## What it is
Nightmare is an open-source introductory course on binary exploitation and reverse engineering built around CTF challenges, with over 90 documented challenges and writeups. It is distributed as a repository of challenges plus a static mdbook site for reading the material.

## Use cases
- learn binary exploitation from scratch
- practice pwn CTF challenges with writeups
- learn assembly and reverse engineering basics
- study heap exploitation techniques
- find free alternatives to IDA for learning exploit dev
- prepare for CTF security competitions

## When to choose
- you want a structured, linear curriculum for learning binary exploitation
- you prefer learning by solving real CTF challenges with documented solutions
- you want free, open-source tooling throughout the course

## When to avoid
- you need advanced or up-to-date heap exploitation content (the author recommends Shogun instead)
- you are looking for a tool or library rather than educational material
- you need formal coursework or certification

## Facets
- artifact type: learning-resource
- maturity: stable
- function: security, reverse-engineering, developer-tools, documentation
- domain: security, education, tutorials, penetration-testing
- platform: cross-platform, python
- tags: binary-exploitation, ctf, pwn, reverse-engineering, course, writeups, assembly, exploit-development, linux
