This foundational module introduces the core concepts of x86 and x64 assembly language, the bedrock of reverse engineering and malware analysis. You will learn to identify and understand CPU registers, common instructions (MOV, PUSH, POP, CALL, RET, JMP), memory addressing modes, and the structure of the call stack. By the end of this module, you will be able to read and interpret basic assembly code, understand how high-level languages compile down to machine instructions, and build the essential mental model required for analyzing compiled binaries in tools like Ghidra or x64dbg.
