Question

Have you ever had to work with a Wordpress site that was hacked?

Answer 1

I had made a test site, without security plugin (Wordfence)

The site was hacked.

I noticed that in Linux WEb hosting dir there were a few .<something> dirs, hiddend dirs, so

1. I deleted all hidden dirs & possible files
2. I changed the tables name from wp_<table> to wp_<something>_<table>
3. I changed with a plugin admin user name and set a new password.
4. I run checks of security, using plugins (compare with original installation, find problems e.t.c.)
5. I installed the security plugin WordFence

The site was ok after all these

Another solution RESTORE A FRESH GOOD BACKUP & CHANGE PASSWORDS & WORDFENCE
