INCIDENT: Kojima Industries, a Toyota Supplier, Suffers Cyberattack

Toyota shut down production in Japan because Kojima Industries , one of its domestic suppliers, suffered a cyberattack. Kojima Industries provides plastic and other parts to Toyota.

Toyota employs a kanban "just-in-time" production method, so when Kojima was hit by ransomware which halted their key plastic and electronics parts production, Toyota chose to shutdown all 14 plants, and their network connections, to contain the spread. Toyota and subsidiaries were unable to keep their plants running. This is occurring amid ongoing parts and component shortages in the industry.

Toyota subsidiaries Hino Motors and Daihatsu Motor will also halt operations at some plants in Japan.
