Cyber attacks on supermarket freezers expose Europe’s infrastructure vulnerabilities

Cyber attacks disrupted supermarket freezers across Europe, raising temperatures and forcing stores to discard food worth millions of euros. The incidents, alongside hoax bomb threats that disrupted flights and attempts to interfere with French blood bank fridges, highlight how connected infrastructure can be vulnerable to sabotage.

The article describes these incidents as “greyzone aggression”: hostile acts short of military conflict intended both to cause disruption and to unsettle the public. Those responsible for the freezer attacks are unknown, though Russian-linked hackers and other state or non-state actors are possible. The author argues that public preparedness matters, pointing to the UK’s Be Ready campaign and Sweden’s household crisis guidance as examples.
