Step 1. Start KSDumper and Dump the Challenge from Memory by running it. Download Here - https://github.com/EquiFox/KsDumper from GitHub. You can also use any Kernel base Dumper or JIT Dumper https://github.com/Anonym0ose/JitDumper
(When You use KSDumper, You may have to Load Unsafe Driver which you can do by running them using Command Prompt if only You are getting Access Denied error by running normally)

Step 2. Fix Sections Header of your Dumped File using CFF Explorer. Download from - https://ntcore.com/?tag=cff-explorer here and Fix the Broken value and Untick the IL only check in .NET section.

Step 3. Now Clean the Mutations of VMProtect using Demutation Tool made by wwh1004. You can read here - https://github.com/wwh1004/blog/tree/master/[.NET]反混淆VMP.NET之Mutation
(You can also download the Compiled file from this Link - https://disk.yandex.com/d/Zq2q-6YnkrDWiQ )

Step 4. Clean the File using de4dot. Use the Official de4dot without any mod. You can Download from Here - https://github.com/de4dot/de4dot
(Use --keep-names ntpfg while cleaning the file using de4dot)

Step 5. Use VMP Killer by DarkBullNull. Download Here - https://github.com/DarkBullNull/VMP.NET-Kill/releases/download/2.1/Release.rar
(Use Option 2 First and Fix CRC and Debug Check and after this use Option 4 to uncover the Hide Call Method)

Hell0 Mr @BlackHat,

I know this topic is old, but can you provide any logic on the CFF Sections Headers Fixing?

VMP has changed them and I belive that might have disabled Dem.

Anyway, thanks for the info!

I too agree that where the section header of vmp has been changed, Demutation is not working there.  @BlackHat  can you please suggest how to deal with it?
