While my website has been online for over 5 months and working properly, yesterday 28/1 it was hacked. I tried to access the homepage and some of the pictures didn't even load and the website was slower than ever. Afterwards, I tried to access the wp-admin and it was redirecting to a blank page of a website called "coverskin.ir". I tried the same thing with other pages and I had again the redirect issue. I edited the htaccess file, and then the redirect issue was solved but the homepage, buttons, pictures, were broken and nothing changed. That webpage was again in chro. Anyway, I restored the website's and database's back up from 26/1 and nothing happened. Then I tried from 24/1 and I had the same result and finally, I tried from 16/1 and everything remained the same without any change. Sometimes the website loads but it does slower than usual, there are requests for coverskin.ir and the admin bar isn't at the top of the page.
The suspicious website is coverskin.ir.
My website is alienage.gr
