Brief Description 

    

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

 

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 affects productivity, preventing tasks from being carried out:

  • In the affected computer: it converts the computer into a platform for taking malicious action surreptitiously: spam sending, launch of Denial of Service attacks, malware distribution, etc.
  • In the local network: it generates a large amount of network activity and consumes bandwidth.

 

It reduces the security level of the computer: it opens one or more ports to allow remote access to the computer and takes action that compromises user confidentiality; it awaits remote-control orders received through IRC; it changes system permissions, decreasing the security level.

 

Sdbot.HPF 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.
  • 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.
