Five U.S. agencies warn businesses of cyber threats to refrigeration systems
Five U.S. federal agencies issued a joint warning about ongoing cyber threats to commercial refrigeration systems across healthcare, agriculture, transportation and other industries. CISA urged businesses to change passwords, disconnect system devices from the internet and update software to address vulnerabilities. The agencies said attackers are exploiting unpatched or internet-connected systems but did not specify whether any refrigeration systems in the U.S. had been targeted.
