How to Use Crack Tools to Reverse Engineer Software
If you are interested in reverse engineering, you might want to use some crack tools to help you analyze and modify software. Crack tools are software that can remove copy protection from a software or enable breaking into a computer network or a software application[^2^]. In this article, we will introduce three popular crack tools: Hiew, SoftIce, and W32Dasm.
Hiew stands for Hacker's View. It is a hex editor that can view and edit files of any length in text, hex, and decode modes. It can also modify the code of running processes. Hiew is useful for patching, cracking, and analyzing malware. You can download Hiew from its official website: https://hiew.ru/
SoftIce is a kernel mode debugger that can debug multiple applications simultaneously. It can also monitor and manipulate the hardware and software interrupts. SoftIce is powerful for debugging drivers, rootkits, and protected mode applications. You can download SoftIce from its official website: https://www.nu-mega.com/softice/
W32DASM is a disassembler that can translate machine language back into assembly language[^3^]. It can also display the imported and exported functions of an executable file. W32DASM is ideal for reverse engineering, as it can help you understand how a program works and how to modify it. You can download W32DASM from its official website: https://www.softpedia.com/get/Programming/Debuggers-Decompilers-Dissasemblers/WDASM.shtml
In this article, we have introduced three crack tools that can help you with reverse engineering software: Hiew, SoftIce, and W32Dasm. These tools are powerful and versatile, but they also require some knowledge and skills to use them properly. If you want to learn more about reverse engineering, you can check out some online courses or books on the topic.
How to Use SoftIce to Debug a Program
In this section, we will show you how to use SoftIce to debug a program that has a hidden feature. We will use a simple example program called Hidden.exe that displays a message box saying \"Hello World\" when you press a button. You can download it from here: https://example.com/hidden.exe
The first step is to install and run SoftIce. You can do this by following the instructions on its official website: https://www.nu-mega.com/softice/. You will see a blue screen with some information and commands. This is the SoftIce interface.
The next step is to load Hidden.exe in SoftIce. You can do this by using the File menu and selecting Load Module. Enter the path of Hidden.exe and press Enter. You will see something like this:
This shows some information about the module, such as its name, path, size, base address, and entry point. The entry point is the address where the program starts executing.
The next step is to set a breakpoint at the entry point. A breakpoint is a point in the code where the execution stops and SoftIce takes control. You can set a breakpoint by using the Breakpoint menu and selecting Set Breakpoint. Enter the address of the entry point (00401000) and press Enter. You will see something like this:
Breakpoint 0 at 00401000
This shows that you have set a breakpoint at address 00401000.
The next step is to run Hidden.exe outside of SoftIce. You can do this by minimizing SoftIce by pressing Ctrl+D, or by using the Window menu and selecting Minimize. Then you can run Hidden.exe normally by double-clicking on it or by using the Run menu and selecting Run Module.
As soon as you run Hidden.exe, SoftIce will pop up and show you the code at the breakpoint. You will see something like this:
This is the assembly code of Hidden.exe at the entry point. You can see that it simply displays a message box saying \"Hello World\" and then returns.
The next step is to find the hidden feature of Hidden.exe. You can do this by using the Search menu and selecting Find String. Enter \"hidden\" as the search term and press Enter. You will find something like this:
00402000: 68 69 64 64 65 6E 00 hidden.
This shows that there is a string \"hidden\" at address . This might be related to the hidden feature. 29c81ba772
