Definition:
RATs, or Remote Access Trojans, provide a "backdoor" into the system through which the unscrupulous hacker can snoop into your system - even running other malicious code if s/he chooses. They can even use these hijacked systems, called zombies, to launch attacks on others. Some examples of RATs include Sysbug, Back Orifice, and Lamer's Death. For more information on RATs, see: Haunting Thought: Is Your PC a Zombie?.
Also Known As: RAT, backdoor
