Dallas, Texas officials are still attempting to figure out who hacked into the city's emergency warning system Friday night, setting off all 156 sirens across the city and inundating the 911 center with calls from concerned residents. The warning system, which alert residents to severe weather or other public emergencies, was likely breached by someone within close proximity to the Dallas area according to city spokeswoman Sana Syed. Budding Sherlock and Mayor Mike Rawlings said this was "evidence of a need to upgrade and safeguard the city's technology infrastructure", since this obviously wasn't being done before.
The attacker was able to turn the sirens back on 15 times in a 90 minute period, thwarting technicians trying to stop them. City officials were forced to contact the Federal Communications Commission for assistance when it became obvious they were unable to prevent the hackers from rearming the system again once shut off, and were hopeful the system would be restored to "normal operations" again by the end of the weekend, likely meaning returning it to its former state and hoping no one breaks it again.
