Cyberattack on Connected Fridges in France

A cyberattack in France targeted connected fridges, allowing hackers to control the temperature regulation software. The attackers forced some refrigeration units to warm up to 50C overnight, according to a supermarket chain that was affected. Normally, these units undergo a brief period of defrosting with slightly elevated temperatures, but the hackers caused them to heat up and remain hot. The affected cold units were older models, and the manufacturer Danfoss did not confirm the maximum temperature they could reach during the attack. The incident highlights a vulnerability in older IoT devices. Danfoss is aware of the issue, which involved their older models.
