Peeling the Onion: A Practical Guide to VMProtect Reverse Engineering

VMProtect is one of the most notorious protectors in the software industry. Unlike simple packers (UPX) or obfuscators, it doesn’t just compress or rename symbols – it transforms original x86 code into a custom bytecode language executed by a virtual machine embedded in the protected binary.

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. vmprotect reverse engineering

He ran Seraphim. The driver logged every instruction executed by the virtual CPU. The logs were massive—gigabytes of text. Peeling the Onion: A Practical Guide to VMProtect

He switched tactics. Instead of reading the bytecode, he had to reverse the interpreter. He began classifying the Handlers. Base of bytecode

Write a script to:

• Base of bytecode.
• Size of bytecode.
• Number of virtual registers.
• Handler table base.
