Organized by the ReconVillage at Defcon 26, the event is a CTF competition with a CTF structure. Most of the challenges are OSINT oriented focused on the information gathering phase but may involve knowledge on other computer-related areas. Flags are always provided in the format flag:{myflag}.
Special thanks for the organizers of the event for deploying this kind of challenges to the OSINT community.
