    Hackers Can Silently Control Siri

    Hackers Can Silently Control Siri From 16 Feet Away

    Siri may be your personal assistant. But your voice is not the only one she listens to. As a group of French researchers have discovered, Siri also helpfully obeys the orders of any hacker who talks to her—even, in some cases, one who's silently transmitting those commands via radio from as far as 16 feet away.

    A pair of researchers at ANSSI, a French government agency devoted to information security, have shown that they can use radio waves to silently trigger voice commands on any Android phone or iPhone that has Google Now or Siri enabled, if it also has a pair of headphones with a microphone plugged into its jack. Their clever hack uses those headphones' cord as an antenna, exploiting its wire to convert surreptitious electromagnetic waves into electrical signals that appear to the phone's operating system to be audio coming from the user's microphone. Without speaking a word, a hacker could use that radio attack to tell Siri or Google Now to make calls and send texts, dial the hacker's number to turn the phone into an eavesdropping device, send the phone's browser to a malware site, or send spam and phishing messages via email, Facebook, or Twitter."The possibility of inducing parasitic signals on the audio front-end of voice-command-capable devices could raise critical security impacts," the two French researchers, José Lopes Esteves and Chaouki Kasmi, write in a paper published by the IEEE. Or as Vincent Strubel, the director of their research group at ANSSI puts it more simply, "The sky is the limit here. Everything you can do through the voice interface you can do remotely and discreetly through electromagnetic waves."

    The researchers' work, which was first presented at the Hack in Paris conference over the summer but received little notice outside of a few French websites, uses a relatively simple collection of equipment: It generates its electromagnetic waves with a laptop running the open-source software GNU Radio, a USRP software-defined radio, an amplifier, and an antenna. In its smallest form, which the researchers say could fit inside a backpack, their setup has a range of around six and a half feet. In a more powerful form that requires larger batteries and could only practically fit inside a car or van, the researchers say they could extend the attack's range to more than 16 feet.

    Here's a video showing the attack in action: In the demo, the researchers commandeer Google Now via radio on an Android smartphone and force the phone's browser to visit the ANSSI website. (That experiment was performed inside a radio-wave-blocking Faraday cage, the researchers say, to abide by French regulations that forbid broadcasting certain electromagnetic frequencies. But Kasmi and Esteves say that the Faraday cage wasn't necessary for the attack to work.)

    Thanks for posting this, A.J.

    Hubby gave me an iPhone a couple of years ago, but I never felt comfortable using the "Siri" feature - Something about it kinda creeped me out.

    Apparently, you can shut SIRI off. Someone posted this for me when I asked...

    Open the Settings app in iOS and go to “General” Tap on “Siri” and near the top of the screen, toggle the switch next to “Siri” to the OFF position. Confirm that you wish to disable Siri completely by tapping on “Turn Off Siri” Exit out of Settings as usual.
    Here's a site with pictures!

    Tell me it ain't so..my dear friend Siri is fickle?!!! I love Siri..use it a lot

    Man!

    So if I read this right the hacking can only take place if you have Siri turned on and are using headphones?

    That's the way I read it too, but it's the earbuds/phones that have a mic in them as well. I rarely use earbuds.

    I don't think it's an issue unless your earbuds have a mic on the cord.

    Someone more savvy can correct me if I'm wrong.

    yeah.. they do. I talk to my bosses all the time.. and my sister and daughter too.. sometimes my grandaughter AND I do "remind me" ALL the time.

    I'll just upgrade to the 6s sooner than I'd expected.
