what is dns hijacking and how to avoid it

The internet offers many facilities to users, but it can turn pretty ugly in the blink of an eye. There are many factors that come into play. The most dangerous thing, though, is the common internet users’ lack of knowledge. This drawback is routinely exploited by malicious users to have fun at their expense.  This is why we will tell you about DNS hijacking. We will help you learn what is DNS hijacking and how you can avoid it.

What is DNS?

The first thing to be done is to understand what DNS is. Just like your computer, every website on the internet has a numerical IP. When you enter the name of a website in your browser, your DNS server looks up that IP corresponding to it. This process is recursive, but once the IP address is found, you are directed to the target website.

Basics of DNS Hijacking

We now know what role DNS servers play in your using the internet. DNS hijacking is an instance of the default DNS servers being changed. This means that the request to look up the IP of the website whose name you entered goes to someone else.

DNS hijacking occurs when a malware in your system switches the default DNS server with a different, possibly malicious one. Since this server is now responsible for directing you to website, it takes benefit of this power. It leads you to malicious and dangerous websites. These websites can in turn contain more malware, attempt to steal your identity, or use your system to infect others. Once your DNS server is hijacked, what websites you visit isn’t entirely up to you.

How to prevent DNS Hijacking

As we have mentioned above, DNS hijacking is possible when your system is already infected with malware. Therefore, it’s vital that you prevent that from happening in the first place. There are a number of ways you can do that.

  1. Firewall

A firewall is the first line of defence against any dangerous website or traffic. On encountering possibly malicious websites, you firewall blocks the traffic and notifies you about the same.

  1. Good and updated Anti-virus

Anti-virus software help keep your system free from viruses and malware. A routine check can reveal if your system has any threats. Modern anti-virus software blocks dangerous software from being installed, and also come with a firewall. Make sure you keep your anti-virus updated.

  1. VPN

VPNs help you stay protected from malware on the internet. They don’t help you in the way anti-virus firewalls do, but they prevent you from being harmed due to your location or identity being compromised. When you use a VPN, you are anonymous, and your activity is confidential. You are hidden behind the VPN server, and the data you share is protected by one or more layers of encryption. VPNs like hide.me offer great encryption and a good number of servers in different locations to choose from.

Now I hope you learn what is meant by DNS hijacking and how you can protect yourself from it. The steps mentioned above can help you be safe from it. In addition to them, you should always be careful when using the internet. Always be wary of suspicious emails or links on other websites.
