Hoya Corp - Tokyo-based medical technology company focused on optics - Says an investigation into its recent IT incident has confirmed that the issue was caused by "a malicious party's cyber-attack". In early April, the company reported an IT incident, caused by unauthorized access to its servers by a third party, which disrupted and shutdown systems at the production plants of several divisions. Hoya says that the attacker exfiltrated a "limited number" of its files. The company has reported the matter to law enforcement, and engaged a data specialist to determine whether personal data has been affected. Hoya says its divisions will reach out to customers and business partners regarding any potential concerns related to the incident.

As of Tuesday, Hoya says that most divisions have restored their production and ordering systems, and that while certain divisions are still facing extended delivery times as they work through backorders, "the manufacturing and supply chain operations are largely returning to normal". Hoya says that the incident will have an "immaterial" impact on its business performance for the financial year ended March 31. The company intends to examine the impact on its upcoming business performance, and will disclose any relevant information once it becomes available.
