Brief Description 

    

Koobface.FF is a worm that spreads by copying itself, without infecting other files.

 

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

  • It uses techniques included in its code to hide itself while it is active.
  • It deletes the original file from which it was run once it is installed on the computer.

 

Koobface.FF 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.
  • Instant messaging: it sends links pointing to a copy of itself to all users included in the infected user's contacts list.
