Challenge Writeups

This repository contains writeups of interesting security-, math- or IT-related challenges, wargames, and CTFs.
The topics will mainly cover:

• cryptography
• steganography & forensics
• binary exploitation
• machine learning
• logic
• reverse engineering
• web security
• networking

Structure

The writeups are contained in separate folders with names of the format year-month-[name of challenge event].
Note, that not all challenges per event do have a writeup. I try to particularly select a variety of interesting topics and difficulties.
