Turn off the ‘Bluetooth‘ option on your smartphone or laptop if not needed. If you keep Bluetooth on all the time, your device may be hacked. Cyber Security experts warn that those who keep Bluetooth on their smartphones or laptops all the time should give up that habit.
This is because there is a security flaw in the Bluetooth Protocol, which cyber criminals can use to steal important information or hack devices and cause havoc.
welivesecurity.com A report says a team of academics has uncovered a new vulnerability in the Bluetooth wireless communication protocol that carries out ‘bluetooth impersonation attacks‘ on various devices such as smartphones, laptops and smart-home devices.
Devices that have previously been ‘paired’ with Bluetooth can be exploited by cyber criminals to take advantage of Bluetooth vulnerabilities. Bluetooth devices that currently support Bluetooth Basic Rate (BR) or Enhanced Data Rate (EDR) Core Configuration 5.2 or higher are at risk. Usually a link key has to be ‘paired’ to establish an encrypted connection between the two devices.
Experts say you need to have an updated Bluetooth configuration to protect yourself from such attacks. Otherwise device manufacturers will have to wait until the firmware update. As long as the firmware is not being updated, the Bluetooth option should be turned off without the need to pair it with another device for protection.
According to the Cyber Emergency Response Team of India, cyber criminals can enter a device via Bluetooth, hiding their identities, if they want to. Miscreants can take full access to the device by exploiting the weakness of Bluetooth.
