Sodinokibi/REvil, Avaddon and DarkSide ransomware groups shut down from May to July, but the affiliates that conducted attacks on behalf of these groups have shifted to new groups such as LockBit and emerging ransomware groups.
That is where X-Force IR can help.īecause many ransomware affiliates interact, cross-pollinate and operate on behalf of different ransomware groups, we don’t attribute the following activities to any particular ransomware group they are common across multiple ransomware groups. By leveraging the default WELs, many ransomware victims have the data they need to detect ransomware operators they simply need to know where to look. This blog will review several opportunities security teams have to detect most ransomware adversaries within the default WELs. In particular, the X-Force IR team has identified several actions ransomware operators take that are common across almost all ransomware attacks - and are also relatively easy to detect through search queries and detection mechanisms identified by X-Force IR.

Leveraging that access and knowledge against the ransomware threat has revealed tools, techniques and procedures that can often be detected through the default Windows event logs (WELs). One of the benefits of being part of a global research-driven incident response firm like X-Force Incidence Response (IR) is that the team has the ability to take a step back and analyze incidents, identifying trends and commonalities that span geographies, industries and affiliations.
