Bluetooth is a crucial part of our device usage these days. It helps you connect devices wirelessly and transfer data between two devices.

Because of this issue, it says, attackers can access the security keys between two Bluetooth devices. And by doing that, they will be able to connect with any Bluetooth device in their vicinity. The issue was reported in the Cross-Transport Key Derivation (CTKD). This component is responsible for setting up authentication keys while pairing two devices.

Using this, devices can decide which Bluetooth standard they want to connect with. But because of BLURtooth, attackers can exploit the issue to take control of the CTKD. They can also overwrite the authentication keys to weaken the encryption between the devices. This way, attackers can not only push malicious data through Bluetooth to the targeted devices. They can also access the data made available through the transmission. Also Read – Xiaomi Mi eBook reader passes Bluetooth certifications

While the 5.1 standard has a safety mechanism built-in to fight this vulnerability. The concerning part is, manufacturers are yet to inform the users about this issue. And because of this, a patch to fix the issue is yet to be rolled out. We’re hoping that is done by the OEMs right away.
