The team at the NSA has announced the 2021 Codebreaker Challenge is now live! To get started, head over to and sign up with your school email.

In this year’s challenge, you’ll detect and respond to a compromise in a Defense Industrial Base company’s network. Each task in this year’s challenge will require a range of skills. Network forensics, reverse engineering with Ghidra, vulnerability analysis, and exploitation are all in scope. You will need to call upon all of your technical expertise, your intuition, and your common sense.

New this year, the competition is piloting a Discord channel, giving access to a Community of Practice to help you get started. They will also host two technical talks this fall, giving competitors a chance to hear from some of NSA’s experts. Stay tuned!
