The trojan exists only to download and execute a remote file (path to which is stored in the trojan). Access to the following domains should be blocked at the firewall to prevent the file download:

http://marnet.us
http://animalloversleague.org
http://technalytics.net
When run, it attempts to download this file via HTTP, saving it to the Windows system directory as TEMPFILE.EXE or TMPFILE.EXE

%SysDir%\TEMPFILE.EXE
%SysDir%\TMPFILE.EXE
This file is then executed.

Obviously the exact contents of this file may change. At the time of writing it is a remote access trojan, detection for which is included in Daily Dats as BackDoor-BAC .
