For Android, detect One-Way Communication by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Application Permission via Android Enterprise DPC / Application Vetting [DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review]; Application State via Android Enterprise / EMM [Managed package inventory/status and package metadata]; Network Traffic Content via Enterprise Secure Web Gateway / Proxy [DNS/HTTP(S) inspection or proxy transaction metadata where enterprise decryption/inspection is deployed]. Alert on a sequence or state change inconsistent with the device/app baseline, approved management policy, or expected user workflow; do not infer unobserved API calls, file/process activity, or payload content from management state alone.
| Data Component | Name | Channel |
|---|---|---|
| Application Permission (DC0114) | android:DevicePolicyManager | DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review |
| Application State (DC0123) | android:EMM | Managed package inventory/status and package metadata |
| Network Traffic Content (DC0085) | webproxy:applog | DNS/HTTP(S) inspection or proxy transaction metadata where enterprise decryption/inspection is deployed |
| Field | Description |
|---|---|
| ApprovedPlatformApps | Apps approved for periodic read access to each platform. News readers (RSS/social), weather apps — legitimate pollers. Unknown apps periodically polling paste/code platforms are anomalous. |
| PollingIntervalThreshold | Default 900s (15 min) maximum interval between fetches to same platform from background. More frequent background polling without user activity = C2 check-in. |
| CommandProcessWindow | Default 30s between platform content retrieval and behavioral change (new connection, file write). Command processing is near-synchronous. |
For iOS, detect One-Way Communication by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Application Permission via Application Vetting [Code-signing entitlements and Info.plist privacy usage-description keys]; Application State via Apple MDM [InstalledApplicationList / ManagedApplicationList]; Network Traffic Content via Enterprise Secure Web Gateway / Proxy [DNS/HTTP(S) inspection or proxy transaction metadata where enterprise decryption/inspection is deployed]. Alert on a sequence or state change inconsistent with the device/app baseline, approved management policy, or expected user workflow; do not infer unobserved API calls, file/process activity, or payload content from management state alone.
