if there is a system that decodes light signals into something then likely the decoder could be popped. I've wondered this about radio signals, because airgapped and interesting netwotks listen to radio but generally do not have optical listeners...

if you look at cameras, what is being done with the signal.

people already thwart image recognition using weird patterns. in a way that is hacking using light..

thus any visual reasoning system is currently being attacked using light as that is what it perceives.

Threat modeling exercise for educational and discussion purposes only.

You would need to understand the exploit chain needed within an ALPR to determine where a potential weakness would be possible, from camera CCD to the onboard code engine that processes the imagery and ships back to the control plane over a mobile provider network. Not impossible, but not easy, easiest way would be to have an LLM de-compile and search the ALPR's code contents, if one had access to one. This would also help you understand if there was an exploit path into the control plane based on the interface details between the ALPR network and the control plane.
