CISA, FBI and three US departments warn of ongoing attacks on industrial refrigeration controllers
Cold chain controllers are now a live target for physical disruption, which puts grocers, pharmaceutical and blood-supply operators, and logistics providers in the exposed group. Operators should remove internet exposure and replace unsupported equipment first, and ask equipment suppliers for patch commitments. Insurers should expect operational technology exposure and spoilage losses to feature more prominently in underwriting questions and accumulation analysis.
What Happened
CISA, the FBI, HHS, USDA and DOT published a fact sheet warning of ongoing cyber threat activity against industrial refrigeration and cold chain monitoring systems. CISA says malicious actors globally are targeting vulnerabilities in unpatched or internet-accessible temperature and refrigeration controllers in retail grocery and cold storage facilities. TechCrunch reports that the agencies urged operators to take remote control systems off the internet, strengthen passwords, patch, and retire unsupported equipment. TechCrunch also reports that attackers targeted a French blood bank's refrigerated units, and that attacks have hit refrigeration units across the UK and Europe.
