DET0718 Detection of Ingress Tool Transfer

AN1848 Analytic 1848

The defender correlates an application establishing outbound retrieval to a non-baselined external source with immediate local creation of a new executable, module, staged payload, overlay asset, or secondary file in app-controlled or shared storage, followed by optional load, invocation, handoff, or repeat retrieval behavior. The analytic prioritizes Android-observable effects: network download activity, DownloadManager or direct HTTP retrieval, file creation in package-specific or external paths, and execution context inconsistent with recent user interaction or the app’s declared role.

AN1849 Analytic 1849

The defender correlates managed-app network retrieval from a non-baselined external source with immediate creation of a new local artifact, staged resource, module-like file, or opaque payload inside the app container, followed by optional dynamic loading, handoff, or repeat retrieval behavior. Because iOS offers weaker direct visibility into tool staging internals than Android in many environments, the analytic anchors first on network acquisition plus managed app identity and then strengthens confidence with file creation or process-activity effects where mobile telemetry is available.
