Ken Pyle, the cybersecurity researcher who found out the problem, advised CNN that he got a number of of the EAS units independently and located deficient safety controls.

Seeing the breakdown of legislation enforcement communications within the days earlier than the January 6, 2021, assault on the United States Capitol motivated Pyle to dig additional into the protection of the ones varieties of communications, he stated.
“It is a large essential infrastructure downside everybody must personal,” stated Pyle, who’s a spouse at safety company CYBIR. He’s going to show his analysis subsequent week in Las Vegas at DEF CON, one of the crucial global’s greatest hacking meetings.
The misuse of emergency indicators can create panic.
