GWBoy

This RAT application was created by a group called Programming Group Of
Gdufs. 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 pest uses
"backdoor" abilities to gain the intruder a completely invisible access
to your PC. Several variants of this pest appeared from April
2003 to May 2003. The virus is compressed with ASPack. The origination
place is Taiwan.
