Domain name hijacking refers to hackers or malicious attackers modifying domain name resolution records or attacking DNS servers to direct legitimate domain name resolution to malicious IP addresses or websites. In this way, when a user enters a hijacked domain name, the actual website they visit will be a maliciously controlled website, thereby causing the user's privacy to be leaked, data to be stolen, or suffer from other security risks.

The following are some common measures to prevent domain name hijacking:

1. Choose a reliable domain name registrar: Choose a domain name registrar that has been verified by reputation and provides reliable and secure services to reduce the risk of domain name hijacking.

2. Use DNSSEC: DNSSEC (Domain Name System Security Extensions) is a security extension technology that can be used to verify the authenticity and integrity of domain name resolution and prevent DNS hijacking attacks. Enabling DNSSEC can provide higher domain name resolution security.

3. Use secure DNS resolution services: Choose service providers that provide secure DNS resolution services. These service providers may use stricter security measures to protect the domain name resolution process and reduce the risk of domain name hijacking.

4. Regularly check domain name resolution records: Regularly check domain name resolution records to ensure that the resolved IP addresses and related configurations have not been illegally tampered with.

5. Strengthen server and website security: keep servers and websites safe and updated, and use technical means such as firewalls, intrusion detection systems, and security encryption protocols to prevent hackers from intruding and tampering with domain name resolution.

6. Use HTTPS protocol: Enable HTTPS encryption for the website to ensure the security of communication with users and prevent sensitive data from being stolen when the domain name is hijacked.

7. Pay attention to security awareness education: improve the security awareness of employees and users, educate them to be vigilant against phishing websites and malicious links, and avoid domain name hijacking attacks.

To sum up, taking comprehensive security measures, including choosing a reliable domain name registrar, using DNSSEC, using secure DNS resolution services, regularly checking resolution records, strengthening server and website security, etc., can effectively reduce the risk of domain name hijacking.
