This is a RAT tool, used by hackers to gain remote control over
someone's computer. The attacker infects his victim via the e-mail or
the File and Print Sharing system with a "server" program. Once inside
the system, the virus opens a default TCP port 3000 or 23777 and awaits
commands from the intruder. He can connect using a "client" program on
his own PC. The functions of a RAT may vary, depending on the needs of
the intruder. This virus is compressed with ASPack. It affects Windows
95/98/ME operating systems. It was designed to steal cached passwords.
The pest originated in Russia in May 2000.
