European supermarkets hit by remote freezer attacks
French minister names Iran; connected cooling systems also run in hospitals, medicine warehouses and data centres
Hackers remotely raised the temperature of freezers in dozens of supermarkets across at least 11 European countries on 2 November, the second such wave after hundreds of French stores were attacked in October. French Foreign Minister Jean-Noël Barrot has blamed Iran and called for European sanctions. The incidents have exposed vulnerabilities in internet-connected cooling systems that also serve hospitals, medicine warehouses and data centres. Two days after the French attack, the Australian Signals Directorate issued an alert to businesses running refrigeration and cooling systems.
