What the reviewer found
A DFIR/forensics playbook for investigating an already-compromised Linux host from a mounted, read-only forensic image (/mnt/evidence) into the investigator's own case folder. Copying /etc/shadow, .ssh, and history files is the intended forensic-collection purpose, not live exfiltration; the 'rm -rf /' and 'chmod 777' strings are just entries in a list of suspicious command substrings the script greps for, never executed. Dual-use security tooling that requires root/evidence access to run.

How this review was made
Sonnet 5 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
