Hi,
I have multiple subfolders on my webserver which can be accessed like this:
mydomain.com/wpinstallation1
mydomain.com/wpinstallation2
Somehow there is a Folder called "MondoKing" in every root directory which has over 6000 html files with Japanese/Chinese content. Is there a security issue with WordPress or something or how did all of this get there? Every folder on my FTP Server is on 755 permission and files on 644.
There is also a js file which leads to a website which is on scamadvisor:

How is it possible that they uploaded these files to my server? I mean they are just html, js and sitemap files so no php as far as I see.
