"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.

"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
