Smartwatch Motion Tracking Malware Could Steal PIN Codes

A Copenhagen computer engineering student has demonstrated a technique that could allow attackers to steal keypad login credentials by tracking a user’s hand movements using malicious code running on a smartwatch. The technique, detailed in a master’s thesis by French student Tony Beltramelli at the University of Copenhagen, builds on earlier work by Romit Roy Choudhury, associate professor at the Department oF Electrical and Computer Engineering of the University of Illinois, who last year demonstrated how a Samsung Gear Live smartwatch’s motion sensors could be used to log a user’s keystrokes on a standard computer keyboard. Keypad spying Beltramelli’s work goes a step further, using machine learning techniques to try to predict a user’s input in a 12-digit keypad of the kind used in cash machines or smartphone login screens.…
