Linux Viruses and Such

• Non-malware:

• Rootkit: Post-compromise toolkit to hide an attacker's presence after he enters via other means entirely.

• [D]DoS tool: [Distributed] Denial of Service against remote host.

• Backdoor: Post-compromise covert means of re-entry for an attacker.

• Documented but misunderstood: E.g., “sendmail -C”.
