  • •U.S. agencies warn retailers to strengthen cybersecurity against potential similar attacks.

U.S. agencies issued a warning on November 5, 2026, about cyberattacks targeting refrigeration systems crucial for food and medicine. These attacks have affected hundreds of supermarkets in Europe, with incidents reported in France, Belgium, and other countries, causing temperatures to rise dangerously high and resulting in significant food spoilage. The Cybersecurity and Infrastructure Security Agency (CISA) and the FBI advised U.S. retailers to strengthen their cybersecurity measures, including updating passwords and securing internet-accessible systems. The attacks exploited vulnerabilities in refrigeration controllers, particularly those that are unpatched or have weak security settings. While no U.S. supermarket has been publicly confirmed as a target, incidents at military commissaries are under investigation. The French Foreign Minister has attributed the attacks to the Islamic Revolutionary Guard Corps of Iran, marking a significant escalation in cyber threats to critical infrastructure.
