64-bit Architecture

In the field of modern exploitation, it is essential to grasp the distinctions between 32-bit assembly and 64-bit assembly. We must understand 64-bit assembly to exploit modern systems.

This section will introduce you to 64-bit architecture and how the assembly differs from 32-bit assembly in a Windows environment.

You will understand the difference between 32-bit and 64-bit x86 CPUs, particularly the general purpose registers.

You will learn the 64-bit calling convention and how it is used how to call Win32 APIs, and that the caller is responsible for alligning and managing the stack when making Win32 API calls.
