Brief Description 


Rabbit.M is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.


Rabbit.M accesses several websites to download files, which it then runs. These can be any type of file, although they are normally malware.


Rabbit.M 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.
  • IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
