I'm still in a hiatus at the moment, but I may write the occasional blog post now and again (during the hiatus) like in this example. I will be giving a brief insight into the concept of Qubits which is the analogue to Classical Bits (1's and 0's). The only real difference between the two types, is that Qubits can be manipulated and controlled by the laws of Quantum Mechanics such as Superposition and Quantum Entanglement; the Spin states are also of great importance here since the control of the Spin will help create strings of information which are studied in Quantum Information Theory. Before reading this post, I will assume you have some mathematical knowledge of Linear Algebra and Dirac Notation. Otherwise, I'll explain the concepts as a I write about the fundamentals of Qubits. Firstly, let's look at the concept of Spin. Spin is a very important concept for Qubits. Spin is the angular momentum of a particle intrinsic (property of itself) to it's body. Spin...

Instead of allowing my blog to completely go 'dead', I've decided to write a short post regarding my hiatus which is going to be used to improve of knowledge mathematics related to physics and computer science. The reason being is because I plan to finally go to University this September/October and study for a degree in Computer Science, and then eventually a Ph.D since I would like to research into the theory of Quantum Computing. To make things easier for myself and to give me an advantage when I do hopefully go to University, I feel it's better to learn the Mathematics beforehand since they are so crucial for a real understanding of the concepts in Theoretical Computer Science and Physics; Theoretical Physics is very mathematically orientated. At the moment, I'm doing Business at college which isn't exactly my intended career path, but I only chose the subject since the Mathematics courses and Computing courses (more like Microsoft Office) didn't teach a...

This is going to be a relatively long blog post, but I feel it may be useful since not much information is given on about how to find the IAT (Import Address Table) and EAT (Export Address Table) with WinDbg. There is some useful articles and blog posts on the subject, but I would like to add my own explanations and bring all the information together into one blog post. I'll start with a description of the purpose of the tables and their general structure. The IAT is simply a array of pointers which are loaded by the Image Loader. The IAT is used primarily as form of a lookup table, which is used to call function present in other library modules (.DLLs). Since the executable module will not the the know memory addresses of the libraries and it's stored functions, it brings the in the purpose of the IAT. The IAT slots will be written with memory addresses by the linker.  The IAT is part of a larger data structure called the _IMAGE_IMPORT_DESCRIPTOR, which also contains another l...
