The sufferer shaming web site operated by the Snatch ransomware group is leaking knowledge about its true on-line location and inside operations, in addition to the Web addresses of its guests, KrebsOnSecurity has discovered. The leaked knowledge counsel that Snatch is one in every of a number of ransomware teams utilizing paid advertisements on Google.com to trick individuals into putting in malware disguised as in style free software program, corresponding to Microsoft Groups, Adobe Reader, Mozilla Thunderbird, and Discord.
First noticed in 2018, the Snatch ransomware group has revealed knowledge stolen from a whole lot of organizations that refused to pay a ransom demand. Snatch publishes its stolen knowledge at a web site on the open Web, and that content material is mirrored on the Snatch workforce’s darknet web site, which is simply reachable utilizing the worldwide anonymity community Tor.
The sufferer shaming web site for the Snatch ransomware gang.
KrebsOnSecurity has discovered that Snatch’s darknet web site 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 reveals that the Snatch darknet web site generates a good quantity of site visitors, typically attracting 1000’s of holiday makers every day. However by far probably the most frequent repeat guests are coming from Web addresses in Russia that both presently host Snatch’s clear internet domains or not too long ago did.
The Snatch ransomware gang’s sufferer shaming web site on the darknet is leaking knowledge about its guests. This “server standing” web page says that Snatch’s web site is on Central European Summer time Time (CEST) and is powered by OpenSSL/1.1.1f, which is not supported by safety updates.
Most likely probably the most lively Web handle accessing Snatch’s darknet web site is 193.108.114[.]41, which is a server in Yekaterinburg, Russia that hosts a number of Snatch domains, together with snatchteam[.]high, sntech2ch[.]high, dwhyj2[.]high and sn76930193ch[.]high. It may nicely be that this Web handle is exhibiting up ceaselessly as a result of Snatch’s clear-web web site encompasses a toggle button on the high that lets guests swap over to accessing the positioning by way of Tor.
One other Web handle that confirmed up ceaselessly within the Snatch server standing web page was 194.168.175[.]226, presently assigned to Matrix Telekom in Russia. Based on DomainTools.com, this handle additionally hosts or else not too long ago hosted the same old coterie of Snatch domains, in addition to fairly a number of domains phishing identified manufacturers corresponding to Amazon and Cashapp.
The Moscow Web handle 80.66.64[.]15 accessed the Snatch darknet web site all day lengthy, and that handle additionally housed the suitable Snatch clear-web domains. Extra curiously, that handle is residence to a number of current domains that seem confusingly much like identified software program corporations, together with libreoff1ce[.]com and www-discord[.]com.
That is fascinating as a result of the phishing domains related to the Snatch ransomware gang had been all registered to the identical Russian title — Mihail Kolesnikov, a reputation that’s considerably synonymous with current phishing domains tied to malicious Google advertisements.
Kolesnikov might be a nod to a Russian common made well-known throughout Boris Yeltsin’s reign. Both manner, it’s clearly a pseudonym, however there are another commonalities amongst these domains that 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 companies 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 “.high” and “.app” that seem designed to imitate the domains of main software program corporations, together with www-citrix[.]high, www-microsofteams[.]high, www-fortinet[.]high, ibreoffice[.]high, www-docker[.]high, www-basecamp[.]high, ccleaner-cdn[.]high, adobeusa[.]high, and www.real-vnc[.]high.
In August 2023, researchers with Trustwave Spiderlabs stated they encountered domains registered to Mihail Kolesnikov getting used to disseminate the Rilide info stealer trojan.
Nevertheless it seems a number of crime teams could also be utilizing these domains to phish individuals and disseminate all types of information-stealing malware. In February 2023, Spamhaus warned of an enormous surge in malicious advertisements that had been hijacking search ends in Google.com, and getting used to distribute at the very least 5 totally different households of data stealing trojans, together with AuroraStealer, IcedID/Bokbot, Meta Stealer, RedLine Stealer and Vidar.
For instance, Spamhaus stated victims of those malicious advertisements 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 end result — above all different outcomes. The malicious advert would come with a brand for Microsoft and at first look look like a secure and trusted place to obtain the Microsoft Groups shopper.
Nonetheless, anybody who clicked on the end result was whisked away as a substitute to mlcrosofteams-us[.]high — one more malicious area registered to Mr. Kolesnikov. And whereas guests to this web site might consider they’re solely downloading the Microsoft Groups shopper, the installer file features a copy of the IcedID malware, which is admittedly good at stealing passwords and authentication tokens from the sufferer’s internet browser.
Picture: Spamhaus
The founding father of the Swiss anti-abuse web site abuse.ch instructed Spamhaus it’s seemingly that some cybercriminals have began to promote “malvertising as a service” on the darkish internet, and that there’s a substantial 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 knowledge (and any company entry) to lively and hungry ransomware group associates.
The tip in regards to the uncovered “server standing” web page on the Snatch darkweb web site got here from @htmalgae, the identical safety researcher who alerted KrebsOnSecurity earlier this month that the darknet sufferer shaming web site run by the 8Base ransomware gang was inadvertently left in improvement mode.
That oversight revealed not solely the true Web handle of the hidden 8Base web site (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 web site leaking knowledge that they didn’t intend to reveal is deliciously ironic.
“It is a legal group that shames others for not defending consumer knowledge,” @htmalgae stated. “And right here they’re leaking their consumer knowledge.”
All the malware talked about on this story is designed to run on Microsoft Home windows units. However Malwarebytes not too long ago lined the emergence of a Mac-based info stealer trojan referred to as AtomicStealer that was being marketed by means of malicious Google advertisements and domains that had been confusingly much like software program manufacturers.
Please be additional cautious if you find yourself looking on-line for in style software program titles. Cracked, pirated copies of main software program titles are a frequent supply of infostealer infections, as are these rogue advertisements masquerading as search outcomes. Ensure to double-check you might be truly on the area you consider you’re visiting *earlier than* you obtain and set up something.
Keep tuned for Half II of this submit, which features a nearer have a look at the Snatch ransomware group and their founder.
