【Important】Suspicious e-mail occurring due to leakage of our email address and request for damage report

I would like to express my deep gratitude for your exceptional generous gifts.
We have confirmed that the email address owned by our company has been leaked due to an information leak that occurred on the external service "Udemy Business" (Benesse Corporation). As a result, it is predicted that suspicious emails (spam emails) spoofing our domain (@eleven-lab.co.jp) may be sent to third parties in the future.
*Udemy Business is currently canceling the service.

■ Current situation
Bot attacks based on leaked addresses have compromised forms on our website. Currently, as an emergency measure, we are gradually implementing system structure renewal and security measures (such as the introduction of reCAPTCHA v3) to block new unauthorized transmissions.

■ Request for damage report
In the unlikely event that you receive a suspicious email claiming to be our company or an email with unfamiliar content, please do not click on the link in the body of the email and delete it immediately.
In addition, if you have been harmed or contacted suspicious by an email that deceives our company, we apologize for the inconvenience, but we would appreciate it if you could report the details to the contact point below.
We will use it as a document for future legal responses and countermeasures.

■ About future measures
Although this case is caused by a management defect in an external service, we are considering strict action, including legal action, to protect the trust of the domain that we have maintained for more than 10 years.
We sincerely apologize for any concern and inconvenience this may cause.
