Settra Ransomware Anti-Forensic Disk Wipe via cipher.exe /w:
Detects the use of the built-in Windows 'cipher.exe' utility with the '/w' flag, which is used to securely overwrite free space on a disk, a technique often used by adversaries for anti-forensics or data destruction to prevent file recovery. The rule specifically alerts on execution from command-line environments (cmd.exe) where the command output is redirected to null, often used to hide the progress or output of the wiping process.
