Introduction

My write-up and notes (Pwn & Reverse Only) while I was preparing to compete in some national CTF events. Writing notes helps me understand better when solving challenges, so I made this repository. All of the challenges here are mostly from public open-source CTF platforms like HackTheBox, pwnable, etc.

All the challenges here are easy level problems because I only want to learn the basics and concepts. Additionally, the hard-level challenges are too long to explain the Proof of Concept. Make sure you have read the basic of assembly for CTF here.
