The collection is intentionally pragmatic: small, self-contained puzzles you can run locally (Docker is provided), iterate on, and learn from.

The repository contains 20+ challenges across four categories:

  • pwn: the largest category — small networked binaries and local pwn problems covering memory corruption, information leaks, non-standard allocators, and ROP-style exploitation.
  • reversing: reverse-engineering puzzles and binary-analysis tasks.
  • misc: utility and puzzle-style problems that do not fit the categories above.
  • crypto: a small, crypto-related puzzle.

All challenges ship with simple infrastructure to run them locally: Dockerfiles, a compose profile, solver scripts, and a short README. The repository README includes quick-start hints.
