On the night of October 11 to 12, attackers took remote control of the systems regulating refrigeration in some 700 supermarkets and shops in France. They did not steal data or demand a ransom: they only activated the defrost function of the appliances and extended it so the chambers would heat up. The president of the Intermarché chain acknowledged that it reached 50 °C. According to the French government, there were at least 15 attempted fires and food worth tens of millions of euros was ruined.
