Cyberattack on Connected Fridges in France
published on 2026-10-14 14:10:22 UTC by Bruce SchneierContent:
Another IoT cyberattack, this one in France:
Hackers gained control of the software that regulates the temperatures of the refrigeration units, forcing some to warm to 50C (120F) overnight, according to one supermarket chain affected.
[…]
Normally, supermarket freezers go through a short period of defrosting overnight, in which temperatures rise slightly. But the hackers ordered the units to heat up and stay hot, although Danfoss did not confirm any reports about just how warm the fridges and freezers could become in that process.
Danfoss said the affected cold units were older models whose security software could not be updated to ward off a risk they had identified.
Any IoT device that can’t be updated is vulnerable. And, probably, any IoT device that can be updated is also vulnerable.
