A compromised admin account is used to disable logging services.

The correct answer is A, Anti-forensics. Disabling logging services after compromising an administrator account is an attempt to hide evidence, prevent detection, and make later investigation harder. In CEH system hacking phases, this aligns with covering tracks, where an attacker removes or modifies evidence after gaining access. The CEH material describes covering tracks as wiping evidence, removing event logs, error messages, and other indicators so the attack is not easily discovered. It also lists disabling auditing, clearing logs, and manipulating logs as common techniques used by attackers. CEH hacking methodology also explains that clearing tracks helps attackers remain undetected by overwriting system, application, and related logs to avoid suspicion. This is not exfiltration, because no data theft is described. It is not reconnaissance, because the attacker is not gathering information. It is not privilege escalation, because the account is already administrative. Therefore, disabling logging services is best classified as anti-forensics or covering tracks.
