CriticalCompromise indicatorsBLWK-FIM-005

Credential file deleted since baseline: ‹path›

What this means

‹path› was present at the last baseline and is now missing. A missing /etc/shadow or /etc/sudoers is either severe accidental damage or deliberate tampering — neither leaves this host in a safe state.

How to fix it

Restore the file immediately from a package manager reinstall or backup — do not leave this host running without it. Then re-run sudo bulwark fim baseline --privileged.

Check it yourself

Run a scan and look for BLWK-FIM-005 in the results:

bulwark scan

Installed the standalone CLI package instead of the app? The command is bulwarkctl.

How Bulwark decides

Bulwark reads file_integrity_privileged and reports this check when:

changed == true and currently_present == false

If a value can't be read, Bulwark reports the check as undetermined rather than passing it. View the rule source.
