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 in computing uses the same image: imagine an actor on stage who is really a hidden program or robot that breaks the rules or steals things, so people call a harmful program or agent in a system a 'bad actor'.
