■ AI-SUMMARIZED FROM 1 SOURCE ▸ TIMELINE

Delta Air Lines is investigating an unauthorized Wi-Fi network that appeared aboard a flight from Las Vegas to Atlanta carrying DEF CON attendees. The incident suggests a possible deauthentication attack targeting passengers.

The rogue network emerged during a flight with passengers returning from DEF CON, an annual hacker convention held in Las Vegas. A deauthentication attack—a technique that disconnects devices from legitimate networks—may have been used to create the unauthorized access point. Deauth attacks work by broadcasting forged wireless frames that force connected devices offline, allowing attackers to intercept traffic or redirect users to malicious networks. The targeting of DEF CON attendees, who typically include security researchers and cybersecurity professionals, suggests either a demonstration of the vulnerability or an opportunistic test. Delta stated it is reviewing the incident and coordinating with relevant authorities. The airline did not confirm the attack's success or whether any passenger data was compromised. Airlines have increasingly faced scrutiny over onboard Wi-Fi security, with previous incidents demonstrating vulnerabilities in aircraft connectivity systems. DEF CON organizers did not immediately respond for comment on the incident.
