A Remote Administration Tool is a special kind of hacker malware, used for remote access and control of other people's PCs. The attacker infects the PC via the e-mail or File and Print Sharing. A "server" allows him to connect via a "client" on his own machine. The functions of a RAT may vary, depending on the needs of the hacker. Some RATs can't really harm your PC and the only purpose they were made for is hooliganism. But some versions can steal vital information, remove files and even crash your computer. This RAT uses "backdoor" abilities to infiltrate the computer and allow the intruder to stay unnoticed for a long period of time. Several versions of this hacking tool appeared in the internet from April 2001 to July 2003. The author is a Chinese hacker called NetBull.
