More Information

Troj/Stinx-B is a backdoor Trojan for the Windows platform.

Troj/Stinx-B runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.

Troj/Stinx-B may arrive as an attachment to an email with the subject line 'Photo Approval Needed'. The filename used is 'Photo + Article.exe'.

When first run Troj/Stinx-B copies itself to <System>\csmsv.exe.

The following registry entries are created to run csmsv.exe on startup:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
ManageProtoclCtrl
csmsv.exe

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
ManageProtoclCtrl
csmsv.exe

Troj/Stinx-B can be instructed to delete, execute, and download and execute files.

Troj/Stinx-B will also try and circumvent the Windows Firewall if it is present.
