FBI, CISA warn of cyberattacks targeting refrigeration systems

The FBI and CISA have issued a joint warning about active cyberattacks targeting industrial refrigeration and cold-chain monitoring systems globally. Threat actors are exploiting vulnerabilities in these operational technology (OT) and industrial control systems (ICS). The attacks pose significant risks including food spoilage, equipment damage, and potential fire hazards. Cold-chain systems are critical to food safety, pharmaceutical storage, and supply chain integrity. The advisory highlights the growing threat to critical infrastructure beyond traditional IT targets. Organizations operating refrigeration and cold-chain environments are urged to review their cybersecurity posture and apply recommended mitigations. This aligns with a broader trend of threat actors increasingly targeting ICS and OT environments with potentially physical consequences.
