Real-World Weaknesses | Awareness Series: Part 1 of 3 Over the next few posts, I will explore the real cybersecurity risks behind Bluetooth and why individuals, homeowners and businesses routinely overlook this attack surface. Bluetooth is often treated as harmless background technology. In reality, it can reveal device presence, proximity, movement patterns and, in some cases, weak implementation choices that increase exposure. Classic Bluetooth vs BLE Classic Bluetooth is typically used for audio devices and higher-bandwidth data transfer. Bluetooth Low Energy, or BLE, is commonly used by beacons, trackers, wearables, IoT devices, smart locks and sensors. Both operate in the crowded 2.4 GHz ISM band. Both can broadcast information into the surrounding environment. That means both can create exposure, often without the user realising.
