Reverse Engineering → Assembly & Architecture
Kernel mode code runs at ring 0 — the CPU's highest privilege level. Understanding the ring 0/ring 3 boundary, how SYSCALL transfe…
Modern compiled code uses XMM and YMM registers for both floating-point and parallel integer operations (SIMD). Recognising SSE/AV…
Everything in a CPU is bits. Understanding how bits encode integers, negative numbers, floats, and memory addresses — and how hex …
Reverse engineering is reading compiled machine code. To do it well, you need a mental model of what the CPU is actually doing: ho…
x86 assembly is the language your disassembler speaks. Every binary you reverse has already been compiled to x86 machine code — yo…
