DET0672 Detection of Web Service

AN1770 Analytic 1770

The defender correlates outbound communication from an application or service to legitimate external web platforms with mobile runtime context showing that the communication is inconsistent with the app's approved role, expected destinations, user interaction pattern, or device state. The strongest Android evidence is a managed or installed app communicating with cloud storage, social, messaging, code-hosting, or generic HTTPS web-service infrastructure shortly after background activation, protected-resource use, or local staging activity, especially when the device is locked, user interaction is absent, or the app's historical network baseline does not include that service class.

AN1771 Analytic 1771

The defender correlates communication to legitimate external web-service platforms with supervised managed-app context and device-state information showing that the traffic is inconsistent with the app's expected role, background-refresh profile, or user interaction timing. On iOS, the strongest reliable evidence is network telemetry tied to a managed app or device plus app state and supervision context, especially when traffic to social, collaboration, cloud-storage, or generic HTTPS platforms occurs shortly after background activity, while the device is locked, or without expected user-driven foreground execution. Direct low-level framework visibility is weaker than Android, so primary analytic confidence should be anchored to supervised app context plus network behavior rather than assumed host-level proof.
