CISA Urges Hardening of Industrial Refrigeration Systems
Original title: US Government Partners Urge Hardening Industrial Refrigeration and Cold Chain Monitoring Systems
Malicious actors may exploit vulnerabilities in refrigeration controllers to alter temperatures and cause inventory loss.
CISA, FBI, HHS, USDA and DoT warn of targeted malicious activity against industrial refrigeration and cold chain monitoring systems used in healthcare, food, chemical and transportation sectors. Actors may exploit unpatched controllers via authentication bypass, arbitrary code injection or weak configurations, potentially changing temperatures, causing heating cycles, inventory loss or fire hazards. Mitigations include eliminating internet exposure, isolating OT devices, applying patches, changing default passwords and maintaining backups.
- Exploitation vectors include auth bypass, code injection and weak configs
- Effects include temperature changes, inventory loss, fire hazards
- Urged actions align with CISA CPGs
- Report incidents to CISA or FBI
- Maintain offsite offline backups
Impact: changing temperature settings and causing equipment hazards in refrigeration systems
- 1.Eliminate public internet exposure of controllers
- 2.Isolate OT devices on separate VLAN
- 3.Apply patches and keep firmware updated
- Countries
- United States
