Website hijacking: refers to when a user opens a URL, an advertisement page that does not belong to the website appears, or it directly jumps to a sub-page that is not a website to which the website belongs.

How are website hijacking problems detected?

IIS7 Website Monitoring

Check whether the website is hijacked, DNS pollution detection and other information.

Usually, website domain name hijacking will occur in the following situations:

1. Domain name analysis of browsed website

2. The browser that the user browses is hijacked

(Website browser domain hijacking, that is, when you open a browser to browse web content, this page will automatically appear a browser advertising news, in fact, the browser itself did not put any advertising, this is malicious use of others hijacked the browser, as long as the user opens the browser will pop up this advertisement)

3. ***RQ, implant some *** programs after giving QR to the websites browsed by users.

This is what we usually call ***RQ, hang horse, implant some parasite viruses on your website, etc., originally wanted to enter the "Li Kui" website, the effect entered the "Li Gui" website, such as: the original input is the domain name but jumped to www domain name, then this is **RQ, but there are also many people, use this to do gray optimization. For example, when you search for "Beijing fire door," then there will be a lot of similar web pages, and these are not the pages with the site itself, many are ***RQ after the main station, in his above hanging ** virus, parasite virus, etc., this thing will not last long, but will continue to reproduce updates, you may search this time, show you, the next time you search, it appears in another page of this site.

4. Hijacking by operators

Assuming that your page is not pan-resolution, nor is your website program violated by ***, then it is attributed to this "non-descript" hijacking, that is, the operator was hijacked, in fact, this is generally done by the black hero, but the risk factor is also relatively large, this violation is very serious, and the general ** will not adopt such a method.
