DNS hijacking

People who use the internet in today’s world are exposed to a higher number of vulnerabilities than ever. Hence, it is important to understand how to deal with those vulnerabilities and overcome the risks that we may have to face. 

One of the biggest threats that you will need to be aware of is DNS hijacking. It can lead you towards numerous negative consequences as your computer system will get hijacked.

What is DNS hijacking?

Before you learn about DNS hijacking, it is important to understand what exactly DNS is clearly. DNS refers to the Domain Name System. It is made out of a system containing directories that link the different websites to their IP addresses. 

Imagine a situation where you are accessing a specific website via your computer. You will access the browser and enter the URL of the website. Then the browser will be sending that URL into DNS. This will be called a DNS request. Upon receiving the DNS request, it will send out a response. This is where your internet browser will be able to receive the IP address associated with the website. The IP address refers to the exact location of a website on the internet. Through this IP address, you will be able to access a website located on the internet. 

During the DNS hijacking process, the attacker will use intercepted queries of DNS to redirect visitors to malicious websites. In some of the instances, you will be redirected to pop-ups as well. Not just the cybercriminals are responsible for leading people towards DNS hijacking. Your internet service provider will also be able to DNS hijack you. This is often being done to redirect you to their promotional web pages. You must have come across this when you are accessing the internet to get work done in the day to day life.

This is the main reason why many people and even companies end up becoming victims of DNS hijacking as of now. You should keep this fact in mind and take appropriate measures to ensure your protection against DNS hijacking.
