Hello

I have moved this over to the "Security" forum for you. You may want to consider consulting with a system administrator/security specialist. There are several listed at:

cPanel Application Catalog - System Admin Services

This thread also includes some advice that may be helpful to you:

Thank you.

First of all I would suggest you to check if there are PHPShells are present under your server also check complete root level security. Second thing I would suggest you to disable remote MySQL as a precaution.

Did you install chkrootkit OR rkhunter ? If yes, perform a check and see if it lists any rootkits.
