VMProtect is a code protection tool that uses a combination of encryption, compression, and virtualization to protect executable files. When a software developer uses VMProtect to protect their application, the tool encrypts the code and embeds a virtual machine (VM) into the executable. The VM executes the encrypted code, making it difficult for attackers to analyze the program's behavior.
