What it detects

This rule detects cipher.exe run with the /w wipe switch, which overwrites free disk space and is abused to destroy recoverable data or securely erase attacker artifacts. Data destruction via cipher is an impact and anti-forensic technique tracked in the Red Canary Threat Detection Report. Detecting this invocation surfaces deliberate data wiping.
