From the beginning, Toyota stated that the attack did not appear to be a cyber attack, but has now clarified that the cause was a lack of disk space.

According to Toyota's report, on August 27, 2023, when regular maintenance work was carried out on the server that processes parts orders, there was insufficient space on the work disk used to delete and organize data in the database. , an error occurred during the work. Because the main server and backup were running on the same system, the backup also stopped due to a similar error, and the entire factory was forced to stop.

Toyota reports that they were able to identify the cause of the problem through repeated testing, and that the problem was resolved by moving the data to a server with larger capacity.

In addition, Bleeping Computer, an IT news site, revealed in May 2023 that due to a database configuration error at Toyota, customers' vehicle location information has been accessible to anyone for 10 years, and that Toyota's customer vehicle location information has been publicly accessible for 10 years, and that it has been uploaded to the app's API and supplier portal.
