CISA and Federal Partners Warn of Cyberattacks Targeting Industrial Refrigeration and Cold Chain Systems Across Europe

The U.S. Cybersecurity and Infrastructure Security Agency (CISA), along with the FBI, HHS, USDA, and DOT, has issued a warning about malicious cyber activity targeting industrial refrigeration and cold chain monitoring systems globally. Threat actors are exploiting unpatched or internet-accessible electronic temperature controllers in retail grocery stores and cold storage facilities, with attacks disrupting supermarket cooling systems across Europe. The advisory urges operators to eliminate direct public internet exposure of control systems, isolate operational technology (OT) devices, and strengthen authentication to prevent remote manipulation of temperature settings, which can lead to inventory losses and equipment hazards.
