Toyota reportedly halted vehicle production at all of its factories in Japan following a cyberattack on a major supplier, Nikkei reported. “Due to a system failure at a domestic supplier (Kojima Industries Corporation), we decided to suspend operation of 28 lines at 14 factories in Japan on Tuesday, March 1,” Toyota wrote on its global website.
Kojima supplies exterior and interior parts, including components used in its air conditioning system and steering wheel. Parts were unaffected, but Kojima was reportedly unable to communicate with Toyota or monitor production.

Toyota did not mention a cyberattack on its website, but Kojima confirmed the issue. “It is true that we have been hit by some sort of cyber attack. We are still confirming the damage and are rushing to respond, with the top priority of getting Toyota back into production as soon as possible,” an official said. by Kojima. Nikkei.
Two other Toyota partners were reportedly affected, including truck maker Hino Motors and Daihatsu Motor. The origins of the cyberattack, the type of malware and other details were not revealed. Toyota did not say when it plans to restart manufacturing lines, but the Japanese government is believed to be involved in the investigation.
