Hackers target refrigerators at French supermarkets, overheating them and causing fires

A large-scale cyberattack targeted the refrigeration systems of multiple major French supermarket chains, including E. Leclerc, Intermarché, and Coopérative U. Hackers remotely manipulated temperature controls, causing fridges and freezers to heat up to 50°C (120°F) in approximately 500 stores. The incident resulted in massive food waste, financial losses estimated in the millions of euros, and isolated instances of fires. Authorities and the Danish equipment manufacturer Danfoss identified the vulnerability in legacy software that was no longer receiving security updates. Investigations by Paris prosecutors and the French cybersecurity agency ANSSI are underway.
