Trojan Horse
From Conservapedia
The Trojan Horse was a mythological device used during the Trojan War. It was a large wooden horse on wheels, which was delivered to the gates of Troy as a supposed tribute by the Greeks. Secretly however, the Horse was made hollow, and filled with Greek soldiers, who came out at night and opened the city gates to let in the Greek army and attack the city.
In modern computing, the term has come to refer to a computer program which appears to have one function, but in reality has a completely different one that's harmful.[1]
