QQ Cat

This is a Remote Administration Tool that is used by hackers to control the victim's machine remotely. The possibilities of such application depend on the needs of the attacker. 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. Several versions of this pest originated in November 2000. The applicationming language is Visual Basic. The RAT was created by a Chinese hacker called BigCat.
