Bluejacking vs. Bluesnarfing — What's the Difference?

Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the name field (i.e., for bluedating or bluechat) to another Bluetooth-enabled device via the OBEX protocol. Bluetooth has a very limited range, usually around 10 metres (32.8 ft) on mobile phones, but laptops can reach up to 100 metres (328 ft) with powerful (Class 1) transmitters.

Bluesnarfing is the unauthorized access of information from a wireless device through a Bluetooth connection, often between phones, desktops, laptops, and PDAs (personal digital assistant). This allows access to calendars, contact lists, emails and text messages, and on some phones, users can copy pictures and private videos.

The act, practice, or activity of sending anonymous text messages to a mobile phone using Bluetooth.

Unauthorized access to the information on a wireless device through a Bluetooth connection, often between phones, desktops, laptops, or PDAs.
