Learn assembly language and its role in turning your code into a safe, optimized running application

[b]What you'll learn[/b]

Write and understand x86 32bits assembly languge (Core Intel 80386 Instruction Set) and more

Understand at the most fundamental level mechanisms of higher level languages (pointers, variables, memory allocation, function calls, instructions)

Understand the build process behind GCC compiler - preprocessing, compilation, assembly, linking

Manually generate executables from projects containing source files, object files and libraries

Understand what happens at runtime (when application is launched into execution) - loader, shared libraries, process address space

Understand how hardware resources are used by a running process - CPU, registers, RAM, cache

Master debugging a program using extensions of GDB debugger

Reverse-engineer a binary using both static and dynamic analysis tools (objdump, Ghidra, GDB peda)

Exploit or protect against some of the most popular code vulnerabilities: buffer overflow

Understand and use mechanisms of protection against exploits (ASLR, Stack Smashing Protection, Data Execution Prevention)

[b]Requirements[/b]

Computer (x86_64 architecture recommended)

Basic C programming knowledge would be helpful, but not mandatory

Being accustomed with the Linux operating system would be helpful, but I will walk you through everything you need - virtual machine, terminal, VSCode

[b]Description[/b]

This course presents in a simple manner the assembly language - intel syntax - for the x86 32-bits architecture and places this in the context of a computing system. We start with a short presentation of the hardware components on which assembly code is highly reliant, how they work and what is their purpose in relation to the software. We continue with some higher level notions - data, variables, pointers, functions - as we understand them in languages such as C/C++ and we show all the steps that lead to the assembly language. By using a lot of demos and animations, we go through all the assembly language notions - registers, static memory, the stack, function calling, instructions - side by side with the more familiar concepts in higher level languages. In this process, we make use of multiple tools, both for static and dynamic analysis of binaries: GDB, objdump, nm. Towards the end, we touch on the security side of assembly. We do a deep dive into one of the most common vulnerabilities, buffer overflow and show how programs can be exploited. While on this topic, we present a binary analysis tool that is the bleeding edge in the domain of security: Ghidra.This course is for people of any level and is the direct result of a desire to explain the concepts that were most useful to my career path in the simplest manner.
