phone proof of concept viruses and have actually infected a few
Bluetooth does have many built in features which help protect a
user from being hacked. First is distance, unlike WI-FI Bluetooth
travel only at most 10 meters. Next, Bluetooth uses frequency hopping
and 128 encryption can be enabled. Other features of Bluetooth are
