This pest originated in Spain in April 2002. The author is a hacker
called Yav_69. 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.
