European supermarket cyberattacks highlight the need for secure remote access to refrigeration systems, says Secomea
The incidents disrupted cooling equipment and caused spoiled food as retailers face growing risks from remotely connected operational technology, Secomea said.
On November 2, 2026, supermarket chains across Europe reported a new wave of suspected cyberattacks targeting refrigeration systems, following similar attacks in French stores weeks earlier that caused substantial food losses.
Operational technology relying on external connectivity for remote monitoring faces increasing security risks. "Many organizations have invested heavily in securing their corporate IT environments," says Michael Ferdinandsen, CEO at Secomea, a Danish industrial cybersecurity company.
Richard Horne, CEO of the National Cyber Security Centre, admitted "vulnerable technology has been exploited" in two instances in the UK. GCHQ is alerting organizations across the food supply chain facing similar exposure.
The Defence Secretary urged Brits to stockpile necessities following the attacks, while NCSC and GCHQ officials worked through the night alerting organizations with exposed technology throughout the food supply chain.
Security expert Will Geddes warned that AI-boosted attacks on critical national infrastructure could happen within the next two months, contradicting earlier reports suggesting a two-year timeline and underscoring urgent threat assessment.
Within a few weeks, refrigeration equipment from large supermarket chains will have been remotely manipulated, this time in seven European countries, without the authorship being identified. Refrigerators and freezer arches from supermarkets in seven European countries have broken down after their thermostats have been altered remotely, in some cases to [...]
