Bridgestone Americas experienced a **limited cyber incident** that disrupted manufacturing operations at several North American facilities, including plants in **Aiken County, South Carolina**, and **Joliette, Quebec**. The attack targeted the **SCADA (Supervisory Control and Data Acquisition) network**, halting production lines temporarily. Security teams detected **unusual network traffic and unauthorized access attempts** at ~2:00 AM local time, prompting immediate isolation of affected VLANs, activation of the Cybersecurity Operations Center (CSOC), and verification of offline backups. While production was paused, employees were offered paid maintenance work or unpaid leave. The company confirmed **no customer or employee data was compromised**, and operations resumed swiftly. Investigations suggest potential ties to **LockBit ransomware tactics** (similar to a 2022 attack on Bridgestone). The incident highlighted gaps in patch management and zero-day exploit risks, though existing defenses (MFA, network segmentation, EDR) aided rapid containment. A full forensic review is underway to assess residual effects and strengthen future resilience.
