DNSsignal(.)com – Methods of Delivery

DNSsignal(.)com can be delivered by using a few methods. One of them is through third-party installations of bundled programs and freeware applications. Those installations can be set by default to put additional components in your PC without appropriate notice. Until you find out, the hijacker could have changed a lot of settings. To avoid such installations can be easily managed if you find Custom or Advanced settings to deselect the components.

DNSsignal(.)com could have other methods for delivering itself to your computer system and browsers. Usually, that occurs via an extension or an add-on, located in your browser applications. Another popular delivery method is with advertisements, such as banners or pop-ups. The hijacker could be spread with redirects and sponsored content on other websites. The websites can be partners of DNSsignal(.)com. The following browsers could be affected: Google Chrome, Internet Explorer, Safari and Mozilla Firefox.

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:

STF-dnssignal-com-dns-signal-browser-hijacker-search-main-page

DNSsignal(.)com is presented as a useful search engine, which supposedly provides better search results than others. There’s nothing of the sort – the hijacker’s search results are completely unrelated to the search query. The unwanted program can replace the homepage, search engine, and new tab of any browsers you have. It also has a desktop software equivalent. Judging by the name, it is possible on some compromised PCs for the desktop software of the hijacker to change DNS settings, similar to the ProxyGate(.)net Adware.

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.

Part of the whole information, which is collected from the site, is gathered by cookies and similar tracking technologies, too. Be extremely careful of what information you give with your search queries, when using the search of this hijacker. Also, be wary around links and third party content. Continue to read and see exactly how DNSsignal(.)com collects information from you what kind of information.

DNSsignal(.)com – Privacy Policy

The Privacy Policy of the DNSsignal(.)com site gives insight about what the hijacker service does regarding your privacy. You can read it on the domain of the hijacker. According to that policy, personally and non-personally identifying information may be collected but not sought outright. Additionally, you will find the following quote intriguing:

Any web sites that you click to from one of our Internet search results web pages have been developed by third-parties over which we exercise no control. Such web sites may send their own cookies to end-users, collect data, or solicit personally identifiable information from you. We are not responsible for the privacy practices or the content of such web sites, including such web sites’ use of any information collected when our end- users click through to such web sites.

So, in the above excerpt is written that any advertising, redirect links and similar content from third parties hosted on the hijacker’s site is not controlled by it. Interestingly enough, they say that any information they collect from you is not shared with third parties, but they urge you to read any additional site’s privacy policy – from the ones that have content on DNSsignal(.)com. That only means that additional information is collected from you directly by third parties and not stated what kind, in the privacy policy of the hijacker in question:

STF-dnssignal-com-dns-signal-browser-hijacker-search-privacy-policy

That policy states that the following information may be collected:
