Is Britain NEXT? 🇬🇧The UK is on alert to protect its 2 BIGGEST supermarkets as fridge CYBERATTACKS spread across Europe. Together, Tesco and Sainsbury's hold 43% of Britain's grocery market. Both use fridges from Danfoss, the same supplier behind fridges hacked in France and Sweden, per The Telegraph. In France, hackers broke into older Danfoss fridge controllers over the internet. Many hacked fridges there heated to about 50°C, and one store reported 80°C. No UK stores have been hit so far, but Britain's cyber agency is urging retailers to patch their systems.
