• Rogue Access Point
• Evil Twin
• Bluesnarfing
• Bluejacking 

EXPLANATION

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).
Bluebugging goes far beyond bluejacking and bluesnarfing! This is an advanced bluetooth device hacking technique by taking control of other Bluetooth enabled mobile phones or mobile devices to make call, send short message, read and write phonebook, etc.
