What happened
US agencies including CISA and the FBI issued a warning on November 5 about industrial refrigeration and cold-chain monitoring systems, following attacks on supermarket refrigeration across Europe. Danfoss said affected systems were reachable through unsecured connections and used default passwords, and at least 17 mainly small businesses in the Netherlands were compromised. The agencies advise keeping control panels off the public internet, isolating operational technology from business networks, and changing default passwords.
