Brief Description 

    

Lineage.LAP is a worm that spreads by copying itself, without infecting other files.

 

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

  • It terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.
  • It modifies system permissions in order to hide itself.

 

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

  • It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.

 

Lineage.LAP 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.
