Threat: Backdoor.Win32.Kraimer.11
Vulnerability: Missing Authentication 
Description: Kraimer listens for commands on TCP port 6668, due to a lack of authentication anyone can telnet to the infected host. Seems only one established connection at a time is allowed, so if you telnet in then no other connections are honored. Therefore, if you make TCP connection and  theres already an established connection you will get refused.

Successful backdoor logon:

 1) Help          
 2) View Log File            
 3) Start Key Logging                        
 4) Stop Key Logging

 6) View Saved Passwords                                         
 7) Reboot
