What is VMProtect?

Normally, when you write a program, it can easily be reverse-engineered using a debugger. When the reverser opens your program with a debugger and looks inside, they can easily understand what you're doing on which line and where you're checking the password.

VMProtect takes your code, breaks it into separate parts, and converts these into Virtual Machine language; this process is called Virtualization, which we've all heard of at least once. The key features of VMProtect are Virtualization and Mutation.

VMProtect has three current versions:

Lite - Professional - Ultimate

Lite: Having a house but no door. [Anyone can enter your house]

Professional: Having a house and the door opening only with your key. [Someone who has the key can enter your house]

Ultimate: Having a house and the door opening with your biometric data. [No one can enter your home except you]

Depending on VMP versions, Virtualization and Mutation levels vary.

Ultra = Virtualization + Mutation 

What is Virtualization (Virtualization)?

It takes your source code and transforms it into a completely different structure—a bytecode format that only a special "key" (the VMP) can understand. This key acts like an imaginary processor embedded within the program and equipped with its own unique instructions.

The virtualization phenomenon is as follows: Once the code is virtualized, the resulting virtual structure is both incredibly robust and nearly impossible to revert [Devirtualization].short: A virtualized code segment does not transform into the processor's native "machine language" instructions even at runtime. This makes it impossible for a reverser to obtain your original code by monitoring the program's execution or tampering with the file. The code now lives only inside that "imaginary machine" and is a completely closed box for someone looking from the outside.

What is a Mutation (Mutation)?

Mutation is actually a very simple but highly effective method. Mutation involves running a single line of code you wrote through thousands of different and complex paths without changing its function at all.

Example: Let's say the only function of an unmodified (unprotected) .exe is to go from home to school.

With mutation, this process remains unchanged but becomes incredibly complex and

wake up at home, wash your face, wash your hands, eat breakfast, then you go out, take 10 laps around the block, walk those same roads twice on your way to school, and finally arrive at school.

As a result, you arrived at school again (meaning the code worked), but a reverser watching you from outside would be left baffled until they figure out whether your real goal was to go to school or just take a stroll around the neighborhood. These junk operations scattered among the code are the ideal way to hide the truly important logic.

How to Use VMProtect?

That question that comes to everyone's mind when using VMProtect: "Which version should I choose?" I've listed the top 3 versions on the forum below:

VMProtect Ultimate 3.9.4

VMProtect Lite 3.10.4

VMProtect Professional 3.9.6

My personal preference is VMProtect Ultimate 3.9.4; you can use it as you wish.

You need the Lib and Include folders in your VMProtect folder. You need the VMProtectSDK.h file from the Include folder and the VMProtectSDK64.lib file from the Lib folder. You can choose according to your project structure (x86 - x64).

After including these files in your project, you must include them at the very beginning of your code (#include "VMProtectSDK.h").

I demonstrated this on a simple login checkcheck project.

VMProtect SDK functions and what they do:

VMProtectBeginVirtualization("name"): Protects the code within the block in the most secure and robust mode: "Virtualization".

VMProtectBeginMutation("name"): Protects the code between brackets in "Mutation" mode (fast but complex).

VMProtectBeginUltra("name"): Provides the highest level of protection by using both Virtualization and Mutation features simultaneously.

VMProtectEnd(): Determines the end point of the initiated protection block; VMP does not interfere beyond this point.

VMProtectIsProtected(): Checks whether the program is currently protected by VMP.

VMProtectIsDebuggerPresent(check_kernel): Checks whether the program has been monitored with a debugger.

VMProtectIsVirtualMachinePresent(): Determines whether the program is running on a physical computer or in a virtual machine.

VMProtectIsValidImageCRC(): Checks whether the file has been tampered with.

VMProtectDecryptStringA / W: Encrypts the messages (strings) you type so that they do not appear clearly in memory.

After using VMProtect commands in our project, we can edit and compile it through VMProtect.

Let's start VMProtect

In the incoming UI, let's open the .exe file via Open or by drag and drop.

Right-click on the "Functions for Protection" section, select "Add Function," and choose the functions you have protected in your project (those you wrote between Begin/End) from the list.

After selecting the function, determine the protection type from the Compilation Type section on the right side:

Mutation: Changes the form of the code.

Virtualization: Embeds the code into a virtual machine.

Ultra: Mutation + Virtualization is the most robust.

After completing these operations, left-click on the Options section and configure the following settings according to your preferences.

Version: You select the version of the virtual machine. If you choose "Compact", the size will be reduced, but you will sacrifice some security.

Instances: You select how many copies of the virtual machine there will be (default is 10). Each copy will have different characteristics, thus confusing the reverser even more.

Complexity: Determines how complex the commands within the virtual machine will be. Increasing it increases the file size but turns into a complete nightmare for the reverser.

Memory Protection: Protects the program's copy in RAM. If someone tries to modify your file in memory, the program detects this and shuts down.

Import Protection: Hides the list of Windows APIs used by the program from the reverser. It is my personal recommendation to use it together with "Pack the Output File".

Resource Protection: All the resources of the program except the icon and manifest (images, files, etc.) Packages the output file.

Pack the Output File: Packages the file to reduce its size. When the program runs, everything runs through RAM and leaves no trace on the disk. Important: If you open this, make sure that the "EntryPoint" part is also protected (Virtualized) so that they cannot manually unpack.

Segments: Allows you to change the name of the .vmp-named sections that VMP adds. By making this .UPX or a random name, you can hide that VMP is being used.

Strip Debug Information: Deletes the debug information in the code. If you are using .NET, it makes things difficult by automatically changing the names (class/method).

Strip Relocations: Deletes unnecessary relocation tables that take up space and allows VMP to use that space for its own operations.

Watermark: Adds a custom stamp to the file to prove ownership.

Debugger: Prevents the program from being debugged with tools like OllyDBG or WinDBG. If detected, it throws an error and closes.

Virtualization Tools: Prevents the program from running in virtual machines like VMware or VirtualBox.[User+Kernel] is my recommendation.

Messages: Here, you can localize the famous error messages that appear to the user when the debugger or virtual machine is caught, according to your preferences.
