Alright guys, I finally cracked the VMProtect 3.x virtualization layer.
I'll share the full method step‑by‑step: OEP finding, IAT rebuild, and the anti‑debug bypass.
Prerequisites: x64dbg + ScyllaHide + a decent understanding of x86 assembly.
Let's start with the entry point detection. I used a custom script that hooks VirtualProtect...
