BLEKey Device Breaks RFID Physical Access Controls

A device the size of a quarter that can be installed in 60 seconds on a proximity card reader could potentially be used to break physical access controls in 80 percent of deployments.The device, dubbed BLEKey, is used to read cleartext data sent from card readers to door controllers to either clone cards or feed that data to a mobile application that can be used to unlock doors at any number of installations. The hack unveiled at Black Hat is worrisome for facilities reliant on proximity cards and readers for access to buildings in critical industries or enterprises.
