Thwarting NFC virtual pickpockets
It’s the end of a long week in New York. A weary securities industry executive is riding the elevator down from the 57th floor to head home, her purse slung over her shoulder. On the 54th floor, another woman boards an elevator. As the car fills at subsequent stops, the women are crowded together. When their purses touch, the executive has no idea the corporate identity badge she uses to access her office is being hacked, although it’s never left her handbag. Later that weekend, the woman from the 54th floor gains access to the 57th floor simply by using her phone with the stolen credentials at the entryway card reader.
