My site is hacked for five days already and have no idea what to do. I tried to access the files through cpanel and found out that all my sites (P.S. this is a shared hosting) have been modified lately and all were hacked. I was about to perform a backup but then some of the files like wp-content were all missing. Is there any way I can still recover those sites? I already contacted my hosting provider but they haven't responded yet. What other measures can I do? Thanks in advance!
