Event organizers 

The United States Air Force and United States Space Force jointly present this year’s Hack-A-Sat, which is open to all cybersecurity researchers who want to up their skills and knowledge of space cybersecurity. The challenge begins with a qualification round, and culminates in an attack/defend style Capture the Flag Event. It’s a space showdown designed to blur the lines between The Good and The Bad, and to focus all the best minds on creating a Cyber-Secure universe.
