Ryuk’s Return

From The DFIR Report:

The Ryuk group went from an email to domain wide ransomware in 29 hours and asked for over $6 million to unlock our systems. They used tools such as Cobalt Strike, AdFind, WMI, vsftpd, PowerShell, PowerView, and Rubeus to accomplish their objective.

Ryuk has been one of the most proficient ransomware gangs in the past few years, with the FBI claiming $61 million USD having been paid to the group as of February 2020. Earlier in the year, the group grew a little quiet, but that seems to have changed in the past few weeks, with incidents like what occurred at UHS hospitals.
