Generally, they are trojans on webpages.
The most stupid one is to directly modify the generated index.htm file. Generally, you can add a <iframe> code at the bottom of the source code to directly view the source code. You can regenerate the homepage once;
Modify the template file and add the <iframe> code to the source code of the main file in the templets directory. All generated files are called and deleted;
<Iframe> the code is more concealed, not the header or the bottom. In a middle department, you can directly CTRL + F to find it;
The. js file is called and mixed in the middle of the Web page. Using most web pages, there will be JS calls as a cover. You can find them carefully;
5. A dedeajax. js file will be called on the template homepage, and the code will be added here;
The above are some common cases, and only the trojan code is deleted.
