Toyota has reportedly halted vehicle production at all of its plants in Japan following a cyberattack on a major supplier. Nikkei has called. “Due to a system failure at a domestic supplier (Kojima Industries Corporation), we have decided to suspend operations of 28 lines at 14 plants in Japan on Tuesday, March 1,” Toyota wrote on its global website.
Kojima supplies both exterior and interior parts, including components used in the air conditioning and steering wheel. The parts were unaffected, but Kojima was reportedly unable to communicate with Toyota or oversee production. The problem affected Toyota’s “just-in-time” manufacturing system, which requires parts to be delivered just before they are installed, so they don’t have to be stored.
Toyota did not mention a cyber attack on its website, but Kojima confirmed the issue. “It is true that we were hit by some kind of cyber attack. We are still confirming the damage and are rushing to respond, with the top priority being to resume Toyota’s production system as soon as possible,” a Kojima official said Nikkei.
Two other Toyota partners were reportedly hit, including truck maker Hino Motors and Daihatsu Motor. The origins of the cyber attack, the nature of the malware, and other details were not disclosed. Toyota hasn’t said when it expects to restart production lines, but the Japanese government is reportedly involved in the investigation.
