T1632 Subvert Trust Controls — Attack Simulation

Adversaries may undermine security controls that will either warn users of untrusted activity or prevent execution of untrusted applications. Operating systems and security products may contain mechanisms to identify programs or websites as possessing some level of trust.

Complete technique description

Adversaries may undermine security controls that will either warn users of untrusted activity or prevent execution of untrusted applications. Operating systems and security products may contain mechanisms to identify programs or websites as possessing some level of trust. Examples of such features include: an app being allowed to run because it is signed by a valid code signing certificate; an OS prompt alerting the user that an app came from an untrusted source; or getting an indication that you are about to connect to an untrusted site. The method adversaries use will depend on the specific mechanism they seek to subvert.

Detection telemetry and configuration

These contracts are selected through exact technique-to-data-component relationships or explicitly labelled planning overrides. Configure a collector at the relevant observation point; a telemetry name alone is not coverage.

Application Permission · source-mapped

DC0114 collection page — Compare manifest declarations with runtime granted state using authorized package inspection and own-app permission checks.

Providers and collection configuration

  • Android logcat: Permitted logs from a consented test device/emulator; output depends on build, permissions and instrumentation.
  • Android dumpsys: Point-in-time service/package state on an authorized development device.
  • Instrumented test application: Own-app permission, API and state callbacks; not universal visibility into other apps.
  • Use a disposable emulator or owned development device with approved debugging. Record OS/API level, app version and instrumentation privileges.
  • Collect only relevant logcat buffers/tags and service snapshots; add explicit own-app instrumentation for events absent from OS logs.
  • Forward sanitized logs and compare before/after state. Remove test data and revoke debugging access after the lab session.

Required normalized fields: package, permission, declared, granted.

adb shell dumpsys package test.example.lab

Read-only snapshot on a consented debug device. Replace the example package with your owned test app. Output and access vary by Android build; this is not a permission-request event stream.

Illustrative collection event

Project-normalized synthetic JSON, not a native provider log, captured event, attack verdict or validated detection. A parser/adapter is required for a real SIEM. Example names, IPs and values are fictional.

Visibility limits: Android tooling does not imply iOS coverage. Standard mobile apps cannot observe all other apps or protected OS internals; MDM status is not full API, filesystem or content telemetry.

File Creation · source-mapped

DC0039 collection page — Scope Sysmon FileCreate (11) to the lab directory; retain the process and file path. Differentiate creation/overwrite if the sensor can.

Providers and collection configuration

  • Microsoft Sysmon: Windows event-based collection; enable the event types needed below.
  • Linux Audit: Linux alternative for supported system-call and file events; different semantics and fields.
  • Apple Endpoint Security clients: macOS alternative where the subscribed event exists; requires an entitled, approved client, not an iOS collector.
  • On a disposable Windows host, review the installed Sysmon schema and current configuration; merge scoped event filters into the existing policy rather than replacing it.
  • Forward Microsoft-Windows-Sysmon/Operational to the lab collector. Preserve event ID, timestamp, computer, process identifiers and the original event.
  • For Linux or macOS, select the equivalent sensor separately and test its emitted fields; a Windows event ID does not transfer across platforms.

Required normalized fields: process_id, path, action, size_bytes.

}

Visibility limits: Event filtering and sensor versions change coverage. High-volume image-load and process-access collection needs tuning; endpoint events alone do not establish intent.

Protected Configuration · source-mapped

DC0115 collection page — Use approved device-management/research-build interfaces to snapshot the specific protected setting; document privileges and unsupported fields.

Providers and collection configuration

  • Android logcat: Permitted logs from a consented test device/emulator; output depends on build, permissions and instrumentation.

Detection rules and analytic guidance

DET0657 Detection of Subvert Trust Controls

MITRE detection strategy

AN1745 Analytic 1745

For Android, detect Subvert Trust Controls 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]; File Creation via Application Vetting / Forensic Acquisition [Dynamic filesystem trace or acquired app-container/filesystem artifacts: PackageInstaller.install() with installer_source NOT IN $ApprovedInstallSources$ within $PolicyViolationWindow$ of settings change]; 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.

Platforms: Android.

  • Application Permission — android:DevicePolicyManager; channel DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review.
  • File Creation — mobile:ForensicArtifacts; channel Dynamic filesystem trace or acquired app-container/filesystem artifacts: PackageInstaller.install() with installer_source NOT IN $ApprovedInstallSources$ within $PolicyViolationWindow$ of settings change.
  • System Settings — android:DevicePolicyManager; channel DevicePolicyManager policy/compliance/security-state queries and SecurityLog events where supported.

AN1746 Analytic 1746

For iOS, detect Subvert Trust Controls 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]; File Creation via Application Vetting / Forensic Acquisition [Dynamic filesystem trace or acquired app-container/filesystem artifacts: app binary written to device with signing certificate matching manually-trusted enterprise cert NOT IN $EnterpriseCertAllowList$ within $ProfileInstallWindow$]; Protected Configuration 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.

Platforms: iOS.

  • Application Permission — mobile:ApplicationVetting; channel Code-signing entitlements and Info.plist privacy usage-description keys.
  • File Creation — mobile:ForensicArtifacts; channel Dynamic filesystem trace or acquired app-container/filesystem artifacts: app binary written to device with signing certificate matching manually-trusted enterprise cert NOT IN $EnterpriseCertAllowList$ within $ProfileInstallWindow$.
  • Protected Configuration — iOS:MDM; channel DeviceInformation / SecurityInfo / ProfileList / restrictions and compliance queries.
Source rule directory and observation requirements

No exact-tagged Sigma source rule was imported. This does not establish that the technique is undetectable; the MITRE guidance and collection requirements remain relevant.

Before treating a rule as coverage

  1. Read the actual condition and logsource; identify attacker-side, victim-side or third-party visibility.
  2. Map native sensor fields, parse times and identities, then compile for the selected backend.
  3. Replay a behavior-positive case, a normal control, an authorized look-alike and a missing-telemetry case.
  4. Record matches and misses with rule version and source events. No match is inconclusive when required telemetry is absent.

Anomaly-based detection

No exact technique-specific Atlas model is present for T1632 in the selected source snapshot. The following is a design worksheet, not a newly validated model.

Anomaly engineering worksheet

Start from the exact analytic above. The collection-specific lenses below are analyst recommendations; they do not assert that an arbitrary statistical deviation detects this technique.

  • Mobile lab instrumentation: Per owned device, app version and permission state: unexpected API/permission changes, background activity and network destinations. OS privacy restrictions and emulator differences limit observability.
  • Endpoint activity: Per host role and user: rare process/object combinations, bursts of object access or modification, and ordered parent/action sequences. Compare maintenance windows and signed software rollout activity.
  1. Define an entity/peer group and feature; exclude the evaluation period from baseline training.
  2. Use representative normal and maintenance activity. Do not invent a production threshold from a synthetic example.
  3. Evaluate held-out behavior-positive and benign cases; measure false positives, misses and telemetry loss separately.
  4. Keep abnormality separate from maliciousness. Correlate with the behavior-specific source evidence.

Attack tools and documented software

No reviewed lab-tool association is selected for this exact technique. This is a curation gap, not a statement that no tool can implement the behavior.

Simulation design and documented procedures

Atomic evidence: no compatible candidate in this snapshot. Live lab status: not run for these imported procedures.

Use owned test devices or emulators, disposable app accounts and test data. Verify platform/version instrumentation; desktop test procedures do not establish mobile coverage.

No compatible Atomic procedure is present in this pinned evidence set. Technical feasibility has not been ruled out. A custom procedure must define the behavior, target, collection point, success observable and rollback before execution.

Technique-specific experiment contract

  1. Choose one procedure implementing T1632 Subvert Trust Controls; identify the observable behavior in the source definition, not just its tactic.
  2. Record exact target, tool/version, inputs, privileges, network limits and approval. Never run an imported default target automatically.
  3. Enable the collection sources above and verify a benign baseline reaches the detector.
  4. Run only the approved isolated scenario; capture native events and an independent behavior observable.
  5. Evaluate the exact rule/model, restore the lab, and preserve configuration, event hashes, alerts, controls and misses.

Source-linked mitigations
  • M1006 Use Recent OS Version

    Mobile OSes have implemented measures to make it more difficult to trick users into installing untrusted certificates and configurations. iOS 10.3 and higher add an additional step for users to install new trusted CA certificates and configuration profiles. On Android, apps that target compatibility with Android 7 and higher (API Level 24) default to only trusting CA certificates that are bundled with the operating system, not CA certificates that are added by the user or administrator, hence decreasing their susceptibility to successful adversary-in-the-middle attack.[Symantec-iOSProfile2][Android-TrustedCA]

  • M1011 User Guidance

    Typically, insecure or malicious configuration settings are not installed without the user's consent. Users should be advised not to install unexpected configuration settings (CA certificates, iOS Configuration Profiles, Mobile Device Management server provisioning).

  • M1012 Enterprise Policy

    On iOS, the `allowEnterpriseAppTrust` and `allowEnterpriseAppTrustModification` configuration profile restrictions can be used to prevent users from installing apps signed using enterprise distribution keys.
