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 modifies system permissions in order to hide itself.

Lineage.KDV 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.
• File infection: it infects different types of files, which are then distributed through any of the usual means: floppy disks, email messages with attachments, Internet download, files transferred via FTP, IRC channels, P2P file sharing networks, etc.
