Why Reverse Engineer?
Reverse engineering allows you to learn about a program’s structure and its logic. Reverse engineering thus leads to critical insights regarding how a program functions. This kind of insight is extremely useful when you exploit software. There are obvious advantages to be had from reverse engineering. For example, you can learn the kind of system functions a target program is using. You can learn the files the target program accesses. You can learn the protocols the target software uses and how it communicates with other parts of the target network. The most powerful advantage to reversing is that you can change a program’s structure and thus directly affect its logical flow. Technically this activity is called patching, because it involves placing new code patches (in a seamless manner) over the original code, much like a patch stitched on a blanket. Patching allows you to add commands or change the way particular function calls work. This enables you to add secret features, remove or
