Critical Infrastructure Under Siege, From Freezers to Wider OT

What happened?

The refrigeration cyberattack campaign that hit about 700 French supermarkets on October 11, 2026, is now a multi-country pattern of attacks on critical infrastructure. A second wave struck food businesses in 13 countries on November 2, cold rooms at a contractor for France’s national blood service were set to 110°C (230°F), and three UK meat suppliers were hit through Copeland XWEB controllers. On November 5, five US agencies warned of ongoing attacks on refrigeration and cold chain systems.
