Why is it called Trojan virus?

Trojan horse (hereinafter referred to as Trojan horse) is called "Trojan horse" in English, and its name is taken from the Trojan horse in Greek mythology.

According to ancient Greek legend, Paris, the prince of Troy, visited Greece and lured Queen Helen away, so the Greeks went to Troy. Nine years after the siege, in 10, the Greek general Odysseus put forward a plan to ambush a group of warriors in the belly of a huge wooden horse, put them outside the city and pretend to retreat. The Trojans thought that the enemy soldiers had retreated, so they moved the Trojan horse into the city as a trophy. At night, the warriors who were ambushed in the wooden horse jumped out to open the gate, and Greek soldiers swarmed in and captured the city. Later, people often used the allusion "Trojan horse" in writing articles to describe the activities of burying an ambush in the enemy camp.

In the computer field, it is a hacker tool based on remote control, which has the characteristics of concealment and unauthorized.

The so-called concealment means that the designers of Troy will use various means to hide Troy in order to prevent it from being discovered, so that even if the server finds that it is infected with Troy, it can only look at the horse and sigh, because it is impossible to determine its specific location.

The so-called unauthorized means that once the control terminal is connected to the server, the control terminal will enjoy most of the operating rights of the server, including modifying files, modifying the registry, controlling the mouse and keyboard, etc. And these rights are not given by the server, but stolen by the Trojan horse program.
