iPhone ATM PIN code hack- HOW TO PREVENT

iPhone ATM PIN code hack- HOW TO PREVENT

so I’m making this video to show you how to protect yourself from a brand new and really easy way for a bad guy to steal your ATM PIN code with an iPhone even if you’re shielding the keypad so you can’t see you put it in and to show how hard is even to detect that it happened I’m gonna go into this store and steal somebody else’s code so watch closely to see if you can tell the moment that I actually do it so she just swiped her ATM card and she’s inputting the pin here which is the last thing you do before you finish your transaction and then I step up to make my purchase so that was it if you missed it let me play that last part over again you see as I walk up my phone does briefly hovers up with the keypad so let me explain what just happened so what I’ve got here is a device from a company called FLIR that just came out onto the market and it clips onto the back of an iPhone and it displays infrared which basically allows you to see the temperature of things here’s where it gets interesting 30 seconds ago I was sitting on this couch you probably can’t tell where but how about now but anytime two objects interact they will tend toward thermal equilibrium so they basically try and meet in the middle temperature-wise and since I’m warmer than the couch heat flows from my body to the spot on the couch where I’m sitting so this leaves behind a thermal signature because it’ll take a little time for that spot on the couch to cool back down and reach thermal equilibrium once again with the air likewise if I set my warm hand on the cold wall afterwards my hand is slightly colder but the wall is slightly warmer where I touched it and as you probably guessed by now your fingers leave a thermal signature when you type your PIN code into a debit card machine like this and as you can see in this case the PIN code was one two three four five two three four yes that’s amazing I’ve got the same combination on my luck and it gets worse because since the heat signature fades with time the bad guy could figure out the order in which the keys were pressed because the hottest button is likely the one that was pressed last and the dimmest button is likely the one that was pressed first so after doing some digging around on this I was able to find a paper that was published about this method by some researchers at UCSD several years ago according to their data they could guess the right pincode numbers 80% of the time if the image was taken right after and if the image was taken a full 1 minute later they still had a 50/50 chance of getting the numbers right scary thing is back then infrared cameras cost $10,000 and it would be really hard to discreetly sneak something of this size into the store now an infrared camera looks like an iPhone case there are a couple hundred bucks and you can get them at any Apple store however there are two pieces of good news here the first is that this won’t work on all keypads for example metal keypads reflect IR like a mirror plus they’re highly thermally conductive which dissipates the heat quickly which doesn’t allow for a thermal signature to even be left behind however I still found plenty examples of rubber and plastic buttons in my area that definitely left behind a thermal signature not to mention the other applications beyond pin codes such as door entry systems the second and this is the real point of this video is that it is really easy to defend against this by simply resting your fingers on other buttons as you type in your code as you can see here this simple precaution makes a meaningless thermal signature so spread the word because it doesn’t take any extra effort or time and it makes this potential threat a complete non-issue oh and finally if you are part of the 11% of the population whose pin code actually is 1 2 3 4 5 consider this sage advice change the combination on my luck yes

  1. How about the fact that it takes time for the heat signature to disappear and in that time 7 people used the keypad.
    How can u read that

  2. You taught me how to steal a key code and you also told me where to buy it thanks bro

  3. I was always told to touch all the buttons, especially for digicodes for doors (garage door, front door, etc.). Because we don't tend to change our codes often, we can wear out the buttons, so after a while, it can be easy to guess the numbers in the code and just try out all the combinations.
    Touching all the buttons means that you'll wear them all out, and you don't need to press other buttons because the hands heat and oils are enough to wear them out ^^

  4. When i saw this video i started rubbing my fingers against the keypad after I took out money at an atm and people looked at me weird lmao

  5. Pity you didn’t include the name/brand of the cool thermal imaging accessory for the phone. I’d like one for legitimate purposes. (Like finding heat leaks in window frames and doors.)

  6. How to avoid getting robbed by code scanner?
    Dana is for scan phone to pay
    GoPay is payment with payment connection
    OVO same as Dana but bonus cashback
    If u dont wait for payment update? Just GO TO INDONESIA

  7. I've trained myself to hold my fingers over all the keys for 30 seconds before I leave an ATM. Is it annoying to other people? Probably, but I don't care. I don't have a lot of money as it is.

  8. Please Mark. Stop the automatic translation of the titles of your videos. The title of this one, in Spanish, makes absolutely no sense.

  9. Wow, why is everyone just focused on robbing someone’s pin # instead of using this for educational purposes? Give it up, the guy is creative, smart, and handsome so maybe we can try to apply what grandma said “ if you are not going to say something nice, don’t say it at all.”

  10. I wonder: Would typing with your fingernails instead of your fingerprints also work? If so, it would be a more hygienic interaction.

  11. The people in the comments who think that a criminal having your PIN is no big deal, because they don’t yet have your card. SMH.
