About GreatBinary.Win
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.
