Welcome & Course Overview

Hey everyone, welcome to this course where we are going to build our own RAT, from scratch. This isn’t just a simple view of an existing tool; here, we will deep deep into the code structure and rule of things used to develop a proper RAT. If you’re here, it’s because you want to understand how these programs actually work and why they are used in the real world, whether it’s for offensive security, pen testing, or just learning how malware operates and how to detect it

We are not just going to make a simple remote shell and call it a rat; we are going to build something serious

They are used to maintain persistent access to systems, collect information, manipulate files, and much more. But they are also used by security analysts and red teamers to understand how a real attack works and how to defend against it. What you learn here will be useful whether you are on the offensive or defensive side because to defend against an attack, you have to know how it’s done

–  We will cover what makes a RAT truly functional, the internal structure of a well-designed RAT, some recommendations to make the RAT harder to detect and analyze, examples of famous RATs, and detection methods to understand how antivirus and security tools try to stop them

We will cover HTTP communication, thread execution, managing memory in discrete ways to avoid detection (like using VirtualAlloc), and a rootkit integration to hide the RAT’s presence

This will not be just a proof of concept, but something that could actually be used in a real-world scenario. Most importantly, we will understand every part of the code and every feature of the RAT. This is not just copy-pasting but learning how to build it from scratch

We’ll go deep into the code, analyze each function, and learn step by step what it takes to build a real RAT
