The technological advances to make our lives easier, how to open the car remote or turn keyless increased security risks, one example is a vulnerability that was discovered by researchers at the University of Birminham that allows for encoding remote key to any Volkswagen manufactured from 1995 onwards.
the problem is that data capture is relatively easy and inexpensive, researchers succeeded with an Arduino board and a radio receiver that together cost $ 40.
the researchers did not disclose the specifics for obvious reasons but if you want to alert since all they do is get two encryption keys. One is unique for each vehicle, and the other is shared. Combining them, attackers can clone the signal key owners.
For the distinctive key of each carriage enough to be within 91 meters away, and use the Arduino board with radio receiver for the signal emitted by the keychain each time they are used.
While the problem of shared key is that varies little between models, making only the four most common used by Volkswagen they can be attacked nearly 100 million vehicles manufactured in the last 20 years.
