Not so silent night: Dallas emergency siren system hacked
DALLAS (AP) — Hackers struck the sirens Dallas uses to alert residents to take shelter from inclement weather, triggering intermittent false alarms for about an hour and a half until officials deactivated the system early Saturday morning.
The person or people responsible were able to hack into a part of the system that was communicating with all 156 of the city's sirens, Rocky Vaz, who heads the city's Office of Emergency Management, said at a news conference.
Technicians were trying to determine how to bring the system back online without the risk of it being hacked again, he said.
[...] the public has access to other alert systems.
