Software Reverse Engineering: Navigating x86 Windows Applications with Ghidra

Software Reverse Engineering: Navigating x86 Windows Applications with Ghidra Unlock the secrets of x86 Windows applications with this hands-on guide to software reverse engineering using Ghidra, the industry-leading reverse engineering tool. Through a series of practical examples and in-depth explanations, you'll gain a deep understanding of how to deconstruct and analyze 32-bit Windows applications written in C and C++. Mastering Assembly Code and Decompilation Patterns Starting with the basics of decompilation and interpretation of simple functions, you'll progress to more advanced topics such as loops, C-style strings, floating-point numbers, and the corresponding assembly instructions and decompiled code patterns in Ghidra. You'll learn how to: Use Ghidra's decompiler and other essential tools for reverse engineering Windows applications. Analyze 32-bit x86 & x87 assembly code, decompile it with Ghidra, and re-engineer the functionality when needed. Understand and interpret C and C++ constructs in assembly and in the decompiled C-like pseudo-code in Ghidra. Work with floating-point numbers using the x87 assembly instruction set, as well as peek into SIMD programming. Reverse engineer C++ classes with and without virtual methods, handle inheritance, including multiple inheritance, and deal with operator overloading. Practical Application: Creating a DLL Wrapper Take your skills to the next level with a step-by-step guide to creating a dynamically linked library (DLL) wrapper in C and C++ to intercept and modify the behavior of an example application in the runtime. You'll learn how to: Create a DLL wrapper to proxy valid function calls to the original DLL. Use the wrapper to modify the program behavior and data to unlock the example program secrets.
