From 0x90 to 0x4c454554, a journey into exploitation.
In the last few weeks I have been diving deeper down the rabbit hole of exploitation work and with a bit of work and time to prepare myself for the long run I compiled a set of areas to study in a course type layout. I hope my research will help others spend more time learning and less time searching.
Because I am doing this myself I may have missed 1 or 2 things and along the way I will add in anything I find to help with process. So let us both get started...
First off I want to thank the corelan guys for the help they have provided me so far in the process. They have been there for me through my learning with knowledge and help. Thank you!
layout: I will be posting in a hierarchical structure, each hierarchy structure should be fully understood before moving on to the next section. I will also post sets of Parallel learning topics that you can use to study in line with other topics to help prevent monotony. These Parallel areas will have a start and end mark which shows when they should be complete in perspective to the overall learning
Here is a PDF of the course to help keep track and understand the layout. Course_layout.pdf

Part 1: Programming
Parallel learning #1:(complete this section before getting to the book "Hacking Art of exploitation")
While going through the programming area I concentrate on core topics to help us later on with exploit writing. One area that is very good to pick up is some kind of scripting language. Listed below are some of the most popular scripting languages and ones I feel will prove to be the most useful.
Python: One of my favorite languages and growing in popularity python is a powerful language that is easy to use and well documented.
Wikibooks Python
http://docs.python.org/
onlinecomputerbooks.com
Ruby: If you plan on later on working inside of metasploit this may be the language you want to start with.
Wikibooks Ruby
LittleBookOfRuby
onlinecomputerbooks.com
Perl: An older language that still has a lot of use perl is one of the highest used scripting languages and you will see it used in many exploits. (I would suggest python over perl)
[book] O'Reilly Learning Perl

C and C++ programming:
It is very important to understand what you are exploiting so to get started let us figure out what we are exploiting. You do not need to go through all of these but when finished with this section you should have a good understanding of C and C++ programming.

X86 Assembly:
Ok now to understand what the computer reads when we compile C and C++. I am going to mostly stick to the IA-32(X86) assembly language. Read the first link to understand why. It explains it very well.

This is to help understand what we are programming in and the structure of libraries in the OS. This area is very important far down the line

Disassembly:
Dissassembly is not as much programming as it is what the computer understands and the way it is interpreted from CPU and memory. This is where we start getting into the good stuff.

Part 2: Getting started
Now that we have a very good understanding of programming languages and what the machine is doing we can start working on task at hand, exploitation.
Here I will start a lot of the learning in very much a list format and adding in comments or Parallel learning areas when needed.
