Challenges

These are the challenges used in the 2019 OpenCTF put on by Neg9 at DEF CON 27.

Challenge Structure

The source for each challenge is fully contained within its own directory. Each challenge has a common structure, and the top level items of that structure are described below.

Item	Description
README.md	Contains name, category, description, and final point value of the challenge.
flag.txt	Contains the flag so that anyone wanting to check the flag without finding the solution can do so.
dist\	Contains the files that were distributed on the scoreboard to players during the event.
src\	Contains the source for anything used in the challenge that wasn't distributed during the event.
SOLUTION.md	A natural language write-up of how to solve the challenge.
solution/ / solution.* / solve.*	(Optional) Directory or single-file with a codified solution to the challenge. Sometimes these are hiding within the structure somewhere.
Dockerfile	A Dockerfile which will create an image that runs the challenge in the same manner it was deployed during the OpenCTF event.
