how to detect dns hijacking

DNS hijacking, also known as DNS redirection or DNS spoofing, is a type of cyber attack where a hacker redirects a user’s legitimate DNS requests to a malicious website. This allows the attacker to steal sensitive information, such as login credentials, financial data, or install malware on the victim’s device. It is a serious threat that can have severe consequences for individuals and businesses alike. In this article, we will explore the different aspects of DNS hijacking, including its detection methods, prevention techniques, and how to stay safe from this type of attack.

Understanding DNS

Before we delve into the details of DNS hijacking, it is essential to have a basic understanding of what DNS is and how it works. DNS, or Domain Name System, is a crucial component of the internet that translates human-readable domain names into IP addresses, which are used by computers to communicate with each other. For example, when you type in the URL of a website, such as “,” the DNS server translates it into an IP address, such as “,” which is the actual location of the website’s server.

DNS hijacking occurs when an attacker manipulates the DNS resolution process, redirecting the user’s request to a different IP address than the one intended. This can be done by compromising the DNS server, modifying the DNS settings on the victim’s device, or by intercepting DNS queries and responses in transit.

Types of DNS hijacking

There are several types of DNS hijacking, each with different methods and objectives. Let’s take a look at some of the most common types of DNS hijacking:

1. Man-in-the-Middle (MITM) attack: In this type of attack, the attacker intercepts the communication between the user and the DNS server, thereby gaining access to all the DNS queries and responses. The attacker can then redirect the user’s requests to a malicious website.

2. DNS Cache poisoning: This type of attack involves corrupting the DNS cache of a DNS server, replacing legitimate IP addresses with malicious ones. As a result, all the users of that DNS server will be redirected to the attacker’s website.

3. Dynamic DNS hijacking: In this type of attack, the attacker gains access to the victim’s dynamic DNS account and changes the DNS settings to redirect all the traffic to a malicious website.

4. Router-based DNS hijacking: This type of attack targets the DNS settings of a router, which can affect all the devices connected to that network. The attacker can change the DNS settings to redirect users to malicious websites.

5. Rogue DNS server: In this type of attack, the attacker sets up a fake DNS server that responds to DNS queries with fake IP addresses, redirecting users to malicious websites.

Detecting DNS hijacking

Now that we have a basic understanding of DNS hijacking let’s look at some ways to detect it. Here are some of the most common methods used to detect DNS hijacking:

1. Check for changes in DNS settings: One of the easiest ways to detect DNS hijacking is to check for any changes in the DNS settings on your device. If you notice any suspicious changes, such as a different DNS server or IP address, it could be a sign of DNS hijacking.

2. Monitor network traffic: By monitoring network traffic, you can identify any unusual DNS queries or responses that could indicate a DNS hijacking attack. This can be done using network monitoring tools or by analyzing the DNS logs.

3. Use DNSSEC: DNSSEC, or Domain Name System Security Extensions, is a protocol that adds an extra layer of security to the DNS resolution process. It uses digital signatures to ensure the authenticity of DNS responses, making it difficult for attackers to manipulate the DNS.

4. DNS reputation services: There are several DNS reputation services available that can help detect malicious DNS activity. These services monitor DNS queries and responses and flag any suspicious activity.

5. Check for website redirects: If you are being redirected to unknown or malicious websites, it could be a sign of DNS hijacking. Keep an eye on the URLs of the websites you visit and make sure they match the ones you typed in.

Preventing DNS hijacking

Prevention is always better than cure, and the same applies to DNS hijacking. Here are some preventive measures that can help you protect yourself from DNS hijacking:

1. Keep your software up to date: Make sure you are using the latest versions of your operating system, web browsers, and other software. Software updates often include security patches that can protect you from known vulnerabilities.

2. Use a reputable DNS server: Make sure you are using a reputable and secure DNS server. You can either use your internet service provider’s DNS server or opt for a third-party DNS service, such as Google Public DNS or OpenDNS.

3. Enable DNSSEC: As mentioned earlier, DNSSEC adds an extra layer of security to the DNS resolution process. Make sure to enable it on your device and your DNS server if possible.

4. Keep your router secure: Make sure to change the default login credentials of your router and keep it updated with the latest firmware. Also, consider using a strong password for your Wi-Fi network to prevent unauthorized access.

5. Use a VPN: A virtual private network (VPN) can encrypt your internet traffic, making it difficult for attackers to intercept and manipulate your DNS requests. It also hides your IP address, making it harder for attackers to target you.

Staying safe from DNS hijacking

In addition to the preventive measures mentioned above, here are some general tips to help you stay safe from DNS hijacking:

1. Always check the URL of the website you are visiting, especially if you are asked to provide sensitive information such as login credentials or financial data.

2. Be cautious while clicking on links in emails or messages, as they could be phishing attempts that lead to a fake website designed to steal your information.

3. Use two-factor authentication (2FA) whenever possible, as it adds an extra layer of security to your online accounts.

4. Regularly monitor your financial accounts and credit reports for any unauthorized activity.

5. Educate yourself and your employees about DNS hijacking and other cybersecurity threats, promoting safe online practices.


DNS hijacking is a serious threat that can have severe consequences for individuals and businesses. Hackers can use this attack to steal sensitive information or install malware on your device. However, by understanding how DNS hijacking works and implementing the preventive measures mentioned in this article, you can protect yourself and your organization from this type of attack. Stay vigilant, keep your software up to date, and follow safe online practices to minimize the risk of DNS hijacking.
