Morphology

Trojan + Horse

The meaning is a metaphorical extension from the Greek myth (a deceptive wooden horse used to smuggle invaders in), so the core idea of deception/hidden threat is derivable once the cultural story is known. However, a B1 learner who only knows the literal senses 'Trojan' (person from Troy) and 'horse' is unlikely to infer the specific modern computing sense (malicious software disguised as legitimate code) without encyclopedic/cultural knowledge, so it is partially but not fully transparent.

Etymology

Trojan Horse for software is named after that wooden horse: just as the 'gift' hid soldiers, a program that looks useful but hides a 'harmful program' is called a Trojan Horse because it lets attackers secretly enter a computer. So, the term means 'a hidden bad program'.
