A Bluetooth Low Energy (BLE) vulnerability allows spoofing attacks that could affect the way humans and machines carry out tasks. The BLESA flaw affects the reconnection process that occurs when a device moves back into range after losing or dropping its pairing, Purdue researchers said. A successful BLESA attack allows bad actors to connect with a device (by getting around authentication requirements) and send spoofed data to it. For humans, attackers could feed a device deceptive information about how it behaves.
