More Information

Troj/Agent-HPC is a backdoor Trojan which allows a remote intruder to gain access and control over the computer.

Troj/Agent-HPC includes functionality to access the internet and communicate with a remote server via HTTP.

When first run Troj/Agent-HPC copies itself to randomly generated filenames in the Windows system folder.

A registry entry such of the following form is created to run the Trojan on startup:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
<randomly generated string>
<path to copy of Trojan>

The Trojan is registered as a new system driver service with randomly chosen name and display name. The service will start automatically during system startup. Registry entries are created under:

HKLM\SYSTEM\CurrentControlSet\Services\<randomly generated string>
