Alexa, are you listening?

A physical attack on early Amazon Echo models allows root access by exploiting exposed debug pads and an SD card boot configuration. By gaining root shell access, an attacker can install a malware implant that turns the device into a remote wiretap. The attack requires physical access to the device and can potentially stream live microphone audio to remote services without disrupting the Echo's normal functionality.

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.
