Brief Description 

    

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

  • It uses techniques included in its code to hide itself while it is active.

 

Mhook 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.
  • It is dropped or downloaded to the computer by other malware specimens, for example: Bagle.JP.
