Dallas looking at why emergency sirens sounded in error

Dallas residents were jolted out of bed late Friday evening after a hacker triggered all the city's emergency sirens, setting off a wave of panic and confusion. "For security reasons, we can not discuss the details of how this was done, but we do believe that the hack came from the Dallas area". Officials say all of the city's 156 outdoor sirens that are used to alert people to shelter indoors during severe weather.

Dallas City Fire and Rescue had to visit each individual siren site to manually turn them off. As officials are booting the system back up, emergency alarms may sound off again; officials urge residents not to call 911 reporting the sirens during that time. "We will work to identify and prosecute". The city's Office of Emergency Management says there is no emergency and they are asking people not to call 911. In the meantime, the public has access to other alert systems, including reverse 911. The city says they're trying to determine what caused the malfunction.

When it finally happens, the end of the world will likely begin like this: with wailing sirens tearing through the night sky sending chills down your spine as you contemplate if you've lived a good and meaningful life. The initial incident prompted a wave of calls to 911 by residents anxious there was some sort of threat.

Dallas Mayor Mike Rawlings described the incident as "an attack on our emergency notification system".

"This is yet another serious example of the need for us to upgrade and better safeguard our city's technology infrastructure".
