Researchers found a fundamental problem with Bluetooth security

A new Bluetooth device security warning has been issued following the discovery of a critical problem that researchers see as a serious threat to users’ security and privacy.

Through this security problem, an attacker can interfere with the process of encrypting network connections thus stealing the encryption keys and accessing traffic data between the targeted devices.

The team was surprised by finding of such a fundamental problem that has been present for 20 years.

All Bluetooth models from 1.0 to 5.1 are affected by this security problem. It was discovered by CISPA researchers and published in coordination with companies such as Microsoft, Apple, Intel, Cisco and Amazon.

All chips made by Intel, Broadcom, Apple and Qualcomm are vulnerable to KNOB attacks. Imagine beyond Bluetooth headsets and speakers, all those printers or data exchanges between devices or between your phone and your car.
