Brief Description 

    

Koobface.KG is a rootkit. These are programs used to hide files, Windows Registry entries or processes, either their own or those of other programs.

In this way, even when a user looks for these items on a computer, they won't be able to see them.

Rootkits have been widely used for malicious ends, to camouflage other programs on computers that have previously been compromised through other means.

There are certain examples of malware that use rootkits in order to go unnoticed on the computer they have infected.

 

It captures certain information entered or saved by the user, with the corresponding threat to privacy: email addresses; user's browsing habits.

 

It reduces the security level of the computer: it terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware; it changes the security settings of Internet Explorer, decreasing its security level.

 

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 terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.

 

Koobface.KG 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.
