Analyzing Linux System Artifacts

When to Use

• When investigating a compromised Linux server or workstation
• For identifying persistence mechanisms (cron, systemd, SSH keys)
• When tracing user activity through shell history and authentication logs
• During incident response to determine the scope of a Linux-based breach
• For detecting rootkits, backdoors, and unauthorized modifications

Prerequisites

• Forensic image or live access to the Linux system (read-only)
• Understanding of Linux file system hierarchy (FHS)
• Knowledge of common Linux logging locations (/var/log/)
• Tools: chkrootkit, rkhunter, AIDE, auditd logs
• Familiarity with systemd, cron, and PAM configurations
• Root access for complete artifact collection
