## Key points

- Hackers have disrupted refrigeration systems in five European countries.
- The attacks have spoiled food and sparked fires.
- US agencies urge operators to secure connected equipment.

## Summary

US federal agencies have warned operators of industrial refrigeration and cold chain systems to strengthen their cyber defences after hackers disrupted thousands of supermarket refrigeration units in Europe. The attacks show how weaknesses in connected equipment can spoil food, damage machinery and create hazards for consumers.

Since mid-October, systems in grocery stores across France, Belgium, Ireland, Luxembourg and Sweden have reportedly been forced to heat fridges to as high as 50°C, spoiling food and sparking fires. No digital attacks on American supermarket refrigeration systems have been documented in the article, but US authorities cited risks from internet-accessible or unpatched controllers. Their advice includes disconnecting equipment from the public internet, using firewalls for necessary remote access, isolating operational technology networks, replacing default passwords, enabling multifactor authentication and applying patches.
