At the virtual conference IEEE International Conference on Communications (ICC) 2021 Christian Burkert is presenting the paper “Analysing Leakage during VPN Establishment in Public Wi-Fi Networks” today.
Christian Burkert and co-authors Johanna Ansohn McDougall, Hannes Federrath and Mathias Fischer have analysed how personal VPN apps on different operating systems (iOS, Andoid, Windows, …) behave when operated in an open Wi-Fi hotspot with a captive portal. The analyses found serious problems with almost all apps. Either deadlocks occur, which prevent a VPN setup and thus secure surfing, or there is even unintentional disclosure of data traffic.
