For Android, detect Proxy Through Victim by correlating analyst-visible device/network evidence and management state; use streaming or batched telemetry only where the documented collector is deployed. Correlate Application Permission via Android Enterprise DPC / Application Vetting [DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review]; Network Traffic Content via Enterprise Secure Web Gateway / Proxy [DNS/HTTP(S) inspection or proxy transaction metadata where enterprise decryption/inspection is deployed]; Network Traffic Flow 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.
| Data Component | Name | Channel |
|---|---|---|
| Application Permission (DC0114) | android:DevicePolicyManager | DevicePolicyManager.getPermissionGrantState(); PackageManager manifest/requested-permission review |
| Network Traffic Content (DC0085) | webproxy:applog | DNS/HTTP(S) inspection or proxy transaction metadata where enterprise decryption/inspection is deployed |
| Network Traffic Flow (DC0078) | android:EnterpriseNetworkLog | DevicePolicyManager.retrieveNetworkLogs(): DnsEvent / ConnectEvent; VPN flow metadata |
| OS API Execution (DC0021) | mobile:DynamicAnalysis | Dynamic API/runtime trace: App initializes proxy-capable or raw-socket networking constructs (ServerSocket, SOCKS proxy client, bidirectional relay) NOT IN $ApprovedProxyApps$ — proxy initialization is the technique enabler |
| Field | Description |
|---|---|
| ApprovedProxyApps | VPN client, enterprise proxy agent, MDM agent with tunnel capability. Derive from MDM catalog. Tightening: only MDM-provisioned VPN apps. |
| RelayWindow | Default 5s between inbound session and outbound relay connection. Proxy relay is near-synchronous. Tightening: 2s. |
| FanOutThreshold | Default 3 distinct outbound destinations per inbound session. Single-destination relay may be VPN; multi-destination fan-out is proxy. |
