[EAS] Dallas warning sirens hacked - maybe

[Ed Czarnecki]

The city is sticking to the story that it was a hacker (whether or not test
mode was involved), and also infer that it was someone "in the Dallas area".
In this case, the scenario involves a large 150+ siren system is managed by
three control points (two in the same building), all of which set up to
allow remote activation via the Internet ...  Which is the interesting part
- these may have been attacked individually, or at a central control point.
But the central control points apparently could not shut they sirens down
once activated.
