Welcome to my Capture The Flag (CTF) writeup collection repository! This repository serves as a compilation of solutions, explanations, and insights from various Capture The Flag competitions that I've participated in. Whether you're a beginner looking to learn more about CTF challenges or an experienced player seeking new techniques and approaches, you'll find valuable content here.
Capture The Flag (CTF) is a cybersecurity competition where participants solve a variety of challenges ranging from cryptography, reverse engineering, web exploitation, binary exploitation, forensics, and more. The ultimate goal is to find hidden flags (usually strings) that are placed in vulnerable services or files.
This repository contains:
- Writeups: Detailed explanations of how challenges were solved, including step-by-step guides, code snippets, and analysis.
- Code: Any scripts, tools, or utilities used during the CTF challenges.
- Resources: Useful links, references, and additional reading material related to CTFs and cybersecurity.
Feel free to explore the repository and browse through the writeups to learn more about different types of challenges and their solutions. You can use the search feature to find specific challenges or topics you're interested in. If you have any questions or suggestions, don't hesitate to open an issue or reach out to me directly.
