It turned out that a criminal group conducting a cyber attack with a ransom-based computer virus stole and disclosed confidential information of Toyota Group's major automobile parts maker "Denso" and made a statement on a dark site on the Internet.
"We are checking and investigating unauthorized access to the network at our base in Germany," Denso said.
According to the information security company "Mitsui Bussan Secure Direction", on the afternoon of the 13th of Japan time, a cybercrime group named "Pandora" was posted on a dark site on the dark web = Internet, a major Toyota group headquartered in Aichi prefecture. It turns out that it has issued a statement that it will steal and disclose confidential information of automobile parts manufacturer Denso.
According to it, there are more than 157,000 items such as purchase orders, emails, drawings, etc., and 1.4 terabytes of data.
"Pandora" uses ransomware, a ransomware-type computer virus, to perform cyber attacks that encrypt data such as companies so that they cannot be seen, and if the requested ransom is not paid, the stolen data will be released. It is said that he is committing a crime in a threatening manner.
"We are confirming unauthorized access to the network by a third party at a base in Germany. We are currently investigating the situation and whether there is any impact," Denso told NHK.
Regarding the cyber attack by ransomware, Toyota Motor's business partner "Kojima Industries" was damaged last month, and Toyota temporarily suspended all factories in Japan.
Denso is also Toyota's major customer, and there are a number of cases where automobile parts manufacturers are targeted.
