Backdoors

Backdoor programs are typically more dangerous than computer viruses, as they can be used by an intruder to take control of a PC and potentially gain access to an entire network.Backdoor programs, also referred to as Trojan horses, are typically sent as attachments to e-mails with innocent-looking file names, tricking users into installing them. They often enable remote users to listen in on conversations using the host computer's microphone, or even see through its video camera if it has one. Back Orifice (BO) （闯后门程序）2000 is a backdoor program designed for malicious use. Its main purpose is to maintain unauthorized control over another machine for reconfiguration and data collection. It takes the form of a client/server application that can remotely control a machine without the user's knowledge to gather information, perform system commands, reconfigure machines and redirect network traffic.
With BO an intruder has to know the user's IP address to connect, or could scan an entire network look for the victim. Once connected, the intruder can send requests to the BO 2000 server program, which performs the actions the intruder specifies on the victim's computer, sending back the results.
BO is installed on the server machine simply through the execution of the server application.
