This is MUCH bigger deal than most understand. This will cost less than $10 to build and their is no hardware solution on phones or Alexia. Phreaking is back.

This has nothing to do with phreaking. Phreaking is about hacking the phone network, not covert use of the built-in features of a network-enabled device.

Yeah, those parts are easily available on Aliexpress in droves. Imagine this in the crowded subway. "hey siri" "show me pictures of CENSORED " "send the first picture to mom" "yes, send it" :S

I’m pretty sure that Hey Siri is keyed to the users voice to some extent, so Siri should be safe. Not sure about Google, Cortana, Alexa etc.

Cortana has that as an option in Settings, but it's not on by default.

You know, I'm ok with a physical button press as the authentication method.

Preferably some kind of hardware on-off switch for the physical microphone.

And camera
