Brief Description 

    

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

 

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

 

Downloader.BUI 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.
  • File infection: it infects different types of files, which are then distributed through any of the usual means: floppy disks, email messages with attachments, Internet download, files transferred via FTP, IRC channels, P2P file sharing networks, etc.
