says it first detected suspicious activity, and that the Nov. 7 activity cited by Finastra may have been the intruder returning to exfiltrate more data.
Maybe abyss0 found a buyer who paid for their early retirement. We may never know, because this person has effectively vanished. The Telegram account that abyss0 listed in their sales thread appears to have been suspended or deleted. Likewise, abyss0’s account on BreachForums no longer exists, and all of their sales threads have since disappeared.
It seems improbable that both Telegram and BreachForums would have given this user the boot at the same time. The simplest explanation is that something spooked abyss0 enough for them to abandon a number of pending sales opportunities, in addition to a well-manicured cybercrime persona.
In March 2020, Finastra suffered a ransomware attack that sidelined a number of the company’s core businesses for days. According to reporting from Bloomberg, Finastra was able to recover from that incident without paying a ransom.

In December 2023, KrebsOnSecurity revealed the real-life identity of Rescator, the nickname used by a Russian cybercriminal who sold more than 100 million payment cards stolen from Target and Home Depot between 2013 and 2014. Moscow resident Mikhail Shefel, who confirmed using the Rescator identity in a recent interview, also admitted reaching out because he is broke and seeking publicity for several new money making schemes.
Mikhail “Mike” Shefel’s former Facebook profile. Shefel has since legally changed his last name to Lenin.
Mr. Shefel, who recently changed his legal surname to Lenin, was the star of last year’s story, Ten Years Later, New Clues in the Target Breach. That investigation detailed how the 38-year-old Shefel adopted the nickname Rescator while working as vice president of payments at ChronoPay, a Russian financial company that paid spammers to advertise fake antivirus scams, male enhancement drugs and knockoff pharmaceuticals.
Mr. Shefel did not respond to requests for comment in advance of that December 2023 profile. Nor did he respond to reporting here in January 2024 that he ran an IT company with a 34-year-old Russian man named Aleksandr Ermakov, who was sanctioned by authorities in Australia, the U.K. and U.S. for stealing data on nearly 10 million customers of the Australian health insurance giant Medibank.
But not long after KrebsOnSecurity reported in April that Shefel/Rescator also was behind the theft of Social Security and tax information from a majority of South Carolina residents in 2012, Mr. Shefel began contacting this author with the pretense of setting the record straight on his alleged criminal hacking activities.
In a series of live video chats and text messages, Mr. Shefel confirmed he indeed went by the Rescator identity for several years, and that he did operate a slew of websites between 2013 and 2015 that sold payment card data stolen from Target, Home Depot and a number of other nationwide retail chains.
Shefel claims the true mastermind behind the Target and other retail breaches was Dmitri Golubov, an infamous Ukrainian hacker known as the co-founder of Carderplanet, among the earliest Russian-language cybercrime forums focused on payment card fraud. Mr. Golubov could not be reached for comment, and Shefel says he no longer has the laptop containing evidence to support that claim.
Shefel asserts he and his team were responsible for developing the card-stealing malware that Golubov’s hackers installed on Target and Home Depot payment terminals, and that at the time he was technical director of a long-running Russian cybercrime community called Lampeduza.
“My nickname was MikeMike, and I worked with Dmitri Golubov and made technologies for him,” Shefel said. “I’m also godfather of his second son.”
Dmitri Golubov, circa 2005. Image: U.S. Postal Investigative Service.
A week after breaking the story about the 2013 data breach at Target, KrebsOnSecurity published Who’s Selling Cards from Target?, which identified a Ukrainian man who went by the nickname Helkern as Rescator’s original identity. But Shefel claims Helkern was subordinate to Golubov, and that he was responsible for introducing the two men more than a decade ago.
“Helkern was my friend, I [set up a] meeting with Golubov and him in 2013,” Shefel said. “That was in Odessa, Ukraine. I was often in that city, and [it’s where] I met my second wife.”
Shefel claims he made several hundred thousand dollars selling cards stolen by Golubov’s Ukraine-based hacking crew, but that not long after Russia annexed Crimea in 2014 Golubov cut him out of the business and replaced Shefel’s malware coding team with programmers in Ukraine.
Golubov was arrested in Ukraine in 2005 as part of a joint investigation with multiple U.S. federal law enforcement agencies, but his political connections in the country ensured his case went nowhere. Golubov later earned immunity from prosecution by becoming an elected politician and founding the Internet Party of Ukraine, which called for free internet for all, the creation of country-wide “hacker schools” and the “computerization of the entire economy.”
Mr. Shefel says he stopped selling stolen payment cards after being pushed out of the business, and invested his earnings in a now-defunct Russian search engine called tf[.]org. He also apparently ran a business called click2dad[.]net that paid people to click on ads for Russian government employment opportunities.
When those enterprises fizzled out, Shefel reverted to selling malware coding services for hire under the nickname “Getsend“; this claim checks out, as Getsend for many years advertised the same Telegram handle that Shefel used in our recent chats and video calls.
Shefel acknowledged that his outreach was motivated by a desire to publicize several new business ventures. None of those will be mentioned here because Shefel is already using my December 2023 profile of him to advertise what appears to be a pyramid scheme, and to remind others within the Russian hacker community of his skills and accomplishments.
Shefel says he is now flat broke, and that he currently has little to show for a storied hacking career. The Moscow native said he recently heard from his ex-wife, who had read last year’s story about him and was suddenly wondering where he’d hidden all of his earnings.
More urgently, Shefel needs money to stay out of prison. In February, he and Ermakov were arrested on charges of operating a short-lived ransomware affiliate program in 2021 called Sugar (a.k.a. Sugar Locker), which targeted single computers and end-users instead of corporations. Shefel is due to face those charges in a Moscow court on Friday, Nov. 15, 2024. Ermakov was recently found guilty and given two years probation.
Shefel claims his Sugar ransomware affiliate program was a bust, and never generated any profits. Russia is known for not prosecuting criminal hackers within its borders who scrupulously avoid attacking Russian businesses and consumers. When asked why he now faces prosecution over Sugar, Shefel said he’s certain the investigation was instigated by Pyotr “Peter” Vrublevsky — the son of his former boss at ChronoPay.
ChronoPay founder and CEO Pavel Vrublevsky was the key subject of my 2014 book Spam Nation, which described his role as head of one of Russia’s most notorious criminal spam operations.
Vrublevsky Sr. recently declared bankruptcy, and is currently in prison on fraud charges. Russian authorities allege Vrublevsky operated several fraudulent SMS-based payment schemes. They also accused Vrublevsky of facilitating money laundering for Hydra, the largest Russian darknet market at the time. Hydra trafficked in illegal drugs and financial services, including cryptocurrency tumbling for money laundering, exchange services between cryptocurrency and Russian rubles, and the sale of falsified documents and hacking services.
However, in 2022 KrebsOnSecurity reported on a more likely reason for Vrublevsky’s latest criminal charges: He’d been extensively documenting the nicknames, real names and criminal exploits of Russian hackers who worked with the protection of corrupt officials in the Russian Federal Security Service (FSB), and operating a Telegram channel that threatened to expose alleged nefarious dealings by Russian financial executives.
Shefel believes Vrublevsky’s son Peter paid corrupt cops to levy criminal charges against him after reporting the youth to Moscow police, allegedly for walking around in public with a loaded firearm. Shefel says the Russian authorities told the younger Vrublevsky that he had lodged the firearms complaint.
In July 2024, the Russian news outlet Izvestia published a lengthy investigation into Peter Vrublevsky, alleging that the younger son took up his father’s mantle and was responsible for advertising Sprut, a Russian-language narcotics bazaar that sprang to life after the Hydra darknet market was shut down by international law enforcement agencies in 2022.
Izvestia reports that Peter Vrublevsky was the advertising mastermind behind this 3D ad campaign and others promoting the Russian online narcotics bazaar Sprut.
Izvestia reports that Peter Vrublevsky is currently living in Switzerland, where he reportedly fled in 2022 after being “arrested in absentia” in Russia on charges of running a violent group that could be hired via Telegram to conduct a range of physical attacks in real life, including firebombings and muggings.
Shefel claims his former partner Golubov was involved in the development and dissemination of early ransomware strains, including Cryptolocker, and that Golubov remains active in the cybercrime community.
Meanwhile, Mr. Shefel portrays himself as someone who is barely scraping by with the few odd coding jobs that come his way each month. Incredibly, the day after our initial interview via Telegram, Shefel proposed going into business together.
By way of example, he suggested maybe a company centered around recovering lost passwords for cryptocurrency accounts, or perhaps a series of online retail stores that sold cheap Chinese goods at a steep markup in the United States.
“Hi, how are you?” he inquired. “Maybe we can open business?”
The Federal Bureau of Investigation (FBI) is urging police departments and governments worldwide to beef up security around their email systems, citing a recent increase in cybercriminal services that use hacked police email accounts to send unauthorized subpoenas and customer data requests to U.S.-based technology companies.
In an alert (PDF) published this week, the FBI said it has seen an uptick in postings on criminal forums regarding the process of emergency data requests (EDRs) and the sale of email credentials stolen from police departments and government agencies.
“Cybercriminals are likely gaining access to compromised US and foreign government email addresses and using them to conduct fraudulent emergency data requests to US based companies, exposing the personal information of customers to further use for criminal purposes,” the FBI warned.
In the United States, when federal, state or local law enforcement agencies wish to obtain information about an account at a technology provider — such as the account’s email address, or what Internet addresses a specific cell phone account has used in the past — they must submit an official court-ordered warrant or subpoena.
Virtually all major technology companies serving large numbers of users online have departments that routinely review and process such requests, which are typically granted (eventually, and at least in part) as long as the proper documents are provided and the request appears to come from an email address connected to an actual police department domain name.
In some cases, a cybercriminal will offer to forge a court-approved subpoena and send that through a hacked police or government email account. But increasingly, thieves are relying on fake EDRs, which allow investigators to attest that people will be bodily harmed or killed unless a request for account data is granted expeditiously.
The trouble is, these EDRs largely bypass any official review and do not require the requester to supply any court-approved documents. Also, it is difficult for a company that receives one of these EDRs to immediately determine whether it is legitimate.
In this scenario, the receiving company finds itself caught between two unsavory outcomes: Failing to immediately comply with an EDR — and potentially having someone’s blood on their hands — or possibly leaking a customer record to the wrong person.
Perhaps unsurprisingly, compliance with such requests tends to be extremely high. For example, in its most recent transparency report (PDF) Verizon said it received more than 127,000 law enforcement demands for customer data in the second half of 2023 — including more than 36,000 EDRs — and that the company provided records in response to approximately 90 percent of requests.
One English-speaking cybercriminal who goes by the nicknames “Pwnstar” and “Pwnipotent” has been selling fake EDR services on both Russian-language and English cybercrime forums. Their prices range from $1,000 to $3,000 per successful request, and they claim to control “gov emails from over 25 countries,” including Argentina, Bangladesh, Brazil, Bolivia, Dominican Republic, Hungary, India, Kenya, Jordan, Lebanon, Laos, Malaysia, Mexico, Morocco, Nigeria, Oman, Pakistan, Panama, Paraguay, Peru, Philippines, Tunisia, Turkey, United Arab Emirates (UAE), and Vietnam.
“I cannot 100% guarantee every order will go through,” Pwnstar explained. “This is social engineering at the highest level and there will be failed attempts at times. Don’t be discouraged. You can use escrow and I give full refund back if EDR doesn’t go through and you don’t receive your information.”

A review of EDR vendors across many cybercrime forums shows that some fake EDR vendors sell the ability to send phony police requests to specific social media platforms, including forged court-approved documents. Others simply sell access to hacked government or police email accounts, and leave it up to the buyer to forge any needed documents.
“When you get account, it’s yours, your account, your liability,” reads an ad in October on BreachForums. “Unlimited Emergency Data Requests. Once Paid, the Logins are completely Yours. Reset as you please. You would need to Forge Documents to Successfully Emergency Data Request.”
Still other fake EDR service vendors claim to sell hacked or fraudulently created accounts on Kodex, a startup that aims to help tech companies do a better job screening out phony law enforcement data requests. Kodex is trying to tackle the problem of fake EDRs by working directly with the data providers to pool information about police or government officials submitting these requests, with an eye toward making it easier for everyone to spot an unauthorized EDR.
If police or government officials wish to request records regarding Coinbase customers, for example, they must first register an account on Kodexglobal.com. Kodex’s systems then assign that requestor a score or credit rating, wherein officials who have a long history of sending valid legal requests will have a higher rating than someone sending an EDR for the first time.
It is not uncommon to see fake EDR vendors claim the ability to send data requests through Kodex, with some even sharing redacted screenshots of police accounts at Kodex.
Matt Donahue is the former FBI agent who founded Kodex in 2021. Donahue said just because someone can use a legitimate police department or government email to create a Kodex account doesn’t mean that user will be able to send anything. Donahue said even if one customer gets a fake request, Kodex is able to prevent the same thing from happening to another.
Kodex told KrebsOnSecurity that over the past 12 months it has processed a total of 1,597 EDRs, and that 485 of those requests (~30 percent) failed a second-level verification. Kodex reports it has suspended nearly 4,000 law enforcement users in the past year, including:
-1,521 from the Asia-Pacific region;
-1,290 requests from Europe, the Middle East and Asia;
-460 from police departments and agencies in the United States;
-385 from entities in Latin America, and;
-285 from Brazil.
Donahue said 60 technology companies are now routing all law enforcement data requests through Kodex, including an increasing number of financial institutions and cryptocurrency platforms. He said one concern shared by recent prospective customers is that crooks are seeking to use phony law enforcement requests to freeze and in some cases seize funds in specific accounts.
“What’s being conflated [with EDRs] is anything that doesn’t involve a formal judge’s signature or legal process,” Donahue said. “That can include control over data, like an account freeze or preservation request.”
In a hypothetical example, a scammer uses a hacked government email account to request that a service provider place a hold on a specific bank or crypto account that is allegedly subject to a garnishment order, or party to crime that is globally sanctioned, such as terrorist financing or child exploitation.
A few days or weeks later, the same impersonator returns with a request to seize funds in the account, or to divert the funds to a custodial wallet supposedly controlled by government investigators.
“In terms of overall social engineering attacks, the more you have a relationship with someone the more they’re going to trust you,” Donahue said. “If you send them a freeze order, that’s a way to establish trust, because [the first time] they’re not asking for information. They’re just saying, ‘Hey can you do me a favor?’ And that makes the [recipient] feel valued.”
Echoing the FBI’s warning, Donahue said far too many police departments in the United States and other countries have poor account security hygiene, and often do not enforce basic account security precautions — such as requiring phishing-resistant multifactor authentication.
How are cybercriminals typically gaining access to police and government email accounts? Donahue said it’s still mostly email-based phishing, and credentials that are stolen by opportunistic malware infections and sold on the dark web. But as bad as things are internationally, he said, many law enforcement entities in the United States still have much room for improvement in account security.
“Unfortunately, a lot of this is phishing or malware campaigns,” Donahue said. “A lot of global police agencies don’t have stringent cybersecurity hygiene, but even U.S. dot-gov emails get hacked. Over the last nine months, I’ve reached out to CISA (the Cybersecurity and Infrastructure Security Agency) over a dozen times about .gov email addresses that were compromised and that CISA was unaware of.”
Change Healthcare says it has notified approximately 100 million Americans that their personal, financial and healthcare records may have been stolen in a February 2024 ransomware attack that caused the largest ever known data breach of protected health information.

A ransomware attack at Change Healthcare in the third week of February quickly spawned disruptions across the U.S. healthcare system that reverberated for months, thanks to the company’s central role in processing payments and prescriptions on behalf of thousands of organizations.
In April, Change estimated the breach would affect a “substantial proportion of people in America.” On Oct 22, the healthcare giant notified the U.S. Department of Health and Human Resources (HHS) that “approximately 100 million notices have been sent regarding this breach.”
A notification letter from Change Healthcare said the breach involved the theft of:
-Health Data: Medical record #s, doctors, diagnoses, medicines, test results, images, care and treatment;
-Billing Records: Records including payment cards, financial and banking records;
-Personal Data: Social Security number; driver’s license or state ID number;
-Insurance Data: Health plans/policies, insurance companies, member/group ID numbers, and Medicaid-Medicare-government payor ID numbers.
The HIPAA Journal reports that in the nine months ending on September 30, 2024, Change’s parent firm United Health Group had incurred $1.521 billion in direct breach response costs, and $2.457 billion in total cyberattack impacts.
Those costs include $22 million the company admitted to paying their extortionists — a ransomware group known as BlackCat and ALPHV — in exchange for a promise to destroy the stolen healthcare data.
That ransom payment went sideways when the affiliate who gave BlackCat access to Change’s network said the crime gang had cheated them out of their share of the ransom. The entire BlackCat ransomware operation shut down after that, absconding with all of the money still owed to affiliates who were hired to install their ransomware.
A breach notification from Change Healthcare.
A few days after BlackCat imploded, the same stolen healthcare data was offered for sale by a competing ransomware affiliate group called RansomHub.
“Affected insurance providers can contact us to prevent leaking of their own data and [remove it] from the sale,” RansomHub’s victim shaming blog announced on April 16. “Change Health and United Health processing of sensitive data for all of these companies is just something unbelievable. For most US individuals out there doubting us, we probably have your personal data.”
It remains unclear if RansomHub ever sold the stolen healthcare data. The chief information security officer for a large academic healthcare system affected by the breach told KrebsOnSecurity they participated in a call with the FBI and were told a third party partner managed to recover at least four terabytes of data that was exfiltrated from Change by the cybercriminal group. The FBI declined to comment.
Change Healthcare’s breach notification letter offers recipients two years of credit monitoring and identity theft protection services from a company called IDX. In the section of the missive titled “Why did this happen?,” Change shared only that “a cybercriminal accessed our computer system without our permission.”
But in June 2024 testimony to the Senate Finance Committee, it emerged that the intruders had stolen or purchased credentials for a Citrix portal used for remote access, and that no multi-factor authentication was required for that account.
Last month, Sens. Mark Warner (D-Va.) and Ron Wyden (D-Ore.) introduced a bill that would require HHS to develop and enforce a set of tough minimum cybersecurity standards for healthcare providers, health plans, clearinghouses and businesses associates. The measure also would remove the existing cap on fines under the Health Insurance Portability and Accountability Act, which severely limits the financial penalties HHS can issue against providers.
According to the HIPAA Journal, the biggest penalty imposed to date for a HIPAA violation was the paltry $16 million fine against the insurer Anthem Inc., which suffered a data breach in 2015 affecting 78.8 million individuals. Anthem reported revenues of around $80 billion in 2015.

There is little that victims of this breach can do about the compromise of their healthcare records. However, because the data exposed includes more than enough information for identity thieves to do their thing, it would be prudent to place a security freeze on your credit file and on that of your family members if you haven’t already.
The best mechanism for preventing identity thieves from creating new accounts in your name is to freeze your credit file with Equifax, Experian, and TransUnion. This process is now free for all Americans, and simply blocks potential creditors from viewing your credit file. Parents and guardians can now also freeze the credit files for their children or dependents.
Since very few creditors are willing to grant new lines of credit without being able to determine how risky it is to do so, freezing your credit file with the Big Three is a great way to stymie all sorts of ID theft shenanigans. Having a freeze in place does nothing to prevent you from using existing lines of credit you may already have, such as credit cards, mortgage and bank accounts. When and if you ever do need to allow access to your credit file — such as when applying for a loan or new credit card — you will need to lift or temporarily thaw the freeze in advance with one or more of the bureaus.
All three bureaus allow users to place a freeze electronically after creating an account, but all of them try to steer consumers away from enacting a freeze. Instead, the bureaus are hoping consumers will opt for their confusingly named “credit lock” services, which accomplish the same result but allow the bureaus to continue selling access to your file to select partners.
If you haven’t done so in a while, now would be an excellent time to review your credit file for any mischief or errors. By law, everyone is entitled to one free credit report every 12 months from each of the three credit reporting agencies. But the Federal Trade Commission notes that the big three bureaus have permanently extended a program enacted in 2020 that lets you check your credit report at each of the agencies once a week for free.
Brazilian authorities reportedly have arrested a 33-year-old man on suspicion of being “USDoD,” a prolific cybercriminal who rose to infamy in 2022 after infiltrating the FBI’s InfraGard program and leaking contact information for 80,000 members. More recently, USDoD was behind a breach at the consumer data broker National Public Data that led to the leak of Social Security numbers and other personal information for a significant portion of the U.S. population.
USDoD’s InfraGard sales thread on Breached.
The Brazilian news outlet TV Globo first reported the news of USDoD’s arrest, saying the Federal Police arrested a 33-year-old man from Belo Horizonte. According to TV Globo, USDoD is wanted domestically in connection with the theft of data on Brazilian Federal Police officers.
USDoD was known to use the hacker handles “Equation Corp” and “NetSec,” and according to the cyber intelligence platform Intel 471 NetSec posted a thread on the now-defunct cybercrime community RaidForums on Feb. 22, 2022, in which they offered the email address and password for 659 members of the Brazilian Federal Police.
TV Globo didn’t name the man arrested, but the Portuguese tech news outlet Tecmundo published a report in August 2024 that named USDoD as 33-year-old Luan BG from Minas Gerais, Brazil. Techmundo said it learned the hacker’s real identity after being given a draft of a detailed, non-public report produced by the security firm CrowdStrike.
CrowdStrike did not respond to a request for comment. But a week after Techmundo’s piece, the tech news publication hackread.com published a story in which USDoD reportedly admitted that CrowdStrike was accurate in identifying him. Hackread said USDoD shared a statement, which was partially addressed to CrowdStrike:

In August 2024, a cybercriminal began selling Social Security numbers and other personal information stolen from National Public Data, a private data broker in Florida that collected and sold SSNs and contact data for a significant slice of the American population.
Additional reporting revealed National Public Data had inadvertently published its own passwords on the Internet. The company is now the target of multiple class-action lawsuits, and recently declared bankruptcy. In an interview with KrebsOnSecurity, USDoD acknowledged stealing the NPD data earlier this year, but claimed he was not involved in leaking or selling it.
In December 2022, KrebsOnSecurity broke the news that USDoD had social-engineered his way into the FBI’s InfraGard program, an FBI initiative designed to build informal information sharing partnerships with vetted professionals in the private sector concerning cyber and physical threats to critical U.S. national infrastructure.
USDoD applied for InfraGard membership using the identity of the CEO of a major U.S. financial company. Even though USDoD listed the real mobile phone number of the CEO, the FBI apparently never reached the CEO to validate his application, because the request was granted just a few weeks later. After that, USDoD said he used a simple program to collect all of the contact information shared by more than 80,000 InfraGard members.
The FBI declined to comment on reports about USDoD’s arrest.
In a lengthy September 2023 interview with databreaches.net, USDoD told the publication he was a man in his mid-30s who was born in South America and who holds dual citizenship in Brazil and Portugal. Toward the end of that interview, USDoD said they were planning to launch a platform for acquiring military intelligence from the United States.
Databreaches.net told KrebsOnSecurity USDoD has been a regular correspondent since that 2023 interview, and that after being doxed USDoD made inquiries with a local attorney to learn if there were any open investigations or charges against him.
“From what the lawyer found out from the federal police, they had no open cases or charges against him at that time,” Databreaches.net said. “From his writing to me and the conversations we had, my sense is he had absolutely no idea he was in imminent danger of being arrested.”
When KrebsOnSecurity last communicated with USDoD via Telegram on Aug. 15, 2024, they claimed they were “planning to retire and move on from this,” referring to multiple media reports that blamed USDoD for leaking nearly three billion consumer records from National Public Data.
Less than four days later, however, USDoD was back on his normal haunt at BreachForums, posting custom exploit code he claimed to have written to attack recently patched vulnerabilities in a popular theme made for WordPress websites.
