How can I limit a directory accessibility to only itself?

Question

Here is the scenario:

I have a wordpress project which is blog of my main project. Apparently that wordpress project contains a malware which edits js files and modifies the value of href links. Sadly that malware is deployed over the whole root. I mean that malware works on the js files of the main project too.

Now I want to know, how can I make that wordpress project isolated? I want to limit accessibility of that wordpress project to only itself. To avoid publishing that malware (which exists in the wordpress project (which is a part of the main project)) in the whole main project?

I read somewhere, you can make a directory isolated on linux, like a different server. Any idea how can I do that?

If you want to have an isolated directory, you can use Chroot. That makes you able to isolating applications from the rest of your computer.

For this purpose, please read this article: BasicChroot.

Also you use chattr command for making a directory and its contents immutable, even with root access.

sudo chattr -R +i /path/of/your/directory

After run above command any users can [change/remove/append] that directory and its constents.

And for remove immutable flag from that files, you can uses below command:

sudo chattr -R -i /path/of/your/directory
