You sure the door lock companies are hiring the best and brightest engineers? Not clear to me an LLM is not attractive in that scenario.
It’s who else has access: property and facility management, maintenance, etc. In the age of physical keys, I trusted these SMBs to be relatively capable, let’s say 7/10, in protecting those keys from most local would-be criminals and opportunists. That goes down to 2/10 for protecting digital assets, like remote unlock capabilities, from cybercrime.
As soon as there is a viable market connecting cybercriminals with local criminals, whether it’s vertically integrated organised crime or something like carding forums, physical access exploitation is bound to become a problem.
