What does the domain name DNS hijack mean?

In the process of surfing the Internet, we have all encountered the inexplicable jump of web pages. The target website opened is not the original content, but jumps to unknown pages instead. Even if the end user enters the correct URL, it will be directed to jump to those malicious websites, or pages that could have been visited normally, and suddenly cannot be opened. This is DNS hijacking, also known as domain name hijacking.

What if the domain name dns is hijacked?

1. Contact the service provider to confirm whether the DNS resolution is correct.

If unknown DNS resolution is found, delete these records immediately and add the correct domain name DNS resolution record.

2. Modify the domain name management password and the website backend management password.

The phenomenon of being hijacked means that some of our information has been leaked, so it is necessary to modify all kinds of password information immediately. Passwords should be as complicated as possible, including numbers, letters, symbols, and letter capitalization.

3. Check whether the website is hung up, poisoned, etc.

If you have the technology, you should understand and check whether the website is overloaded and poisoned, causing the code to be tampered with. Clean up the problem pages and collect them.

If you don't know much about technology, you can submit a work order and ask the space cloud service provider to assist in the investigation. Like the technical expert, you can help the webmaster to conduct a systematic investigation of the website.

4. Search engine maintenance

After deleting all kinds of question pages, 404 pages will be generated, and these data need to be submitted to search engines, such as Baidu webmaster tool to submit dead chain.

5. Improve the security of the website

If the website has not been modified by HTTPS, it is strongly recommended to purchase a SSL certificate and upgrade the website to HTTPS, which will be much more secure. If it is a CVM, it is recommended to enable high defense services. For example, CVM has its own cloud network shield, which is enabled automatically by default, which can effectively defend against all kinds of attacks.
