Brief Description 

    

Mitglieder.EK is a Trojan that attacks several security tools, such as antivirus programs and firewalls belonging to different companies, if they are installed on the affected computer:

  • It deletes key files for their correct functioning.
  • It deletes entries of the Windows Registry that allow them to be automatically run.
  • It stops services associated to those programs.
  • It ends processes belonging to applications that provide updates for antivirus programs.

Mitglieder.EK attempts to download a file called OSA4.GIF from different web addresses, and then runs it.

Mitglieder.EK does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.

Visible Symptoms 

    

Mitglieder.EK is easy to recognize once it has affected the computer, as it opens the Notepad program when it is run, but without displaying any text.
