DonaldD.Trojan

Risk Level 2: Low

Discovered:

Type:
Trojan Horse

The DonaldD.Trojan is similar to the BackOrifice.Trojan. When installed in Microsoft Windows, this backdoor Trojan horse program enables others to gain full access to the system through a network connection. It consists of two parts: a server application and a client application. Both applications can run under Windows 95, 98, and NT 4.0. The client application, running on one computer, may 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 will not be able to infiltrate the server. It does not matter whether the TCP or SPX protocol is implemented. There have not been any reports of this program being able to break through a firewall.
