DET0641 Detection of Encrypted Channel
AN1716 Analytic 1716
An application performs explicit cryptographic operations (e.g., symmetric/asymmetric encryption routines) on locally collected or generated data, followed by structured outbound network communication that does not align with expected application behavior, particularly when occurring in the background or without user interaction. Detection correlates crypto API usage + data staging + application state + network transmission patterns.
AN1717 Analytic 1717
Indirect evidence of application-layer encrypted channel usage inferred through anomalous background processing and network transmission patterns following application activity, where encryption operations are not directly observable. Detection correlates background execution + network behavior + application entitlement posture to identify misuse of encrypted communication channels.
