   Poor Security Led to Cyberattack on 700 French Supermarkets

   A coordinated cyberattack on October 11, 2026, targeted refrigeration controllers at approximately 700 French supermarkets, heating units to 122°F. The breach exploited known critical vulnerabilities in outdated, internet-connected devices, causing widespread food spoilage and electrical fires. Losses are estimated in the millions of euros, with one store reporting $112,000 in food waste. The Paris prosecutor has reported fires resulting from the malfunction. While investigators are hunting the perpetrators, no group has claimed responsibility for the attack. Insurers indicate that cyber insurance is unlikely to cover the resulting food losses.

   Why it matters

   The incident highlights the risk of connecting industrial controllers to the internet without updating security patches. Researchers had warned months prior that attackers could potentially defrost food using these vulnerabilities. Affected retailers include Carrefour Market, Monoprix, Netto, Intermarché, the U cooperative, and E.Leclerc.
