Important Notice regarding Data Breach and Response

The following corporate information was posted today, August 10, 2023, by Seiko Group Corporation.

Seiko Group Corporation (hereinafter referred to as “the Company” or “we”) has confirmed that on July 28th of this year, the Company suffered a possible data breach. It appears that some as-yet-unidentified party or parties gained unauthorized access to at least one of our servers. Subsequently, on August 2nd, we commissioned a team of external cybersecurity experts to investigate and assess the situation.
As a result, we are now reasonably certain that there was a breach and that some information stored by our Company and/or our Group companies may have been compromised.
Currently, we are verifying the exact nature of the information that was stored on the impacted servers. As soon as our ongoing investigation produces more specific results, we will report this immediately.
Working closely with cybersecurity experts, we are now making every effort to prevent further damage and to ensure that our systems are secure against any similar recurrence.
We deeply apologize to all concerned for any anxiety or inconvenience this may cause. The Company and all our Group companies kindly ask our customers and business partners to contact us immediately if you receive any suspicious or unusual emails or notifications from us.
If you do happen to receive any such questionable communications, please take extreme precautions to prevent your own systems from harm. Tell your staff to refrain from opening such mails if possible or, if they were opened by mistake, to avoid accessing any included links.
