Category Description:
Trojans are malicious applications that pose themselves as legitimate software in order to trick users to install them. Once on the victim's machine, it may run any number of malicious process to steal vital information or inflict damage to other software.
Comment:
Upon execution of this program the trojan copies itself into the Windows system directory and registers itself in the system registry so that it will start each time an infected system is rebooted. Once this is done it sends a notice via e-mail or ICQ (according to settings made by its author), and then begins to listen to a given TCP/IP port clandestinely. Having received the message sent back by the virus (information about specific networks sent back by the virus via ICQ or e-mail), the hacker controlling Backdoor.CyberSpy, with the help of any telnet-client, gains access to a victim computer's command line (prompt).
