Hackers Can Use Smart Watch Movements To Reveal A Wearer's ATM PIN (ieee.org)

the_newsbeagle writes: By gaining access to the sensors in someone's smart watch, hackers could track the person's hand movements at an ATM and figure out his/her pin. The hacker needn't be anywhere near the ATM; data can be lifted from the smart watch by either a discreet wireless sniffer or by malware on the watch that sends info to a server. This is hardly the first demonstration of the security flaws in smart watches. Last year, a research group showed that a watch's sensors can reveal keystrokes on a computer keyboard. The team of researchers, led by Chen Wang and Yingying Chen at the Stevens Institute of Technology in Hoboken, New Jersey, were able to record movements down to the millimeter and crack private ATM PINs with 80 percent accuracy on the first try. To eliminate the security breach, manufacturers could better secure the data stored in their wearables, and/or add noise so one's physical hand movements cannot be as easily translated. Of course, consumers could simply wear their smart watch on their non-dominant hand.

      On a personal note, I'm not worried. I figured out how to type my pin without any visible movement of my hand (the unavoidable movements being covered by my other hand). This was because there were a number of cases of people installing cameras near ATMs to steal PINs. I just checked, and my non-smart watch doesn't move more than a milimetre in any direction. If I upgrade to a smart watch, they're still not getting anything.

      I normally just use multiple fingers instead of just the single index finger to enter the PIN. That'll make it much harder (though maybe impossible) to decipher the movements of my hand to derive the PIN.

  13. Scramble the keypad by Archfeld · · Score: 1

    We could always just present the numbers on a keypad in a random position for each transaction. That of course would require conscious thought and effort of the person using the keypad which is probably too much to ask the 'average' user. It would also make life more difficult for blind users.

      When I was in college (in the early 90s!!!) the keypad to get through the door to the computing labs out-of-hours would scramble like this. It always looked cool and was a good idea, but also a bad idea for the very reason you mentioned - several of the students were blind and then couldn't get through the door. Then ended up turning off the scrambling.

      I was back there a couple of years ago, and the same keypad was still in place (and the same codes still worked - great security!). And it still didn't scramble.

      If you add braille to the keys too (the relevant bumps could present themselves), then it would work for blind people. But I'm sure there will be others that will run into issues... maybe put a button to the side or a selection on the screen to set them in the normal order, but default them to scramble...

      You could combine the idea with those new touchscreens that can change texture and create bumps at will, moving the braille along with the numbers.

    Excuse me sir. Can I trouble you to type these numbers into this keypad. There's quite a few combinations and I need you to do each 3 times. Why? Oh just calibrating accelleratometer in your smartwatch so I can identify all future numbers you type.

  16. ATM's are unsafe anyway by zmooc · · Score: 4, Interesting

    Even without this technology, your fingers will leave a heat mark on the ATM keys long enough for a malicious person to take a picture of it with a thermal camera. Therefore, when I use an ATM machine, I always hold my fingers over a subset of keys to warm them up while waiting for the excruciatingly slow computer in the thing to do its job. That probably sufficiently masks the thermal print left by actually entering my PIN. Furthermore, I have developed a habit of pressing on the keypad frame as if pressing a key on the pad to fool lurkers. That would probably also protect against the smartwatch appraoch. It's rather easy to protect against such attacks, just introduce sufficient noise.

    Note that most ATM machines allow pressing random keys while they're not ready for input. You might also want to press random keys during that time.

    I am right-handed and wear my watch on my left wrist, which works well so I can keep writing while look up the time.

    Considering left-handedness is a minority and watches are becoming less common overall by the younger generation, this will affect less and less people as time goes by. I'm usually the "old-timer" in the room that even wears a watch and knows what the term "DOS prompt" even means.

    Also, since smartwatches seem to need a recharge every single night, I don't see why this is much of a concern by anybody no matter which wrist you wear a watch on. Perhaps in the future when they finally resolve the battery life issue, it might.
