Refrigeration Cyberattack Campaign Expands Across Multiple Countries Target OT Systems

SOCRadar reported on November 9, 2026, that a cyberattack campaign targeting refrigeration systems and operational technology has expanded into a multi-country threat. The attacks began on October 11, 2026, when hackers targeted approximately 700 French supermarkets. A second wave hit food businesses in 13 countries on November 2, 2026. [1]

According to SOCRadar, the campaign has caused physical temperature manipulations across affected operational sites. Cold rooms at a contractor for the national blood service in France were altered to reach 110°C. Additionally, three meat suppliers in the United Kingdom were compromised through vulnerable Copeland XWEB controllers. [1]

Commercial refrigerators maintain temperatures slightly above freezing to prevent food spoilage, with optimal storage ranging from 3 to 5 °C. Freezers and thermal insulation systems rely on precise heat transfer mechanisms, making automated control systems crucial for maintaining safe environmental parameters. [4]

SOCRadar noted that additional freezer systems were targeted in Belgium, Sweden, and Luxembourg. Following the escalation of the attacks, five United States agencies, including the Federal Bureau of Investigation and the Cybersecurity and Infrastructure Security Agency, issued a joint warning on November 5, 2026, regarding ongoing threats to cold chain systems.
