Executive Summary
In early September 2025, Bridgestone Americas confirmed it had suffered a cyberattack at its manufacturing facilities, including plants in South Carolina (Aiken County) and Quebec (Joliette). The incident disrupted production briefly. Fortunately, customer and employee data were not compromised, likely due to rapid containment. Investigations are underway, and operations have reportedly returned to normal. However, early signs suggest potential ransomware parallels, making this a critical case for manufacturers and supply chain leaders.

Technical Indicators & Risk Analysis
- No public attribution to ransomware groups yet, but similarities to the 2022 LockBit attack raise concern. CybernewsBleepingComputer
- A short incident window and lack of data loss suggest a focused and swiftly mitigated intrusion.
- The scope—multiple plants—implies possible lateral movement and access to OT networks.
Supply Chain & Manufacturing Cybersecurity Risks
Bridgestone’s experience highlights:
- The growing attractiveness of manufacturing as a target for industrial disruption.
- The need for segmented network architecture, incident detection on OT endpoints, and robust crisis response playbooks.
- The optics: even “limited” incidents can fuel speculation and supply chain instability.
