Regarding Unauthorized Access to Our Email Delivery Service
Nippon Paper Industries Co., Ltd.
We have become aware that an external service we use to distribute our investor relations-related email newsletter was subject to unauthorized access, resulting in the leakage of registered subscribers' email addresses.
We sincerely apologize for any inconvenience and concern this incident may have caused to those affected and all other concerned parties.
The information confirmed to date is as follows.
Background of the Incident
In order to distribute our IR-related email newsletters to individuals who have registered through our website, we use ‘arara message (auto-mail)’ (hereinafter referred to as the "Service"), an email distribution service provided by arara inc. through ‘XD.GROWTH’, an email distribution platform provided by Tribeck Inc.
On November 2, we were notified by Tribeck Inc. that the Service had been subject to unauthorized access by a third party, potentially resulting in the leakage of registered information. On November 4, it was confirmed that registered users' email addresses had been leaked.
Information Affected
1,359 email addresses of individuals who registered for our IR-related email newsletter through our website.
Impact on Our Operations
The Service is an external cloud-based platform that operates independently of our networks and systems. Consequently, this incident has had no impact on our networks, systems, or business operations.
Precautions
Although no secondary harm, such as unauthorized use of the leaked information, has been confirmed at this time, there is a possibility that suspicious emails from parties impersonating us or our affiliates may be sent using the information leaked in this incident.
If you receive any such suspicious emails, please exercise caution and refrain from clicking on links contained in such emails, opening attachments, or entering any personal information.
Future Actions
We are working with Tribeck to verify the information affected by this incident. If our investigation reveals any additional information that should be disclosed, we will promptly make it public.
We will individually contact those whose personal information has been identified as affected by the incident to explain the confirmed facts and provide guidance on precautions to help prevent further harm.
