Brief Description 

    

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

 

It captures certain information entered or saved by the user, with the corresponding threat to privacy: keystrokes, in order to obtain information for accessing online banking services, passwords and other confidential information.

It sends the gathered information to a remote user by any available means: email, FTP, etc.

 

It reduces the security level of the computer: it changes the security settings of Internet Explorer, decreasing its security level; it awaits remote-control orders received through IRC.

 

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.

 

Buzus.HP 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.
  • 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.
  • Computer networks (mapped drives): it creates copies of itself in mapped drives.
