Hackers push European supermarket freezers to 122F in sabotage wave

Attackers reached refrigeration control systems and raised temperatures at stores run by Carrefour, Coop, ICA and Ahold Delhaize, with no ransom demanded.

Supermarkets in Sweden, Belgium, Luxembourg and Ireland lost refrigerated and frozen stock on Monday after hackers remotely altered temperature settings.

Zoom in: Freezers at an ICA store in Stockholm reached 50C (122F), and a Belgian butchery watched its cold room climb to 18C (64F). Carrefour reported 15 of its 700 Belgian stores hit and Coop reported 7 of 800 in Sweden.

  • "Everything is destroyed," said Engla Ingwall, a sales manager at ICA Stockholm. "There has been a cyberattack and all our freezers reached 50 degrees."
  • Musgrave said 13 SuperValu stores in Ireland were affected, and at least one IKEA store in Belgium reported a problem.

The backstory: The same playbook ran in France last month, when hackers seized cooling units at hundreds of supermarkets and caused fires and food losses. Ahold reported a cybersecurity incident to police last month as well.

  • "It's very scary. They are hacking the system that is doing the registration of the temperature," said Luc De Laet, founder of the De Laet & Van Haver butchery.

Between the lines: Nobody claimed responsibility and nobody asked for money, which points security experts toward sabotage over extortion. The affected units trace back to Danish refrigeration firm Danfoss.

What they're saying: "All IT systems are potentially vulnerable, and AI can now be used to successfully exploit these weaknesses," said Katrien Eggers, a spokesperson for Belgium's Centre for Cybersecurity.

Why it matters: A thermostat is now an attack surface. Grocers across four countries binned stock without a single till system going down, which makes the damage physical, the loss immediate and the fix slow.
