NUANCE: Near Ultrasound Attack On Networked Communication Environments. (arXiv:2305.10358v1 [cs.CR])

This study investigates a primary inaudible attack vector on Amazon Alexa
voice services using near ultrasound trojans and focuses on characterizing the
attack surface and examining the practical implications of issuing inaudible
voice commands. The research maps each attack vector to a tactic or technique
from the MITRE ATT&CK matrix, covering enterprise, mobile, and Industrial
Control System (ICS) frameworks. The experiment involved generating and
surveying fifty near-ultrasonic audios to assess the attacks' effectiveness,
with unprocessed commands having a 100% success …
