Delta investigates in-flight Wi-Fi spoofing on post-DEF CON flight from Las Vegas

Delta is investigating reports that a passenger on flight 591 from Las Vegas to Atlanta set up a rogue Wi‑Fi access point named "Delta WiFi Fast," an "evil twin" style hotspot that could be used to capture unencrypted traffic or harvest credentials. Cabin crew disabled the aircraft Wi‑Fi for about 30 minutes, the flight was delayed, and the FBI and FAA are aware; Delta reports no impact to aircraft systems and no confirmed data theft while the investigation continues.
