Japanese tyre manufacturer Bridgestone on Friday said its US subsidiary has suffered a ransomware attack, just weeks after suppliers of automaker Toyota Motor reported similar attacks.
The company in a statement said third-party unauthorised access was made at Bridgestone Americas on February 27, prompting it to shut down its computer network.
Bridgestone said it later reconnected the network after a comprehensive security check. An investigation later determined the incident to be a ransomware attack.
The announcement comes about two weeks after Toyota’s main supplier, Denso, detected unauthorised access via a ransomware attack at a group company that handles sales and engineering in Germany.
Another Toyota supplier was hit by a cyberattack late last month, prompting Japan’s largest automaker to shut down domestic production for one day on March 1, affecting output of about 13,000 vehicles.
On Monday, Bridgestone suspended Russian local manufacturing and exports to Russia in the wake of Moscow’s invasion of Ukraine.
The company said it suspended its passenger car tyre plant operation and froze all new capital investment.
