Threat: Backdoor.Win32.Augudor.b  
Vulnerability: Remote File Write Code Execution   
Description: The malware drops an empty file named "zy.exe" and listens on TCP port 810. Third-party adversaries who can reach the infected host can write executable code to the empty "zy.exe" file on the system via a socket program and it will execute as soon as the binary transfer has completed. Successfully tested with a 880 byte executable.
