U.S. government agencies have warned that threat actors are actively targeting industrial refrigeration and cold-chain monitoring systems worldwide. The agencies say the attacks aim to cause service disruptions, fire hazards, and loss of inventory.
According to the warning, the actors may exploit vulnerabilities or weaknesses in controllers that are unpatched or accessible from the internet. They could use this access to remotely change settings and force units into continuous heating.
The report does not name the threat actors, identify specific affected products, or list any CVEs. It also does not describe confirmed incidents.
