How to protect a WP site?

Question

Information Security

Hello.

There was such a problem on the WP site:
- the following code is automatically added to .htaccess

- about.php, content.php files are added to the site root

- robots.txt is deleted

- also, in the search engine results, instead of my pages, there are some Chinese inscriptions in the snippet and click to redirect to home page.

Has anyone else experienced this, please tell me how they did it?
