Hackers raised the temperature of numerous refrigerators in supermarkets in France to 50 degrees Celsius overnight, causing fires and food loss in hundreds of stores across the country as part of a widespread cyberattack. The Paris prosecutor's office said major food chains across the country were affected, and Prime Minister Sébastien Lecornu ordered an investigation into the incident. The Carrefour food chain said 80 of its 6,000 stores in the country were affected.
