Automotive hose maker Nichirin, headquartered in Japan, said that a U.S. subsidiary had been hit by a ransomware attack forcing it shut down its computerised production controls.
The U.S. unit, which supplies hoses to Japanese carmakers, has switched to manual production and shipping in order to keep parts flowing to customers.
“We are investigating what impact this may have on our customers, and we will promptly disclose any necessary information,” Nichirin said. Nichirin did not reveal the reasons for the cyber security issue. Also, Nichirin does not reveal its technology partners, who are responsible for its IT infrastructure in Japan and the US.
Nichirin also posted a warning on its website about possible spoof emails that appeared to be from the company and asked recipients not to open any attached files.
