Brief Description 

    

Sdbot.MAO is a worm that spreads by copying itself, without infecting other files.

 

It affects productivity, preventing tasks from being carried out:

  • In the affected computer: it converts the computer into a platform for taking malicious action surreptitiously: spam sending, launch of Denial of Service attacks, malware distribution, etc.

 

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

 

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.

 

Sdbot.MAO 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.
  • 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.
