The website is always Hacked. there is a website written in dedecms, and the version show is old, a few years ago. It is always hacked. I used to upload ASP files. I disabled ASP execution files in IIS. However, hackers can still modify the homepage file. I have disabled the permission to write and modify the website directory, and the result still does not work. I am still a newbie on the server. please give me some advice. thank you. ------ solution -------------------- the dead sheep will not be able to fix it-no program vulnerabilities will be supplemented, and all websites will always be hacked.

The dead sheep do not make up for it ――

Programs that have vulnerabilities are useless.
------ Solution --------------------
If it is Zhimeng (do not drag it online), it is simple and simple. Save the database, images, and upload documents, delete all the original programs, and then download and install the latest version.
