Hoya Corporation, one of the largest global manufacturers of optical products, says a “System failure” caused servers at some of its production plants and business divisions to go offline on Saturday.
“The day before yesterday, we learned that the Group’s head quarter and several of its business divisions have experienced an IT system incident,” Hoya said in a statement published on Monday.
Hoya promptly responded to a server failure by isolating the affected servers and informing the relevant authorities in the impacted countries.
As a direct result of this incident, some production plants and the ordering system for certain products have been impacted.
Hoya is currently investigating whether the hackers accessed or extracted any confidential or personal information stored on the compromised systems.
“We will continue to investigate and analyze the impact of this incident in cooperation with outside experts and relevant authorities, and will take measures to restore the systems necessary for production and sales activities and to resume the supply system of products to customers as soon as possible,” Hoya said.
