What it detects
This rule detects deletion of Volume Shadow Copies through vssadmin or wmic, an anti-recovery step performed by Phobos ransomware deployed by the 8Base group. Removing shadow copies prevents victims from restoring encrypted files without paying. This inhibit-recovery behavior almost always precedes or accompanies ransomware encryption.
