Hackers wake up Dallas with tornado sirens
The hack switched on tornado alarms in Dallas on Friday night.

Hackers set off tornado warning sirens in Dallas in the US at the weekend, waking residents on Friday night.

All 156 warning sirens in the city were switched on at around 23:45 on Friday, and city authorities were not able to switch off all sirens until they deactivated the whole system an hour and a half later.

Dallas City Hall said that it could not reveal the nature of the hack, but that it believed it originated within the city area. As of Saturday 8th, the city was not able to tell if the siren network had been damaged by the hack.

City Hall also said that it is seeking assistance with the Federal Communications Commission (FCC) to identify the nature of the attack and prevent it from happening again.

The siren network is usually deployed to warn the 1.3m residents of Dallas of severe weather events, such as tornadoes.
