Pretty much all my sites were hacked this week. Pain in the ass! How to resolve without deleting everything?

1. Log into your CPanel and change the master passwords
2. Log in to your main FTP account
3. Check your wp-header file, usually the usernames and / or passwords have had jiberish inserted into them. Edit.
4. Check your wp-login.php file, can’t find it, that’s because it has been deleted. Open your initial WordPress install folder and copy the file from your local machine to your WordPress folder on the server.
5. Login to WordPress Admin, can’t login > Click Forgot password to have a new password sent.
6. Reset password and login
7. Upgrade WordPress
8. Remove any users other than your own
9. Change your password
10. I would delete the Theme used, re-download and re-install or delete and restore a backup from a week before (or the day before the hack occurred).
11. This should do it. If your landing page has a big F**K you sign, they’ve edited the index.php of the theme, edit or replace with a new one.
12. You’re back in the game, no panic required.
