Earlier this week, KrebsOnSecurity revealed that the darknet web site for the Snatch ransomware group was leaking knowledge about its customers and the crime gang’s inside operations. In the present day, we’ll take a more in-depth take a look at the historical past of Snatch, its alleged founder, and their claims that everybody has confused them with a special, older ransomware group by the identical title.
In line with a September 20, 2023 joint advisory from the FBI and the U.S. Cybersecurity and Infrastructure Safety Administration (CISA), Snatch was initially named Workforce Truniger, based mostly on the nickname of the group’s founder and organizer — Truniger.
The FBI/CISA report says Truniger beforehand operated as an affiliate of GandCrab, an early ransomware-as-a-service providing that closed up store after a number of years and claims to have extorted more than $2 billion from victims. GandCrab dissolved in July 2019, and is believed to have develop into “REvil,” one of the vital ruthless and rapacious Russian ransomware teams of all time.
The federal government says Snatch used a personalized ransomware variant notable for rebooting Microsoft Home windows gadgets into Protected Mode — enabling the ransomware to avoid detection by antivirus or endpoint safety — after which encrypting recordsdata when few providers are working.
“Snatch risk actors have been noticed buying beforehand stolen knowledge from different ransomware variants in an try and additional exploit victims into paying a ransom to keep away from having their knowledge launched on Snatch’s extortion weblog,” the FBI/CISA alert reads. It continues:
“Previous to deploying the ransomware, Snatch risk actors had been noticed spending as much as three months on a sufferer’s system. Inside this timeframe, Snatch risk actors exploited the sufferer’s community shifting laterally throughout the sufferer’s community with RDP for the biggest potential deployment of ransomware and looking for recordsdata and folders for knowledge exfiltration adopted by file encryption.”
New York Metropolis-based cyber intelligence agency Flashpoint stated the Snatch ransomware group was created in 2018, based mostly on Truniger’s recruitment each on Russian language cybercrime boards and public Russian programming boards. Flashpoint stated Truniger recruited “pen testers” for a brand new, then-unnamed cybercrime group, by posting their non-public Jabber prompt messenger contact particulars on a number of Russian language coding boards, in addition to on Fb.
“The command requires Home windows system directors,” Truniger’s advertisements defined. “Expertise in backup, improve privileges, mikicatz, community. Particulars after contacting on jabber: truniger@xmpp[.]jp.”
In not less than a few of these recruitment advertisements — like one in 2018 on the discussion board sysadmins[.]ru –the username selling Truniger’s contact data was Semen7907. In April 2020, Truniger was banned from two of the highest Russian cybercrime boards, the place members from each boards confirmed that Semen7907 was one in all Truniger’s recognized aliases.
[SIDE NOTE: Truniger was banned because he purchased credentials to a company from a network access broker on the dark web, and although he promised to share a certain percentage of whatever ransom amount Truniger’s group extracted from the victim, Truniger paid the access broker just a few hundred dollars off of a six-figure ransom].
In line with Constella Intelligence, an information breach and risk actor analysis platform, a person named Semen7907 registered in 2017 on the Russian-language programming discussion board pawno[.]ru utilizing the e-mail deal with [email protected].
That very same e-mail deal with was assigned to the person “Semen-7907” on the now defunct gaming web site tunngle.internet, which suffered an information breach in 2020. Semen-7907 registered at Tunngle from the Web deal with 31.192.175[.]63, which is in Yekaterinburg, RU.
Constella stories that [email protected] was additionally used to register an account on the on-line sport stalker[.]so with the nickname Trojan7907.
There’s a Skype person by the deal with semen7907, and which has the title Semyon Tretyakov from Yekaterinburg, RU. Constella additionally discovered a breached report from the Russian cell telephony web site tele2[.]ru, which reveals {that a} person from Yekaterinburg registered in 2019 with the title Semyon Sergeyvich Tretyakov and e-mail deal with [email protected].
The above accounts, in addition to the e-mail deal with [email protected], had been all registered or accessed from the identical Yekaterinburg Web deal with talked about beforehand: 31.192.175.63. The Russian cell phone quantity related to that tele2[.]ru account is linked to the Telegram account “Perchatka,” (“glove” in Russian).
BAD BEATS
Reached by way of Telegram, Perchatka (a.okay.a. Mr. Tretyakov) stated he was not a cybercriminal, and that he at present has a full-time job working in IT at a serious firm (he declined to specify which).
Introduced with the knowledge gathered for this report (and extra that’s not printed right here), Mr. Tretyakov acknowledged that Semen7907 was his account on sysadmins[.]ru, the exact same account Truniger used to recruit hackers for the Snatch Ransomware group again in 2018.
Nonetheless, he claims that he by no means made these posts, and that another person should have assumed management over his sysadmins[.]ru account and posted as him. Mr. Tretyakov stated that KrebsOnSecurity’s outreach this week was the primary time he turned conscious that his sysadmins[.]ru account was used with out his permission.
Mr. Tretyakov steered somebody could have framed him, pointing to an August 2023 story at a Russian information outlet in regards to the reported hack and leak of the person database from sysadmins[.]ru, allegedly by the hands of a pro-Ukrainian hacker group known as CyberSec.
“Lately, due to the conflict in Ukraine, an enormous variety of databases have been leaked and discovering details about an individual just isn’t troublesome,” Tretyakov stated. “I’ve been utilizing this login since about 2013 on all of the boards the place I register, and I don’t at all times set a powerful password. If I had achieved one thing unlawful, I might have hidden significantly better :D.”
[For the record, KrebsOnSecurity does not generally find this to be the case, as the ongoing Breadcrumbs series will attest.]
A Semyon Sergeyvich Tretyakov is listed because the composer of a Russian-language rap track known as “Parallels,” which appears to be in regards to the pursuit of a high-risk way of life on-line. A snippet of the track goes:
“Somebody is on the display screen, somebody is on the blacklist
I activate the timer and calculate the dangers
I don’t wish to keep broke And within the pursuit of cash
I can’t take these zeros Life is sort of a zebra –
everybody needs to be first Both the stripes are white,
or we’re shifting via the wilds I gained’t waste time.”
Mr. Tretyakov stated he was not the writer of that individual rhyme, however that he has been recognized to report his personal rhythms.
“Typically I make dangerous beats,” he stated. “Soundcloud.”
NEVER MIND THE DOMAIN NAME
The FBI/CISA alert on Snatch Ransomware (PDF) contains an fascinating caveat: It says Snatch really deploys ransomware on sufferer programs, but it surely additionally acknowledges that the present occupants of Snatch’s darkish and clear net domains name themselves Snatch Workforce, and keep that they aren’t the identical folks as Snatch Ransomware from 2018.
Right here’s the fascinating bit from the FBI/CISA report:
“Since November 2021, an extortion web site working below the title Snatch served as a clearinghouse for knowledge exfiltrated or stolen from sufferer firms on Clearnet and TOR hosted by a bulletproof internet hosting service. In August 2023, people claiming to be related to the weblog gave a media interview claiming the weblog was not related to Snatch ransomware and “none of our targets has been attacked by Ransomware Snatch…”, regardless of a number of confirmed Snatch victims’ knowledge showing on the weblog alongside victims related to different ransomware teams, notably Nokoyawa and Conti.”
Avid readers will recall a narrative right here earlier this week about Snatch Workforce’s leaky darknet website based mostly in Yekaterinburg, RU that uncovered their inside operations and Web addresses of their guests. The leaked knowledge counsel that Snatch is one in all a number of ransomware teams utilizing paid advertisements on Google.com to trick folks into putting in malware disguised as widespread free software program, equivalent to Microsoft Groups, Adobe Reader, Mozilla Thunderbird, and Discord.
Snatch Workforce claims to deal solely in stolen knowledge — not in deploying ransomware malware to carry programs hostage.
Representatives of the Snatch Workforce just lately answered questions from Databreaches.internet in regards to the claimed discrepancy within the FBI/CISA report.
“Initially, we repeat as soon as once more that we’ve got nothing to do with Snatch Ransomware, we’re Safety Notification Attachment, and we’ve got by no means violated the phrases of the concluded transactions, as a result of our honesty and openness is the assure of our revenue,” the Snatch Workforce wrote to Databreaches.internet in response to questions.
However thus far the Snatch Workforce has not been in a position to clarify why it’s utilizing the exact same domains that the Snatch ransomware group used?
Their declare is much more unbelievable as a result of the Snatch Workforce members instructed Databreaches.internet they didn’t even know {that a} ransomware group with that title already existed after they initially shaped simply two years in the past.
That is troublesome to swallow as a result of even when they had been a separate group, they’d nonetheless have to in some way coordinate the switch of the Ransomware group’s domains on the clear and darkish webs. In the event that they had been hoping for a recent begin or separation, why not simply choose a brand new title and new net vacation spot?
“Snatchteam[.]cc is basically an information market,” they continued. “The one factor to underline is that we’re towards promoting leaked data, sticking to the concept of free entry. Completely any group can come to us and supply data for publication. Much more, we’ve got heard rumors that numerous ransomware groups scare their purchasers that they are going to submit leaked data on our useful resource. We wouldn’t have our personal ransomware, however we’re open to cooperation on placement and monetization of dates (sic).”
Possibly Snatch Workforce doesn’t want to be related to Snatch Ransomware as a result of they at present consider stealing knowledge after which extorting sufferer firms for cash is in some way much less evil than infecting the entire sufferer’s servers and backups with ransomware.
Additionally it is doubtless that Snatch Workforce is properly conscious of how poorly a few of their founders lined their tracks on-line, and are hoping for a do-over on that entrance.
