NorthSec is the world's biggest on-site CTF, opposes 75 teams of 8 people trying to obtain the most points by capturing flags during an intense 48 hour-long competition (Fri-Sun).
The challenges typically cover a wide range of security fields (web hacking, networking, binary reverse engineering, data forensics, hardware & IoT hacking, etc.) but also physical security (lockpicking, impressionning, social engineering, etc.) and are available for every team on their own private contest network consisting of a simulated IPv6 only Internet running with more than 250 BGP routers, with challenges exposed on top, in a "Hack quest/scenario" type (it is not a red/blue type of CTF).
