As a wirelesss technology, security is always a concern for Bluetooth communication.  The connections are typically encrypted, and the devices use frequency-hopping spread spectrum technology to jump from one frequency to another making the connection more difficult to listen in on.<ref>http://www.mobileinfo.com/Bluetooth/FAQ.htm#t1</ref> However, there are some security concerns with Bluetooth technology.  It has been found a number of different times to be vulnerable to penetration for various nefarious purposes. An early vulnerability allowed for "bluejacking," which was a method by which unauthorized messages could be sent to users. However, a more modern and concerning set of vulnerabilities is "blueborne," which enables attackers to infiltrate vulnerable devices without the user's knowledge or consent.  This attack method was developed by Armis as a proof-of-concept, which has not been released in detail for the security of everyone who uses Bluetooth 5. Mobile device manufacturers quickly got to work finding a way to patch the vulnerability.<ref name="theinquirer.net">https://www.theinquirer.net/inquirer/news/3017247/new-bluetooth-hack-doesnt-require-pairing-with-victims-device</ref><br />

The underlying concern with Bluetooth is that to offer the functionality it does, it needs system access on its host device greater than that of even the user.<ref name="theinquirer.net">https://www.theinquirer.net/inquirer/news/3017247/new-bluetooth-hack-doesnt-require-pairing-with-victims-device</ref> If exploited, it offers a great deal of access into the device's system, and much harm could be done, or information stolen.
