Final answer:
Bluesnarfing is the unauthorized access of information from a wireless device through a Bluetooth connection, where a hacker can copy sensitive data without consent.
Step-by-step explanation:
The unauthorized access of information from a wireless device through a Bluetooth connection is called Bluesnarfing. Bluesnarfing is an attack where a hacker gains unauthorized access to a device via its Bluetooth connection, allowing them to copy information such as contact lists, calendars, and other sensitive data without the user's permission. This is different from Bluebugging, which involves taking control of a phone to make calls, send messages, etc., Bluejacking, which is the practice of sending unsolicited messages over Bluetooth to nearby devices, and Bluesmacking, which is a Bluetooth-based Denial of Service (DoS) attack.
