Bluetooth Security and Exploitation

Bluetooth Security and Exploitation is the specialized field concerned with both defending and compromising the Bluetooth wireless protocol. It examines the protocol's inherent security mechanisms, including pairing for authentication and encryption for confidentiality, while simultaneously investigating vulnerabilities that arise from flaws in the protocol stack, device implementations, or user configurations. This leads to a range of attacks, from classic exploits like Bluesnarfing (unauthorized data access) and Bluebugging (remote device control) to modern threats against Bluetooth Low Energy (BLE). As this technology is integral to a vast ecosystem of devices including smartphones, wearables, and the Internet of Things (IoT), understanding its security landscape is critical for preventing data theft, eavesdropping, and device hijacking.
