We also took advantage of being allowed to change an intent’s functionality after the application had already passed the platform’s review process.Ĭ. To eavesdrop on Alexa users, we further exploit the built-in stop intent which reacts to the user saying “stop”. We leverage the “fallback intent”, which is what a voice app defaults to when it cannot assign the user’s most recent spoken command to any other intent and should offer help. The ‘Smart Spies’ hacks combine three building blocks:Ī. Eavesdrop on users after they believe the smart speaker has stopped listening.Request and collect personal data including user passwords.Through the standard development interfaces, SRLabs researchers were able to compromise the data privacy of users in two ways: Security best practice deviations allow abuse of smart speaker development functionality The input slots are converted to text and sent to the application backend, which are often operated outside the control of Amazon or Google. (“Tell me my horoscope for today.”) These set phrases can include variable arguments given by the user as slot values. (“Alexa, turn on My Horoscopes.”) Users can then call functions ( Intents) within the application by speaking specific phrases. Amazon and Google allow third-party developers access to user inputsīoth Alexa Skills and Google Home Actions are activated by the user calling out the invocation name chosen by the application developer.
We created voice applications to demonstrate both hacks on both device platforms, turning the assistants into ‘Smart Spies’.
The flaws allow a hacker to phish for sensitive information and eavesdrop on users. SRLabs research found two possible hacking scenarios that apply to both Amazon Alexa and Google Home. The apps currently create privacy issues: They can be abused to listen in on users or vish (voice-phish) their passwords.Īs the functionality of smart speakers grows so too does the attack surface for hackers to exploit them. These smart speaker voice apps are called Skills for Alexa and Actions on Google Home. The capability of the speakers can be extended by third-party developers through small apps. Smart speakers from Amazon and Google offer simple access to information through voice commands.
Google voice actions listen to how to#
I had it set so that when the display turn on and your finger is over the proximity sensor it would launch it, but I didn't know how to turn it off, so every time anything got in front of the sensor while the screen was on, it would launch it.UPDATE December 17, 2019: Attacks still possible Six weeks after first publicly discussing the Smart Spies attacks, we performed some retests to see whether Google and Amazon implemented sufficient checks to mitigate the attacks. VoiceSearchActivityĪs soon as the Phone is unlocked, while your finger is over the sensor button, it launches Voice Search and is ready to listen to a command. Secure Settings: Launch Activity - Google Search. So far this is the best I can do with Tasker: State: Display Unlock & Proximity Sensor I have looked everywhere, searched for apps and have been re-searching ways to make this work on Tasker but no luck. Press Power>Swipe Up for Google Now>Press Microphone button>Speak If I can shave a few seconds from opening the app I would be very happy. I am heavily using this voice actions lately to send texts, navigate and finally we can post to G+/Twitter.
Maybe like holding the power button for 2 seconds while the screen is off immediately starts listening for a command? I remember Cyanogenmod having this feature, but it was only to launch the Torch app.
