Bridgestone Americas said it has restored connections between its facilities and its central computer network following a cyberattack earlier this month that disrupted its production operations.
The company, a subsidiary of Japan-based Bridgestone Corp., said the attack interrupted production at several of its North American and Latin American manufacturing and retreading facilities.
Bridgestone has begun to ramp up production at its affected facilities as part of its return to pre-hack output levels.
“With the safety and security of our systems being our top priority, we will continue to monitor for any signs of issues related to this limited cyber incident,” a Bridgestone Americas spokesperson told Cybersecurity Dive.
The company is continuing to investigate the hack with the help of third-party experts, and it is still working with federal law enforcement on the case.
Bridgestone has not yet revealed key details about the incident, including when it first detected the intrusion and what information, if any, the hackers accessed.
The company also has not yet disclosed the estimated financial impact of the attack or provided a full schedule for the restoration of its production capacity.
Bridgestone Americas says it has more than 50 facilities in the region and more than 55,000 employees.
The company previously told Cybersecurity Dive that it did not believe the hackers accessed customer data and that the damage was limited because employees were able to contain the incident relatively quickly.
The attack coincided with a major disruption at British automaker Jaguar Land Rover, an attack for which affiliates of the cybercrime group Scattered Spider claimed credit. Scattered Spider has historically focused on one industry at a time, with its attacks in recent months targeting the hospitality, retail, insurance and aviation sectors.
Jaguar Land Rover on Tuesday said it was extending a production pause until Sept. 24.
It remains unclear how hackers broke into Bridgestone Americas or whether any group has claimed credit for the intrusion.
Cyber criminals previously broke into the company’s networks in 2022 in what the company described as an “untargeted ransomware attack.”
