What it detects

This rule detects vssadmin deleting all volume shadow copies quietly which Eldorado ransomware runs to inhibit system restore before encryption. Removing shadow copies prevents victims from recovering files without paying the ransom. It is important because shadow copy deletion is a reliable pre-encryption impact indicator.
