Brief Description 

    
Mitglieder.CH is a worm with the characteristics of a Trojan.
Mitglieder.CH spreads by copying itself, without infecting other files. Its main objective is to collapse computers and networks, preventing users from working with their computers.
Furthermore, due to its Trojan characteristics, Mitglieder.CH allows hackers to get into and carry out dangerous actions in affected computers, such as capturing screenshots, stealing personal data, etc.

 

It reduces the security level of the computer: it terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware.

 

Mitglieder.CH prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).

 

Mitglieder.CH accesses several websites to download files, which it then runs. These can be any type of file, although they are normally malware.

 

It uses stealth techniques to avoid being detected by the user:

  • It terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.

 

Mitglieder.CH 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.
