DNS Hijacking, also known as DNS redirection, is a type of cyber attack where attackers manipulate the Domain Name System (DNS) to redirect users to malicious websites. The attackers achieve this by changing DNS server settings or intercepting communication between a user's device and the DNS server.

Types of DNS Hijacking:

1. Local DNS Hijacking: Hackers use trojans to replace the DNS server address on the user's computer, redirecting them to a malicious website.

2. Router DNS Hijacking: Attackers exploit vulnerabilities in router firmware to change DNS server settings, impacting all users connected to the router.

3. Man-in-the-Middle DNS Hijacking: Hackers intercept the communication between the user and DNS server, altering the server’s response to redirect users.

4. Rogue DNS Server Hijacking: Attackers directly compromise DNS servers to redirect users to fraudulent websites.

Mitigating DNS Hijacking Risks:

1. Use DNSSEC to encrypt communication between users and DNS servers.

2. Implement spoof detection tools and end-to-end encryption.

3. Regularly check devices for malware.

4. Frequently update router firmware and use strong passwords.
