cherepavel/VPN-Detector

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 via ConnectivityManager
• android.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)
