UHCTF Junior is a spin-off of UHCTF for younger audiences. Over the years we have made small efforts to make security and CTFs accessible to younger people: children, teenagers and families. We are now making this material public, so that anyone can reuse it.

Everything lives in one open repository: github.com/uhctf/uhctf-jr.

What you’ll find#

  • Challenges: reusable challenges, one folder each, with a README and a solution. Many work on paper or offline in the browser, and need little to no prior knowledge.
  • Events: complete event formats that pick challenges and describe the planning, materials and scoring.
