A Russian-based hacker group blamed for a massive ransomware attack earlier this month has gone offline, sparking speculation about whether the move was the result of a government-led action.
The webpages of the group known as REvil disappeared from the dark web on July 13, cybersecurity researchers said. Both its data-leak site and ransom-negotiating portals were unreachable.
The researchers said that it was unclear whether the outage was the result of actions taken by law enforcement or whether REvil had voluntarily taken down its sites. The situation is still unfolding, but evidence suggests REvil has suffered a planned, concurrent takedown of their infrastructure, either by the operators themselves or via industry or law enforcement action, John Hultquist of Mandiant Threat Intelligence said in a statement quoted by AFP.

Threat intelligence researchers are looking closely at REvil, the ransomware gang that infected up to 1,500 companies in a single swoop. A look at part of the group s online infrastructure shows clear lines to Russian and U.K. service providers that, in theory, could help law enforcement agencies but don t appear eager to help.
On July 2, affiliates of REvil exploited several vulnerabilities in remote management software called the Virtual System Administrator from Miami-based Kaseya.
