Technical Details


The executable file containing the installer for the Poweliks trojan is typically distributed through spam email campaigns or by exploit kits . When delivered via an exploit kit, F-Secure products may identify the exploit attempting to gain access to a targeted device with the detection name, "Exploit.Poweliks.Gen".

When the installer is launched on the device, the trojan's malicious code is not saved in a file (as is typical of most other malware), but in a registry key in the Windows Registry. This behavior makes it much harder for the user to recognize the presence of a malicious program on their system.

Once the code is installed, the Poweliks installer deletes itself to leave even less evidence on the device.

Based on the specific variant of the Poweliks trojan installed, the malware may:

  • Harvest system information and forward it to a remote server
  • Perform clickfraud (also known as clickjacking)
  • Download additional malware onto the device
  • Contact a remote server to obtain additional instructions from the attacker
