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 port 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 RAT was created in December 2001.
