DNS hijacking is a type of cyberattack that is becoming increasingly prevalent. It is a malicious attack that targets the Domain Name System (DNS), which helps your computer connect to the websites you visit. This attack can put your data, finances, and identity at risk. In this article, we'll explore what DNS hijacking is, how it works, real-world cases, and how to protect yourself against this type of cyberattack.
DNS hijacking is a type of cyberattack that targets the Domain Name System (DNS), the system utilized to translate domain names into IP addresses on the Internet. It is a form of data theft and manipulation that can have severe consequences for users. DNS hijacking can be used for malicious objectives, such as redirecting traffic to malicious websites and stealing personal information, and for financial gains, such as redirecting traffic to sites that pay for clicks.
The term DNS hijacking has been around since the early days of the Internet. It can describe various attacks, from redirecting traffic to malicious websites to stealing personal information. As the Internet has developed and become more complex, DNS hijacking has become more sophisticated and dangerous. It is now a significant threat to online security and should be taken seriously.
DNS hijacking is a cyberattack targeting a website's Domain Name System (DNS). This system is responsible for translating domain names (such as www.example.com) into their corresponding IP addresses so that computers can access them. By hijacking this system, attackers can redirect traffic to malicious websites or steal personal information.
DNS hijacking aims to gain control of a website or network by manipulating the DNS records. Cybercriminals can do this by redirecting traffic to malicious websites, changing the website's content, or stealing personal information. Attackers can also use DNS hijacking to access a website's admin panel or other sensitive areas.
The most common type of DNS hijacking is DNS cache poisoning, which involves attackers injecting malicious data into the DNS cache. This data can redirect traffic to malicious websites or alter the website's content. Another type of attack is DNS tunneling, which involves attackers tunneling through the DNS to gain access to the website or network.
Mobile carriers manage their DNS platform to control the user experience, and it produces a lot of data for them.
DNS makes using the Internet a lot easier to use by not having to remember a website domain rather than IP addresses, and companies can change their IP address if under attack, but threats to DNS include the following;
All these methods had used to achieve the same result, to send you to a rogue web asset.
Let's say you request to go to bankofamerica.com, and the DNS request is hijacked and sent to a fake website where you enter your login credentials. While trying to figure out why you can't log in, the hacker has already collected your login information.
Hackers use this to gather login credentials, collect information about your device, and serve malware to hack you in the future - these refer to as Phishing. Or they serve you ads to generate ad revenue; this is called Pharming.
DNS hijacking works by manipulating the Domain Name System (DNS). The DNS is a database of records that translates domain names (such as www.example.com) into their corresponding IP addresses. Attackers use various techniques to gain control of a website or network by manipulating the DNS records. One of the most common techniques is:
DNS hijacking is becoming increasingly common, with several high-profile cases in recent years.
For example, in 2017, attackers hijacked the DNS of a popular website and redirected traffic to a fake website. The attackers could steal personal information, including credit card numbers and passwords, from visitors to the website.
In 2018, attackers hijacked the DNS of a cryptocurrency exchange and redirected traffic to a malicious website. The attackers were able to steal over $1 million in cryptocurrency from the exchange.
Another case occurred in 2019 when attackers hijacked the DNS of a large hotel chain and redirected traffic to a malicious website. The attackers could steal customer data, including names, addresses, and credit card numbers.
These examples show how dangerous DNS hijacking can be and how quickly attackers can access sensitive data.
If you suspect that your DNS has gets hijacked, there are several steps you can take to check. The first thing you should do is examine the DNS records of your website or network. If the records have changed, it could signify your DNS getting hijacked.
You should also check your website or network's traffic logs. If you notice any unexpected traffic or redirects, it could signal that your DNS gets hijacked. You should also check your website or network's security logs and look for any signs of malicious activity.
Finally, you should check your website or network's security settings. If your security settings have changed, it could signify your DNS getting hijacked.
The best way to protect against DNS hijacking is to take steps to secure your website or network. It includes using strong passwords, regularly updating your security software, and monitoring your website or network for suspicious activity.
It would help if you also used two-factor authentication for your website or network. It will make it more difficult for attackers to access your website or network.
It would help if you also used a secure DNS provider. It will ensure that your DNS records protect from manipulation.
There are several techniques attackers use to hijack DNS. The most common techniques are DNS cache poisoning, tunneling, and spoofing.
DNS cache poisoning involves attackers injecting malicious data into the DNS cache. This data use to redirect traffic to malicious websites or alter the website's content.
DNS tunneling involves attackers tunneling through the DNS to gain access to the website or network.
DNS spoofing involves attackers creating fake DNS records that redirect traffic to malicious websites or alter the website's content.
The best way to protect against DNS hijacking is to take steps to secure your website or network. These includes:
A few suggestions include the following;

DNS hijacking severely threatens online security and is becoming increasingly prevalent. It is a type of cyberattack that targets the Domain Name System (DNS), which helps your computer connect to the websites you visit. It uses for malicious purposes, such as redirecting traffic to malicious websites and stealing personal information, and for financial gains, such as redirecting traffic to sites that pay for clicks.
To protect yourself against DNS hijacking, you should take steps to secure your website or network, use two-factor authentication, and use a secure DNS provider. Keep your software updated, as outdated software can be vulnerable to attack.
By understanding DNS hijacking and how to protect yourself, you can keep your data, finances, and identity safe and secure. Protect yourself now and stay ahead of the cybercriminals.
