DET0707 Detection of Scheduled Task/Job

AN1829 Analytic 1829

The defender correlates creation or registration of deferred, repeating, or constraint-based background work with later task execution in the same app context, especially when the task executes without recent user interaction, from background state, or with follow-on file, sensor, or network behavior inconsistent with the app's declared role. The analytic prioritizes Android-observable control-plane effects: WorkManager enqueue operations, JobScheduler or AlarmManager scheduling, later wake or execution of the scheduled work, and post-trigger activity such as network sessions, local staging, or sensor access.

AN1830 Analytic 1830

The defender correlates creation of background scheduler activity with later execution of repeating or deferred work by the same managed app, then raises confidence when the triggered activity produces network, local-write, or other app behavior that occurs outside expected user context. Because iOS exposes weaker direct scheduling observability in many enterprise environments, the analytic anchors first on managed app posture and lifecycle-to-network or lifecycle-to-file effects, with NSBackgroundActivityScheduler-related behavior treated as strongest when runtime telemetry can observe background scheduler usage or execution callbacks.
