What is Bluesnarfing?

If we talk about the Bluesnarfing attack then it is a much more serious attack than bluejacking which is more of a practical joke that does not alter any data loose.
Blusnarfing allows the hacker to take complete control of the device and access many of the functions and all of the data in the device. The hacker is able to make calls and texts, listen to conversations and remove all information without the phone’s owner being alerted.
