NNS CTF 2025

Writeups and (soon) challenge resources for the NNS CTF 2025 event.

Submitting Writeups

Each challenge has its own directory under writeups in the following format: [primary category]/[challenge slug].

When submitting writeups, please create a directory using the following structure:

[primary category]/[challenge slug]/[team name]

Example structure, given the team "NNS":

- writeups
  - beginner
    - babyrsa
      - NNS          <- Your team name
        - solve.py   <- Solve script
        - README.md  <- The writeup itself
        - ...

For each writeup, please include a README.md and preferably a solve script (if applicable).
