Bridgestone Americas experienced a **limited cyber incident** that disrupted manufacturing operations at multiple North American facilities, including plants in **Aiken County, South Carolina**, and **Joliette, Quebec**. The breach was detected at **2:00 AM local time** via unusual network traffic and unauthorized access attempts targeting the **SCADA (Supervisory Control and Data Acquisition) systems**, critical for production control. While the attack **halted production lines temporarily**, the company swiftly contained the incident by isolating affected VLANs, deploying EDR agents, and verifying backup integrity. No **customer or employee data** was compromised, and operations resumed after implementing disaster recovery measures. The attack bore similarities to a **2022 ransomware incident linked to LockBit**, though no formal attribution has been made. Bridgestone’s existing cybersecurity framework (MFA, network segmentation, and 24/7 monitoring) aided rapid mitigation. A forensic investigation is ongoing to identify the **attack vector, malware, and potential zero-day exploits**. Despite the operational disruption, the company emphasized **no data exfiltration** and reinforced trust through transparency, committing to a post-incident report.
