Russian researchers have demonstrated how ATMs could be hacked – without installing malware. They say they successfully programmed a credit-card-sized Raspberry Pi computer to the inside of an ATM. The device can, for example, intercept PIN codes, send directions directly to different components inside the ATM enclosure, telling them to dispense cash or open the safes in which the cash is stored. The researchers say they have disclosed related vulnerabilities directly to ATM manufacturers, but they declined to specify the machines they tested.”]
