Cybersecurity CTF Challenges and Write-ups

This repository offers exploit scripts and write-ups specifically for Linux kernel CTF challenges, making it a focused learning resource for that niche, but it does not provide diverse challenge categories or an interactive environment.

smallkirby/kernelpwn is a focused collection of kernel-pwn CTF challenges with accompanying writeups, so it fits the category as a challenge-and-writeup repo, but its narrow single-topic scope and lack of an interactive environment or difficulty progression mean it covers only a fraction of the features you are looking for.

MBE is a deployable CTF wargame environment with structured binary exploitation labs and courseware, providing both challenges and educational materials that fit your search for a combined challenge and write-up resource, although it focuses narrowly on binary exploitation rather than offering diverse categories or explicit detailed write-ups.

This repository collects CTF challenges with mandatory writeups stored in readme.md files alongside source files, organized by category—exactly the combination of challenges and explanatory content you want for learning security skills.

This repository provides kernel-hacking CTF challenges, but it lacks detailed solution write-ups and covers only one specialized category, so it is a narrow subset rather than the broad CTF challenge and write-up repository you are looking for.

This repository provides CTF challenges focused on Linux kernel exploitation, but it does not include explanatory write-ups or cover a diverse range of categories as requested.

This repository stores personal CTF challenge solutions (write-ups) but does not provide the challenges themselves, so it lacks the interactive, self-hostable challenge environment you need to practice security skills.

Google CTF is a platform for deploying and scoring security challenges, but it does not include solution write-ups, so it only partially fits the search for a combined challenge and write-up repository.

fbctf is a platform for hosting live CTF competitions with scoring and orchestration, but it does not provide explanatory write-ups for learning, making it a competition organizer rather than a repository of challenges and solutions for self-paced practice.

CTFd is a platform for hosting CTF competitions, but it does not include explanatory write-ups or curated challenge content for learning, so it is a tool for running CTFs rather than a repository of challenges with solutions.

CTFd is a framework for hosting CTF competitions, not a curated collection of challenges with write-ups—it provides the infrastructure to run events but lacks the pre-built challenges and solution guides you're looking for.

Learn to Cloud is a cloud engineering courseware that includes some CTF practice labs, but its primary focus is foundational cloud skills rather than a dedicated CTF challenge and write-up repository for security learning.
