The network name and BSSID can be used to geolocate users via a lookup against a database of BSSID such as WiGLE or SkyHook. However, by listening to these broadcasts, any application on the device can capture this information thus bypassing any permission checks and existing mitigations.īecause MAC addresses do not change and are tied to hardware, this can be used to uniquely identify and track any Android device even when MAC address randomization is used. 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. This includes the WiFi network name, BSSID, local IP addresses, DNS server information and the MAC address. System broadcasts by Android OS expose information about the user’s device to all applications running on the device. : Public disclosure minor syntax updates 1 Comment : Fix confirmed, communication regarding disclosure : Communication from the vendor, issue still being reviewed : Report triaged and being reviewed by the vendor Text of the advisory written by Yakov Shafranovich.
