For Android, detect SMS Messages by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate API Calls via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: ContentResolver.query(Telephony.Sms) including both inbox]; Network Traffic Flow via Android Enterprise Network Logging / Enterprise VPN [DevicePolicyManager.retrieveNetworkLogs(): DnsEvent / ConnectEvent; VPN flow metadata]; Permissions Request via Android Enterprise DPC / Application Vetting [DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review]. 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.

| API Calls (DC0112) | mobile:DynamicAnalysis | Dynamic API/runtime trace: ContentResolver.query(Telephony.Sms) including both inbox |
| Network Traffic Flow (DC0078) | android:EnterpriseNetworkLog | DevicePolicyManager.retrieveNetworkLogs(): DnsEvent / ConnectEvent; VPN flow metadata |
| Permissions Request (DC0116) | android:DevicePolicyManager | DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review |
| Field | Description |
|---|---|
| ApprovedSMSApps | Default SMS app, approved SMS backup apps. Keep minimal. |
| SMSUplinkThreshold | Default 10KB — SMS messages are ~500 bytes; even 20 with 2FA codes is high-confidence exfil. |
| AppCDNList | Per-app CDN. Derive by measurement. |
| ExfilWindow | Default 120s. |
For iOS, detect SMS Messages by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Application State via Apple MDM [InstalledApplicationList / ManagedApplicationList]; 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]. 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 State (DC0123) | iOS:MDM | InstalledApplicationList / ManagedApplicationList |
| Host Status (DC0018) | iOS:MDM | DeviceInformation / SecurityInfo / ProfileList / restrictions and compliance queries |
| Network Traffic Flow (DC0078) | iOS:NetworkExtension | NEFilterFlow / per-app VPN / secure-web-gateway flow metadata |
| Field | Description |
|---|---|
| MessagingAppList | Messages (SMS), WhatsApp, Signal, Telegram — apps that use sms.db or have message value. |
| SMSDumpThreshold | Default 10KB — even high-value targeted message grabs are small; full inbox dumps are larger. |
| AppCDNList | Per-device CDN baseline. |
| ExfilWindow | Default 300s. |
