More Information
Troj/Ranck-L is a backdoor Trojan that allows a remote intruder to route HTTP traffic through the computer.
Troj/Ranck-L sets the following registry entry to run itself on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\svchosts32
Troj/Ranck-L runs continuously in the background, listening on a randomly chosen TCP port in the range 10000-50000. The Trojan notifies a remote web server of the listening port via a web request.
