The first rule of The Rabbit Hole is to do your best. There is no need to fully solve all the challenges. Grab flags, kick ass and show us what you got!
The Rabbit Hole Challenge is a way for you to showcase your skills and apply for a job, or just to have fun! You are expected to solve technical tasks, which will demonstrate your skills, knowledge, and problem-solving abilities.
First, sign in with your email. You can then choose a display name for the scoreboard. Challenges are accessible without signing in, however submitting answers requires logging in.
Solving each challenge results in a small token called a flag, which are in the format
NIXU{...},
NIXU17{...} or
DNVCyber{...}.
Submit them on the corresponding challenge page.
Please do not break the challenge for others. We would also like to ask you NOT to publish a writeup of the current year's challenges before April.
