(This book is aimed at readers who are beginners in buffer overflow use; and take care of brothers who want to learn buffer overflow technology. The intention of this book is to use witty words and popular explanations to analyze the thinking and thinking of Windows buffer overflow programming in detail; There is no monotonous, large assembly code explanation in this book; there is no messy, Windows system structure definition, and there will be no sleepy vulgarity when reading! In the book, some are lively and vivid words; some are exaggerated and pure campus life; some are unforgettable experiences; Roaming in a beautiful world; some tips and suggestions can lead readers to a strong hobby, and they can consciously go down and find relevant information to improve themselves. Common sense is like a circle; the area of ??the circle is a tool you know; the side length of a circle is a tool you don't know. The larger the circle, the longer the side. So the more you know, the more you don't know! Therefore, we must study consciously and study diligently, so as not to fall behind and to compete with today's complex society! Buffer overflow is the most common problem on security forums, including the use of stack buffer thinking, the beginning of writing, deformation, high-level use of ShellCode, and the use of heap overflow, personal analysis of vulnerabilities, etc. Of course, there are plenty of examples for each section, so let's practice and apply what we've learned. The next chapter is based on one chapter, and gradually deepens and opens. When studying the previous content, if you don't understand some parts, you can find the answer in the following chapters; if you don't understand the previous content, you can also read the previous common sense to further stabilize yourself! If the reader can spare 5 minutes to read this book, then I hope to induce you to spend a few more hours reading this book. Then use more time to practice every example in the book, further study, and further search for answers. The "After-Class Answering Questions" part is based on the problems encountered in the author's study and the more common questions on the forum. Part of it may be the precautions that can't be found by rummaging through the information. Ultimately, I hope reading this book didn't waste your precious moments!)
