Brief Description 

    

MSNphoto.V is a worm that spreads by copying itself, without infecting other files.

 

It captures certain information entered or saved by the user, with the corresponding threat to privacy: passwords saved by certain Windows services.

 

It affects productivity, preventing tasks from being carried out:

  • In the affected computer: causes system slowdowns.
  • In the local network: it generates a large amount of network activity and consumes bandwidth.
  • On remote sites: it mass mails junk mail (spam).

 

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

  • It deletes the original file from which it was run once it is installed on the computer.

 

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

  • Its code is encrypted and it is only decrypted when it is going to run. Because of this, its code is not legible through a memory dump.

 

MSNphoto.V 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.
