Karakurt information thieves linked to bigger Conti hacking group

Posted on

An evaluation of the cryptocurrency wallets tied to the Karakurt hacker group, mixed with their explicit methodology for information theft, means that the group’s membership overlaps with two different outstanding hacking crews, in line with an evaluation printed by cybersecurity agency Tetra Protection.

Tetra’s report particulars the expertise of a shopper firm that was hit with a ransomware assault by the Conti group, and subsequently focused once more by an information theft perpetrated by the Karakurt group. The evaluation confirmed that the Karakurt assault used exactly the identical backdoor to compromise the shopper’s methods as the sooner Conti assault.

“Such entry may solely be obtained by way of some type of buy, relationship, or surreptitiously getting access to Conti group infrastructure,” Tetra wrote in its report.

It is vital to distinguish the 2 various kinds of cyberattack described right here, in line with Tetra. In a ransomware assault, key information is encrypted and the extortion cash is paid in trade for a decryption key, in order that the goal firm can recuperate its information and resume working. In an information theft, which has been the only real sort of assault perpetrated by the Karakurt group, hackers steal delicate company information and demand cash in trade for not releasing it to the world at massive.

The Karakurt assaults of this sort — there have been greater than a dozen up to now, in line with Tetra — additionally used cryptocurrency wallets linked to Conti sufferer fee addresses, additional strengthening the argument that the 2 teams’ membership might overlap considerably.

This sample represents a departure from the Conti group’s regular sample of enterprise, in line with Nathan Little, senior vp of digital forensics and incident response at Tetra,

“Traditionally, we have seen the criminals honor their offers,” he says. “Early on, when these [data theft attacks] began in 2019, it was frequent that firms have been frightened sufficient that they’d pay, to not conceal the incident, however to keep away from the implications.”

As of late, nonetheless, information theft has grow to be frequent sufficient — and new regulatory regimes have made obligatory disclosures extra probably — that firms are much less more likely to pay simply to have their information protected.

Neither is that that the one complicated factor in regards to the Karakurt assaults, in line with Tetra. The assaults erode belief amongst sufferer firms that they will not be focused a number of instances by the identical kinds of assaults. Paying off a Conti ransom was often a comparatively stable assure that the group would transfer on and that no additional assaults can be forthcoming. If the 2 teams are linked, and victims are not directly being re-extorted by the identical folks, funds might grow to be tougher to return by.

‘It is fascinating the way it unfolds,” says Little. “It does appear to be a bit little bit of a facet hustle throughout the Conti group.”

Whereas the equipment of cybercrime is fantastically sophisticated, he added, the preliminary system compromise that makes these assaults potential is incessantly fairly easy, and might usually be prevented with comparatively fundamental protecting measures.

“Cybersecurity is a giant downside that wants fixing, however many of those incidents, with some fairly fundamental cybersecurity controls, they would not occur,” Little says.
