Attack Shuts Down Production at Lens Maker Hoya

INCIDENT

Production of several of Hoya Corp.’s products shut down after a system failure, which was most likely the result of “unauthorized access” to its servers, company officials said Thursday.
Japanese lens maker Hoya said the company discovered a system discrepancy in one of its overseas offices Saturday and confirmed the disruption despite its efforts to isolate affected servers.
“The day before yesterday (March 30), we learned that the Group’s head quarter and several of its business divisions have experienced an IT system incident,” the company said in a statement they issued Monday. “The Company will work closely with each of its business divisions and sites, as well as with outside experts, to identify the nature and scope of the incident and to restore the situation as soon as possible.”
