Do you trust businesses to protect you when hackers disrupt the services you rely on?
Cyber attackers remotely altered temperature control settings on supermarket fridges and freezers across Europe over the past month, according to Oneglobal Broking. The machines kept running as designed, and most refrigeration units were not damaged.
Why it matters
Most cyber insurance wordings exclude physical loss or damage to tangible property, which can leave retailers without cover for spoiled food stock. The incidents show that a software-only attack can cause financial loss without any physical breakdown.
Cyber exclusions written in the London market remove loss caused by malicious use of a computer system, while property spoilage extensions typically respond to one compressor failing rather than multiple stores. Oneglobal Broking has not said how many units were affected or whether any claims have been paid.
The players
Oneglobal Broking
An insurance broker that advised retailers to review their cyber and property policy wordings after the attacks.
The details
Attackers reached refrigeration controls through computer systems and changed temperature settings without damaging the hardware. Oneglobal Broking advised retailers and food businesses to review whether their policy wordings respond to deterioration of stock caused by a cyber event.
Timeline
Over the past month, cyber incidents tampered with supermarket fridge and freezer settings across Europe.
The Tech Race
London market cyber exclusions remove loss caused by malicious use of a computer system, a standard carve-out that the remote fridge tampering now tests for supermarkets. The attacks show that operational technology in retail can be turned against stock value even when nothing physically breaks.
Retailers and food businesses should check whether their cyber and property policies pay for spoiled stock after a remote attack on refrigeration. Grocery shoppers may see effects only indirectly if stores face losses or disruption to chilled goods.
The takeaway
Review your cyber and property insurance wordings now, since a software-only attack on refrigeration may not be covered. Ask your broker specifically whether spoilage extensions respond when several sites are affected at once.
