How to Defend Yourself Against Rogue DNS Attack?

Rogue DNS Attack, also known as, DNS Hijacking is one of the most prominent types of DNS attack which has the potential to damage your servers extremely badly. This attack exploits the DNS server like no other kind of hack does.

In order to understand the seriousness of rogue DNS attack, let me first tell you what a DNS is and how important it is to protect it.

In the simplest terms possible, it is DNS which is responsible for executing every on-net activity you do. When you type a website in the address bar of your browser, the browser sends the website to the DNS server. The DNS server then filters out the IP address of the particular website and responds back to your browser with the required information. Thus, you have the website opened in front of you. Without DNS, there is no net surfing, no e-mails, no chats, and no watching videos on YouTube!

Enough of the fundamentals, get to the point!

Now that you know the importance of DNS, let me tell you how attackers are using the vulnerabilities of this very system to get your bank passwords, email passwords, and other confidential data!

DNS attackers are prominently using Rogue DNS servers to get inside your computers and operate them on behalf of you.

These rouge servers are the product of notorious DNS hackers who hack into your computers and change the DNS setting of your browsers. By changing the DNS settings, they are able to take control of your every internet activity.

How can they hack into my computer?

There are many ways by which your computer / device can be hacked and DNS settings can be changed in order to point the direction towards these Rouge DNS servers.

1. Malware Infected Sites: It should be no surprise top you if you have been using the internet for long. How many times have you come across a site which asks you to download a tool / toolbar / exe file etc.?

Well guess what? Chances are these tools are nothing but the custom created malwares by the attackers. By downloading the tools, you have opened the doors of hell for yourself.

However, not every site which asks to install tools is infected. The only way to differentiate between the two types of sites is by using DNS firewall.

2. Expired Certificate: Have you ever encountered a browser error stating the certificate of a particular site has been expired and in order to visit the site, you have to accept the bad certification anyhow? No, I am not saying that it has to be a DNS attack but there is a strong chance that if you accept the bad certificate, the DNS setting of your browser can be changed to the Rouge one.

How do I protect myself from Rouge DNS Attacks?

Assuming that you are not a victim as yet, the first thing you should do is to install a DNS firewall in your system. The DNS firewall protects your system / devices from getting hacked at the first place and you need not worry about Rouge DNS attacks.
