Hi,
I'm a Linux sysadmin with 15 years of experience and would love to help you with this project. I manage lots of Wordpress sites, so I'm used do harden servers like this one.
After restoring the backup, we tools like chkrootkit, rkhunter and clamscan should be installed to perform periodic checks. Also, all software (Apache, PHP, Wordpress) should be upgraded. Looking forward to hearing from you.
Best regards,
Marco Ramos
