The notorious ransomware operation known as REvil (aka Sodin or Sodinokibi) has resumed after six months of inactivity, an analysis of new ransomware samples has revealed. "Analysis of these samples indicates that the developer has access to REvil's source code, reinforcing the likelihood that the threat group has reemerged," researchers from Secureworks Counter Threat Unit (CTU)  said  in a report published Monday. "The identification of multiple samples with varying modifications in such a short period of time and the lack of an official new version indicates that REvil is under heavy active development once again." REvil, short for Ransomware Evil, is a ransomware-as-a-service (RaaS) scheme and attributed to a Russia-based/speaking group known as  Gold Southfield , arising just as  GandCrab  activity declined and the latter announced their retirement.

"Unfortunately, the Happy Blog is back online," Emsisoft threat researcher Brett Callow  tweeted  on Tuesday. The development comes a little over two months after a  wide-scale supply chain ransomware attack  aimed at Kaseya, which saw the Russia-based cybercrime gang encrypting approximately 60 managed service providers (MSPs) and over 1,500 downstream businesses using a zero-day vulnerability in the Kaseya VSA remote manage
