Five U.S. agencies warn of global attacks on refrigeration systems

CISA, the FBI, HHS, USDA and DOT warn of ongoing cyber activity targeting industrial refrigeration and cold-chain monitoring systems worldwide. These systems are used across healthcare, chemicals, food and agriculture, and transportation. The agencies say attackers target weaknesses in temperature and commercial refrigeration controllers, particularly devices that are unpatched or accessible from the internet. If exploited, the controls could change temperatures, spoil inventory, damage equipment or create fire hazards. The agencies urge operators to disconnect systems from the internet, strengthen passwords, apply patches and replace unsupported legacy devices.
