It’s a supermarket, staff will be stocktaking, restocking, walking past A LOT.

True, but they'd need to be specifically checking a thermometer or it might warm up a fair bit before being noticed.

  • Any industrial fridge, even many home fridges, have a sound alarm if some temperature threshold is reached. It is trivial to _send_ alerts if the threshold is crossed. What is less common is remote control.

    E.g. the -80°C's in our lab are all naturally air gapped: the monitoring system is send-only.

  • It’s kind of a low-grade risk though, don’t you think? I imagine it’s unlikely we’d see major changes over “some stores lost a few hundred grand due to a cyber attack”.

    I suppose it could expand, but even still, there’s plenty of non-perishable foods. It would be annoying at worst, but maybe never outright dangerous?

    • It is not a low grade risk at all, these represent extreme health risks to the customer.

      It may be some time before staff notices a unit is heating up. And if customers aren't paying attention and grab something biologically fragile like milk they could get food poisoning that could hospitalize you for days.
