Yes, WHMCS v5.2.3 is the safest and greatest version (aside from the Remember Me bug, which is eating my insides). If your hosted with HostGator, I know they have gone as far as changing the admin password via PHPMyAdmin and logging into my WHMCS to remove any bad files (no, I wasn't happy with the privacy breach). Safe to say that was a year or two ago.
