DEFCON 201 Online CTF Practice Challenge — justCTF — December 20th~22nd
Welcome to the DEFCON 201 justCTF 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 Friday, from December 20th 3:00 PM EST to December 22nd 4:00 AM EST, we invite all DEFCON 201 Members, Attendees and Fans to help us hack the justCTF 2019!
NOTE: This is also happening DURING our DEFCON 201 Meet Up for December 2019! If you are in New Jersey and want to get the prepare and participate in-person for this CTF check out our meet up here:
