What are the common ways of DNS hijacking? How should webmasters and netizens deal with it?

DNS hijacking, also known as DNS redirection, is a form of cyber attack where the attacker alters the DNS settings, redirecting users to fraudulent websites that mimic legitimate ones. Here are common ways of DNS hijacking:

1. Rogue DNS Servers: Attackers might set up their own DNS servers and trick users into using them, either through phishing emails or by compromising routers.

2. Malware Infection: Malware can alter the DNS settings on a user's device, redirecting them to malicious sites.

3. Compromised Router: Hackers can compromise home or office routers, changing the DNS settings to redirect traffic.

4. Man-in-the-Middle Attacks: Attackers intercept DNS queries and responses to redirect users to fake websites.

5. DNS Spoofing: This involves forging DNS responses to direct users to incorrect IP addresses.

How to Deal with DNS Hijacking:

For Webmasters:

• Use HTTPS: Implementing HTTPS ensures that the connection between the user and your website is encrypted, making it harder for attackers to intercept and redirect traffic.
• Monitor DNS Settings: Regularly check your DNS settings to ensure they haven't been altered.
• Use a Reliable DNS Service: Services like Tencent Cloud's DNSPod offer robust DNS management and security features to help prevent DNS hijacking.

For Netizens:

• Keep Software Updated: Regularly update your operating system, browser, and antivirus software to protect against malware that could alter DNS settings.
• Use a Secure Router: Ensure your router's firmware is up to date and consider using a router with built-in security features.
• Be Vigilant: Avoid clicking on suspicious links or visiting unfamiliar websites that could lead to phishing or malware infection.
• Use a VPN: A Virtual Private Network (VPN) can encrypt your internet traffic and help prevent DNS hijacking by using the VPN provider's DNS servers.

By taking these precautions, webmasters and netizens can significantly reduce the risk of falling victim to DNS hijacking attacks.
