DEF CON crowd suspected in fake-hotspot attack on Delta flight

Federal authorities are examining reports of an unauthorized wireless network created aboard Delta Flight 591 traveling from Las Vegas to Atlanta on Monday. The incident allegedly involved passengers who had attended the DEF CON security conference, which concluded the day before the flight departed.

According to accounts tracking aircraft communications, pilots reported that conference attendees created a spoofed Wi-Fi network and broadcast unauthorized signals. The fake network, identified as “Delta WiFi Fast,” reportedly included a phishing landing page designed to capture passenger login credentials and personal information. This technique, referred to as an “evil twin” attack in cybersecurity contexts, has long been documented as a method for intercepting user data through fraudulent wireless networks.

Delta Air Lines confirmed the presence of an unauthorized Wi-Fi network aboard the aircraft for a brief period during the flight. A company spokesperson stated that the airline’s legitimate onboard Wi-Fi service was temporarily disabled for 30 minutes as a result. The airline emphasized that aircraft safety systems and operational systems were not affected and that no emergency was declared.

The FBI’s Atlanta field office confirmed it is investigating the matter in coordination with local and corporate partners. The agency stated that no arrests have been made and agents did not intercept passengers upon arrival. The Atlanta Police Department directed inquiries regarding the incident to federal authorities, who indicated they had no additional information available at the time.
