Trojans and Backdoors

Trojans and Backdoors are sorts of Bad-wares which their main purpose is to send and receive data and especially commands through a port to another system. This port can be even a well-known port such as 80 or an out of regular ports like 7777. The Trojans are most of the time defaced and shown as a legitimate and harmless application to encourage the user to execute them. The main characteristic of a Trojan is that first it should be executed by the user, second sends or receive data with another system which is the attacker’s system.
