Wordpress: hacked by Typical Idiot Security
Anybody here has experience with following problem:
The file readme.html with text hacked by Typical Idiot Security appeared in several /public_html/ folders. Quite a few WP folders, but also in /cgi-bin/ and /.well_known/ and some that have no function.
I wonder what that is about. Obviously some hacker can place files on my shared cPanels host as they please.
Any suggestion? And how can I prevent that?
