T1663 Remote Access Software — Attack Simulation

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.

  "schema": "1200km.telemetry.example.v1",
  "synthetic": true,

    "permission": "android.permission.CAMERA",
    "declared": true,

  }
}

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.

DC0082 collection page — Enable scoped Sysmon NetworkConnect (3), disabled by default, or a platform-equivalent process-aware network sensor.

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_guid, destination_ip, destination_port, protocol, initiated.

  }
}

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.

DC0078 collection page — Collect Zeek conn.log, Suricata flow events or exporter equivalents, including observation point and sampling settings.

Providers and collection configuration

• Zeek: Connection and protocol metadata from traffic visible to the sensor.
• Suricata EVE: Configured flow, alert, DNS, HTTP, TLS and protocol records.
• AWS VPC Flow Logs: IP traffic metadata alternative; no packet payload or DNS answer history, and some traffic is not logged.

• Use an authorized lab TAP/SPAN, virtual mirror or gateway interface. Define which traffic crosses it; avoid assuming visibility into every segment.
• Enable the required Zeek analyzers or Suricata EVE event types. Export logs with sensor identity, clock synchronization and flow correlation identifiers.
• Monitor capture loss, truncation and exporter sampling. Capture payload only with approval and restrictive retention; encryption normally prevents plaintext inspection.

Required normalized fields: source_ip, destination_ip, destination_port, protocol, bytes_sent, bytes_received.

    "bytes_sent": 128,
    "bytes_received": 512
  }
}

Visibility limits: Flows are not packet payloads. NAT, asymmetric routes, encryption, missing mirrors and sampling can hide attribution or content. A destination connection alone does not prove malicious intent.

MITRE detection strategy

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.

• M1011 User Guidance

  Users should be encouraged to be very careful with granting dangerous permissions, such as device administrator or access to device accessibility.

• M1012 Enterprise Policy

  When devices are enrolled in an EMM/MDM using device owner (iOS) or fully managed (Android) mode, the EMM/MDM can collect a list of installed applications on the device. An administrator can then act on, for example blocking, specific remote access applications from being installed on managed devices.
