Refrigeration control systems connected to the public internet are leaving commercial grocery stores, warehouses, and medical facilities vulnerable to remote temperature manipulation, fires, and massive inventory loss.
The warning follows a series of recent attacks across Europe and North America that disrupted commercial food distribution and medical storage. On November 2, a supermarket in Stockholm, Sweden, suffered extensive food waste after attackers compromised its remote refrigeration control system and ruined perishable inventory, chosun.com reported.
Securing Industrial Cold Storage Networks
- Federal authorities urge immediate isolation of internet-connected refrigeration and temperature control systems from public networks and internal corporate IT architectures.
- Operators are advised to deploy emergency software updates and assume their facilities are active targets for cyber intrusions.
Federal Agencies Warn of Critical Infrastructure Vulnerabilities
Reuters reported that these agencies identified widespread vulnerabilities in internet-connected temperature and refrigeration control devices utilized by grocery stores and cold storage warehouses.
According to federal authorities, successful cyber intrusions allow malicious actors to alter internal storage temperatures remotely. This manipulation risks destroying stored goods, sparking fires, and shortening the operational lifespan of expensive industrial machinery.
CISA Acting Assistant Director for Cybersecurity Chris Butera emphasized that any organization relying on refrigeration and monitoring systems must assume they are direct targets for threat actors. Meanwhile, FBI Cyber Division Operations Section Chief Brett Lederman noted that similar attacks targeting these control systems have been observed across major critical infrastructure sectors worldwide.
Recent Attacks Disrupt Global Food and Plasma Supply Chains
On November 2, more than 100 stores across Europe were affected by cooling system disruptions.
AP News reported that on November 2, hackers targeted a refrigeration equipment supplier serving the French Blood Establishment (EFS), causing temperature and defrost settings to spike abnormally across three plasma storage facilities. Although the targeted facilities stored blood plasma designated for transfusions and pharmaceutical manufacturing, staff members identified automated alarms quickly enough to relocate the sensitive supplies, preventing any actual loss.
Federal regulators are now pressing facility operators to disconnect vulnerable hardware from the public internet entirely. Agencies also recommended isolating these operational networks from corporate IT systems and applying vendor-supplied software patches immediately.
