For the next 24 Houhs, google’s letting you skip the line for project Fi

Google’s all excited about the official launch of its flagship Nexus devices. We’ve reviewed the 5X and 6P and since they’re both unlocked, you get to choose your carrier.

One option? Project Fi. It’s been closed off to the world up until now, but the team is opening the gates just for the rest of the day:

The lure of Project Fi is that it intelligently connects you to the best network…be it a 4G partner or freely available Wi-Fi. I’ve been using it with the Nexus 6P and so far, so good. I even was able to get access while driving to a mountainy part of northern California this weekend.

AT&T : Connect all your devices with one number

As you buy more devices and wearables, the idea of having one phone number to connect them all is an increasingly attractive one.

AT&T is readying a service that will allow users to connect all their devices, from smartphones to wearables, with a single phone number.

The company promises that the service, called NumberSync, will allow users to send and receive texts and calls from any device using one number. A person familiar with the matter confirmed to Mashable that the service will be made possible due to changes on AT&T's existing telecom network. And unlike some similar Bluetooth-based solutions, NumberSync connectivity will function even if the user's primary mobile device with the originating number is physically nowhere near the other NumberSync-connected devices.

"Since NumberSync operates in our wireless network, it is not dependent on a Bluetooth connection to your smartphone," AT&T spokesperson David Christopher posted on the company's website on Wednesday. "Your devices don’t need to be near each other and NumberSync will work even if your primary phone is turned off or disconnected from the network.

Christopher also mentions that the service will be able to connect wearables like fitness bands and hints at possible in-car functionality. Yet no specific NumberSync devices are mentioned, and it's not clear whether the service will work across a wide array of mobile platforms such as iOS, Android and Windows Phone.

Apple offers a similar concept in the form of its Continuity feature, which allows you to make and receive calls through your Mac and iPad via your iPhone. But depending on how AT&T's service is delivered, NumberSync has the potential be much more powerful than Apple's solution.

AT&T says the first NumberSync-ready device (likely a wearable) will launch sometime this month, with at least two additional devices to come during the holiday season.

Hackers figure out how to activate Siri without talking

These hackers aren't ventriloquists, but they might have figured out something even cooler.

Researchers at the ANSSI, a French governmental agency that conducts cybersecurity research, have figured out a way to remotely and silently access mobile concierge services like Siri and Google Now, reports Wired. With microphone-equipped headphones plugged into a phone, the hackers can send radio frequency signals to sound like a person activating Siri or Google Now.

There's really nothing to worry about here if you have a phone with Siri or Google Now enabled from the lock screen; the likelihood that some malicious hacker could pull of this attack without you knowing is fairly slim.

The hackers use a laptop running a software-defined radio, an amplifier and an antenna to broadcast radio wave signals that are picked up by the cord on the headphones. The phone interprets these electrical signals as someone speaking into a microphone, giving the hackers full access to Siri functions.

Using a simplified, portable setup, the hackers can transmit phone-interpretable signals at a range of six and a half feet, with a larger setup increasing range to 16 feet. The hackers claim the smaller setup can fit and function in a backpack.

As reported by Wired the hackers describe a scenario in which this was used in a congested area to trick a number of phones into calling a paid hotline. The only other scenario we can think of would be if someone working in a public area left their phone with headphones plugged in out while stepping away from their desk. The hackers could then theoretically set up their spoofing device, but it would be much easier just to grab the person's phone and start messing with it.

The other limiting factor is that many new phones only activate concierge services when the phone's owner is talking, though a long press on the headphone's remote button will also do the same. With my iPhone 6S, Siri only turns on when I say "hey, Siri," but my desk neighbor could just as easily grab my phone and press the button to start sending texts and making calls.

While this attack isn't much of a threat to iPhone or Android owners, the method in which it was carried out is fascinating. It also serves as a reminder that lock-screen active concierge isn't all that secure; whether or not they know it, smartphone users are trading some level of security for convenience.

The researchers suggest that headphone manufactures add an extra layer of shielding to their cords, but considering the huge swath of headphone makers in the industry, this seems unlikely to ever happen.

So, not ventriloquism, but definitely cooler.
