US Agencies Warn of Ongoing Cyber Threat to Cooling and Refrigeration Systems | Integri News

The Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA) have issued a joint warning about an ongoing cyber threat. The threat targets cooling systems and industrial refrigeration equipment across the United States. According to the agencies, these attacks have already disrupted operations at some businesses, including supermarket freezers.

Cooling and refrigeration systems are used in many places that Americans depend on every day. Grocery stores use them to keep food fresh, and warehouses use them to store medicine and other goods that must stay cold. When these systems stop working properly, food can spoil and businesses can lose money. In some cases, temperature problems can also create safety risks for customers.

The warning explains that attackers are trying to gain access to the computer networks that control these machines. Once they enter a system, they can change settings or stop equipment from working. The agencies say that many of these systems are connected to the internet to make them easier to monitor and manage. This connection can also make them easier targets if security is weak. The FBI and CISA recommend that owners and operators take several steps to protect their equipment. These steps include changing default passwords, limiting remote access, and keeping software up to date.

The agencies encourage businesses, facility managers, and technology staff to review their security practices now. They also advise organizations to report any suspicious activity to the FBI or CISA. Officials stress that the threat is still active, so careful preparation remains important. Consumers are not being asked to take direct action, but people may notice changes in store products or services if disruptions continue.
