Ransomware teams periodically disappear, solely to reinvent themselves beneath new branding.

Different prospects embrace interdiction by law enforcement – US authorities have proven themselves extra keen to actively dismantle cybercrime infrastructure of late – and even interference from rival cybercrime gangs.

Laying low?

The Sodinokibi ransomware, broadly attributed to the REvil gang and distributed by associates by a Ransomware-as-a-Service (RaaS) enterprise mannequin, has been a scourge of company safety over the past two years or extra.

The group’s malware-fuelled cybercrime exercise has intensified of late with the Kaseya provide chain assault, and it may very well be that the REvil crew have stepped again with a view to permit issues to chill off.

BACKGROUND What is Sodinokibi? The ransomware behind the Travelex attack

The success of REvil in making hundreds of thousands of {dollars} signifies that a return in some kind is maybe the more than likely situation.

Oleg Skulkin, a lead digital forensics analyst at safety agency Group-IB, commented:

REvil have both determined to close down their infrastructure themselves to then begin from scratch and proceed working beneath a brand new identify with up to date instruments (as it’s was the case with Ako ransomware that then advanced to Ranzy) or, in one other situation, REvil infrastructure might need gone down because of a regulation enforcement operation.

Police motion

REvil’s accounts on hacker boards have been blocked by the administration, in line with Group-IB, as a precaution in opposition to regulation enforcement motion on the discussion board. This disavowal suggests the denizens of the darkish internet assume the authorities might need intervened.

“The doable police motion in opposition to REvil isn’t prone to turn out to be an enormous drawback for his or her associates for the reason that latter bounce from one ransomware-as-a-service program to a different, and even work with a number of RaaS [suppliers] on the identical time,” Skulkin explaine

Vladimir Kuskov, head of menace exploration at antivirus vendor Kaspersky, added that recognized REvil representatives have been banned from a darknet cybercrime discussion board.

“Assets associated to REvil, which included a weblog with details about their assaults, in addition to fee websites, went offline,” Kuskov stated.

“A consultant of this group was additionally banned from a well-liked darknet discussion board the place individuals of this felony business talk.”

The safety professional added: “Why the web sites went down isn’t but clear, nonetheless, circumstances recommend that REvil may cease its operations, following the trail DarkSide, Avaddon, and Babuk took.”

Political stress

REvil is a Russian-speaking RaaS operation that’s regarded as based mostly in Russia. The group avoids concentrating on Russian establishments by way of system language detection that’s constructed into the malware code.

The US has threatened retaliation in opposition to Russia within the wake of the Kaseya assault and this may very well be an element within the shutdown.

“My guess is that it was political stress, from the US to Russia and Russia to them,” in line with BlackBerry menace researcher Eric Milam, who has earlier accomplished in depth analysis into the menace actors.

Milam informed The Day by day Swig: “When the highlight is on a felony group, they might select to step away for some time.

“They typically use this time to make a ‘higher product’ and are available again later. This isn’t not like firms that begin to get a foul fame, they have a tendency to rebrand themselves and are available again as one thing ‘completely different’, even when it’s simply their identify.”

Some proof means that REvil sprang from the ashes of GandCrab, an earlier and now defunct ransomware operation.

Milam and his colleagues are effectively positioned to attribute additional assaults to these behind REvil, ought to the gang return.

“Our crew would focus primarily on the laborious proof of any new variants,” Miam defined. “That would come with issues like fingerprinting the file/code, the modes of operation, location of assaults, and so forth. Most attackers gained’t actually change their core methods.”
