What it detects

This rule detects the destruction of volume shadow copies and disabling of Windows recovery options, a hallmark of WannaCry and other ransomware families. The activity removes backups via vssadmin and wmic, disables boot recovery via bcdedit, or deletes the backup catalog via wbadmin to prevent victim recovery. This behavior almost always precedes or accompanies file encryption and warrants immediate response.
