Winko.AL 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.

Winko.AL 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.
