DNS Unlocker – A Quick Background

This nasty software first appeared on the security radar during the autumn of 2014, associated with the keyword “Netflix DNS Unlocker”. The software has nothing to do with Netflix, although it claims to enable users who cannot access Netflix(online service for watching TV series and other shows and movies online) from their area to use it, by modifying their DNS settings. Instead, the program uses the DNS Settings it has modified to sniff out user information and display various advertisements of unknown origins to the user. Even though Netflix is available in many places today, there are still a lot of geo-restricted websites that may push users into looking for access from their location and hence making the mistake of installing DNS Unlocker by accident. These factors make the software still very eventful and widely distributed, generating its author’s profit.

How Is DNS Unlocker Spread

To be distributed, the program does not have a direct download link on its website. Instead, it is spread via other methods, such as third-party installers downloaded from sites that may provide different programs for free. Such programs may be older versions of widely used apps, media players, video recorders, video converters and other programs downloaded daily. Some websites may replace or add to the installation of the programs DNS Unlocker’s installation file which slickly enough installs it on your computer. Users often tend to miss such “bundled” applications when they install programs for one reason or another. Here is how DNS Unlocker may appear on the “Advanced” or “Custom” installation options of your computer:

Since DNS Unlocker and other PUPs (Potentially Unwanted Programs) like it are widely spread out across the web, users are strongly advised to read the End User License Agreement and always check for bundled applications. One particular software that may assist in “catching” such apps and may help to stop them is EULAlyzer which stops the installation if a specific keyword (for example bundling) is discovered. This makes it a very powerful tool in combination with a rich knowledge base and a recommended one if you want to detect adware or other rogue software slipping past you.
