Brief Description 

    

Adware refers to programs that display advertising using any means: pop-ups, banners, changes to the browser home page or search page, etc. The advertisements could be associated with the products or services offered by the creator of the program or by third-parties.

Adware can be installed in a number of ways, on some occasions without users' consent, and either with or without users' knowledge of its function.

 

It affects productivity, preventing tasks from being carried out:

  • In the affected computer: it displays pop-up windows.

 

It uses stealth techniques to avoid being detected by the user:

  • It uses techniques included in its code to hide itself while it is active.
  • It modifies system permissions in order to hide itself.

 

Startpage.DDE 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.
