In Wake of Siren Hack, Cybersecurity Expert Calls For Vigilance

D Magazine | April 25, 2017

Armor’s Jeff Schilling talks to D Magazine about the siren system that simultaneously set off over 150 towers. “The way things work is similar to a pager,” he said, adding that the sirens are connected by a radio frequency from one or multiple towers. “Each of the individual towers have a code and they’re activated when they receive an individual radio prompt. I have a theory that whoever pulled this off has to have pretty intimate knowledge of how it works and the vulnerabilities.”
