What term describes unsolicited messages sent to Bluetooth-enabled devices?

The term that describes unsolicited messages sent to Bluetooth-enabled devices is bluejacking. Bluejacking is a practice where a user sends a message to a nearby Bluetooth-enabled device without prior consent from the recipient. This is typically done by sending a contact card with a message to another device that is discoverable and within range, allowing the sender to engage in a form of harmless communication or a light-hearted prank.

In contrast, bluesnarfing involves unauthorized access to information on a Bluetooth-enabled device, such as contacts, calendar events, or messages. BlueBorne is a more sophisticated attack vector that exploits vulnerabilities in Bluetooth to take control over devices or access data without user interaction. Tethering refers to the process of connecting one device to another, usually to share an internet connection, which does not have any direct relevance to unsolicited messages.

Overall, bluejacking is characterized by its benign and unsolicited nature, which is why it is the correct term for the scenario described.
