In fact, researchers at ReliaQuest found evidence that an initial SocGholish malware distribution was intended to deploy ransomware.

Profiling a Massive Portfolio of Domains Involved in Ransomware Campaigns

Security researcher Dancho Danchev discovered a portfolio of domains and IP addresses used by known threat actors in ransomware campaigns. The said portfolio consists of 62,763 domain names and 810 IP addresses. We analyzed a sample of these malicious properties using TIP and found that:

The Fight Against Hive Ransomware May Not Be Done as Yet-Unidentified Artifacts Show
