Research tool for analyzing VPN detection mechanisms on Android.
- Detect VPN via NetworkCapabilities.TRANSPORT_VPN
- Analyze active vs global VPN state
- Interface detection (tun0, wg0)
- Native + Java network enumeration
Demonstrates how apps can detect VPN presence even with split tunneling.
android.permission.ACCESS_NETWORK_STATE— used to access network state viaConnectivityManagerandroid.permission.QUERY_ALL_PACKAGES— used to enumerate installed applications in order to detect known VPN clients
VPN Active (full tunnel)
VPN Split / Bypass (still detectable)
