Hundreds of French supermarkets saw their refrigeration systems defrosted, spoiling tons of frozen food. The unprecedented attack has raised serious questions about food security across Europe.

Hundreds of French supermarkets were forced to throw away perishable goods on Monday after hackers commandeered refrigeration systems across the country, spoiling stock at major chains in a sophisticated overnight cyberattack.

Hackers destroyed the food by taking control of refrigeration systems at Cooperative U, Leclerc, Les Mousquetaires, and Intermarche stores across the country and then defrosting thousands of freezer and refrigeration units.

During the overnight attack, in some cases, fully-stocked fridges were heated up to 50 degrees Celsius (122 degrees Fahrenheit) for more than six hours. Over 400 stores were hit according to retailers.

    i would like to know how the fuck some of them fridges got to be 50 °C. are they run on heat pumps and you can just crank them to whatever temperature with the software!? are they general purpose laboratory incubators!??!

      Defrost mode. https://www.bbc.com/news/articles/crq5nzxv9q4yo

      Normally, supermarket freezers go through a short period of defrosting overnight, in which temperatures rise slightly. But the hackers ordered the units to heat up and stay hot, although Danfoss did not confirm any reports about just how warm the fridges and freezers could become in that process.

      Industrial controls are terrifying in terms of just how catastrophically they can cause the device to fail. Connecting machines to the internet is an incredible liability.

      I once tried to beg the SCADA department to let me have a single line of sight radio transmitter for data collection. Not for control, and not even over the internet! They said no, which was the right thing to do.

        Yup, this. My cybersecurity plan for the fridges would be “what the fuck why are they exposed to any external networks for any reason?”
