To reverse engineer VMProtect-protected software, follow these steps: decides which handler to jump to

For example, a simple MOV EAX, 1 became:

He stared at the assembly. VM_Handler_0x01 , VM_Handler_0x02 ... He mapped the handlers manually. "It's modular arithmetic," he realized. "It's a Scalar Multiplication on a curve."
