Forget waving wands – the real magic happens in assembly. Heavy Wizardry 101 takes you deep into shellcode, backdoors, worms and low-level hacking across x86_64, ARM, MIPS and RISC-V.

In hacker circles, ‘heavy wizardry’ means code that trades on intimate knowledge of a system – the kind that speaks its private dialects and bends its rules. Heavy Wizardry 101 teaches you to write it. Youll build shellcode, backdoors, droppers, and worms from scratch, working at the instruction level where magic happens.

Every project is implemented for four architectures: x86_64, ARM, MIPS, and RISC-V. Youll write the same program four times, seeing exactly what stays constant and what changes. Each chapter starts with architecture fundamentals, such as memory layout, calling conventions, and stack mechanics, then walks through complete working implementations on Linux in safe, contained environments.

Learn to:

• Write position-independent shellcode and programs that execute in constrained memory spaces
• Implement TCP reverse shells that bypass basic network restrictions
• Build executable droppers that embed and deploy payloads without detection
• Create self-replicating worms that propagate across networked systems
• Write basic port scanners to discover services in a network
• Port low-level code between architectures by understanding instruction-level differences

Whether youre a penetration tester who wants to stop depending on Metasploit, a security researcher analysing malware, or a systems programmer who needs to understand how computers work, this book gives you the skills to build and reason about code at the lowest level.
