What happened
A passenger on a Delta flight from Las Vegas to Atlanta after DEF CON is suspected of jamming the aircraft's in-flight Wi-Fi and broadcasting a fake network called 'Delta Wifi Fast,' possibly using a deauthentication attack and a device like a Wi-Fi Pineapple to phish passenger credentials. Delta confirmed the incident, stated no aircraft systems were affected, and said it is investigating with federal law enforcement.
Why it matters
This is a cautionary incident about how trivially captive-portal Wi-Fi can be spoofed with off-the-shelf tools, but it does not require any change to what builders ship. If you build apps that handle authentication over public or shared Wi-Fi, treat untrusted network captive portals as hostile and never rely on network-level trust for credential entry.
Discussion angle
A quick reminder on why captive-portal Wi-Fi is inherently untrusted and what deauth attacks look like in practice, without overstating the relevance to most builders' day-to-day work.
