As of August 2024, I have completed writeups for **53 challenges** across\n**6 competitions**.\n\n## List of Writeups\n\nEach writeup will also include specific information on the competition, including dates and my results.\n\n* [n00bzCTF 2024](https://github.com/rstacks/n00bzCTF2024-writeup)\n* [corCTF 2024](https://github.com/rstacks/corCTF2024-writeup)\n* [DownUnderCTF 2024](https://github.com/rstacks/DownUnderCTF2024-writeup)\n* [WaniCTF 2024](https://github.com/rstacks/WaniCTF2024-writeup)\n* [Season IV, US Cyber Open: Beginner's Game Room](https://github.com/rstacks/USCyberOpenSeasonIV-BeginnersGameRoom-writeup)\n* [L3akCTF 2024](https://github.com/rstacks/L3akCTF2024-writeup)\n\n## What is a CTF?\n\nA CTF (Capture The Flag) is a cybersecurity competition. Participants must retrieve text strings called \"flags\" by completing challenges in cryptography,\nreverse engineering, forensics, web exploitation, and more. Check out [CTFtime](https://ctftime.org/) for more information and to register for a CTF yourself!\n\n## Software and Tools\n\nHere is a short list of some of the tools I frequently use during CTFs:\n- [CyberChef](https://cyberchef.org/) for cryptography challenges\n- [dogbolt.org](https://dogbolt.org/) for analyzing executables for reverse engineering challenges\n- [Burp Suite](https://portswigger.net/burp/communitydownload) for web exploitation challenges\n- [Wireshark](https://www.wireshark.org/) for networking challenges\n\nI'm currently using an [Ubuntu 22.04](https://ubuntu.com/desktop) laptop, along with [Kali Linux](https://www.kali.org/) through [VirtualBox](https://www.virtualbox.org/).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frstacks%2Fctf-writeups","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frstacks%2Fctf-writeups","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frstacks%2Fctf-writeups/lists"}
