FAQs: Service Outages on IBIDEN's Website
Regarding the recent unauthorized access to our website, we sincerely apologize for the considerable concern caused to our customers and all other stakeholders.
In response to common inquiries regarding this matter, we would like to provide the following information.
Regarding Concerns about Information Leakage
Based on our investigations to date, we have not confirmed any damages, including the leakage of technical information or personal information. No damages have been confirmed other than the display of unauthorized web pages and the temporary suspension of access to the website.
Scope of Unauthorized Access
The recent unauthorized access was limited to our web server. We have not confirmed any unauthorized access to our CMS (Content Management System) for managing web content, other internal servers, or the cloud services we utilize. Therefore, there has been no impact on our internal systems or customer information.
Current Response and Future Outlook
Immediately following the incident, we suspended access to our website and have been proceeding with restoration efforts. While the website's display functionality has now been restored, we are continuing our investigations to identify the detailed unauthorized access route, elucidate the root cause, and strengthen our security measures. Once permanent countermeasures are completed and the final security and safety are confirmed, we will provide a further update through official public disclosures and our official X (formerly Twitter) account, among other channels.
We deeply regret causing concern to our customers. We will continue to prioritize security measures and exert our utmost efforts to prevent a recurrence. We kindly request your understanding and cooperation during this time.
