The FBI and CISA, along with other U.S. agencies, have issued a joint warning about ongoing cyber threats targeting industrial refrigeration and cold-chain monitoring systems worldwide. These systems, used in healthcare, food production, chemical facilities, and transportation, are vulnerable to attacks that could cause food spoilage, equipment damage, and fire hazards. The agencies urge critical infrastructure operators to secure their systems by removing refrigeration controllers from the public internet, securing necessary remote access, changing default passwords, and applying available security updates. This warning follows a series of attacks in Europe, including incidents at French supermarkets and blood storage facilities, where hackers remotely altered temperature settings, leading to food spoilage and potential blood product contamination.
The FBI has also issued an international cybersecurity warning, highlighting the potential for hackers to disrupt essential services by exploiting vulnerabilities in industrial refrigeration and temperature monitoring systems. The warning comes as European authorities investigate bomb threats that have disrupted passenger flights and reached television stations, raising concerns about a wider campaign of hybrid aggression and psychological warfare.
