DET0636 Detection of System Network Connections Discovery
AN1710 Analytic 1710
Defender observes an app (package/UID) repeatedly querying device networking context APIs (Wi-Fi scan results/current SSID/BSSID, Bluetooth device discovery, or cellular tower lists) at a rate or timing inconsistent with the app’s normal UX, often while backgrounded. Correlate API calls with permission usage (fine location, nearby devices/Bluetooth) and concurrent connectivity probes (DNS lookups/ARP/port reachability) to distinguish automated discovery from user-initiated settings checks. The detection is based on observed API execution + permission use + rate/sequence, not the specific API method name.
