That's right -- we're living in the age where not even our calls to 911 are kept secure.
The 911 system of Baltimore was breached on the 25th of March.
Baltimor city personnel detected the intrusion at 08:30 local time on the 25th of March. They quickly determined that unknown attackers had hacked into the municipality’s computer-aided dispatch (CAD) system.
This type of network is responsible for displaying 911 callers’ location data on mapping systems, streamlining the process of connecting callers with the closest emergency responders and sometimes logging information for records.
As such, bad actors can abuse it to potentially steal some medical information and access mapping systems, assets which Baltimore and other cities need in the event of a city-wide emergency.
Upon detection of the incident, employees of the city temporarily transitioned the 911 system into manual mode.
The CAD system was offline for a total of 17 hours. During that time, Baltimore personnel identified the affected server and disconnected it from the city network, thereby remediating the breach. They then fully restored the system at around 02:00 on 26 March.
