"Bluetooth Bug Opens Devices to Man-in-the-Middle Attacks"

Researchers at Purdue University have discovered a flaw they are calling "BLURtooth." The high-severity Bluetooth vulnerability exists in the pairing process for Bluetooth 4.0 through 5.0 implementations. The vulnerability could allow an unauthenticated adversary within wireless range (330 feet for Bluetooth 4.0 devices, and 800 feet for Bluetooth 5.0) to eavesdrop or alter communications between paired devices.
