[PPRAANet] Dallas Emergency Siren System Hacked Via Radio!

[Phillip H. Blanton]

For those of you with a hacker heart...

According to astatement 
<http://www.dallasobserver.com/news/dallas-siren-hack-done-by-radio-not-computer-9358087>issued 
on Monday, Dallas City Manager T.C. Broadnax clarified the cause of the 
last Friday's chaos, saying the "hack" used a radio signal that spoofed 
the system used to control the siren network centrally.

"/it's a tonal-type system/" that's usually controlled by tone 
combinations used by the EAS broadcast over the National Weather 
Service's weather radio, and by Dual-Tone Multi-Frequency (DTMF) or 
Audio Frequency Shift Keying (AFSK) encoded commands from a command 
center terminal sent over an emergency radio frequency.

Apparently unencrypted.
