It meansto have all devices interconnected between them (not only referring to LANs but meanly when they rely to internet, exposing delicated services or referring to the cloud).
Attackers Heat French Supermarket Fridges Up to 50°C by Hijacking Danfoss Controllers.
Danfoss told AFP that most of the units hit were older products that no longer get software or security updates (the AK-SM 800 and the AK-SC 355).
Danfoss declared the AK-SM 800 end-of-life in May 2021 and phased out the AK-SC 355 in 2016. In an October 2025 newsletter, it said it would end all services for such older products and urged customers to plan replacements.

These are impacted retailers.
