The forum actually uses some JavaScript for Ajax functionality.
You can read it
here. And I think, the forum is built on open source forum tool named
PHPBB. jQuery is not been used though. There is a function in that to post data to server in javascript.
The forum is secured for Injections
They even check HTTP referrer to process any data received
They have good session management.
Recently someone tried d-DOS to take server down, in vain, ROFL. I think it'd be pretty hard to do anything stupid on application layer. Try on network layer. And remember, they're running on one of the safest Operating System
FreeBSD 6.2 OS. And only 2 ports are opened to public access, Port 80(HTTP) and 443(HTTPS) with nginx server. And they're not vulnerable for
SSL Heartbleed too.
Anyway, Good luck. Happy Hunting!
