All municipal infrastructure tends to be. It's usually implemented to a cost and security considerations are completely absent.
You can bet that in any given city, all those street light control cabinets are keyed alike and the city has no true idea who has keys and who doesn't.
This exact problem applies to so many domains it's literally for lack of effort that they haven't been exploited yet.
- distant_hat 7y agoIn India I found that in Bangalore (a city with far better infrastructure than most other), for a lot of intersections the traffic lights are toggle switches that some cop flicks on and off every so often. There is no lock on the switch cabinet.
- dotancohen 7y agoAll those cabinets use the same key across cities as well! Otherwise FEMA and other services would be unable to function. For the same reason all LEO handcuffs use the same key, so that any officer could release any handcuffed individual.
