Threat: Backdoor.Win32.Zxman
Vulnerability: Missing Authentication 
Description: Backdoor.Win32.Zxman by Zx-man listens on TCP port 2048 for commands. However, anyone who can reach the infected host can take control as there is no authentication in place. Not much of a self-respecting backdoor. Third party intruders or incident responders who logon will be greeted with a welcome screen and help menu allowing for a wide-range of commands.
