I am Rafael Pimentel an offensive security professional. I started my computer security journey on 2020 and have taken extensive notes during this time. This page was created to share knowledge with the world.
These notes come from my personal Obsidian vault and my aim is to expand this public knowledge base as time goes on.
You are welcome to check my free course on using Obsidian for ethical hacking on my GitHub.
