Heavy Wizardry 101: Shellcodes, Backdoors, Droppers, and Worms

In hacker lore, heavy wizardry means code so close to the metal it feels like magic—crafted by those who truly understand how the machine works. Heavy Wizardry 101 is your apprenticeship in that art.

You’ll start with the foundations—computer architecture, memory, and the stack—before progressing to real-world programs: shellcode, backdoors, droppers, and worms (all built and tested in safe, contained environments). Each chapter provides complete, working code for four major architectures: x86_64, ARM, MIPS, and RISC-V, revealing the similarities and differences between them.

You’ll learn how to:

• Follow code from human-readable C down to raw assembly and opcodes
• Adapt tools across architectures for maximum portability
• Strip away compiler overhead to write smaller, faster binaries
• Work confidently without relying on fragile, cutting-edge tools that can quickly become obsolete or change with new versions

Whether you’re an aspiring hacker, a security researcher, or a systems programmer, this book will give you the knowledge to not just run tools, but create them and understand exactly how and why they work.
