What term describes the attack where unwanted text messages are received in crowded areas and cease when leaving?

The term that accurately describes the situation where unwanted text messages are received in crowded areas and stop when leaving is bluejacking. This type of attack involves sending unsolicited messages over Bluetooth to nearby devices, typically in places with a high concentration of people, such as public transportation or events. The messages are sent as the devices establish a temporary Bluetooth connection, which means that the unwanted messages will terminate once the individual moves out of range of the sender's Bluetooth signal.

In contrast, phishing refers to attempts to deceive individuals into providing sensitive information online, while smishing involves phishing attempts conducted via SMS. Vishing is a voice phishing attack where attackers manipulate individuals over the phone to gain confidential information. These terms represent different forms of social engineering or attack vectors, but they do not align with the specific behavior associated with bluejacking, which is primarily a localized Bluetooth exploitation tactic.
