REvil, the notorious ransomware cartel powering some of the major cyberattacks focusing on JBS and Kaseya, has mysteriously disappeared from the dark web, primary to speculations that the prison organization could have been taken down.
A number of darknet and clearnet websites managed by the Russia-connected cybercrime syndicate, which include the information leak, extortion, and payment portals, remained inaccessible, displaying an mistake information “Onionsite not discovered.”
The group’s Tor network infrastructure on the dark web is made up of one info leak web site internet site and 22 info hosting sites. It can be not instantly very clear what prompted the infrastructure to be knocked offline.
REvil is just one of the most prolific ransomware-as-a-service (RaaS) groups that initially appeared on the risk landscape in April 2019. It is really an evolution of the GandCrab ransomware, which strike the underground marketplaces in early 2018.
“If REvil has been permanently disrupted, it’ll mark the finish of a group which has been accountable for >360 assaults on the U.S. general public and personal sectors this 12 months alone,” Emsisoft’s Brett Callow tweeted.
The unexpected growth comes near on the heels of a wide-scale source chain ransomware attack aimed at technology solutions supplier Kaseya, for which REvil (aka Sodinokibi) took accountability for and demanded a $70 million ransom to unlock obtain to encrypted devices in exchange for a universal decryption vital that would unlock all victims details.
The disastrous attack noticed the ransomware gang encrypting roughly 60 managed provider vendors (MSPs) and in excess of 1,500 downstream businesses applying a zero-working day vulnerability in the Kaseya VSA remote management software package. In late Could, REvil also masterminded the attack on the world’s most significant meat producer JBS, which ended up having to pay $11 million to the extortionists to recuperate from the incident.
The outage also coincides with U.S. President Joe Biden’s phone contact with Russian President Vladimir Putin past week, urgent the latter to take actions to disrupt ransomware groups running in the country, even though warning of retaliatory action to defend critical infrastructure.
“The problem is however unfolding, but evidence indicates REvil has experienced a prepared, concurrent takedown of their infrastructure, possibly by the operators on their own or by using business or regulation enforcement motion,” FireEye Mandiant’s John Hultquist explained to CNBC.
It seems that REvil’s Satisfied Web site was taken offline all over 1 AM EST on Tuesday, with vx-underground noting that the group’s community-struggling with agent, Unknown, has not posted on preferred hacking discussion boards these types of as Exploit and XSS due to the fact July 8.
Subsequently, a agent for LockBit ransomware posted to the XSS Russian-talking hacking forum that REvil’s attack infrastructure been given a govt authorized request, causing the servers to be dismantled. “REvil is banned from XSS,” vx-underground later extra.
It is not unusual for ransomware groups to go below the floor next extremely publicized incidents. Soon after the DarkSide gang focused Colonial Pipeline in May possibly, the operators introduced plans to wind up its RaaS affiliate method for superior, claiming that its servers had been seized by an unfamiliar regulation enforcement company, boosting thoughts as to no matter if the team really retired, or rebranded below a new identify.
This idea was finally validated when the U.S. Office of Justice disclosed last thirty day period that it was ready to get better most of the income paid by Colonial Pipeline to the DarkSide group through an assessment of the bitcoin trails.
REvil’s unexplained shutdown, in a equivalent style, may as nicely be a situation of prepared retirement, or a short-term setback, forcing it to seemingly disband only to finally reassemble under a new identification so as to catch the attention of significantly less notice, or might have been the consequence of enhanced worldwide scrutiny in the wake of the global ransomware disaster.
If it indeed turns out that the group has permanently shuttered operations, the go is sure to go away the group’s targets in the lurch, with no viable implies to negotiate ransoms and get maintain of the decryption keys essential to get back management of their devices, so permanently locking them out of their data.
“I do not know what this usually means, but no matter, I am content!” tweeted Katie Nickels, director of intelligence at Red Canary. “If it really is a government takedown – awesome, they are getting action. If the actors voluntarily went quiet – fantastic, probably they are terrified.”
