Cyberattack Triggers Refrigerator Shutdowns and Fires Across French Supermarkets

Major French supermarket chains suffered an unprecedented cyberattack on Monday that caused refrigeration systems to spike in temperature, spoiling stocks and sparking fires.

Retailers including Intermarche, Cooperative U, and E Leclerc confirmed hundreds of stores were targeted, with Paris prosecutors launching an investigation into the large-scale incident.

French authorities identified a software vulnerability in legacy equipment from Danish manufacturer Danfoss and are coordinating with European counterparts to prevent further spread.
