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.
