Contradicted by other sources

  1. Contradicted Sweden's Coop chain told the daily Aftonbladet that six of its shops had been hit.

    AI The ESM Magazine headline reports that the cyber attack affected 800 Coop Sweden stores, which is incompatible with the claim that six shops were hit. No result mentions Aftonbladet or a statement to it, so that attribution could not be checked. The BBC results describe shut Coop shops but give no count.

Verified facts

  1. Confirmed Supermarket chains in at least seven European countries said the temperatures of refrigerators and freezers in some of their shops soared overnight to as high as 50C (122F).

    AI Beinsure reports that a cyberattack disrupted supermarket refrigeration across seven European countries on November 2, 2026, with temperatures in some fridges and freezers rising to 50C (122F), which matches the claim's core. The BBC confirms the overnight outage in Belgium and Sweden, and the Hacker News thread describes units pushed to over 50C at chains such as Carrefour and Leclerc, though it is a forum comment. The results do not clearly show each chain itself making the statement, so that attribution is only loosely supported.

  2. Confirmed Retailers in Belgium, Estonia, Ireland, Finland, Luxembourg, the Netherlands and Sweden reported problems with their refrigeration systems on Monday.

    AI The NZ Herald snippet explicitly lists supermarkets in Belgium, Estonia, Finland, Ireland, Luxembourg, the Netherlands and Sweden as affected by the latest attack, and Euronews places the Belgian attack between Sunday night and Monday morning, which supports the Monday timing. Industrial Cyber corroborates the refrigeration problems in Belgium, Luxembourg and Ireland. The results do not separately confirm the Estonia detail beyond the NZ Herald list, and several of these sources may trace back to the same underlying reporting.

  3. Confirmed In France last month, hackers seized control of cooling units in as many as 700 supermarkets and raised their temperatures as high as 50C.

    AI Several results report that hackers hit refrigeration systems at French supermarkets and heated some units to 50°C, and that about 700 stores were affected, with Finance Minister Roland Lescure cited for the 700 figure. Bloomberg reports only about 150 Intermarché stores, which is consistent with the 'as many as 700' wording. The exact date of 'last month' could not be checked against the results.

  4. Confirmed The French cyber-attack caused fires and food losses estimated in the tens of millions of euros.

    AI Several results support the core claim that the attack's food losses were estimated at tens of millions of euros, with Intermarché CEO Thierry Cotillard as the source of the estimate (Reuters and BFM TV reporting). None of the results mention fires, which could not be checked, and the results describe refrigerators being set to defrost rather than causing fires. The supporting results largely repeat Cotillard's statement, so the estimate has a single origin.

  5. Confirmed EU food and agriculture commissioner Christophe Hansen said the repeated cyber-attacks were deeply concerning and described them as "a deliberate attempt to disrupt our food supply chain".

    AI Several results quote EU agriculture commissioner Christophe Hansen calling the attacks "a deliberate attempt to disrupt our food supply chain" and saying their repeated occurrence is "deeply concerning". The Reuters report (result 3) is the original source, and the other results repeat its quotes, so they are not independent confirmation.

  6. Confirmed Ahold Delhaize said fridges and freezers in dozens of its supermarkets in Belgium and Luxembourg had been hit.

    AI Several results state that Ahold Delhaize and Colruyt said an overnight IT incident sent temperatures soaring in fridges and freezers at dozens of stores in Belgium and Luxembourg, which matches the claim. The CBS and Independent pieces appear to repeat the same Reuters-sourced reporting, and Al Jazeera attributes the cyberattack blame to the Sabcobel CEO rather than Ahold Delhaize, which does not contradict the claim.

  7. Confirmed Stephan Moelans, chief executive of Sabcobel, told Belga news agency that the incident affecting Delhaize refrigeration systems had been a cyber-attack.

    AI Several results report that Stephan Moelans, CEO of Sabcobel, told Belga that the incident affecting Delhaize's refrigeration systems was a cyber-attack. The Belga article itself (result 3) is the primary source, though it does not name Delhaize in the snippet; the other results repeat the same report.
