Overview

MetaCTF CyberGames 2021 was our 7th annual capture-the-flag (CTF) competition and our largest event to date! The event was free and open to everyone, and it challenged participants of all skill levels to learn new cybersecurity techniques and skills covering a variety of topics such as binary exploitation, cryptography, forensics, reconnaissance, web exploitation, and more.

During the 48-hour CTF, hosted December 3-5, 2021, over 3,400 participants worked in teams of up to 4 to solve 66 different CTF challenges & hunt down 13 different bonus flags scattered throughout the competition. Every CTF challenge had at least one solve by the close of the competition. We had participants from all 50 states in the US, over 110 different countries, and over 400 universities from across the world.

Livestream

Throughout the CTF, we also hosted a livestream that included several talks, mini-games, and bonus flags. The livestreams are available for replay here:
