    Hello :)

    You should ensure a firewall is installed to help deal with attacks on a basic level. However, depending on the nature of the DDOS attack, you may need to consult with your data center to see what type of solutions they offer for dealing with more complex attacks on your server. You can search "DDOS" on our forums to review discussions from other threads.

    Thank you.

    You should review the index file of your site (especially if it's a php file, index.php) for any injected code which may execute.

    Is the "start" variable a legitimate variable used by your application? Would a normal visitor ever hit a page with ?start=7985 or any other value? If not, you could use modsecurity to block the QUERY_STRING "start=" with a custom rule.
