Whether it was youngsters proving their skills or state sabotage, Europe’s most hacked country was left with a mountain of waste after food began cooking in freezers

Shortly before midnight last Sunday, the digital thermostats controlling hundreds of supermarket cold aisles across France began to flicker and rise.

In a “bizarre and unprecedented” cyber-attack, hackers had remotely overridden the temperature settings on thousands of freezers, fridges and chiller cabinets pushing them from as low as -27C (-16.6F) to well over 50C (122F).

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.

A massive French supermarket cyberattack targeted Danfoss refrigeration systems, causing catastrophic food spoilage and fires across 400 retail locations.
