😈 How to Detect Linux Anti-Forensics Log Tampering

When forensically examining Linux systems for malicious intrusion, responders often rely on the following three artefacts to determine logins and logouts:

— /var/run/utmp – currently logged in users
— /var/run/wtmp – current, past logins and system reboot
— /var/log/btmp – bad login attempts

Of course, these artefacts are not all you can forensically investigate for malicious access, however, these will be the focus of this anti-forensics blog post.
