This is very concerning:

We learned last week that a group of hackers gained access to cameras installed by a surveillance camera company, and said they were able to access live feeds from 150,000 cameras inside schools, hospitals, gyms, police stations, prisons, offices, and women’s health clinics. Some of the video footage — showing patients in their hospital rooms, for example — was extremely privacy-violating.

The company, Verkada, does not merely sell security cameras; it also provides a variety of surveillance services to its clients, including cloud storage of video footage and remote access to camera feeds on smartphones or other devices. Because the company streams video to a centralized source (its servers) to provide these services, the hackers were able to access not just a few cameras here and there, but a vast number of video feeds.

What does this breach tell us about the state of security today? While the story has many dimensions, it offers four principal reminders about surveillance, video, and internet-connected devices.
