What are mirror websites and malicious images?
Mirror website refers to putting an identical website source program on several servers, each with its own independent URL, and these servers are mirror websites for each other. It is not very different from the main station, or it can be regarded as a backup measure for the main station. The advantage of having an image website is that if you cannot access the primary site normally (for example, a server dies or an accident occurs), you can still browse through other servers normally.
Malicious image refers to the process that someone directly resolves someone else's IP address through domain name A record, so as to get an identical website in the eyes of visitors. When the website is maliciously mirrored, the traffic of the mirrored website has been diverted to the website that the black station jumps. If the image is serious, other pages will also be mirrored, in the form of clicking its page to jump to other pages that you do not know.
What are the specific hazards of malicious images?
The malicious mirror intends to use its own domain name with a certain weight to intimidate the search engine to confuse the newly established website. It cannot distinguish the true and false domain names that exist and are resolved at the same time, and does not know how to choose. Some search engines are relatively mature in technology and can distinguish between true and false, but you can't guarantee that all search engines can give you the correct choice. You may also choose the domain name of the malicious person and delete the domain name of the original webmaster. At the same time, many webmasters who met this situation may also be novices, and they don't know how to deal with it, and finally let the malicious people get the hang of it.
As for what the malicious person will do after he wins? We can only speculate. However, in any case, it will have a negative impact on your website. The mirror website may bring some traffic to your website, but do not be thankful for it, because the mirror website will bring traffic and also take away your users. While the search engine is confused, users will also be at a loss, not knowing which is true and which is false. If the malicious person's domain name or other parts contain sensitive and unhealthy information, the victim's IP may also be blocked.
Solution to prevent websites from being maliciously mirrored
Independent IP is a prerequisite for a website to be maliciously mirrored. Secondly, the website program located in the root directory of the website space is also a condition for encountering malicious images. These two conditions are met, and malicious images are extremely simple for operators. Finally, malicious images often occur at the beginning of website establishment, because new websites are often valuable websites with content, and new website search engines have no weight, which is prone to black dragon events; On the other hand, the technology and insight of the webmaster of the new station are not enough, and the malicious mirror thinks there is an opportunity.
After understanding the principle of mirror website, let's talk about how to prevent your website from being maliciously mirrored. One is to change the IP address or space. This method is not very desirable, because if you change the IP address, others can easily find it; The second is to change the location of the website program from the root directory to the first level directory. This method is only useful for spaces that support secondary directory binding; The third is to prohibit direct IP access, which can be solved by contacting the host company; Fourth, add the base tag in the head area of the webpage to define the preferred domain name of the website; Fifth, the website program uses an absolute address, so that even if someone mirrors your website, opening a new page will still jump to your website; Fifth, reflect to the search engine. Google webmaster tool has the option to customize the preferred domain name, Baidu can also submit a manual complaint; Sixth, prohibit the other party's IP from visiting your website. This method has limited effect.
No matter what you do, you should first mask the original IP address. You can use some CDNs to mask it. If you use VPS (Virtual Private Server) technology or the server can also be shielded through firewall and other related rules. If you use a virtual host, you can ask the host company to help with the shielding operation.
