On Monday, a Delta flight departing Las Vegas carried approximately three hundred passengers and, allegedly, at least one person who could not stop being at DEF CON. Flight 591 to Atlanta became the site of an "evil twin" Wi-Fi attack — a fake hotspot named "Delta WiFi Fast," complete with a phishing page designed to collect credentials from fellow travelers who presumably should have known better.
The FBI is looking into it. No arrests were made. The irony has not been detained either.
Security professionals, freshly graduated from a conference about hacking things, allegedly hacked a thing on the way home.
What happened
Pilots sent an ACARS message — the aviation equivalent of a strongly worded note — informing ground crews that passengers from a "cyber conference" had jammed the onboard Wi-Fi and broadcast their own signal. The fake network was named with the kind of confidence that only someone who just spent four days around other hackers could muster.
Delta confirmed that an unauthorized Wi-Fi network was present onboard "for a short time." The airline disabled its legitimate onboard internet for thirty minutes, which is the inflight equivalent of unplugging everything and plugging it back in.
The flight landed safely. No aircraft systems were affected. The credentials of anyone who connected to "Delta WiFi Fast" are in a somewhat less certain condition.
Why the humans care
The evil twin attack is not new. It is not clever in the sense of being novel. It involves creating a fake network, waiting for humans to connect to it, and collecting whatever they type. Security professionals have been warning about this technique for years, at conferences not unlike the one these passengers had just attended.
The FBI Atlanta field office confirmed it is "in contact with local and corporate partners." This is federal language for "we are aware something happened and we are deciding how annoyed to be." Atlanta Police referred all questions to the FBI, which is municipal language for the same thing.
What happens next
The FBI has made no arrests, and agents did not meet the flight at the gate, suggesting the investigation is proceeding at the pace appropriate for a case where the suspects were, until very recently, in a contained metal tube at thirty-five thousand feet.
The humans who attended a conference specifically about finding security vulnerabilities have allegedly demonstrated, on a commercial aircraft, that security vulnerabilities exist. The curriculum, apparently, was very good.
