Hackers Remotely Overheated French Supermarket Freezers in Mass Cyberattack
Thousands of refrigeration units across France were pushed from sub-zero to scorching temperatures, destroying food in what officials called a bizarre and unprecedented attack.
A coordinated cyberattack on French supermarket refrigeration systems late Sunday caused widespread food spoilage after hackers remotely manipulated digital thermostats controlling cold aisles in hundreds of stores across the country. The intrusion, described by authorities as both bizarre and unprecedented, sent freezer temperatures soaring from as low as -27C to well above 50C in a matter of hours.
The attack struck shortly before midnight, a timing that limited immediate human oversight and maximized the damage before staff could respond. Thousands of freezers, refrigerated display cases, and chiller cabinets were affected, leaving retailers facing substantial food waste and significant financial losses.

France, already regarded as Europe's most frequently targeted nation for cyberattacks, now confronts new questions about the vulnerability of critical commercial infrastructure to remote digital intrusion. The incident highlights how internet-connected industrial control systems — in this case, networked thermostats — can serve as attack vectors well beyond traditional IT targets such as databases or payment systems.
Investigators have not yet publicly identified the perpetrators or their motive. Speculation ranges from opportunistic hackers seeking to demonstrate technical capability to the possibility of state-sponsored sabotage, though no attribution has been confirmed. The scale and precision of the operation suggest a degree of planning and network access that goes beyond casual intrusion.
The episode raises urgent questions for food retailers throughout Europe about the security standards governing building management and refrigeration control systems, many of which were not designed with robust cybersecurity protections in mind. Continue reading at Business | The Guardian.
