How to repair a hijacked website domain?

In the Internet age, website domain names are crucial. Once hijacked, users will not be able to access the website, and even data leakage and brand image damage will occur. Therefore, when a domain name is found to be hijacked, it is extremely important to take effective repair measures quickly. The following will introduce in detail how to repair hijacked website domain names from multiple aspects.
1. Change DNS resolution settings: Domain name hijacking is often achieved by tampering with DNS records, so you should immediately contact the domain name registrar or DNS service provider to reset the DNS records to ensure that the request can be correctly resolved to the legitimate server IP address.
2. Enable HTTPS encryption: HTTPS can establish an encrypted channel between the client and the server to ensure data transmission security and resist risks such as man-in-the-middle attacks. When repairing a domain name, HTTPS encryption should be enabled first to enhance website security.
3. Install security protection software: To prevent future attacks, you need to install firewalls, intrusion detection systems (IDS) and other security protection software on the server to monitor network traffic in real time and block malicious requests. At the same time, update and upgrade these software regularly to maintain their effectiveness.
4. Check and repair the host file: Sometimes domain hijacking will modify the local host file (such as Windows' hosts file), so check whether the file has been tampered with, and delete or comment the entries pointing to malicious IP addresses in time.
5. Configure routers and firewalls: It is also important to ensure that routers and firewalls are securely configured. Reasonably configure the router to limit the IP addresses and ports of communication to reduce the risk of being attacked. Regularly update router firmware and firewall rules to maintain security.
6. Strengthen domain name management: This includes regularly changing the domain name administrator password, limiting access rights, choosing high-quality domain name registrars and DNS service providers, etc., which can effectively reduce the risk of domain name hijacking.
In short, after discovering that the website domain name has been hijacked, the above measures should be taken immediately, including changing DNS resolution, enabling HTTPS encryption, installing protection software, checking host files, configuring network equipment, and strengthening domain name management, etc., to restore normal access to the website and prevent future attacks.
