‘SirenJack’ Vulnerability Lets Hackers Hijack Emergency Warning System

The sound of an emergency alert siren can be a nightmare soundtrack to the millions who live in areas subject to hurricanes, tornados, earthquakes, or other natural disasters. A recently disclosed vulnerability in the emergency warning system used by San Francisco and other municipalities could allow a threat actor to take control of the system, sound false alarms, or block legitimate warnings.

While the vendor – ATI – says it has now patched the so-called SirenJack vulnerability, an unencrypted protocol, the process of its discovery could have implications for other locations.
