Bluejacking

https://en.wikipedia.org/wiki/Bluejacking

Bluejacking is a Bluetooth-based attack technique that involves sending unsolicited messages to users of Bluetooth-enabled devices without the recipient's consent.

Here is a detailed explanation of Bluejacking:

Mechanism and Purpose

• Definition: Bluejacking is the practice of sending unsolicited messages over a wireless connection using Bluetooth.
• Method: This technique typically involves sending a digital business card (vCard) via the OBEX protocol to a nearby Bluetooth-enabled device (such as mobile phones, PDAs, or laptop computers). The message intended for the victim is usually contained within the name field of the vCard.
• Content: While bluejackers typically send only a text message, modern phones also make it possible to send images or sounds.
• Applications: Bluejacking has been utilized in guerrilla marketing campaigns to promote advergames.

Impact and Distinction from Other Attacks

• Harmfulness: Bluejacking is generally considered harmless. However, a bluejacked person may believe their phone is malfunctioning because they are unaware of what has happened.
• Comparison to Bluesnarfing: Bluejacking is often confused with Bluesnarfing. The key difference lies in the action performed:
  • Bluejacking transmits data to the target device.
  • Bluesnarfing is the theft of information (such as contact lists, emails, and text messages) from a wireless device via a Bluetooth connection.

To solidify the distinction: Think of Bluejacking as slipping an unsolicited note (the vCard message) into someone's digital mailbox, whereas Bluesnarfing is picking the lock and stealing information from the mailbox.
