Hackers reportedly changed temperature settings on refrigeration equipment used by the French Blood Establishment, EFS, from around −30°C to 110°C after targeting its cooling service provider, Coolworld.
I mostly agree. I can think of a few niche uses for it. However, they are very uncommon. E.g. bringing a freezer of blood up from “deep storage” temperatures to “ready to use in a hurry”.
I can also think of a few more where a “boost mode” could be useful e.g. a supermarket that knows there is a heat wave. Over-chilling the freezers would let them cope better with the temperature spike later in the day.
Critically, these should still be within safe hard limits. The fact that hackers could effectively switch them off in mass is the huge issue.
