The Amazon Echo is vulnerable to a physical attack that allows an attacker to gain a root shell on the underlying Linux operating system and install malware without leaving physical evidence of tampering. Such malware could grant an attacker persistent remote access to the device, steal customer authentication tokens, and the ability to stream live microphone audio to remote services without altering the functionality of the device.
very interesting. It would be nice to replicate this in our group as an insecurity demonstration. I’m gonna add that to the ideas box.
