Suspected hackers heat supermarket fridges to 50C across seven European countries
Supermarket chains in Belgium, Estonia, Ireland, Finland, Luxembourg, the Netherlands and Sweden said fridge and freezer temperatures in some shops rose overnight to as high as 50C, The Guardian reports. Several companies confirmed they had been hacked. Ahold Delhaize said dozens of its shops in Belgium and Luxembourg were hit, and Ireland's SuperValu said 13 of its 223 shops were affected. Sweden's cybersecurity centre said the country has many exposed control devices that need updating. It follows an attack in France last month on as many as 700 supermarkets. The EU food commissioner, Christophe Hansen, called it "a deliberate attempt to disrupt our food supply chain".
Why it matters: Remotely controlled equipment left exposed online can cause real physical damage. Shoppers may see empty chilled shelves, but food was removed from sale rather than sold spoiled.
