Back Orifice 2000 is a new version of BackOrifice.Trojan. When installed on a Microsoft Windows system, this backdoor trojan horse program allows others to gain full access to the system through a network connection. Similar to the original BackOrifice
, it consists of two pieces: a server and a client application. However, now both applications are capable of running under Windows NT. The client application, running on one machine, may be used to monitor and control a second machine running the server application.
The port number through which the client controls the server is configurable. However, as long as the port is blocked by a firewall, this trojan horse will not be able to infiltrate the server. It does not matter whether the TCP or UDP protocol is implemented. There have not been any reports of this program being able to break through a firewall.
