Welcome back to our ongoing journey into the fascinating realm of Apple’s BLE-powered services! In our previous posts, we’ve explored the foundational concepts of Bluetooth Low Energy (BLE) and delved into the intricacies of Apple’s innovative FindMy service. Today, we’re going to take a closer look at the darker side of FindMy: the potential for abuse by malicious actors. There are three distinct categories of abuse we’ll look at today.

Direct Tracking

Imagine a scenario where a small tracker discreetly attaches to a person or object - think someone placing an AirTag in your backpack. With Apple devices nearby creating location reports, an attacker could easily track the movement of the individual or item with the high precision FindMy is known for. This abuse-case poses a significant privacy risk, which is not adequately addressed by Apple’s Unwanted Tracking Detection feature.
