Brief Description 

    

Sdbot.HNV is a worm that spreads by copying itself, without infecting other files.

 

Sdbot.HNV prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).

Sdbot.HNV redirects attempts to access web pages of certain banks to spoofed pages, with the aim of logging information entered by the user in these pages.

Sdbot.HNV redirects attempts to access several web pages to a specific IP address.

 

Sdbot.HNV 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.
  • IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
  • Computer networks (mapped drives): it creates copies of itself in mapped drives.
  • Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
