TOKYO (Reuters) - The cyberattack on a Toyota Motor Corp supplier that brought the automaker's domestic production to a halt shows how more vulnerable small firms can pose a big threat that Japan needs to do more to address, cybersecurity specialists said.

No information was available about who was behind the attack at supplier Kojima Industries Corp nor the motive, but it came just after Japan joined Western allies in clamping down on Russia after it invaded Ukraine. It was unclear if the attack was related.
