Wireless Security Testing - Bluetooth

Wireless Security Testing focused on Bluetooth examines vulnerabilities in this widely-used short-range wireless technology. Bluetooth connects devices like smartphones, headsets, and IoT gadgets, making it a potential attack vector. The testing process typically involves: 1. Reconnaissance: Identifying Bluetooth-enabled devices, their discovery modes, and visible names. Tools like Bluez, hcitool, or specialized hardware like Ubertooth can scan for devices even when not in discoverable mode. 2. Enumeration: Gathering information about detected devices, including device class, services offered, and manufacturer details. 3. Vulnerability scanning: Testing for known issues like BlueJacking (sending unsolicited messages), BlueSnarfing (unauthorized access to data), and BlueBugging (taking control of device functions). 4. Testing authentication: Analyzing pairing mechanisms, PIN security, and addressing vulnerabilities in legacy pairing modes. 5. Assessing encryption: Checking implementation of Bluetooth encryption, especially for earlier versions with weaker security. 6. Testing for MITM attacks: Attempting man-in-the-middle attacks to intercept communications between paired devices. 7. Firmware analysis: Examining device firmware for implementation flaws. Modern security concerns include: - KNOB Attack: Forces devices to use minimal encryption strength - BIAS Attack: Exploits authentication weaknesses - BlueBorne: Allows attacker to compromise devices via air-gapped vectors Pentesting tools often include Bluetooth-specific utilities like: - BtleJack/Gattacker for BLE attacks - Bluetooth Sniper Rifle for long-range testing - Wireshark with appropriate plugins Effective testing concludes with remediation recommendations such as using the latest Bluetooth versions, keeping firmware updated, limiting discoverability, using strong PINs, and implementing additional application-layer encryption for sensitive data.
