What it detects

This rule detects deletion of all volume shadow copies through vssadmin, an inhibit-recovery action the RA World ransomware group performs to prevent victims from restoring encrypted files. Destroying shadow copies is a hallmark of ransomware staging. Detecting this exposes imminent or in-progress encryption impact on the host.
