Type:
Trojan Horse

Backdoor.Rat.Client is a client program which allows access to Backdoor.Rat.

When Backdoor.Rat is installed on a Microsoft Windows system, this backdoor Trojan horse program lets others gain full access to the system through a network connection. Backdoor.Rat is divided into 2 parts: a client and a server. Both applications are capable of running under Windows 95, 98, and NT 4.0. The client application running on one computer might be used to monitor and control a second computer 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 cannot infiltrate the server. It does not matter whether the TCP or UDP protocol is implemented. There have not been any reports of this program breaking through a firewall.
