Short description

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

Installation

When executed, the trojan copies itself in some of the the following locations:

  • %windir%\­%variable1%.exe
  • %programfiles%\­%variable1%.exe
  • %windir%\­%variable2%\­%variable1%.exe
  • %programfiles%\­%variable2%\­%variable1%.exe

The trojan registers itself as a system service using the following name:

  • %variable3%

A string with variable content is used instead of %variable1-3% .


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


The trojan launches the following processes:

  • %systemdrive%\­Program Files\­Internet Explorer\­IEXPLORE.EXE

The trojan creates and runs a new thread with its own code within these running processes.


After the installation is complete, the trojan deletes the original executable file.
