How do supermarkets stop hackers from switching their fridges to defrost?
Attackers switched supermarket refrigeration across Europe into defrost mode, months after a similar attack on US military commissaries, and most grocers have no visibility into the internet connected controllers that protect their stock.
Who has it: Operations and IT leads at regional grocery chains, convenience stores and cold storage operators.

Heard in public
“Why is that even internet enabled? If you want to defrost it presumably someone already needs to be physically present to unload the fridge?”

A lightweight cold chain security service for retail: discover exposed refrigeration and building controllers, lock down remote access, detect unusual commands such as mass defrost, and alert store staff in time to save the stock.
Tools that solve this
3 named so far, and where each one stops.
- Industrial OT security (Claroty, Nozomi, Dragos)
Strong, but built and priced for factories and utilities, not a 40 store grocer.
- Refrigeration vendor remote portals
Give remote control and alarms, but are often the exposed surface themselves.
- Temperature loggers (SensoScientific, ComplianceMate)
Alert on warm cases, after the attack has started.
How you might build it
- 01Passive network discovery of OT devices
- 02Protocol aware monitoring (BACnet, Modbus)
- 03Command anomaly detection
- 04Store staff SMS alerts
- 05Vendor remote access gateway
