The European Union’s (EU) cyber chief has urged Europe to prepare for attacks against routers and home appliances after a recent spree of hacks against supermarket fridges was pinned on Iran.

"Today it was fridges, tomorrow it could be routers, the day after tomorrow it could be home appliances, and so forth,” Lepassar told Agence France-Presse.

France points the finger at Iran France was worst affected by the fridge hacks.

Though authorities have not disclosed how hackers made their way into European fridges, French cybersecurity agency ANSSI confirmed October’s attackers had targeted fridge controllers from Danish manufacturer Danfoss, US company Copeland, and one of its affiliate brands, Dixell.

Research firm Claroty said it had uncovered Danfoss and Copeland device vulnerabilities weeks before Europe’s fridge attacks and could exploit them in less than 30 minutes using a common AI tool.
