Instructor: Vivek Ramachandran

This course focuses on teaching the basics of 32-bit assembly language for the Intel Architecture (IA-32) family of processors on the Linux platform and applying it to Infosec. Once we are through with the basics, we will look at writing shellcode, encoders, decoders, crypters and other advanced low level applications.

A non-exhaustive list of topics to be covered include:

Computer Architecture Basics

IA-32/64 Family

Compilers, Assemblers and Linkers
