Hello,
There are no security updates on the template or extensions used with this. A template has virtually nothing to do with security, it simply stylizes the site. It has no user protocols, database access features, file upload capability, etc. The same goes for extensions, most of our extensions are very basic. In fact this is the only security update we have ever had to do, so if you are using S5 Media Player V2 be sure to update:

The first thing you need to do is restore a backup of your site from before the hack, your host can assist you with that. Unless you do that you are vulnerable to another hack if the hacker installed a backdoor. That step is essential. Once you do that, update all software, and change all passwords. Take other precautions as well, like setting up an htaccess password for your administrator folder as well.
