Europe's fridges are getting hacked. Could America be next?

Suspected cyberattacks sent refrigerator and freezer temperatures soaring at dozens of European supermarkets overnight, spoiling food and threatening costly losses. Grocery chains Ahold Delhaize and Colruyt reported incidents in Belgium and Luxembourg, while Swedish chains ICA and Coop saw similar disruptions. A Belgian firm said hackers switched units into defrost mode. The Pentagon is investigating suspected attacks at six U.S. military commissaries.
