I've created a comprehensive and complete WinDbg cheat sheet of the most general and useful extensions/commands which you'll be using regularly. I've added a few data structures to the list too. The list is organised by category, according to the different areas of debugging such as Memory or I/O.

Additionally, I've been attempting to convert my blog posts into a .DOC format which can be printed, unfortunately I haven't added any images to conserve space and ink. However, I have tried to construct the blog posts so you know which row or column to check; dd commands with the IAT/EAT post for example.

I may have created a small list of tools before, however, I would like to expand this list and provide some better descriptions for each of the tools listed. These tools are either completely free or have a limited free version which provides enough functionality for those like myself, who aren't professional security researchers, escalation engineers or get paid for doing reverse engineering/debugging. These tools can and are used by professionals and enthusiasts alike. If you have any recommendations then please add a link to the comments section. WinDbg - Reverse Engineering/Debugging This tool is my most favorite, it provides complete functionality for enthusiasts and is for free. There is a wide range of extension and commands for viewing data structures, memory addresses and call stacks. It can be used for both reverse engineering and debugging BSODs (Blue Screens of Death). There is good documentation for WinDbg for finding hidden rootkits, examining data structures and loo...

Computers are increasingly being used to solve mathematical problems, and are becoming more prominent in solving problems in Number Theory and Graph Theory, as well as, fields of Physics and Biology. However, computers have been used to create seemingly random numbers for either games or security purposes; these seemingly random numbers are called Pseudo-Random. They may seem random but in fact they aren't random at all. To illustrate the difference between a true random number and a pseudo random number, look a look at the two images I've taken from Bo Allen's blog: True Random Number Pseudo Random Number The difference is very obvious and thus highlights the key differences between a true random generator and a pseudo random number generator. A pseudo random number generator uses a mathematical algorithm, which is able to produce seemingly random numbers. A true random number generator uses methods which can't be predicted, and therefore are truly random. The randomn...

Graph Theory Related Concepts: Before explaining the concept of Red and Black Trees and some of the algorithm analysis related to Red and Black Trees. It's best to have a understanding of some basic Graph Theory, such as what is a tree and the colouring nodes (or vertices). Graph Theory is my favorite area of Mathematics, and has many applications in Computer Science and other subjects. Graph Theory is a very visual form of Mathematics, much like Geometry, and for those who enjoy those types of Mathematics may also enjoy Graph Theory. A graph G is a ordered pair (V,E), with V being the graph's set of vertices and E being the the graph's set of edges which connect each vertex. Most graphs will have this basic structure, and it's the connections within the vertices which give graph their interesting properties. Hypergraphs are very interesting type of graph in my opinion, and sit between the boundary of Set Theory and Graph Theory. I may talk about more in the future. Hy...
