π° What Happened
US cybersecurity agencies have warned of an ongoing threat to industrial freezers and fridges. CISA, the FBI and other federal departments said hackers are breaking into internet-connected cooling and temperature monitoring systems. Targets include supermarket refrigeration, cold storage warehouses, US military bases and at least one blood bank.
The agencies said attackers could raise or lower temperatures. That could cause fires, spoil stock and shorten the working life of equipment.
π The Backstory
The warning follows two waves of attacks in Britain and Europe in recent weeks. Hackers turned up the heat on freezers in at least a dozen countries, ruining food and produce.
Some affected units were made by Danish company Danfoss and ran software that no longer gets security fixes. A blood bank in France was also hit, with its refrigerated units forced to warm up. The joint statement said the food, farm, transport and medicine industries are all exposed.
π― Why It Matters
Food and medicine move through cold chains, so a hack on a fridge can empty shop shelves or spoil blood supplies.
