Research update for HackTricks content

🤖 Agent Actions

I’m reading the target page and nearby forensics content first so I can see what is already covered before adding anything. After that I’ll do web research against recent Linux forensic tradecraft and tooling, then patch only the gaps that add real value.
The page already covers classic live response and persistence hunts, so I’m checking the rest of it plus adjacent HackTricks pages to avoid re-adding things that already live in file-integrity, memory, or anti-forensics sections. Next I’m looking for specific gaps that can be filled with recent Linux-focused forensic techniques rather than generic DFIR content.
I have the local scope now. I’m moving to external research to confirm which Linux forensic additions are both recent and specific enough to improve this page: journald/audit artifacts, systemd persistence traces, and file metadata that attackers abuse but investigators often miss.
I’ve narrowed the likely additions to three concrete areas that the page is thin on: journalctl offline/verification workflows, auditd queries that matter during incident response, and metadata-based triage for capabilities, xattrs, and ld.so.preload style userland rootkits. I’m pulling source material now and then I’ll splice in only the commands that materially improve this page.
I have enough to patch safely. The edit is going to add three compact forensic upgrades: offline journalctl/auditd triage, systemd timer and transient-unit hunting, and filesystem metadata checks for capabilities, xattrs, and /etc/ld.so.preload abuse.
The content is patched. I’m doing a final read-through of the diff now to catch any markdown or accuracy issues before I close out.
Updated linux-forensics.md.

I added four practical upgrades that fit the existing page: journalctl offline and integrity-focused triage, auditd/ausearch/aureport incident-response pivots, hunting for systemd timers and transient units under /run/systemd/transient, and filesystem metadata checks for getcap, getfattr, and /etc/ld.so.preload abuse. I also appended two relevant references at the end without changing the page structure.
