There is a wealth of knowledge being passed in this easy to follow along book. Although some of the content (i.e. the source code), might seem cryptic at first, Tobias does an excellent job of going out of his way to making it understandable. In one instance, he was breaking down some assembly code and used pseudo c code to make it more understandable, and almost as if he could see my eyes still glazing over, he simplifies even further with pseudo code that was language-neutral (basically english), and then the light bulb went on. I was amazed at what I was learning. I also liked the fact that I did not have to concern myself or be distracted from the process because I did not understand some code, and that was huge. In addition, he has a lot of great visual diagrams, side notes, links to source code and the tools used, references for further study, basically the whole shebang. Simply put, Tobias made my first journey into the world of bug hunting an exciting one. I would highly recommend this to anyone who wants to better their programming skills, get into computer security research or just plain understand how software works this book will get you jump started and excited!
