I tried to use the AF B789 WiFi a few days ago and when it tried to access payment.klm.com my browser gave all sorts of security warnings and would not even let me go to that site. So I opened up a packet decoder and it seems that there was either a hacker on board my flight, or someone had installed their own AP on the plane. There were TLS handshake failures and the vendor code for the airplane Access Point was Matsushi!!
