In a recent incident, hackers compromised refrigeration controls at hundreds of French supermarkets, raising temperatures to over 122 degrees Fahrenheit, resulting in significant food spoilage and financial losses estimated at €270,000 ($300,000). The affected stores included major chains like Carrefour and Intermarché. Following this, the Pentagon is investigating similar freezer failures at U.S. military commissaries that occurred in August, treating them as a potential cyberattack. While there is currently no proof linking the two incidents, the timing and nature of the outages have raised suspicions among experts. The Pentagon's investigation involves collaboration with French authorities to determine if the incidents are connected. The scope of the attack highlights a growing concern over the cybersecurity of critical infrastructure related to food supply and military logistics.
