Council member wants update on Dallas siren hacking

Hacking Dallas' sirens: What we know now

A little more than 48 hours after the city of Dallas heard the most audible indication of its emergency system fragility, council members are requesting more information ahead of a Monday hearing.

District 14 council member Phil Kingston told News 8 on Sunday he has asked the Dallas city attorney's office to invoke an emergency provision that would allow the known details of the hack to be part of a briefing to the Public Safety Committee on Monday.

Under Texas open meetings law, a topic for discussion must be posted to the public with 72 hours advance notice.

Kingston said he hopes the committee can receive a briefing, even if the 5-member committee is unable to ask questions.

"If it is as bad a problem as it sounds like it could be, then it's something the council needs to move on immediately," Kingston said. “We want a briefing. This needs to move to the top of the list because if it is hacking its absolutely terrifying.”

Rocky Vaz, director of Dallas' Office of Emergency Management said on Saturday an unknown person from outside the city of Dallas system was able to send multiple signals to the city's 156 outdoor sirens.

The sirens were activated multiple times in a 90-minute period beginning at 11:42 p.m. on Friday and lasting until about 1:15 a.m.

"We know how they did it so we can stop that from happening again," Vaz said.
