Long story short, DirectionsBuilder is not harmful. The actual pitfall, however, lies in the tactic for driving traffic to the rogue page. Computer users get redirected to it because of the misdemeanor of an extension added to their preferred web browser. The add-on is cross-browser, so it supports Chrome, Firefox and Internet Explorer. The settings affected in the course of this attack include the homepage, new tab and default search – no matter what URL value the victim had chosen to apply for these, they will all be replaced with DirectionsBuilder without any authorization.
