Slovakia bought speed trap cameras. Its security authority found a Russian-linked backdoor.

A technical review of a NERO R-ONE speed camera found an undocumented mechanism that could grant shell access via SMS from hardcoded Russian phone numbers. The authority also found disabled SecureBoot, an unauthenticated web-management portal, and exposed live video feeds. It assessed the device as a rebranded Russian CORDON PRO.M.

The lesson: Verify and regularly re-confirm everything that is connected to your networks. Even something mundane as an inexpensive and convenient "smart" coffee machine could end up being a easy way in for bad actors. 

A networked camera is a computer with sensors. Treat it like one.
