write a short note on trojan horse
in computing, a Trojan horse is a proram that appears harmless, but is, in fact, malicious. The term comes from Greek mythology about the Trojan War. According to legend, the Greeks built a large wooden horse that the people of Troy pulled into the city. During the night, soldiers who had been hiding inside the horse emerged, opened the city's gates to let their fellow soldiers in and then overran the city.
Attackers have long used Trojan horses as a way to trick end users into installing malware. Typically, the malicious programming is hidden within an innocent-looking email attachment or free program, such as a game. When the user downloads the Trojan horse, the malware that is hidden inside is also downloaded. Once inside the computing device, themalicouse codecan execute whatever task the attacker designed it to carry out.
