Welcome to the June DEFCON 201 Facebook CTF Practice Challenge!

For over two years we have been planing running our own Wargames and CTF to help people develop their hacking skills. While progress is still being made (we plan to launch our own in Winter 2019), DC201 will also occasionally enter into various online CTF Tournaments to test our skills and to get a sample on how one is set up so we have a blueprint in creating our own.

This weekend, from May 31th 8:00 PM EST to June 2nd 8:00 PM EST, we invite all DEFCON 201 Members, Attendees and Fans to help us hack the Facebook CTF 2019!
