System broadcasts by Android OS expose information about the user's device to all applications running on the device. This includes the WiFi network name, BSSID, local IP addresses, DNS server information and the MAC address. Some of this information (MAC address) is no longer available via APIs on Android 6 and higher, and extra permissions are normally required to access the rest of this information. However, by listening to these broadcasts, any application on the device can capture this information thus bypassing any permission checks and existing mitigations.
