BlogXX is a financially motivated ransomware group that emerged in April 2022, operating under a Ransomware-as-a-Service model. The group is widely believed to be a relaunch or direct variant of the defunct REvil ransomware operation, leveraging similar code and employing the alias Sodinokibi in private negotiations. Its primary motivation is financial gain through double extortion, which involves encrypting victim data while also stealing sensitive information for public release if a ransom is not paid. A distinguishing characteristic of BlogXX is its strong, almost synonymous, link to the previous REvil infrastructure and methodology, making it difficult to differentiate where one ends and the other begins, which suggests a continuation of operations under a new guise following law enforcement disruptions against REvil.
