How to unpack VMProtect 3.x

P
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...

Dope! I've been struggling with the mutation engine.
Do you use a custom script for the OEP scan or just manual tracing?
Also, any tips on handling the hardware breakpoint detection? I keep getting hit by the anti-debug.

I wrote a small Python script that automates the unpacking flow – it hooks the VirtualProtect calls and dumps the unpacked sections.
I'll attach it here once p27a finishes the write‑up.
This is pure gold. Been waiting for a proper VMProtect 3.x walkthrough for months.

For the hardware breakpoints – I found that using the DRx registers directly with a kernel driver works best.
But that's overkill for most people. The ScyllaHide stealth mode usually does the job.

Thanks for sharing this p27a. I've been reversing a sample that uses VMProtect 3.8 – the method seems similar.
Quick question: did you have to deal with any anti-tamper checks during the IAT rebuild?
