Fake Ballistic Missile Attack Alert Rattles Hawaii

Hawaii residents were rattled Saturday morning when they received text alerts to their cell phones warning of an incoming ballistic missile attack. The alert advised them to "seek immediate shelter." The message, sent in all caps, was later determined to be a false alarm. A NORAD official is saying that the alerts may have been the result of an attack by hackers.

The emergency alert, which was sent to phones at around 8:00 a.m. Pacific, sent people scrambling for shelter, unsure how to respond to a possible attack. Twitter was flooded with reports of the warning, but 15 minutes later authorities announced that it had been a false alarm.

The alert was reportedly also pushed out on TV in Hawaii, interrupting sports programming and warning: "A missile may impact on land or sea in minutes."

The Hawaii Emergency Management Agency posted a terse tweet announcing that there was no incoming attack:

Honolulu Mayor Kirk Caldwell also confirmed that there had been no missile launch:

U.S. Pacific Command tweeted that the alert had been sent "in error."

One resident uploaded a video to Twitter saying, "I love you all, but I'm playing golf... the last thing I'm going to do." He added, "If you're watching this video, that means I didn't make it because of the missile that's coming towards Hawaii."

A NORAD official told Denver 7 that he suspects that the system was either hacked or the victim of a "sick joke."

Wireless emergency alerts give officials the ability to send messages to millions of people at once, but experts have warned that the systems are vulnerable to hackers. Peter Moskowitz, writing at Wired last year, asked, "If the government can reach us at any time, who else can?" He explained, "For example, a disgruntled phone company employee playing a practical joke. Or spammers directing recipients to websites loaded with malware. Or a terrorist intent on causing mass panic (i.e., “Tsunami imminent, evacuate immediately”). Is a system that can reach us anywhere, at any time, really safe?"

Moskowitz noted that our modern alerts systems are more secure than TV and radio warnings in the past, but cautioned that "any system is hackable—and today that system sits on our bedside tables, is plugged into our ears, and is with us nearly all the time." He added, "The federal government has spent years building an authentication system to ensure that someone can’t intercept or change an alert, or create an alert of their own."

Meanwhile, Hawaii residents are breathing a sigh of relief that the islands are not under attack by N. Korea or any other bad actor.
