Ethical Hacking Essentials Practice Test

Identify the type of attack performed when an attacker eavesdrops on Bluetooth paired devices to intercept data transfer?

1. Bluejacking

2. KNOB attack

3. Bluesnarfing

4. Bluesmacking

The correct answer is: KNOB attack

The correct identification of the attack when an attacker eavesdrops on Bluetooth paired devices to intercept data transfer is Bluesnarfing. This term refers specifically to the unauthorized access of information from a Bluetooth-enabled device, allowing an attacker to intercept data such as contacts, messages, and files without the user's consent. Bluesnarfing typically exploits vulnerabilities found in Bluetooth connections, particularly when devices are not configured securely. This kind of attack often targets devices that might have their Bluetooth settings set to 'discoverable' or have not been updated to patch known security flaws. Other options reflect different forms of Bluetooth-related attacks. For example, Bluejacking involves sending unsolicited messages to Bluetooth-enabled devices, while the KNOB attack can manipulate encryption keys in a Bluetooth session. Bluesmacking, on the other hand, is a denial-of-service attack that overwhelms a Bluetooth device. Each of these terms refers to different methods and objectives concerning Bluetooth security vulnerabilities, clarifying why Bluesnarfing is the focus in the context of intercepting data transfer.
