Suspected Cyberattacks Alter Freezer Temperatures in Supermarkets Across Seven European Countries

Suspected cyberattacks on Monday altered refrigeration temperatures in supermarkets in seven European countries, forcing stores to pull food from sale, according to the 10 Things Global News briefing of 3 November. The countries named are Belgium, Luxembourg, Sweden, Ireland, the Netherlands, Finland and Estonia. Some freezers reportedly reached 50 degrees Celsius. No group has claimed responsibility, and the cause is described as suspected rather than confirmed.

The incidents resemble attacks in October that affected about 700 supermarkets in France. The latest disruptions reportedly involved equipment made by Danfoss, whose older controllers remain exposed to the internet. The briefing does not say that the company has confirmed a fault in its products, and it does not name the affected retailers.

Researchers counted nearly 5,000 vulnerable systems last week. That number fell to about 1,000 after Monday’s incidents, which suggests some operators have since disconnected or secured exposed controllers, though the briefing does not explain the drop.

The pattern shows how attackers can cause physical harm and financial loss without stealing data, simply by changing settings on connected equipment. For retailers, the practical result is spoiled stock and disrupted shelves rather than a data breach.

The briefing cites the Japan Times and the BBC for the story. Those pages could not be opened directly during research, so the details here rest on the briefing’s summary. Attribution, the full extent of losses and any official investigation findings are still unreported.
