“Bluesnarfing”, sometimes also called Bluejacking and Podslurping, is the exploitation of Bluetooth-enabled devices. [[ […] ]] The most infamous instance of Bluesnarfing occurred in February 2005, when a Sidekick II mobile communication device owned by the celebrity Paris Hilton was compromised. Information contained on the device, including data and images, was stolen. Bluesnarfing occurs when an individual in relatively close proximity to the victim uses a Bluetooth-enabled device to remove data from a victim with another Bluetooth-enabled device.
