Fridge hack costing millions and sparking fires stemmed from poor security

Earlier this week, a mass hack of refrigeration systems at an estimated 700 supermarkets throughout France caused them to suddenly malfunction, causing spoilage of untold tons of perishables and, in some cases, fires. As is now the norm, basic cybersecurity would have prevented it. French authorities say the systems, made up of entire fleets of refrigerators and freezers throughout a store, were hacked.
