Today Xiaobian to share with you about the Revit plug-in shell search and shell-breaking methods of the relevant knowledge, detailed content, clear logic, I believe that most people are too aware of this knowledge, so share this article for your reference, I hope you have something to gain after reading this article, let's take a look at it.

Use of the shell search tool:

This is a free shell search software, compared with the familiar PEID 0.95, this shell search software has more accurate functions than other software, and has a Chinese version, so it is more convenient to use, so this software is highly recommended. (for those who don't know what a shell is, you can learn more about it by adding a shell to Baidu.)

(1) when you use it for the first time, you can set the font in the setting and reopen it before it takes effect. By default, just set the √ section on it.

(2) drag the shell directly to the page of the software to see the shell information.

(3) example: this is an unshelled dll file

You can see that this is an unshelled dll file that can be decompiled with a decompiler.

This is a shell using the .NET open source obfuscator ConfuserEX. Basically, this obfuscator is used for encryption on the market, and there are most tutorials on cracking this shell on the Internet.

This is the most widely used plug-in on the market, using PV Logiciels-dotNet Protector technology, this technology is Chongqing Huidu technology, there are few resources available for this shell.

The use of shell breaking tools

Open the folder where De4Dot is located, hold down Shift, right-click the folder → and choose "Open Command window here"

Enter de4dot + the path of the dll file to crack

After completion, the corresponding file will be generated under the original dll file.

If the crack is successful, you can directly use the decompiler software to compile. Obviously, the shell is not successfully broken in the image above.

Therefore, it cannot be decompiled.

Use UnconfuserEx to crack

This is very easy to use, just load the dll file directly, and if successful, it will be compressed into an exe file.

If it fails, it will prompt a fatal error.

After using UnconfuserEx, we try to decompile:

The shell is successfully broken and all the source code is visible.

Therefore, the commonly used ConfuserEX obfuscator is not foolproof and needs multi-layer protection.

These are all the contents of this article entitled "how to search and break shells in Revit plug-ins". Thank you for reading! I believe you will gain a lot after reading this article.
