The airline said the event did not affect flight safety and that none of its operational systems were compromised, Yahoo! reported.The incident occurred aboard Delta Flight 591 on Aug. 10 while the Boeing 757 was en route from Las Vegas to Atlanta. According to the airline, an initial review found that the network was not created, operated or supplied by Delta. Flight attendants shut down the aircraft’s Wi-Fi service for roughly 30 minutes while the situation was assessed, fox5atlanta.com said.Delta said its investigation found no evidence that the airline’s systems were breached. The carrier emphasized that aircraft operating systems were unaffected and that the safety of the flight was never at risk. The flight continued to its destination without declaring an emergency. Authorities are now reviewing the incident alongside the airline. Delta said it plans to work with federal law enforcement agencies and aviation regulators to determine exactly what happened and whether any passengers were targeted. The Federal Aviation Administration has acknowledged the report and said that in-flight internet systems are separate from critical flight controls. Reports circulating online claimed the unauthorized network appeared under a name resembling Delta’s official onboard internet service. Messages attributed to flight crew members suggested concern that the network may have been intended to trick travelers into connecting to a fraudulent access point. Delta has not publicly identified who created the network and says its investigation remains ongoing. The episode attracted additional attention because it occurred shortly after DEF CON, one of the world’s largest cybersecurity conferences, concluded in Las Vegas. While some reports noted that conference attendees were among the passengers, investigators have not publicly connected any individual to the unauthorized network. Travel experts say unauthorized wireless networks on commercial aircraft are uncommon but can create confusion for passengers. Security specialists generally recommend that travelers connect only to the network identified by the airline and verify network names before entering any personal information or login credentials. Despite the disruption, Delta said the flight landed safely in Atlanta and thanked both crew members and passengers for their cooperation. The airline has not said whether any traveler information was compromised and continues to gather additional facts about the incident.
