A new vulnerability dubbed “BlueBorne” has been discovered in Bluetooth that can potentially allow an attacker to remotely take over electronic devices including phones, computers and even some Internet of Things devices like smart TVs and watches. Please note that attackers must be in close proximity (within 10 meters for most devices) of the device in order for this attack to work, so threats from overseas or long distances are not really an issue at this point in time.
Most major operating systems such as Windows, macOS, iOS, Android, Linux, etc. are not vulnerable if they are updated to the latest version. To determine if your device is vulnerable, you can check the page from the researchers who disclosed the issue here:
If you are unsure how to update a device, please check the manufacturer’s website for instructions. If there is no update available for your device that will close the vulnerability, you can disable Bluetooth if you do not require it.
