Turning on the Bluetooth on your mobile device enables other Bluetooth-enabled devices to see your mobile device, and possibly make connections with it. It could allow an attacker to install malware through that connection, or secretly activate a microphone or camera to eavesdrop on the user.
- Turn off Bluetooth if it’s not being used.
- Do not leave the Bluetooth in ‘discoverable mode’ or ‘open’. This could allow an attacker to install malware through that connection.
- Do not accept any data transfer from anyone you are not familiar with.
