TOKYO (Reuters) -Japanese tyre manufacture Bridgestone Corp on Friday said its U.S. subsidiary had been hit by a ransomware attack, just weeks after suppliers of automaker Toyota Motor Corp reported similar attacks.

Bridgestone said third-party unauthorised access was made at Bridgestone Americas on Feb. 27, prompting it to shut down the computer network and production at its factories in North and Middle America for about a week.
