I've always thought of it a bit like baseball cards; a kid has a card of this one player that another kid is keen on, and that kid has a card the first one wants so they make a trade. They both have a bunch of cards they've collected over time and by virtue of existing in the same social circles, trades are frequent, and cards flow back and forth on a regular basis. That's the analogy I often use to describe the data breach "personal stash" ecosystem, but with one key difference: if you trade a baseball card then you no longer have the original card, but if you trade a data breach which is merely a digital file, it replicates.
There are personal stashes of data breaches all over the place and they're usually presented like this one:
You'll recognise many of those names because they're noteworthy incidents that received a bunch of press. My Space. Adobe. LinkedIn. Ashley Madison.
The same incidents appear here:
And so on and so forth. Stashes of breaches like this are all over the place and they fuel an exchange ecosystem that replicates billions of records of personal data over and over again. Your data. My data. The data of a significant portion of the global internet-using population, just freely flowing backwards and forwards not just in the shady corners of "the dark web" but traded out there in the clear on mainstream websites. Until inevitably:
Diogo Santos Coelho was 14 when he started RaidForums, and was 21 by the time he was arrested for running the service 2 years ago. A kid, exchanging data without the maturity to understand the consequences of his actions. RaidForums left a void that was quickly filled by BreachForums:
Conor Fitzpatrick was 20 years old when he was finally picked up for running the service last year. Still just a kid, at least in the colloquial fashion in which we refer to youngsters as when we get a bit older, but surely still legally a minor when he chose to begin collecting data breaches.
Websites like these are taken down for a simple reason:
The ecosystem of personal stashes exchanged with other parties fuels crime.
For example, data breaches seed services set up with the express intent of monetising a broad range of personal attributes to the detriment of people who are already victims of a breach. Call them shady versions of Have I Been Pwned if you will, and this talk I gave at AusCERT a couple of years ago is a great explainer (deep-linked to the start of that segment):
The first service I spoke about in that segment was We Leak Info and it was run by two 22 year old guys. The website first appeared 3 years earlier - only a year after the creators had left childhood - and it allowed anyone with the money to access anyone else's personal data including:
names, email addresses, usernames, phone numbers, and passwords
One of the duo was later sentenced to 2 years in prison for his role, and when you read the sorts of conversations they were having, you can't help but think they behaved exactly like you'd expect a couple of young guys who thought they were anonymous would:
In the video, I mentioned Jordan Bloom in relation to LeakedSource, a veritable older gentleman of this class of crime being 24 when the site first appeared.
The company operating LeakedSource, Defiant Tech Inc, which was founded by Jordan Bloom, eventually entered a guilty plea to charges that included trafficking in identity information and when you read what that involved, you can see why this would attract the ire of law enforcement agencies:
However, unlike other breach notification services, such as Have I Been Pwned, LeakedSource also gave subscribers access to usernames, passwords (including in clear text), email addresses and IP addresses. LeakedSource services were often advertised on hacking forums and there was suspicion that its operators were actively looking to hack organizations whose data they could add to their database.
In 2016, a well-wisher purchased my own data from LeakedSource and sent over a dozen different records similar to this one:
Not mentioned in my talk but running in the same era was Leakbase, yet another service that collated huge volumes of sensitive data and sold it to absolutely anyone:
And just like all the other ones, the same data appeared over and over again:
It went dark at the end of 2017 amidst speculation the disappearance was tied to the takedown of the Hansa dark web market. If that was the case, why did we never hear of charges being laid as we did with We Leak Info and LeakedSource? Could it be that the operator of Leakbase was only ever so slightly younger than the other guys mentioned above and not having yet reached adulthood, managed to dodge charges? It would certainly be consistent with the demographic pattern of those with personal stashes of data breaches.
Speaking of patterns: We Leak Info, LeakedSource, Leakbase - it's like there's a theme of shady services attached to the word. As I say in the video, there's also a theme of attempting to remain anonymous (which clearly hasn't worked very well!), and a theme of attempting to eschew legal responsibility for how the data is used by merely putting words in the terms of service. For example, here's Jordan's go at deflecting his role in the ecosystem and yes, this was the entire terms of service:
I particularly like this clause:
You may only use this tool for your own personal security and data research. You may only search information about yourself, or those you are authorized in writing to do so.
That's not going to keep you out of trouble! Time and time again, I see this sort of wording on services used as if it's going to make a difference when the law comes asking hard questions; "Hey we literally told people to play nice with the data!"
We Leak Info used similar entertaining wording with some of the highlights including:
That last one in particular is an absolute zinger! But again, remember, we're talking about guys who stood this service up as teenagers and literally worked on the assumption of "as [l]ong as we cooperate they [the FBI] won't fuck with us" 🤦♂️ The ignorance of that attitude whilst advertising services on criminal forums is just mind-blowing, even for kids.
All of which brings me to the inspiration for this blog post:
Interesting find by @MayhemDayOne, wonder if it was from a shady breach search service (we’ve seen a bunch shut down over the years)? Either way, collecting and storing this data is now trivial so not a big surprise to see someone screw up their permissions and (re)leak it all. https://t.co/DM7udeUcRk

It's like I've seen it all before! No, really, because only a couple of days later someone running a service popped up and claimed responsibility for having exposed the data due to "a firewall misconfiguration". I'm not going to name or link the service, but I will describe a few key features:
I could write predictions about the future of this service but if you've read this far and paid attention to the precedents, you can reliably form your own conclusion. The outcome is easily predictable and indeed it was the predictability of the whole situation when I started getting bombarded with queries about the "Mother of all Breaches" that frustrated me; of course it was someone's personal stash, because we've seen it all before and we live in an era where it's dead easy to build services like this. Cloud is ubiquitous and storage is cheap, you can stand up great looking websites in next to no time courtesy of freely available templates, and the whole data breach trading ecosystem I referred to earlier can easily seed services like this.
Maybe the young guy running this service (assuming the previously observed patterns apply) will learn from history and quietly exit while the getting is good, I don't know, time will tell. At the very least, if he reads this and takes nothing else away, don't go driving around in a bright green Lamborghini!
Edit: In the original version of this blog post, it was incorrectly implied that Jordan Bloom may have been the person who pled guilty to charges when in fact it was the company that ran LeakedSource, Defiant Tech Inc, that the plea was entered under. To the extent that the blog contained words to the effect of, or otherwise implied or contained innuendo that Mr Bloom engaged in criminal or otherwise illegal conduct, or pled guilty to trafficking identify information, I apologise and unreservedly retract such statements and this blog has been edited to ensure that the facts involved in this matter are accurately portrayed.

I spent longer than I expected talking about Trello this week, in part because I don't feel the narrative they presented properly acknowledges their responsibility for the incident and in part because I think the impact of scraping in general is misunderstood. I suspect many of us are prone to looking at this in a very binary fashion: if the data is publicly accessible anyway, scraping it poses no risk. But in my view, there's a hell of a big difference between say, looking at one person's personal info on LinkedIn via the browser versus having a corpus of millions of records of the same data saved offline. That's before we even get into the issue of whether in Trello's case, it should ever be possible for a third party to match email address to username and IRL name.
To add some more perspective, I've just posted a poll immediately before publishing this blog post, let's see what the masses have to say:
Scraping: should we be concerned if an individual's personal data is scraped, aggregated en mass and redistributed if that same data is already publicly accessible on the service anyway? Vote and if possible, add more context in a reply.

Authorities in Australia, the United Kingdom and the United States this week levied financial sanctions against a Russian man accused of stealing data on nearly 10 million customers of the Australian health insurance giant Medibank. 33-year-old Aleksandr Ermakov allegedly stole and leaked the Medibank data while working with one of Russia’s most destructive ransomware groups, but little more is shared about the accused. Here’s a closer look at the activities of Mr. Ermakov’s alleged hacker handles.

The allegations against Ermakov mark the first time Australia has sanctioned a cybercriminal. The documents released by the Australian government included multiple photos of Mr. Ermakov, and it was clear they wanted to send a message that this was personal.
It’s not hard to see why. The attackers who broke into Medibank in October 2022 stole 9.7 million records on current and former Medibank customers. When the company refused to pay a $10 million ransom demand, the hackers selectively leaked highly sensitive health records, including those tied to abortions, HIV and alcohol abuse.
The U.S. government says Ermakov and the other actors behind the Medibank hack are believed to be linked to the Russia-backed cybercrime gang REvil.
“REvil was among the most notorious cybercrime gangs in the world until July 2021 when they disappeared. REvil is a ransomware-as-a-service (RaaS) operation and generally motivated by financial gain,” a statement from the U.S. Department of the Treasury reads. “REvil ransomware has been deployed on approximately 175,000 computers worldwide, with at least $200 million paid in ransom.”
The sanctions say Ermakov went by multiple aliases on Russian cybercrime forums, including GustaveDore, JimJones, and Blade Runner. A search on the handle GustaveDore at the cyber intelligence platform Intel 471 shows this user created a ransomware affiliate program in November 2021 called Sugar (a.k.a. Encoded01), which focused on targeting single computers and end-users instead of corporations.
An ad for the ransomware-as-a-service program Sugar posted by GustaveDore warns readers against sharing information with security researchers, law enforcement, or “friends of Krebs.”
In November 2020, Intel 471 analysts concluded that GustaveDore’s alias JimJones “was using and operating several different ransomware strains, including a private undisclosed strain and one developed by the REvil gang.”
In 2020, GustaveDore advertised on several Russian discussion forums that he was part of a Russian technology firm called Shtazi, which could be hired for computer programming, web development, and “reputation management.” Shtazi’s website remains in operation today.
A Google-translated version of Shtazi dot ru. Image: Archive.org.
The third result when one searches for shtazi[.]ru in Google is an Instagram post from a user named Mikhail Borisovich Shefel, who promotes Shtazi’s services as if it were also his business. If this name sounds familiar, it’s because in December 2023 KrebsOnSecurity identified Mr. Shefel as “Rescator,” the cybercriminal identity tied to tens of millions of payment cards that were stolen in 2013 and 2014 from big box retailers Target and Home Depot, among others.
How close was the connection between GustaveDore and Mr. Shefel? The Treasury Department’s sanctions page says Ermakov used the email address ae.ermak@yandex.ru. A search for this email at DomainTools.com shows it was used to register just one domain name: millioner1[.]com. DomainTools further finds that a phone number tied to Mr. Shefel (79856696666) was used to register two domains: millioner[.]pw, and shtazi[.]net.
The December 2023 story here that outed Mr. Shefel as Rescator noted that Shefel recently changed his last name to “Lenin” and had launched a service called Lenin[.]biz that sells physical USSR-era Ruble notes bearing the image of Vladimir Lenin, the founding father of the Soviet Union. The Instagram account for Mr. Shefel includes images of stacked USSR-era Ruble notes, as well as multiple links to Shtazi.

Intel 471’s research revealed Ermakov was affiliated in some way with REvil because the stolen Medibank data was published on a blog that had one time been controlled by REvil affiliates who carried out attacks and paid an affiliate fee to the gang.
But by the time of the Medibank hack, the REvil group had mostly scattered after a series of high-profile attacks led to the group being disrupted by law enforcement. In November 2021, Europol announced it arrested seven REvil affiliates who collectively made more than $230 million worth of ransom demands since 2019. At the same time, U.S. authorities unsealed two indictments against a pair of accused REvil cybercriminals.
“The posting of Medibank’s data on that blog, however, indicated a connection with that group, although the connection wasn’t clear at the time,” Intel 471 wrote. “This makes sense in retrospect, as Ermakov’s group had also been a REvil affiliate.”
It is easy to dismiss sanctions like these as ineffective, because as long as Mr. Ermakov remains in Russia he has little to fear of arrest. However, his alleged role as an apparent top member of REvil paints a target on him as someone who likely possesses large sums of cryptocurrency, said Patrick Gray, the Australian co-host and founder of the security news podcast Risky Business.
“I’ve seen a few people poo-poohing the sanctions…but the sanctions component is actually less important than the doxing component,” Gray said. “Because this guy’s life just got a lot more complicated. He’s probably going to have to pay some bribes to stay out of trouble. Every single criminal in Russia now knows he is a vulnerable 33 year old with an absolute ton of bitcoin. So this is not a happy time for him.”
Update, Feb. 21, 1:10 p.m. ET: The Russian security firm F.A.C.C.T reports that Ermakov has been arrested in Russia, and charged with violating domestic laws that prohibit the creation, use and distribution of malicious computer programs.
“During the investigation, several defendants were identified who were not only promoting their ransomware, but also developing custom-made malicious software, creating phishing sites for online stores, and driving user traffic to fraudulent schemes popular in Russia and the CIS,” F.A.C.C.T. wrote. “Among those detained was the owner of the nicknames blade_runner, GistaveDore, GustaveDore, JimJones.”

Google continues to struggle with cybercriminals running malicious ads on its search platform to trick people into downloading booby-trapped copies of popular free software applications. The malicious ads, which appear above organic search results and often precede links to legitimate sources of the same software, can make searching for software on Google a dicey affair.
Google says keeping users safe is a top priority, and that the company has a team of thousands working around the clock to create and enforce their abuse policies. And by most accounts, the threat from bad ads leading to backdoored software has subsided significantly compared to a year ago.
But cybercrooks are constantly figuring out ingenious ways to fly beneath Google’s anti-abuse radar, and new examples of bad ads leading to malware are still too common.
For example, a Google search earlier this week for the free graphic design program FreeCAD produced the following result, which shows that a “Sponsored” ad at the top of the search results is advertising the software available from freecad-us[.]org. Although this website claims to be the official FreeCAD website, that honor belongs to the result directly below — the legitimate freecad.org.
How do we know freecad-us[.]org is malicious? A review at DomainTools.com show this domain is the newest (registered Jan. 19, 2024) of more than 200 domains at the Internet address 93.190.143[.]252 that are confusingly similar to popular software titles, including dashlane-project[.]com, filezillasoft[.]com, keepermanager[.]com, and libreofficeproject[.]com.
Some of the domains at this Netherlands host appear to be little more than software review websites that steal content from established information sources in the IT world, including Gartner, PCWorld, Slashdot and TechRadar.
Other domains at 93.190.143[.]252 do serve actual software downloads, but none of them are likely to be malicious if one visits the sites through direct navigation. If one visits openai-project[.]org and downloads a copy of the popular Windows desktop management application Rainmeter, for example, the file that is downloaded has the same exact file signature as the real Rainmeter installer available from rainmeter.net.
But this is only a ruse, says Tom Hegel, principal threat researcher at the security firm Sentinel One. Hegel has been tracking these malicious domains for more than a year, and he said the seemingly benign software download sites will periodically turn evil, swapping out legitimate copies of popular software titles with backdoored versions that will allow cybercriminals to remotely commander the systems.
“They’re using automation to pull in fake content, and they’re rotating in and out of hosting malware,” Hegel said, noting that the malicious downloads may only be offered to visitors who come from specific geographic locations, like the United States. “In the malicious ad campaigns we’ve seen tied to this group, they would wait until the domains gain legitimacy on the search engines, and then flip the page for a day or so and then flip back.”
In February 2023, Hegel co-authored a report on this same network, which Sentinel One has dubbed MalVirt (a play on “malvertising”). They concluded that the surge in malicious ads spoofing various software products was directly responsible for a surge in malware infections from infostealer trojans like IcedID, Redline Stealer, Formbook and AuroraStealer.
Hegel noted that the spike in malicious software-themed ads came not long after Microsoft started blocking by default Office macros in documents downloaded from the Internet. He said the volume of the current malicious ad campaigns from this group appears to be relatively low compared to a year ago.
“It appears to be same campaign continuing,” Hegel said. “Last January, every Google search for ‘Autocad’ led to something bad. Now, it’s like they’re paying Google to get one out of every dozen of searches. My guess it’s still continuing because of the up-and-down [of the] domains hosting malware and then looking legitimate.”
Several of the websites at this Netherlands host (93.190.143[.]252) are currently blocked by Google’s Safebrowsing technology, and labeled with a conspicuous red warning saying the website will try to foist malware on visitors who ignore the warning and continue.
But it remains a mystery why Google has not similarly blocked more than 240+ other domains at this same host, or else removed them from its search index entirely. Especially considering there is nothing else but these domains hosted at that Netherlands IP address, and because they have all remained at that address for the past year.
In response to questions from KrebsOnSecurity, Google said maintaining a safe ads ecosystem and keeping malware off of its platforms is a priority across Google.
“Bad actors often employ sophisticated measures to conceal their identities and evade our policies and enforcement, sometimes showing Google one thing and users something else,” Google said in a written statement. “We’ve reviewed the ads in question, removed those that violated our policies, and suspended the associated accounts. We’ll continue to monitor and apply our protections.”
Google says it removed 5.2 billion ads in 2022, and restricted more than 4.3 billion ads and suspended over 6.7 million advertiser accounts. The company’s latest ad safety report says Google in 2022 blocked or removed 1.36 billion advertisements for violating its abuse policies.
Some of the domains referenced in this story were included in Sentinel One’s February 2023 report, but dozens more have been added since, such as those spoofing the official download sites for Corel Draw, Github Desktop, Roboform and Teamviewer.
This October 2023 report on the FreeCAD user forum came from a user who reported downloading a copy of the software from freecadsoft[.]com after seeing the site promoted at the top of a Google search result for “freecad.” Almost a month later, another FreeCAD user reported getting stung by the same scam.
“This got me,” FreeCAD forum user “Matterform” wrote on Nov. 19, 2023. “Please leave a report with Google so it can flag it. They paid Google for sponsored posts.”
Sentinel One’s report didn’t delve into the “who” behind this ongoing MalVirt campaign, and there are precious few clues that point to attribution. All of the domains in question were registered through webnic.cc, and several of them display a placeholder page saying the site is ready for content. Viewing the HTML source of these placeholder pages shows many of the hidden comments in the code are in Cyrillic.
Trying to track the crooks using Google’s Ad Transparency tools didn’t lead far. The ad transparency record for the malicious ad featuring freecad-us[.]org (in the screenshot above) shows that the advertising account used to pay for the ad has only run one previous ad through Google search: It advertised a wedding photography website in New Zealand.
The apparent owner of that photography website did not respond to requests for comment, but it’s also likely his Google advertising account was hacked and used to run these malicious ads.
