CTF Writeups

Overview

This directory structure contains writeups for CTF (Capture the Flag) challenges and cybersecurity exercises.

Each writeup documents the analysis, tools, and solution steps used to solve a challenge, preserving the context of where and how techniques were first encountered.

Structure

Directory	Platform	Description
🧪 ctfd/	CTFd	Annual cybersecurity CTF challenges run internally at work
🎄 holiday-hack-challenge/	SANS	SANS Holiday Hack Challenge — free annual global cybersecurity event
🧩 immersive-labs/	Immersive Labs	Halloween-inspired CTF challenges and training lab exercises

Relationship to ctf-techniques/

Writeups in this directory structure feed the ctf-techniques/ reference documentation. When a challenge introduces a technique that is worth keeping as a standalone reference (e.g., a new tool, attack pattern, or protocol) it gets extracted and documented there in a reusable, challenge-agnostic form.

The writeups preserve the original challenge context; the techniques documentation distills the reusable knowledge.
