Recently there has been an incident in Dallas where the residents were awakened on Friday night by 156 emergency sirens that suddenly wailed throughout the city. According to the police officials, the sirens were set off by a group of hackers.
Rocky Vaz, the head of city’s Office of Emergency Management said at a news conference that the person or group responsible were able to hack into the part of the system that was communicating with the city’s sirens. All the sirens were successfully deactivated within 1:20 AM. The officials said, “We shut it down as quickly as we could, taking into consideration all of the precautions and protocols we had to take to make sure that we were not compromising our 156 siren system.” The officials suspect that the hack was done from somewhere within the Dallas area. The FCC was notified immediately to assist in identifying the source of the hack and the city is also working to put safeguards to prevent this type of attacks again. City officials say that the priority is working to reactive the siren system and work will be done through the weekend. Residents are asked to be patient and to avoid calling 911 as the sirens might sound again during the process of reactivation.
