Overview
This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.

Characteristics
This remote access trojan simply acts as a server to provide a remote shell.
When run, this trojan listens on TCP port 8080 and runs the 'cmd.exe'. This trojan accepts only one TCP connection and once it is terminated, this trojan will be also terminated.
Symptoms
The indications of the presence of this trojan are typical for infection by remote access trojan:
- port 8080 open on machine.
- Unusual behaviour on victim machine, explainable by unauthorised remote administration.
Method of Infection
Trojans do not self-replicate. They are spread manually, often under the premise that the executable is something beneficial. Distribution channels include IRC, peer-to-peer networks, newsgroup postings, etc.
