Short description

The trojan serves as a backdoor. It can be controlled remotely.


When executed, the trojan copies itself into the following location:

  • %localappdata%\­%variable1%%variable2%\­%malwarefilename%

In order to be executed on every system start, the trojan sets the following Registry entry:

  • [HKEY_CURRENT_USER\­SOFTWARE\­Microsoft\­Windows\­CurrentVersion\­Run]
    • "%variable1%%variable2%" = "%localappdata%\­%variable1%%variable2%\­%malwarefilename%"

The trojan may set the following Registry entries:

  • [HKEY_CURRENT_USER\­SOFTWARE\­Microsoft\­Windows\­CurrentVersion\­Run]
    • "{%variable3%}" = "%malwarefilepath%"

This causes the trojan to be executed on every system start.

A string with variable content is used instead of %variable1%, %variable3% .

The %variable2% is one of the following strings:

  • works
  • tion
  • soft
  • ics
  • media
  • Pack

The trojan terminates its execution if it detects that it's running in a specific virtual environment.
