Detection of Steganography

For Android, detect Steganography by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate File Creation via Application Vetting / Forensic Acquisition [Dynamic filesystem trace or acquired app-container/filesystem artifacts: open() with O_CREAT on binary-typed path in /data/data// within $StegoExecWindow$ of media file download from same session]; Module Load via Application Vetting / Instrumented Dynamic Analysis [Dynamic API/runtime trace: DexClassLoader() or dlopen() on path written within $StegoExecWindow$ of media download event — download-write-load chain confirms steganographic payload delivery]; Network Connection Creation via Android Enterprise Network Logging / Enterprise VPN [DevicePolicyManager.retrieveNetworkLogs(): DnsEvent / ConnectEvent; VPN flow metadata]. 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.
