Parent class: TrojWare

Trojans are malicious programs that perform actions which are not authorized by the user: they delete, block, modify or copy data, and they disrupt the performance of computers or computer networks. Unlike viruses and worms, the threats that fall into this category are unable to make copies of themselves or self-replicate. Trojans are classified according to the type of action they perform on an infected computer.

Class: Trojan-Spy

Trojan-Spy programs are used to spy on a user’s actions (to track data entered by keyboard, make screen shots, retrieve a list of running applications, etc.) The harvested information is then transmitted to the malicious user controlling the Trojan. Email, FTP, the web (including data in a request) and other methods can be used to transmit the data.

Platform: Win32

Win32 is an API on Windows NT-based operating systems (Windows XP, Windows 7, etc.) that supports execution of 32-bit applications. One of the most widespread programming platforms in the world.


Technical Details

This Trojan logs the user’s keystrokes. This Trojan is designed to steal a range of confidential information. It harvests information entered via the keyboard and the mouse. It is a Windows PE EXE file. It is 4,096 bytes in size. It is packed using UPX. The unpacked file is approximately 15KB in size.


In order to ensure that the Trojan is launched automatically each time Windows is restarted, the Trojan registers its executable file in the system registry:



The Trojan installs a hook which intercepts keyboard events. This enables the Trojan to track information entered via the keyboard in active windows. The Trojan saves harvested data to a log file. This file is located in the same folder as the Trojan. It will have the same name as the Trojan executable file, and a .DLL extension.

The log file contains the titles of the windows used, together with the sequence of symbols entered via the keyboard.

The log file will be periodically uploaded to an FTP server.

Removal instructions

If your computer does not have an up-to-date antivirus, or does not have an antivirus solution at all, follow the instructions below to delete the malicious program:

  1. Use Task Manager to terminate the Trojan process.
  2. Delete the original Trojan file (the location will depend on how the program originally penetrated the victim machine).
