Bridgestone Americas confirmed on September 4, 2025, that it was investigating a limited cyber incident affecting some North American manufacturing facilities. Reports identified disruption at two plants in Aiken County, South Carolina, and at a facility in Joliette, Quebec. Bridgestone said it contained the incident early and did not believe customer data or interfaces were compromised; its forensic analysis was still underway.
What happened at Bridgestone?
Bridgestone Americas described the event as a “limited cyber incident impacting some of our manufacturing facilities,” according to BleepingComputer’s September 4, 2025 report. The company said its team responded quickly and contained the issue in keeping with established protocols.

The reporting characterized the event as a cyberattack affecting operations. Bridgestone’s public description, as quoted in that report, was “limited cyber incident”; it did not establish the technical method used or identify an attacker.
Which manufacturing facilities were affected?
Contemporaneous reporting identified two Bridgestone Americas production facilities in Aiken County, South Carolina, with reports of the Aiken disruption surfacing September 2, 2025. Canadian reporting on September 3 described similar disruption at the Joliette, Quebec, facility. These are locations identified by reporting, not a complete facility list published by Bridgestone. BleepingComputer and the Kaspersky ICS CERT Q3 2025 incident overview also described efforts to limit supply-chain effects and the possibility of product shortages. Neither account quantified realized shortages or established effects on consumer availability.

Was customer data stolen?
Bridgestone said it did not believe customer data or interfaces had been compromised. That was the company’s assessment while forensic analysis remained ongoing, not a final independently verified finding. The available contemporaneous account does not establish that customer data was stolen.
Was the Bridgestone incident ransomware?
The September 4 report said Bridgestone had not clarified whether the incident involved ransomware, and no group had claimed responsibility at that time. The incident should therefore not be described as confirmed ransomware or attributed to a named threat actor.

What is known about the timeline?
- September 2, 2025: Reports surfaced of a cybersecurity incident affecting two Bridgestone Americas production facilities in Aiken County, South Carolina.
- September 3, 2025: Canadian reporting described similar disruption at the Joliette, Quebec, facility.
- September 4, 2025: Bridgestone Americas confirmed it was investigating a limited cyber incident. The company said containment had occurred early, while forensic analysis continued.
The incident was reported in 2025. A later incident-tracking page carries a September 2026 label and describes recovery, but it conflicts with the contemporaneous chronology and is not a Bridgestone statement; it does not establish a verified recovery timeline.

The reported impact was operational disruption at manufacturing sites. That is distinct from data compromise: Bridgestone’s early assessment was that customer data and interfaces were not compromised. The contemporaneous report did not provide a quantified production-loss or downtime figure, confirm a ransomware attack, or establish the full set of affected facilities. Bridgestone Americas’ scale—50 production facilities and 55,000 employees—was reported by BleepingComputer as company figures, not as a measure of incident impact.
