Lineage.KNK is a worm that spreads by copying itself, without infecting other files.
It reduces the security level of the computer:
it changes system permissions, decreasing the security level.
Lineage.KNK prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).
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.KNK does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
