Detail
Bluetooth Basic Rate / Enhanced Data Rate (BR/EDR) Core Configurations are used for low-power short-range communications. To establish an encrypted connection, two Bluetooth devices must pair with each other using a link key. It is possible for an unauthenticated, adjacent attacker to impersonate a previously paired/bonded device and successfully authenticate without knowing the link key. This could allow an attacker to gain full access to the paired device by performing a Bluetooth Impersonation Attack (BIAS). |
