New to Reverse Engineering? Start Here.
Welcome! The world of malware analysis and reverse engineering can seem daunting, but every expert was once a beginner. This page is your roadmap.
The goal is to build a solid foundation. Don't rush. Spend time understanding each concept before moving to the next. Here's a suggested learning path:
1
Understand the Fundamentals
Before you can run, you must learn to walk. Focus on computer architecture, operating systems, and networking basics.
2
Learn Assembly Language
This is the language of the machine. You don't need to be a master developer, but you MUST be able to read it. Our Assembly 101 series is the perfect place to begin.
- Start with: Assembly 101: Your First "Hello, World!" in NASM
- Then move to: x86 Assembly: The Stack Explained
3
Get Familiar with Your Tools
Your toolkit is your best friend. Install and play with essential tools. Learn their interfaces and basic functions.

Hello, I'm Leon Kayaliev — a cybersecurity strategist and reverse-engineering enthusiast. GreatBinary.Win exists for one reason: to make the binary world less intimidating and more accessible.
My journey started with a simple curiosity:
"What actually happens when you double-click an .exe file?"
That question pulled me into the world of assembly, disassembly, and malware analysis. Over time, I've gone from breaking things apart to teaching others how to do the same — responsibly, and with a focus on building stronger defenses.
What You'll Find Here
This blog is where I share what I've learned:
- • Clear explanations of low-level concepts like the stack, registers, and APIs.
- • Walkthroughs of real malware analysis cases.
- • Practical insights for developers and defenders who want to understand what's really happening under the hood.
It's not meant to be a polished textbook. It's a living document of my own learning process, with all the detours, "aha!" moments, and ongoing discoveries that come with it.
