More Information

Troj/Progent-A is a backdoor Trojan for the Windows platform.

When first run, the Trojan displays the following message box:

Error
No Theme Editor 6600 In Your Computer

Troj/Progent-A includes functionality to:

- access the internet and communicate with a remote server via HTTP
- steal information and passwords from a number of games and applications
- send notification messages to remote locations
- log key presses

Troj/Progent-A will attempt to disable a number of anti-virus and security-related applications. The Trojan will attempt to hide its activity from the user.

When first run Troj/Progent-A copies itself to <Windows>\qservice.exe and creates the following files:

<Windows>\JiurlPortHide.sys
<Windows>\k_urlmon.dll - text file containing keylogs
<Windows>\kurlmon.dll
<Windows>\services.dll
<System>\HookApi.dll
<System>\drivers\KeenSense.sys - text file
<System>\drivers\ksdevice.sys - text file

The following registry entry is created to run qservice.exe on startup:

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
qservices
<Windows>\qservice.exe

The file JiurlPortHide.sys is registered as a new system driver service named "JiurlPortHide", with a display name of "JiurlPortHide". Registry entries are created under:

HKLM\SYSTEM\CurrentControlSet\Services\JiurlPortHide\

Troj/Progent-A sets the following registry entry, disabling the automatic startup of other software:

HKLM\SYSTEM\CurrentControlSet\Services\srservice
