DNSsignal(.)com – A Closer Inspection

DNSsignal(.)com is the main web domain of a browser hijacker. It is composed of a plain white page, a logo with a search bar below it, which are in a frame. You can see the page in the screenshot displayed below:

The unwanted program can replace the homepage, search engine, and new tab of any browsers you have. It also has a desktop software equivalent.

In the picture shown below this paragraph, you can view an example of the search results page of DNSsignal(.)com. Only one page of search results is displayed, even for the most popular searches. That would be enough if any one of those results were relevant to your search queries. You can see how the entire page is covered, from top to bottom, with sponsored content, advertisements, in the form of in-text, redirect links. All of your searches will be filtered by the hijacker and the gathered information sent to its servers.
