More Information

Troj/Domwis-E is an IRC backdoor Trojan that allows a remote user access to an infected computer.

When first run, the Trojan copies itself to the Windows folder as a hidden file named PASSCFG16.EXE.

In order to run automatically each time a user logs in, the Troj/Domwis-E sets the following registry entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Windows System Configuration
<Windows>\PASSCFG16.EXE

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Windows DLL Loader
<Windows>\PASSCFG16.EXE

Troj/Domwis-E can be used to:

delete, download, upload and execute remote files.
perform denial-of-service (DoS) attacks.
steal system information.
log key presses.
create screen and webcam captures.
scan other computers for open ports and vulnerabilities.

Troj/Domwis-E may create the file TEMP.BAT in the Windows folder. The file is used to add a user to the Administrators local group. This file can be safely deleted.
