Our first hungarian site is in english and has 50 levels/challs, which seem fun, well chosen and creative.
To make progress on hax.tor you have to solve the challenges in a linear order, 1 by 1.
All in all we got very good response for the challenges there, where quite a few are from the "exploit" section.
Also every registered user gets an instant shell account on a fast co-located Debian Linux box.
Unlimited subdomains, custom virtualhosts, procmail, TOR connection tunnel and gigabit connectivity.
Many thanks go out to its admin haxtor for implementing the needed scripts.
Happy challenging and have fun checking out the site !
