U.S. Agencies Warn Refrigeration Controller Attacks Could Cause Fires and Inventory Losses

US government agencies are warning of attacks on industrial refrigeration and cold-chain monitoring systems worldwide, which could lead to disruptions, fires, and inventory losses. Threat actors are targeting these systems to cause harm. The attacks involve exploiting vulnerabilities in unpatched or internet-accessible controllers, allowing actors to remotely alter settings. This can force units into continuous heating, potentially causing damage. The goal of these attacks is to disrupt service and cause physical harm. Agencies are alerting organizations to this potential threat to their systems.
