The incident highlights the ongoing threat of cyberattacks and the importance of cybersecurity measures for businesses like Seiko USA. As hackers continue to evolve and find new ways to breach security systems, companies must stay vigilant and adapt their defenses accordingly.
Seiko's website was defaced on April 17, 2026, with hackers claiming to have stolen the company's Shopify customer database. The hackers demanded payment for the stolen data and threatened to publish it unless their demands were met. The stolen data includes customer information, order history, shipping data, and account details. Seiko USA has not publicly confirmed or responded to this incident, but the company has a history of being proactive when it comes to cybersecurity.
Seiko, a well-known Japanese watchmaker, has suffered a significant cybersecurity breach as its website was defaced over the weekend. The incident, which took place on April 17, 2026, has left customers and fans of the brand in an uproar as hackers claimed to have stolen the company's Shopify customer database.
The hacking group, who demanded payment for the stolen data, displayed a message on the Seiko USA website that read: "This is an urgent security notification regarding your Shopify store. Your customer database has been compromised." The message further warned that the attackers had successfully breached the company's Shopify backend and downloaded the entire customer database.
The stolen data, according to the hackers, includes the following information:
* Customer Information: Names, email addresses, phone numbers
* Order History: Purchase records, transaction details
* Shipping Data: Addresses, shipping preferences
* Account Details: Account creation dates, customer notes
In a brazen move, the hackers instructed Seiko USA to locate a specific customer account, identified as ID 8069776801871, within the Shopify admin panel. They also provided an email address that should be used to initiate negotiations.
The hackers gave Seiko USA just 72 hours to respond or face the consequences. They threatened to publish the stolen data unless their demands were met.
However, it is not yet clear what threat actor was behind this attack and whether their claims are legitimate. BleepingComputer has reached out to Seiko USA for further information but received no response.
Meanwhile, BleepingComputer has learned that the company has since removed the extortion message from its website.

Seiko USA has not publicly confirmed or responded to this incident, but the company has a history of being proactive when it comes to cybersecurity.
In conclusion, Seiko's website was defaced over the weekend with hackers claiming customer data theft and demanding ransom. The stolen data includes customer information, order history, shipping data, and account details.
