Which Bluetooth attack involves sending unsolicited messages?

The attack that involves sending unsolicited messages is known as Bluejacking. This technique allows an attacker to send messages or files to another Bluetooth-enabled device without the target's consent. The attacker typically takes advantage of devices that are discoverable and not adequately secured.

Bluejacking often manifests as the unsolicited transmission of text messages or contact information, often used for harmless pranks or advertising purposes. It utilizes the basic functionality of Bluetooth to reach out to nearby devices, making it accessible and relatively easy to execute.

The nature of Bluejacking is primarily about the unsolicited aspect of communication, differentiating it from other Bluetooth vulnerabilities that focus more on data theft or unauthorized access. For example, Bluebugging involves taking control of a device and potentially accessing the phone's features and data; Bluesnarfing is specifically about stealing information from a phone. Bluehacking is not as widely recognized and does not describe a specific type of Bluetooth attack in the same context.

Understanding the differences in these terms can help in recognizing how various Bluetooth attacks operate and the types of risks they pose to users.
