For Android, detect Compromise Client Software Binary from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events. Correlate File Metadata via Application Vetting / Forensic Acquisition [Dynamic filesystem trace or acquired app-container/filesystem artifacts: file hash changes for binary at $SystemBinaryPaths$ relative to known-good baseline — hash deviation confirms modification]; File Modification via Application Vetting / Forensic Acquisition [Dynamic filesystem trace or acquired app-container/filesystem artifacts: write() to path IN $SystemBinaryPaths$ by process NOT IN $TrustedUpdateSources$]; Process Creation via Application Vetting / Managed Device Telemetry [execve() of modified binary (hash != baseline) — execution of modified binary is the persistence activation]. 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 |
|---|---|---|
| File Metadata (DC0059) | mobile:ForensicArtifacts | Dynamic filesystem trace or acquired app-container/filesystem artifacts: file hash changes for binary at $SystemBinaryPaths$ relative to known-good baseline — hash deviation confirms modification |
| File Modification (DC0061) | mobile:ForensicArtifacts | Dynamic filesystem trace or acquired app-container/filesystem artifacts: write() to path IN $SystemBinaryPaths$ by process NOT IN $TrustedUpdateSources$ |
| Process Creation (DC0032) | mobile:DynamicAnalysis | execve() of modified binary (hash != baseline) — execution of modified binary is the persistence activation |
| Field | Description |
|---|---|
| SystemBinaryPaths | /system/bin/, /system/xbin/, /system/vendor/bin/. Vary by OEM. |
| TrustedUpdateSources | OTA update service, MDM agent. Derive from MDM platform documentation. |
| BinaryHashBaseline | Known-good hash per binary per Android version. Update on each OS release. |
For iOS, detect Compromise Client Software Binary by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate File Metadata via Application Vetting / Forensic Acquisition [Dynamic filesystem trace or acquired app-container/filesystem artifacts: MDM supervised integrity_check=fail following jailbreak detection — integrity check failure on supervised Jamf/Intune enrolled device indicates filesystem modifications beyond passive jailbreak presence]; 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.
