According to the news agency, the world's largest automaker is suspending production at a third of its factories. Toyota will temporarily stop making cars at its Japanese factories after one of its suppliers was hacked.

The company that makes parts for Toyota, both for car interiors and also for its hybrid and fuel cell electric vehicles, is called Kojima Industries. The event was described as a supplier system failure by a Toyota spokesman.

On March 1, Toyota will stop 28 production lines.

Toyota has become a frequent target for hackers. It was compromised at least three times in the year, including a hack of 3.1 million customers in Japan and a scam that cost a subsidiary $37 million.

Toyota was hacked again in 2021, this time via a US parts subsidiary, which is believed to be Russian.

It is not the only company to have to stop production after being compromised. We reported in 2020 that Honda had to stop making motorcycles in India and South America because of production problems.

There is no public information about the cyber attack today. Fumio Kishida, Japan's prime minister, said that his government would investigate any possible links to Russia.
