CompTIA Linux+ XK0-006 (V8) Practice Question

During a forensic review of a compromised CentOS web server, the incident-response team extracts several artifacts that could be shared as threat-intelligence. Which item is the most appropriate high-fidelity host-based indicator of compromise that other organizations can safely use to detect the same malware on their own Linux systems?

  • The server's public IPv4 address during the attack

  • The SHA-256 hash of the malicious ELF binary found in /usr/local/bin

  • The timestamp of the first failed SSH login in /var/log/secure

  • The process ID the malware used while it was running
