CTF-Challenges - Capture the flag challenges

项目说明

Security CTF Challenges
=======================

In this repository you can find challenges from previous _capture-the-flag_ security competitions organized by the Probe.ly team. For now we're only adding challenges that were both opened and successfully solved by some team during a public event.

Feel free to use these in your own competitions either _as-is_ or as starting points for your own custom challenges, perhaps together with our competition dashboard.

Challenges are organized by category. Each challenge has a level of difficulty, indicated in each challenge folder name, and range from 100 to 400, where 100 is the easiest and 400 the hardest.

Each challenge has its own README.md file with the challenge context and installation instructions. The solution is in a separate SOLUTION.md file to avoid spoilers.

There is also a a in the repository's root. To have an en similar to the one where we test the challenges, install with and run up. This sets up a base en, so make sure to check each challenges' README.md for challenge-specific dependencies.

Disclaimer
==========

This isn't production code. All of these challenges have built into them on purpose. As they're one-off programs, they may also contain other random issues we didn't account for (if a team happens to discover one of these, it becomes part of the competition too).

Also, they're mostly using de services and we recommend you run them behind a reverse proxy such as nginx. Check the nginx directory in the repository for configuration examples.

Contributing
============

We encourage you to fork this repository and add your own challenges. If you'd be kind enough to submit a pull request, we would surely appreciate it.

Kudos to , and for helping de some of these challenges!
