REvil Ransomware Gang Mysteriously Disappears After High-Profile Attacks

REvil, the notorious ransomware cartel driving some of the most important cyberattacks targeting JBS and Kaseya, has mysteriously disappeared from the darkish web, major to speculations that the legal business might have been taken down.

Numerous darknet and clearnet web sites preserved by the Russia-linked cybercrime syndicate, like the knowledge leak, extortion, and payment portals, remained inaccessible, exhibiting an error message “Onionsite not uncovered.”

The group’s Tor community infrastructure on the dark net is made up of 1 info leak web site web page and 22 data internet hosting web-sites. It is really not straight away obvious what prompted the infrastructure to be knocked offline.

REvil is a person of the most prolific ransomware-as-a-support (RaaS) teams that very first appeared on the menace landscape in April 2019. It’s an evolution of the GandCrab ransomware, which strike the underground marketplaces in early 2018.

“If REvil has been completely disrupted, it’ll mark the end of a team which has been dependable for >360 assaults on the U.S. public and non-public sectors this 12 months by yourself,” Emsisoft’s Brett Callow tweeted.

The sudden enhancement comes near on the heels of a vast-scale supply chain ransomware attack aimed at engineering companies provider Kaseya, for which REvil (aka Sodinokibi) took duty for and demanded a $70 million ransom to unlock entry to encrypted devices in exchange for a common decryption crucial that would unlock all victims knowledge.

The disastrous assault noticed the ransomware gang encrypting approximately 60 managed provider vendors (MSPs) and more than 1,500 downstream corporations applying a zero-working day vulnerability in the Kaseya VSA remote administration program. In late May perhaps, REvil also masterminded the assault on the world’s largest meat producer JBS, which finished up shelling out $11 million to the extortionists to get well from the incident.

The outage also coincides with U.S. President Joe Biden’s telephone contact with Russian President Vladimir Putin past 7 days, urgent the latter to take steps to disrupt ransomware groups functioning in the nation, although warning of retaliatory action to protect crucial infrastructure.

“The predicament is still unfolding, but proof indicates REvil has suffered a planned, concurrent takedown of their infrastructure, both by the operators themselves or by means of market or regulation enforcement motion,” FireEye Mandiant’s John Hultquist explained to CNBC.

It appears that REvil’s Satisfied Web site was taken offline all around 1 AM EST on Tuesday, with vx-underground noting that the group’s community-facing consultant, Unidentified, has not posted on popular hacking message boards this kind of as Exploit and XSS considering that July 8.

Subsequently, a consultant for LockBit ransomware posted to the XSS Russian-talking hacking discussion board that REvil’s assault infrastructure acquired a government authorized ask for, producing the servers to be dismantled. “REvil is banned from XSS,” vx-underground afterwards included.

It really is not unusual for ransomware groups to go below the floor following remarkably publicized incidents. Immediately after the DarkSide gang targeted Colonial Pipeline in Might, the operators declared options to wind up its RaaS affiliate method for superior, declaring that its servers had been seized by an not known regulation enforcement agency, elevating queries as to whether the group really retired, or rebranded underneath a new title.

This principle was ultimately validated when the U.S. Section of Justice discovered final month that it was able to recuperate most of the cash compensated by Colonial Pipeline to the DarkSide group through an examination of the bitcoin trails.

REvil’s unexplained shutdown, in a equivalent style, might as well be a case of planned retirement, or a short-term setback, forcing it to seemingly disband only to ultimately reassemble less than a new identity so as to draw in significantly less awareness, or may well have been the consequence of greater intercontinental scrutiny in the wake of the international ransomware crisis.

If it in fact turns out that the team has forever shuttered operations, the shift is sure to depart the group’s targets in the lurch, with no viable means to negotiate ransoms and get hold of the decryption keys required to regain regulate of their devices, as a result forever locking them out of their facts.

“I will not know what this means, but regardless, I am happy!” tweeted Katie Nickels, director of intelligence at Red Canary. “If it truly is a authorities takedown – magnificent, they’re taking motion. If the actors voluntarily went tranquil – outstanding, possibly they’re frightened.”
