Someone can unlock your phone, smart locks and car by using this flaw

This vulnerability affects hundreds of thousands of Bluetooth Low Energy (BLE) devices.

Mobile phones, smart watches, laptops, smart locks, and even cars might all be compromised via a newly identified weakness in the Bluetooth Low Energy (BLE) protocol.

By exploiting the hole uncovered by the NCC Group, the first link layer relay assault was successfully carried out

Bluetooth proximity authentication systems (which are used to unlock devices within a particular range) can be easily hacked using cheap off-the-shelf hardware
