“For security reasons, we cannot discuss the details of how this was done, but we do believe that the hack came from the Dallas area. We have notified the FCC for assistance in identifying the source of this hack. We are putting in safeguards to ensure this type of hack does not happen again,” the city said in a news release.

All of the city’s 156 emergency alert sirens started being triggered at 11:42 p.m Friday night, continuing into early Saturday morning. Dallas City Fire and Rescue had to visit each individual siren site and manually shut down the systems.

City officials said that Dallas 911 received over 800 calls during a fifteen minute period around midnight.

Dallas Mayor Mike Rawlings described the incident as “an attack on our emergency notification system.” Mayor Rawlings posted on his Facebook page about the need for a better security infrastructure.

“This is yet another serious example of the need for us to upgrade and better safeguard our city’s technology infrastructure. It’s a costly proposition, which is why every dollar of taxpayer money must be spent with critical needs such as this in mind. Making the necessary improvements is imperative for the safety of our citizens,” Mayor Rawlings said.

    This has me thinking that if a hacker/hackers can do this, what can’t they take over and use/misuse. Imagine our electrical grid, sanatation, water, ATMs getting hacked in a large city/cities. Preparing to be off grid as much as possible with preps seems a better idea as time goes by. Nothing ran on line appears to be safe even with security. Hell government data bases have been hacked along with top tier financial data. The more we depend on computers the more likely our infrastructure and personal data is at risk!

      Best for all to take note and add extra preps.
