A cyber attack on one of the world’s largest optics manufacturers has led to some of its servers to go offline, stunting production.
In a statement released on its site, Japan-based Hoya Optics said it suffered an “IT incident” that impacted some of its systems.
“The day before yesterday (March 29), we learned that the group’s headquarters and several of its business divisions have experienced an IT system incident,” the organisation said in a press release on 1 April 2024.
“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.”
Hoya added that while it did not have a timeline for the recovery of its systems, it would be contacting its customers directly with updates.
“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.
“As we make progress in restoring these systems, we will share updates with you,” it said.
While Hoya did not refer to a cyber attack directly in the press releases on its website, a PDF advisory discovered first by The Record, Hoya described an event that indicates the outage may have been caused by a cyber attack, saying that it was most likely that a third-party had accessed its systems.
“In the morning of March 30, 2024, we discovered a discrepancy in system behaviour at one of our overseas offices and confirmed that a system failure had occurred,” it said.
“We also engaged external forensic investigators who reported that this incident was most likely caused by unauthorised access to our servers by a third party.”
Hoya Optics said investigations are ongoing and is working to mitigate damage and impact on its customers.
“We are also investigating whether any confidential or personal information held by the company has been compromised or accessed by third parties, but the full analysis is expected to take a considerable number of days,” it stated.
The company said it would continue to follow its internal policies and local regulations based on its findings and engage outside cyber security authorities and experts.
The threat actor behind the Hoya Optics breach is currently unknown, with nobody yet to take responsibility for the attack.
Cyber Daily has reached out to Hoya for more information regarding the threat actor and will provide an update once more is known.
