More Information

Troj/Feutel-AB is a backdoor Trojan for the Windows platform.

Troj/Feutel-AB attempts download code and allow unauthorised access to an attacker.

When first run Troj/Feutel-AB copies itself to <Windows>\sServer.exe and creates the following files:

<Windows>\sServer.DLL
<Windows>\uninstal.bat

The file sServer.exe is registered as a new system driver service with a name composed of non-roman characters and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:

HKLM\SYSTEM\CurrentControlSet\Services\<non-roman characters>\
