Unpatched Fridge Firmware Costs European Grocers Millions

Key Takeaway
If a third party manages your connected equipment, such as refrigeration or building systems, ask them in writing how and when firmware is updated and check that it actually happens.
Hundreds of grocery stores in the European Union have suffered significant financial losses tied to outdated firmware in their refrigeration and cooling systems. According to Dark Reading, the losses reached millions of dollars.
The stores had hired third parties to manage the operational technology (OT) that runs these cooling systems. The firmware on that equipment was out of date, and outsourcing its management did not keep it current.
The case is a reminder that everyday equipment such as fridges and building controls can carry the same patching risks as office computers. Handing the job to an outside provider does not remove the responsibility for knowing whether that equipment is being maintained.
