AI-Powered Thermal Imaging Enables ATM PIN Theft
Researchers at the University of Glasgow have demonstrated a method called ThermoSecure that uses thermal imaging cameras combined with artificial intelligence to reconstruct ATM PIN codes by analyzing heat signatures on keypad buttons. The technique achieves 86% accuracy within 20 seconds of PIN entry, with 76% accuracy at 30 seconds.
What happened
Researchers at the University of Glasgow developed a system called ThermoSecure that uses thermal imaging and artificial intelligence to reconstruct ATM PIN codes.
The system records temperature differences on ATM keypad buttons using a thermal camera after PIN entry, and AI software determines which buttons were pressed and in what order.
Reported impact
Test results showed the method achieves 86 percent accuracy within 20 seconds of PIN entry, and 76 percent accuracy at 30 seconds, representing significant fraud risk.
Security researchers noted the technology is easily accessible to criminals and provided guidance on protective measures including covering the keypad, allowing buttons to cool, using contactless payment, and inspecting ATMs for tampering.
