Researchers have disclosed a new attack method that can be leveraged to track mobile devices that rely on Media Access Control (MAC) address randomization to protect users’ privacy.
A MAC address is a unique identifier assigned to a device’s network interfaces. Since the address is unique and hardcoded, it can be very useful for tracking a device and its owner. In order to protect users against MAC-based tracking attempts, mobile device vendors have implemented MAC address randomization, which involves broadcasting a random Wi-Fi MAC address.
