By the time the president had rolled into town and his press secretary and staff had finished arranging things and the media had set up their equipment, the day was in its last hour. Which might have been calculated, since the light was magical, and lit up the red rocks east of town perfectly while making everyone seem ten years younger and twice as good-looking. They found a place where the president could look into that light, with mountains and a big sign that said MOAB in the background of the shot. They set up the presidential lectern and handpicked people to stand to the left, and to the right, and behind it: uniformed National Guardsmen; Native Americans; salt-of-the-earth farmers; outdoorsy types with frizzy, sun-bleached hair; a minister; and an Asian-American tech executive with a disabled girlfriend. The president came online and announced to the world that Moab, the states of Utah and Colorado, the United States of America, and indeed the entire world had been the victims of a hoax that had been perpetrated almost entirely on the Internet. Nothing had happened here, save for a denial-of-service attack, originating overseas, that had shut down its Internet service and its cell phone towers. There had never been a bright flash of light; this was just a pattern of fake social media posts. The young actor at LAX was just that—a performer who had been hired to play a role, under the pretext that it was some kind of reality television show. Local police departments had been conned into setting up roadblocks by telephone calls that had originated overseas but been digitally tweaked to look as if they were local. A similar call had summoned the SWAT team in Las Vegas. They’d found nothing more than an empty suite that had been booked and paid for online. No one had ever checked in, but a package had arrived from overseas and been delivered to the suite by hotel staff. It turned out to be some old radium-dial watches in a scary-looking box: enough to make the cops’ Geiger counters click but not in any way dangerous. A similar gambit had been used in Manhattan. All of the confirmatory posts that had hit the Internet in the next hours—the burn victims, the fallout samples, the Los Alamos press conference—had been faked and injected onto the Internet via social media accounts and domains controlled through untraceable overseas shell companies.
