For Android, detect Process Injection by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Host Status via Android Enterprise DPC [DevicePolicyManager policy/compliance/security-state queries and SecurityLog events where supported]; Network Traffic Flow via Android Enterprise Network Logging / Enterprise VPN [DevicePolicyManager.retrieveNetworkLogs(): DnsEvent / ConnectEvent; VPN flow metadata]; Process Access via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: accessibility_service or notification_listener appears attributed to a bundle IN $LegitimateSystemProcesses$ within $InjectionWindow$ of root detection — injected code requesting special permissions under a legitimate system process identit]. 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.

Mutable Elements
Field Description
LegitimateSystemProcesses com.android.systemui, android.process.media, com.android.phone — high-value injection targets.
InjectionWindow Default 600s after root detection.
ProcessBaselineDomains Per-process network destination baseline for system processes.

For iOS, detect Process Injection by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Host Status via Apple MDM [DeviceInformation / SecurityInfo / ProfileList / restrictions and compliance queries]; Network Traffic Flow via Apple Network Extension / Enterprise VPN [NEFilterFlow / per-app VPN / secure-web-gateway flow metadata]; Process Access via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: kernel log entry at level=fault referencing task_for_pid or get-task-allow violation on SUPERVISED device with Unified Log forwarding — kernel records entitlement violations at fault level; requires supervised MDM with Unified Log export]. 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.
