Explanation

In cybersecurity, an 'idle' system is referred to as a 'zombie.' This term is used in two contexts: (1) a zombie is a compromised machine that has been secretly enslaved into a botnet to carry out attacks on behalf of an attacker, and (2) in the context of idle scanning (a stealthy port scanning technique), an idle/zombie host is one with predictable IP ID sequences that an attacker exploits to perform anonymous scans. A 'bot' (D) is closely related but refers to the malicious software running on the zombie, not the host itself.
