The Shellcoder's Handbook: A Guide to Finding and Exploiting Security Holes
The Shellcoder's Handbook is a book written by a group of top security experts in the world, featuring 40 percent new content on how to find security holes in any operating system or application. The book covers topics such as stack overflows, heap overflows, format string bugs, shellcode, protection mechanisms, database software, kernel overflows, and more. The book also includes examples and code snippets for various platforms, such as Windows, Linux, Solaris, OS X, and Cisco IOS.
If you are interested in learning how to discover and exploit security vulnerabilities in software systems, this book is for you. You will learn how to analyze binary code, write your own exploits, bypass security defenses, and hack the Windows and Unix kernels. You will also learn how to use tools such as debuggers, disassemblers, fuzzers, and fault injectors to aid your hacking efforts.
The Shellcoder's Handbook is available in both print and digital formats. You can buy the eBook for $30.00 from Google Books[^1^] or download a free PDF version from the Internet Archive[^2^]. You can also find more information about the book on its official website[^3^]. Whether you are a beginner or an expert in security hacking, this book will teach you everything you need to know about the art of shellcoding.Chapter 1: Introduction to Exploitation
In this chapter, you will learn the basics of exploitation, which is the process of taking advantage of a security vulnerability in a software system to execute arbitrary code or commands. You will learn about the different types of vulnerabilities, such as buffer overflows, format string bugs, and heap overflows. You will also learn about the different types of exploits, such as local and remote exploits, shellcode and return-oriented programming (ROP), and privilege escalation and persistence.
The chapter will introduce you to some common tools and techniques that are used by hackers to find and exploit vulnerabilities, such as reverse engineering, debugging, disassembling, patching, and injecting. You will also learn how to use some popular tools such as gdb, objdump, strace, and Metasploit. You will also learn how to write your own simple exploits using C or Python.
By the end of this chapter, you will have a solid foundation of the concepts and skills that are required for successful exploitation. You will be able to identify and exploit some common vulnerabilities in Linux and Windows systems. You will also be able to write your own shellcode and ROP chains to execute arbitrary code or commands on a target system.Chapter 2: Stack Overflows
In this chapter, you will learn about one of the most common and classic types of vulnerabilities: stack overflows. A stack overflow occurs when a program writes more data to a memory region than it can hold, causing the data to overwrite adjacent memory regions. This can lead to corruption of important data, such as function return addresses, local variables, and saved registers. By carefully crafting the data that overwrites the stack, an attacker can gain control of the program's execution flow and execute arbitrary code or commands.
The chapter will explain how the stack works in both Linux and Windows systems, and how to exploit stack overflows on both platforms. You will learn how to use tools such as gdb and objdump to analyze binary code and find stack overflow vulnerabilities. You will also learn how to write your own exploits using C or Python, and how to bypass some common protection mechanisms such as stack canaries, non-executable stacks, and address space layout randomization (ASLR).
By the end of this chapter, you will have a thorough understanding of the theory and practice of stack overflow exploitation. You will be able to exploit some real-world programs that are vulnerable to stack overflows, such as wu-ftpd and sudo. You will also be able to write your own shellcode and ROP chains to execute arbitrary code or commands on a target system. aa16f39245
