What it detects

This rule detects the deletion of volume shadow copies, backup catalogs, and recovery configuration through native Windows utilities, a recovery-inhibition step performed by Hunters International affiliates before encryption. Destroying backups to prevent restoration is a hallmark of ransomware impact activity and should be treated as high priority.
