Wired: “Hackers pueden controlar Siri desde
Last year iOS 8 introduced “Hey Siri”, a voice command that allows us to invoke the personal assistant of the block without touching a single button even with the iPhone locked. The system worked well, although it required the phone to be connected to the charger and lent itself to the jokes of friends and co-workers by responding to everyone without distinction.
With the launch of the iPhone 6s and the iPhone 6s Plus, “Oye Siri” is always active , even without a charger, so the scenarios in which a stranger could interact with our phone multiplied. Fortunately, iOS 9 remedies this before it becomes a problem with a feature that, in the absence of an official name, many have named Voice ID .
Now, when we start our new iPhone for the first time or activate the “Oye Siri” function in Settings> General> Siri> Allow Oye Siri we must follow a quick five-step setup process with which we train the assistant to only recognize our voice. It’s very simple, just repeat “Oye Siri” three times, followed by two longer sentences “Oye Siri, what’s the weather like today” and “Oye Siri, it’s me”.
Five sentences, that’s all Siri needs to differentiate our voice from the rest, considerably improving its performance especially in noisy environments, and leaving the jokes between us. Officially Voice ID is not a security measure but rather a refinement to prevent all iPhones 6s in a cafe from jumping out at the first sign that someone wants to ask something to their own phone, but still, it definitely fulfills this other role as well.
After inviting at least ten people to try to wake up my iPhone 6s Plus by saying “Hey Siri”, none of them succeeded, just the recorded voice.

If you are concerned about security to the point of covering your webcam with a post-it , disable “Hey Siri”. Everyone else, congratulations. Siri works better than ever , and now even from across the room with her hands full of flour.
I think I can live with the possibility that someone from ANSSI, the French IT security agency, will try to ask Siri the weather using a “discreet antenna” five meters away and only if I have my helmets on. Of course, having my phone talk to me on the spur of the moment will not arouse any suspicions.
