Brief Description 

    

Krap.AZ is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions: screenlogging, stealing personal data, etc.

 

Krap.AZ 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.
  • Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
  • Email: sending emails that include a copy of itself as an attachment. The computer is infected when the attachment is run.
  • Peer-to-peer (P2P) file sharing programs: it makes copies of itself with enticing names in shared folders belonging to these programs. Other users of this type of networks then voluntarily download and run the infected files.
  • IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
