For iOS, detect Indicator Removal on Host from documented management, network, or vetting evidence; treat state queries as periodic observations rather than real-time events. Correlate Application Permission via Application Vetting [Code-signing entitlements and Info.plist privacy usage-description keys]; OS API Execution via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: App invokes file deletion, container-local database truncation, or cache-clear operations on supervised device within $CleanupWindow$ of prior data access or upload event]; System Settings via Apple MDM [DeviceInformation / SecurityInfo / ProfileList / restrictions and compliance queries]. 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.

Field Description
ApprovedCleanupApps Privacy cleaner apps approved by IT, MDM agent for managed wipe. Derive from MDM catalog. Tightening: MDM agent only — all other post-exfil cleanup is anomalous.
CleanupWindow Default 300s after exfiltration event (network upload) within which subsequent cleanup is causally linked. Tightening: 60s — immediate post-exfil cleanup.

For Android, detect Indicator Removal on Host 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]; OS API Execution via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: App invokes file deletion, database truncation, log clearing, or app-data-clear operations within $CleanupWindow$ of prior data access or network exfiltration event — post-exfil cleanup chain]; System Settings via Android Enterprise DPC [DevicePolicyManager policy/compliance/security-state queries and SecurityLog events where supported]. 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.
