Morphology

bad + actor

The meaning is partially derivable: 'bad' (harmful) + 'actor' (one who acts) would lead a B1 learner to infer 'someone/something that does harm' or 'someone who behaves badly.' However, the specific cybersecurity sense (a malicious non-human agent, e.g. malware or a bot) is a technical extension and the non-human/technical nuance is not fully predictable from the constituents alone, making it only partially transparent.

Etymology

Bad actor comes from the picture of a stage where a bad actor acts poorly or breaks the rules and ruins the show, so the phrase now means 'a person who causes trouble, behaves badly, or fails at their role'.
