Summary Points Ransomware operators are making costly mistakes, such as hardcoding recovery keys or discarding private keys, which hinder victim recovery efforts and reduce their leverage. Despite the general illegality of cybercrime in CIS countries, local authorities often provide safe harbor, allowing cybercriminal groups to operate with minimal interference, especially if they avoid in-country targets. Certain ransomware groups explicitly prohibit targeting CIS organizations, highlighting strategic operational boundaries and potential consequences of attacking in-region entities. Threat, Attack Techniques, and Targets The threat involves a ransomware affiliate program called Nova, linked to the larger RAlord crew. This group conducts ransomware attacks mainly…
