The 2023 CYBER CAPTURE THE FLAG Competition (the “Competition”) is sponsored by Deloitte & Touche LLP (the “Sponsor”). Competition participants agree to be bound by these Official Rules and the decisions of the Sponsor and the judges, which are binding and final on matters relating to this Competition. The Competition is subject to all applicable federal, state and local laws. Void where prohibited by law.

The objective of the Competition is to solve practical cyber challenges in a simulated environment. The goal of each challenge is to find a “flag,” which is a string of text. The flags for each challenge are submitted to the Administrator on (“Competition Website”) in order to receive points. Challenges award varying amounts of points depending on difficulty. The participants with the most points at the end of the Competition wins. The scoreboard is automatically updated to reflect the current state of the Competition. The scoreboard will reflect the final rankings when the Competition ends. In the event of a tie for points, the fastest participant wins. Competitors can participate either virtually or in-person.
