The internet is a crazy place. Not only do marketers and advertisers follow your every move, there are hackers and scammers lurking in the dark corners, ready to pounce on your personal information.
At least marketers and advertisers want to make money off of you. The hackers and scammers I’m talking about, on the other hand, just want to flat out steal your money by way of stealing your personal information.
And as much as I don’t want to admit it, these hackers are smarter than the average criminal.
They use clever tactics that try to trick you into clicking on something that has the potential to crash your system, spread malware and even steal your personal information.
What the heck is DNS Hijacking?
One of these tricks is known as a “DNS hijack.” Sound complicated? Yes, it’s a little bit tricky. Let me explain.
A DNS or domain name system is often called the phone book for the internet. It translates the names of websites, like Google.com, to an IP address, like 126.96.36.199. The communication between the two is critical in order to correctly direct your web traffic.
What these clever hackers do is insert rogue DNS servers so your traffic is directed to unsafe servers instead of the secure servers your internet service provider gives you.
This means cybercriminals can then redirect you to fake versions of the websites that you’re attempting to visit.
For example, if your router’s DNS settings have been hijacked, each time you visit your online bank’s website, you’ll be redirected to a phishing website instead.
Criminals can also use DNS hijacking to modify the ads that you see while browsing. Instead of the regular ads that you should be getting, they can be replaced with inappropriate or malicious ones.
This opens you up to a whole world where all your personal information is vulnerable and your system’s chances of getting infected with malware go up.
