The magic of eBPF III: Development playground

Introduction  At some point, we had to dive into developing programs in eBPF, and that time has finally come. In this post, we'll explore several different approaches to writing eBPF programs, including powerful tools like Cilium and BCC. I'll highlight the methods that I find most efficient and convenient, because as developers, our goal is to write code quickly and effectively, without unnecessary complications. So let's get straight to the point and see how we can streamline our eBPF development workflow.  I think I should clarify, my go-to method of coding eBPF programs is with Cilium and their bpf2go library. A spectacular and simple way of coding programs in kernelspace, with C like syntax, and a very comfortable way of adapting the userspace with Golang. It turns out that all you need to do that is the big brain of the people in Cilium. I won't spoil anything just yet, but keep in mind that all my tinkering with eBPF has been done with bpf2go .   I st

About

     Hi, I'm Mr RattleBrain, pleasure to have you here. I'm a computer science guy with a passion for Information Technologies, Telecommunication and Cyber Security, specially Network security.

    I've been studying, investigating and practicing with labs (virtual and physical) in this area for the past five years, which means I'm at the point of knowing I know nothing. I learned a lot of concepts in this years but I still got a ton of things to know and improve. Nevertheless, I have experience enough to teach a few things to beginners or intermediate students, so that's what I'll do.

    If you are like me then you find this IT world amazingly entertaining and full of nerdy things that make your friends question why are they friends with you in the first place. Then they remember that someone has to be the printer-fixer in the group so that answers the question.

    Here you will find anything ranging from tutorials on anything I can think of to walkthroughs of TryHackMe rooms to theoretical explanation of some hard-to-grasp concepts that might help you understand better the underlying system of a computer or network.

    I will try my best to keep things light and easy to read yet at the same time containing the most amount of information possible.

    Now we've been properly introduced, go ahead and dive deep into this blog but, most importantly, practice what you learn. Don't limit yourself to reading.

    Enjoy!

A Gentle Introduction to NASM: Why and How to Get Started

Introduction     As the title suggests, in this post we'll be discussing many things about Assembly language. This is a series I have been wanting to make for a while now. My experience with Assembly Languages started way back in 2018 when I was in College. There we had a particular subject called Computer and Network Fundamentals where we had to tinker with MIPS Assembly (talk about fundamentals). It was love at first sight.     Now it's been a few years since then, so my skills at programming with assembly language got a bit better (not by much though). In case there's anyone else in this world that would like to start writing a few programs with this wonderful technology, this post and most likely the few following are gonna be of great help, I hope. What exactly is Assembly Language?      All this talk about Assembly is great, but what exactly is it? I’m guessing most of you already have a basic understanding of what Assembly language is and how it funct

The magic of eBPF I: What is this?

 Introduction     This post has been mainly inspired because I've been tinkering with eBPF for the past few months, getting to know it works. Now that I have what could be consider "Solid" knowledge on the matter, I thought to share and tell my experience and the possibilities I foresee with this technology.     If I say that the technology world, especially IT, is in constant evolution and change I surprise no one however, it's been a long time since we get something so potentially game-changing as eBPF is. Originally, it was designed to filter network packets, but now has grown into an incredibly versatile and powerful tool that enables developers and security engineers to run sandboxed programs in the Kernel space.     I'm fully aware that the moment you read Kernel a shiver was sent down your spine, and if it's not the case, I'm glad to meet another fellow low-level enthusiast. Regardless, you shouldn't be scared of any of this. To you as a pro
