Cyberattacks Target Refrigeration Systems in Europe and US

• •Cyberattacks have targeted refrigeration systems in Europe and the US, causing food spoilage.
• •Hackers exploited vulnerabilities in internet-connected temperature controllers, raising temperatures significantly.
• •FBI and CISA issued urgent advisories for organizations to enhance security and remove systems from the internet.

A series of cyberattacks have targeted industrial refrigeration systems across Europe and the US, affecting grocery stores and cold storage facilities. The attacks, which began in October 2026, involved hackers exploiting vulnerabilities in internet-connected temperature controllers, causing temperatures to rise and resulting in food spoilage and potential fire hazards. The FBI and CISA issued a joint advisory on November 5, 2026, warning that these attacks could lead to significant inventory losses and equipment damage. Over 100 stores in multiple European countries were impacted, with reports of temperatures reaching as high as 50°C (122°F). The attacks have raised concerns about the security of critical infrastructure, particularly in sectors reliant on refrigeration for food and medicine. Authorities recommend organizations immediately remove these systems from public internet exposure and implement stronger security measures. The identity of the attackers remains unknown, although pro-Russian hacktivist groups have been speculated to be involved.
