4 days in the past, the REvil ransomware gang’s leak website, generally known as the “Comfortable Weblog,” went offline. Cybersecurity specialists puzzled aloud what might need brought about the notorious group to go darkish as soon as extra.
One concept was that it was an inside job pulled by the group’s disaffected former chief. One other was that legislation enforcement had efficiently hacked and dismantled the group. “Usually, I’m fairly dismissive of ‘legislation enforcement’ conspiracy theories, however provided that legislation enforcement was in a position to pull the keys from the Kaseya assault, it’s a actual chance,” Allan Liska, a ransomware skilled, instructed ZDNet on the time.
“Rebranding occurs lots in ransomware after a shutdown,” he stated. “However nobody brings outdated infrastructure that was actually being focused by each legislation enforcement operation not named Russia on the planet again on-line. That’s simply dumb.”
Nicely, apparently, whoever relaunched REvil wasn’t the brightest bulb. Final night time, Reuters reported that a number of international locations working collectively took down the ransomware gang utilizing one of many felony group’s favourite techniques—compromised backups.
Although the FBI isn’t commenting on the matter, private-sector cybersecurity specialists and a former US official confirmed the operation, Reuters studies. “The FBI, along with Cyber Command, the Secret Service, and like-minded international locations, have actually engaged in important disruptive actions towards these teams,” Tom Kellermann, VMware’s head of cybersecurity technique and an adviser to the US Secret Service on cybercrime investigations, instructed Reuters. “REvil was high of the listing.”
“The gloves have come off”
The newfound success towards the slippery gang stems partially from the brand new authorized freedom to pursue such felony operations. US Deputy Legal professional Basic Lisa Monaco not too long ago decided that ransomware assaults on essential infrastructure are a nationwide safety risk on par with terrorism. That allowed the Justice Division to usher in help from the Pentagon and US intelligence companies.

“Earlier than, you couldn’t hack into these boards, and the army didn’t wish to have something to do with it,” Kellermann stated. “Since then, the gloves have come off.”
REvil was probably the most infamous ransomware gangs in recent times. The group first appeared in 2019, and over the past 12 months, it racked up a laundry listing of victims. The primary was a celeb legislation agency that represented Woman Gaga, U2, and Madonna. The agency refused to pay the $21 million ransom, so REvil revealed a few of Woman Gaga’s paperwork. Subsequent up was contract producer Quanta Laptop. REvil stole confidential knowledge from the corporate and revealed particulars of two Apple merchandise. In Could, the group hacked Colonial Pipeline’s operations, inflicting widespread gas shortages from New Jersey to Texas. In June, it attacked JBS, a meat processor, shutting down vegetation within the US, Canada, and Australia.
Lastly, in July, REvil hacked software program from Keseya, an IT agency. The corporate’s compromised distant administration instruments have been utilized by 54 providers suppliers to function many as 1,500 organizations. Victims of the assault ranged from grocery shops to hospitals, city halls, and companies.
Strategic delay
In September, a report by The Washington Publish revealed that the FBI had hacked REvil’s servers and obtained a common decryption key however didn’t inform victims for 3 weeks. On the time, FBI Director Christopher Wray testified earlier than Congress that the delay was strategic. “We make the selections as a bunch, not unilaterally,” he stated. “These are advanced… selections, designed to create most affect, and that takes time in going towards adversaries the place we’ve to marshal assets not simply across the nation however everywhere in the world.”
Withholding the important thing seems to have paid off. The FBI and its collaborators have been in a position to burrow deep sufficient into REvil’s operations that legislation enforcement’s software program remained hidden in backups that have been not too long ago utilized by gang member “0_neday” to revive operations. When he spun issues up once more, he unknowingly granted legislation enforcement entry to a number of the programs, Oleg Skulkin, deputy head of the forensics lab on the Russian-led safety firm Group-IB, instructed Reuters.
“Paradoxically, the gang’s personal favourite tactic of compromising the backups was turned towards them,” Skulkin stated.
