Do not understand what are the methods of website hijacking prevention? In fact, it is not difficult to solve this problem. Let the editor take you to learn how to solve it. I hope you will gain a lot after reading this article.

There are many ways to hijack a website, but there are only two core methods, one is to insert code such as JS files into your site, and the other is called DNS hijacking, which is to transfer the page you want to visit to other illegal pages.

If your website has been hijacked, it means that your server has been breached, then you can only conduct troubleshooting, antivirus and other operations on your website server, which are beyond the scope of this article. What we are studying today is how to prevent website hijacking.

One of the ways to prevent hijacking is to deploy a SSL certificate for your website and upgrade it to a HTTPS website. HTTPS website can encrypt the page content of your website and effectively prevent website hijacking.

Prevent DNS hijacking

DNS hijacking is through the intrusion of DNS, so that the original content to visit site An is replaced by the content of site B. For example, users enter the www.domain.com site address to visit your site, but because it is hijacked, the content returned is not your site content, but some illegal web content.

HTTPS can just solve this problem. Because to visit the HTTPS website, the client browser will first get the SSL certificate of the website, and the SSL certificate must match the domain name of the site. If you visit the www.domain.com website address, you will get a www.domain.com certificate, the browser will verify that the domain name and the certificate are consistent, inconsistency will prompt an error. Then DNS hijacking will not work, because illegal websites cannot have the certificate of www.domain.com domain name, even though DNS hijacking can return a page content, but there is no SSL certificate, then there is no place to hide. HTTPS is a good way to prevent DNS hijacking, and DNS hijacking is generally effective only for HTTP websites.

Populate JS files

Another situation is to implant JS files, this method uses JS files to secretly visit the pages of illegal websites, execute the page code of illegal websites, so as to gain benefits. For example, through the implantation of JS files, to obtain the user's account password and other personal information.

HTTPS can also solve this problem. For sites with HTTPS, the page content references must all be HTTPS, and if there is an external reference to HTTP, the browser will find it and prompt the user that the page is not secure. Because illegal JS files are usually HTTP, it is difficult for these illegal websites to apply to become HTTPS sites. Then when the browser finds that external non-HTTPS resources are used in the page, it will immediately prompt the user that the page is not secure, and will block and prohibit unsafe content. In this way, HTTPS will play a good protective role.

How to upgrade to HTTPS website?

To upgrade the original HTTP site to HTTPS, you only need to buy a SSL certificate. Deploy the SSL certificate to your Web website server, and the original HTTP site can be upgraded to HTTPS site.

There are many SSL certificate agencies on the market, you can apply to them for SSL certificate, you can also contact us to apply for it, the following is the relevant price of SSL certificate on this website.

Thank you for reading this article carefully. I hope the editor will share the content of the website hijacking prevention method which is helpful to everyone. At the same time, I also hope you can support us, pay attention to the industry information channel, and find out if you have any problems. Detailed solutions are waiting for you to learn!
