On this publish we’ll have a look at the clues left behind by “Babam,” the deal with chosen by a cybercriminal who has bought such entry to ransomware teams on many events over the previous few years.

For the reason that starting of 2020, Babam has arrange quite a few auctions on the Russian-language cybercrime discussion board Exploit, primarily promoting digital personal networking (VPN) credentials stolen from numerous corporations.

All of those domains date again to between 2012 and 2013.

The unique registration information for the iPhone, Sagepay and Gold domains share an e-mail tackle: devrian26@gmail.com. A search on the username “bo3dom” utilizing Constella’s service reveals an account at ipmart-forum.com, a now-defunct discussion board involved with IT merchandise, equivalent to cell gadgets, computer systems and on-line gaming. That search reveals the person bo3dom registered at ipmart-forum.com with the e-mail tackle devrian27@gmail.com, and from an Web tackle in Vilnius, Lithuania.

Devrian27@gmail.com was used to register a number of domains, together with wwwsuperchange.ru again in 2008 (discover once more the suspect “www” as a part of the area identify). Gmail’s password restoration perform says the backup e-mail tackle for devrian27@gmail.com is bo3*******@gmail.com. Gmail accepts the tackle bo3domster@gmail.com because the restoration e-mail for that devrian27 account.

In accordance with Constella, the bo3domster@gmail.com tackle was uncovered in a number of knowledge breaches over time, and in every case it used one among two passwords: “lebeda1” and “a123456“.

Looking out in Constella for accounts utilizing these passwords reveals a slew of further “bo3dom” e-mail addresses, together with bo3dom@gmail.com.  Pivoting on that tackle in Constella reveals that somebody with the identify Vytautas Mockus used it to register an account at mindjolt.com, a website that includes dozens of easy puzzle video games that guests can play on-line.

In some unspecified time in the future, mindjolt.com apparently additionally was hacked, as a result of a replica of its database at Constella says the bo3dom@gmail.com used two passwords at that website: lebeda1 and a123456.

A reverse WHOIS search on “Vytautas Mockus” at DomainTools reveals the e-mail tackle devrian25@gmail.com was utilized in 2010 to register the area identify perfectmoney[.]co. That is one character off of perfectmoney[.]com, which is an early digital foreign money that was fairly fashionable with cybercriminals on the time. The telephone quantity tied to that area registration was “86.7273687“.

A Google seek for “Vytautas Mockus” says there’s an individual by that identify who runs a cell meals service firm in Lithuania known as “Palvisa.” A report on Palvisa (PDF) bought from Rekvizitai.vz — an official on-line listing of Lithuanian corporations — says Palvisa was established in 2011 by a Vytautaus Mockus, utilizing the telephone quantity 86.7273687, and the e-mail tackle bo3dom@gmail.com.

The domains apparently registered by Babam over practically 10 years counsel he began off primarily stealing from different cybercrooks. By 2015, Babam was closely into “carding,” the sale and use of stolen fee card knowledge. By 2020, he’d shifted his focus virtually solely to promoting entry to corporations.

A profile produced by risk intelligence agency Flashpoint says Babam has obtained a minimum of 4 constructive suggestions evaluations on the Exploit cybercrime discussion board from crooks related to the LockBit ransomware gang.

In accordance with Flashpoint, in April 2021 Babam marketed the sale of Citrix credentials for a global firm that’s lively within the discipline of laboratory testing, inspection and certification, and that has greater than $5 billion in annual revenues and greater than 78,000 staff.

Flashpoint says Babam initially introduced he’d bought the entry, however later reopened the public sale as a result of the potential purchaser backed out of the deal. A number of days later, Babam reposted the public sale, including extra details about the depth of the illicit entry and decreasing his asking value. The entry bought lower than 24 hours later.

“Based mostly on the offered statistics and delicate supply reporting, Flashpoint analysts assess with excessive confidence that the compromised group was seemingly Bureau Veritas, a company headquartered in France that operates in a wide range of sectors,” the corporate concluded.

In November, Bureau Veritas acknowledged that it shut down its community in response to a cyber assault. The corporate hasn’t mentioned whether or not the incident concerned ransomware and if that’s the case what pressure of ransomware, however its response to the incident is straight out of the playbook for responding to ransomware assaults. Bureau Veritas has not but responded to requests for remark; its newest public assertion on Dec. 2 offers no further particulars about the reason for the incident.

Flashpoint notes that Babam’s use of transliterated Russian persists on each Exploit and Verified till round March 2020, when he switches over to utilizing largely Cyrillc in his discussion board feedback and gross sales threads. Flashpoint mentioned this could possibly be a sign {that a} totally different particular person began utilizing the Babam account since then, or extra seemingly that Babam had solely a tenuous grasp of Russian to start with and that his language abilities and confidence improved over time.

Lending credence to the latter principle is that Babam nonetheless makes linguistic errors in his postings that counsel Russian is just not his unique language, Flashpoint discovered.

“Using double “n” in such phrases as “проданно” (appropriate – продано) and “сделанны” (appropriate – сделаны) by the risk actor proves that this fashion of writing is just not potential when utilizing machine translation since this might not be the right spelling of the phrase,” Flashpoint analysts wrote.

“A majority of these grammatical errors are sometimes discovered amongst individuals who didn’t obtain ample training in school or if Russian is their second language,” the evaluation continues. “In such circumstances, when somebody tries to spell a phrase appropriately, then accidentally or unknowingly, they overdo the spelling and make all these errors. On the similar time, colloquial speech will be fluent and even native. That is typically typical for an individual who comes from the previous Soviet Union states.”
