DET0628 Detection of Supply Chain Compromise

AN1697 Analytic 1697

An app or app update arrives through an expected delivery path or presents as a known legitimate package identity, but its post-install or post-update behavior materially changes in ways inconsistent with its historical role. The defender correlates package identity and install/update context, newly expanded capability state, changed runtime framework use, new sensor or storage behaviors, and new network destinations shortly after installation or update to identify likely supply-chain compromise rather than ordinary malicious sideloading or unrelated post-compromise activity.

AN1698 Analytic 1698

A managed or supervised app, app update, or enterprise-distributed build retains a legitimate-seeming identity but exhibits post-delivery behavior inconsistent with its expected role, prior version, or distribution context. Because iOS exposes less direct visibility into bundled dependency tampering or component-level supply-chain insertion, the defender prioritizes supervised app inventory, signing/provisioning trust posture, entitlement and behavior drift after update, new sensor/resource use, and new downstream network effects soon after install or version change.
