Credit card PINs can be guessed even when covering the ATM pad | Bleeping Computer

Even if the target is hiding the pad with their hands, researchers have demonstrated that a special-purpose deep-learning algorithm can guess 4-digit card PINs 41% of the time. Because programming the algorithm for the specific dimensions and key spacing of the individual PIN pads is critical, the attack necessitates the creation of a copy of the target ATM. Using footage of users typing PINs on the ATM pad, the machine-learning model is then taught to recognize pad presses and assign precise probabilities to a set of possibilities. The researchers collected 5,800 films of 58 different persons from various demographics for the experiment, using 4-digit and 5-digit PINs.
