Your Smart Watch Could Betray The PIN Code of Your Card

Professor Wang Yan is not connected watch. The reason? They are a nightmare for cyber security expert. To convince us, the researcher has developed with his team a way to recover our credit card codes, simply with a smartwatch.

If the arguments that push us to temper the heat of connected watch manufacturers are logical and practical, we imagined not necessarily malicious hijacking could be made. At least not at this point.

To impress their world during the 11th conference of the ASIACCS to Xi’ year, in China, the Professor Yan Wang and his team have made a confusing experience that they explain in a study published for the occasion.

The team of researchers came to guess the Bank owners smartwatch code while the latter withdrawing cash on ATMs (A.T.M.). How? Fully using the sensors of positions and movements present at the wrists of the participants, in their smart watch.

Watches and other bracelets connected have sensors to deliver health information, whether on the quality of sleep or the physical efforts made in the day. But if the data is accessible, the gyroscope can also be used by hackers to reproduce the trajectories of hands in given situations, in order to find the code on a keyboard by inversion…

It is precisely the experiment conducted by the researchers, who decided to prove that with only a smart watch, they could guess and find bank codes to those who wear watches when they go to a Distributor.

With A Little Imagination, There Are Infinite Ways To Harvest Sensitive About Us Data

To test his hypothesis, Professor Wang has made a particular algorithm, which, from the sensor data, would be able to guess the codes typed on distributors. Experimentation will be allowed for a test more than 80% of success in the exercise of prediction of the codes, and after three tries, the algorithm guess more than 90% of the banking codes.

The study says that this assumption of attack is certainly not simple, but the results obtained by researchers should give pause for thought on the vulnerability of our connected objects. With a little imagination, there are infinite ways to harvest sensitive about us data.

Finally, the study says that such data, those sensors, can be retrieved on the user’s smartphone with malware or by intercepting the Bluetooth communication between the smartphone and the watch. Experience illuminates so on some weaknesses, however the assumption to see tomorrow such attacks happen in reality is quite thin.
