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 company has over 37,000 employees at 160 offices and subsidiaries in more than 30 countries and operates a network of 43 laboratories worldwide.
"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.
"At this time, we do not have a full restoration timeline for when our systems will be back online, but our priority is restoring our systems as quickly as possible, so we can continue to provide our customers with the highest level of service," the company added in a
separate advisory.
Hoya promptly responded to a server failure by isolating the affected servers and informing the relevant authorities in the impacted countries.
The optics company also hired outside forensic investigators who determined that the incident was most likely caused by a third party gaining unauthorized access to their servers, according to a new advisory [

The Record.
