US government urges protection against cyberattacks on refrigeration systems

The US federal government is urging businesses to implement cybersecurity measures to protect refrigeration systems connected to the internet, according to Retail Dive. This call follows a series of cyberattacks targeting supermarkets in Europe that manipulated refrigeration temperatures, causing fires, spoiled food, and significant financial damage.

Hackers exploited vulnerabilities in programmable controllers regulating commercial refrigeration, raising temperatures to dangerous levels such as 120 degrees Fahrenheit, Retail Dive reported. These attacks not only risk inventory loss but also pose potential fire hazards and health risks to consumers due to unsafe food storage.

The US government recommends that owners and operators avoid connecting control system devices to the public internet, keep device firmware updated, and report any unexpected activity immediately. This joint statement involved the USDA, Health and Human Services, and the Department of Transportation, which oversee sectors using industrial refrigeration and cold chain monitoring systems.

Earlier incidents in Europe included a second wave of attacks resetting refrigeration controls to defrost and an attack on the French Blood Establishment's cold storage, affecting blood supply storage. These events highlight the critical need for enhanced cybersecurity in refrigeration systems.

The US initiative aims to prevent similar disruptions domestically by encouraging proactive cybersecurity practices among businesses reliant on refrigeration technology.
