Brief Description 

    

Protoride.DH is a worm that spreads by copying itself, without infecting other files.

 

It reduces the security level of the computer: it awaits remote-control orders received through IRC.

 

Protoride.DH 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 injects itself in running processes.
  • It modifies system permissions in order to hide itself.

 

It uses several methods in order to avoid detection by antivirus companies:

  • It prevents scanning tools from running, such as Windows Registry Editor, FileMonitor, etc.

 

Protoride.DH 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.
  • IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
  • Computer networks (mapped drives): it creates copies of itself in mapped drives.
  • Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
