AVRop VM: A ROP based M/o/Vfuscator VM on a Harvard device

A novel virtual machine (VM) based on Return-Oriented Programming (ROP) was developed for an AVR microcontroller. The VM adapts the Movfuscator concept to a Harvard architecture device, implementing a single ROP chain that can execute different payloads through memory-mapped instruction interpretation. The approach allows for executing varied functionality using the same ROP chain on an embedded device with limited resources.
