T1422 System Network Configuration Discovery

Adversaries may look for details about the network configuration and settings, such as IP and/or MAC addresses, of operating systems they access or through information discovery of remote systems.

On Android, details of onboard network interfaces are accessible to apps through the class.1 Previously, the Android TelephonyManager class could be used to gather telephony-related device identifiers, information such as the IMSI, IMEI, and phone number. However, starting with Android 10, only preloaded, carrier, the default SMS, or device and profile owner applications can access the telephony-related device identifiers.2

On iOS, gathering network configuration information is not possible without root access.

Adversaries may use the information from System Network Configuration Discovery during automated discovery to shape follow-on behaviors, including determining certain access within the target network and what actions to do next.
