Hackers Turn Supermarket Freezers Into Ovens

A Wake-Up Call for Retail OT: Hackers Weaponize Supermarket Cooling Systems Across Nine Countries

Tue, Nov 03 2026 /Mpelembe Media/ — In October and November 2026, a coordinated wave of cyber-physical attacks compromised commercial refrigeration systems across hundreds of supermarkets in France and at least eight other European countries, including Belgium, Sweden, Luxembourg, Ireland, the Netherlands, Estonia, and Finland. Threat actors remotely hijacked internet-exposed supervisory controllers—chiefly Danfoss AK-SM and AK-SC series, as well as Copeland and Dixell XWEB units—manipulating operational parameters to force evaporators into continuous manual defrost modes. Cabinet and freezer temperatures soared to between 50°C and 55°C (122°F–131°F) for hours overnight, spoiling thousands of metric tons of perishable inventory across major chains such as Intermarché, Carrefour, Delhaize, Coopérative U, Coop, and ICA. The sabotage caused tens of millions of euros in direct stock and business losses, triggered temporary store closures, and led to localized electrical fires from thermal runaway in compressor units.

UpEnergy issues world’s first carbon credits linked to electric clean cooking devices deployed in sub-Saharan Africa

UpEnergy, a leading social enterprise based in Kampala, Uganda, announced it has issued the world’s first ever carbon credits linked to emissions savings from the use of electric clean cooking devices. The emissions reductions were created in a new UpEnergy-led project aimed at replacing traditional, biomass burning stoves with an innovative electric stove created by climate tech startup PowerUP. The PowerUP electric pressure cooker (EPC) is designed for low-income households in several countries across sub-Saharan Africa. The credits, which are verified by The Gold Standard, represent the opportunity for African consumers with access to electricity to abandon the toxic burning of unsustainable, wood-based fuels and breathe cleaner air with healthier, zero-emissions electric cooking.
