Researchers warned attackers could 'defrost the food' months before French supermarkets got hit
Attackers compromised exposed Danfoss and Copeland refrigeration controllers, spoiling food at nearly 700 French supermarkets.
Unknown criminals compromised internet-exposed refrigeration controllers and raised temperatures as high as 50°C, spoiling food and sparking fires across nearly 700 French supermarkets. France’s ANSSI said Danfoss controllers were widely compromised and later added Copeland and Dixell systems. Claroty’s Team82 had warned in August of authentication-bypass and OS command-execution flaws in Danfoss AK-SM 800A and Copeland XWEB devices, after earlier CISA advisories. Coalition scanning still found 1,506 exposed Danfoss StoreView panels and 1,119 XWEB login pages, with many remaining online after the attacks.
