On November 2, 2026, cyberattacks affected supermarket refrigeration systems in Sweden, Belgium, Luxembourg, and Ireland, causing temperatures to rise to 50°C and spoiling food stock. This incident follows a similar attack on French supermarkets in October. The affected systems primarily used refrigeration controllers from Danfoss, which had known vulnerabilities identified by Claroty. Despite patches being available, many systems remained, allowing attackers to exploit these weaknesses. The Irish National Cyber Security Centre indicated that the recent incident may be linked to a known vulnerability. No group has claimed responsibility for the attacks, and the exact attack vector remains unconfirmed.
