X86 Assembly Programming

Dive into the world of X86 Assembly Language and unlock the secrets of how your computer truly works! This course provides a comprehensive understanding of the 8086 and 80386 Intel Architectures, laying the foundation for deeper software comprehension.

You'll master the Stack, exploring its role in procedure calls – how functions operate and utilize the stack for data management. Learn practical techniques for allocating C data structures in memory and gain critical knowledge about stack overflow exploits employed by hackers. Understand how to protect your code against these dangerous attacks and secure your applications.

Explore the power of SSE Instructions and discover how to leverage them for enhanced performance. This course is perfect for anyone looking to understand the inner workings of computers, how compilation works, and how C code is transformed into executable instructions.

Through practical code examples and hands-on debugging with the Gnu Debugger (GDB), you'll gain invaluable skills. We'll dissect disassembled code to understand its functionality, covering all major X86 instruction types, including jump instructions, arithmetic instructions, and mov instructions.

The course culminates in a detailed examination of stack overflow attacks and robust strategies to prevent vulnerable code exploitation.

Prerequisites: A working Linux system and basic Linux knowledge are required. We'll guide you through the installation of GDB and the process of converting C code to assembly for effective debugging. A comprehensive overview of GDB commands will be provided.
