The sufferer shaming website operated by the Snatch ransomware group is leaking information about its true on-line location and inner operations, in addition to the Web addresses of its guests, KrebsOnSecurity has discovered. The leaked information recommend that Snatch is one among a number of ransomware teams utilizing paid adverts on Google.com to trick folks into putting in malware disguised as fashionable free software program, akin to Microsoft Groups, Adobe Reader, Mozilla Thunderbird, and Discord.
First noticed in 2018, the Snatch ransomware group has revealed information stolen from lots of of organizations that refused to pay a ransom demand. Snatch publishes its stolen information at a web site on the open Web, and that content material is mirrored on the Snatch workforce’s darknet website, which is barely reachable utilizing the worldwide anonymity community Tor.
KrebsOnSecurity has realized that Snatch’s darknet website exposes its “server standing” web page, which incorporates details about the true Web addresses of customers accessing the web site.
Refreshing this web page each few seconds exhibits that the Snatch darknet website generates a good quantity of visitors, typically attracting hundreds of tourists every day. However by far essentially the most frequent repeat guests are coming from Web addresses in Russia that both presently host Snatch’s clear net domains or lately did.
Most likely essentially the most lively Web deal with accessing Snatch’s darknet website is 193.108.114[.]41, which is a server in Yekaterinburg, Russia that hosts a number of Snatch domains, together with snatchteam[.]prime, sntech2ch[.]prime, dwhyj2[.]prime and sn76930193ch[.]prime. It might properly be that this Web deal with is exhibiting up steadily as a result of Snatch’s clear-web website encompasses a toggle button on the prime that lets guests swap over to accessing the positioning through Tor.
One other Web deal with that confirmed up steadily within the Snatch server standing web page was 194.168.175[.]226, presently assigned to Matrix Telekom in Russia. In keeping with DomainTools.com, this deal with additionally hosts or else lately hosted the same old coterie of Snatch domains, in addition to fairly a number of domains phishing identified manufacturers akin to Amazon and Cashapp.
The Moscow Web deal with 80.66.64[.]15 accessed the Snatch darknet website all day lengthy, and that deal with additionally housed the suitable Snatch clear-web domains. Extra apparently, that deal with is dwelling to a number of current domains that seem confusingly much like identified software program firms, together with libreoff1ce[.]com and www-discord[.]com.
That is attention-grabbing as a result of the phishing domains related to the Snatch ransomware gang have been all registered to the identical Russian identify — Mihail Kolesnikov, a reputation that’s considerably synonymous with current phishing domains tied to malicious Google adverts.
Kolesnikov might be a nod to a Russian common made well-known throughout Boris Yeltsin’s reign. Both method, it’s clearly a pseudonym, however there are another commonalities amongst these domains which will present perception into how Snatch and different ransomware teams are sourcing their victims.
DomainTools says there are greater than 1,300 present and former domains registered to Mihail Kolesnikov between 2013 and July 2023. About half of the domains look like older web sites promoting feminine escort providers in main cities round the US (e.g. the now-defunct pittsburghcitygirls[.]com).
The opposite half of the Kolesnikov web sites are far newer phishing domains largely ending in “.prime” and “.app” that seem designed to imitate the domains of main software program firms, together with www-citrix[.]prime, www-microsofteams[.]prime, www-fortinet[.]prime, ibreoffice[.]prime, www-docker[.]prime, www-basecamp[.]prime, ccleaner-cdn[.]prime, adobeusa[.]prime, and www.real-vnc[.]prime.
However it seems a number of crime teams could also be utilizing these domains to phish folks and disseminate every kind of information-stealing malware. In February 2023, Spamhaus warned of an enormous surge in malicious adverts that have been hijacking search ends in Google.com, and getting used to distribute at the least 5 totally different households of knowledge stealing trojans, together with AuroraStealer, IcedID/Bokbot, Meta Stealer, RedLine Stealer and Vidar.
For instance, Spamhaus stated victims of those malicious adverts would seek for Microsoft Groups in Google.com, and the search engine would typically return a paid advert spoofing Microsoft or Microsoft Groups as the primary consequence — above all different outcomes. The malicious advert would come with a emblem for Microsoft and at first look look like a protected and trusted place to obtain the Microsoft Groups shopper.
Nevertheless, anybody who clicked on the consequence was whisked away as a substitute to mlcrosofteams-us[.]prime — yet one more malicious area registered to Mr. Kolesnikov. And whereas guests to this web site might imagine they’re solely downloading the Microsoft Groups shopper, the installer file features a copy of the IcedID malware, which is basically good at stealing passwords and authentication tokens from the sufferer’s net browser.
The founding father of the Swiss anti-abuse web site abuse.ch advised Spamhaus it’s probably that some cybercriminals have began to promote “malvertising as a service” on the darkish net, and that there’s an excessive amount of demand for this service.
In different phrases, somebody seems to have constructed a really worthwhile enterprise churning out and selling new software-themed phishing domains and promoting that as a service to different cybercriminals. Or maybe they’re merely promoting any stolen information (and any company entry) to lively and hungry ransomware group associates.
The tip concerning the uncovered “server standing” web page on the Snatch darkweb website got here from @htmalgae, the identical safety researcher who alerted KrebsOnSecurity earlier this month that the darknet sufferer shaming website run by the 8Base ransomware gang was inadvertently left in improvement mode.
That oversight revealed not solely the true Web deal with of the hidden 8Base website (in Russia, naturally), but additionally the identification of a programmer in Moldova who apparently helped to develop the 8Base code.
@htmalgae stated the thought of a ransomware group’s sufferer shaming website leaking information that they didn’t intend to show is deliciously ironic.
“It is a prison group that shames others for not defending consumer information,” @htmalgae stated. “And right here they’re leaking their consumer information.”
The entire malware talked about on this story is designed to run on Microsoft Home windows gadgets. However Malwarebytes lately lined the emergence of a Mac-based data stealer trojan known as AtomicStealer that was being marketed via malicious Google adverts and domains that have been confusingly much like software program manufacturers.
Please be additional cautious when you’re looking out on-line for fashionable software program titles. Cracked, pirated copies of main software program titles are a frequent supply of infostealer infections, as are these rogue adverts masquerading as search outcomes. Be certain to double-check you might be really on the area you imagine you’re visiting *earlier than* you obtain and set up something.
Keep tuned for Half II of this publish, which features a nearer have a look at the Snatch ransomware group and their founder.
