The Trojan Horse
The term comes from Greek mythology, in which the Greeks battled the Trojans (people of Troy) in the 12th century BC. After years of being unable to break into the fortified city, the Greeks built a wooden horse, filled it with soldiers and pretended to sail away. After the Trojans brought the horse into the city, the Greek soldiers crept out at night, opened the gates of Troy to the returning soldiers, and Troy was destroyed.
