Brief Description 

    
Mitglieder.HL is a worm with the characteristics of a Trojan.
Mitglieder.HL 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.HL 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.HL prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).

 

Mitglieder.HL 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.HL uses the following propagation or distribution methods:

  • Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
  • Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
  • Email: sending emails that include a copy of itself as an attachment. The computer is infected when the attachment is run.
