CompTIA Security+ Question L-86

Which of the following attacks allows access to contact lists on cellular phones?

A. War chalking
B. Blue jacking
C. Packet sniffing
D. Bluesnarfing

Answer: D

Bluesnarfing is the theft of information from a wireless device through a Bluetooth connection. Bluetooth is a high-speed but very short-range wireless technology for exchanging data between desktop and mobile computers, personal digital assistants (PDAs), and other devices. By exploiting a vulnerability in the way Bluetooth is implemented on a mobile phone, an attacker can access information — such as the user’s calendar, contact list and e-mail and text messages -¬≠without leaving any evidence of the attack. Other devices that use Bluetooth, such as laptop computers, may also be vulnerable, although to a lesser extent, by virtue of their more complex systems. Operating in invisible mode protects some devices, but others are vulnerable as long as Bluetooth is enabled.
