■ AI-SUMMARIZED FROM 1 SOURCE ▸ TIMELINE

Hackers defaced the Seiko USA website over the weekend and claim to have stolen its Shopify customer database. The attackers are demanding a ransom, threatening to leak the data publicly.

The compromise affected Seiko's e-commerce platform, with the defacement serving as proof of the breach. The attackers posted a message on the site stating they obtained customer information from the retailer's Shopify database. No specific details have been disclosed about the number of affected customers or what data was accessed. Seiko has not yet released an official statement regarding the incident, response timeline, or whether authorities have been notified. Shopify-based retailers have faced increased targeting from cybercriminals in recent years. The breach represents another case of attackers leveraging stolen customer databases for extortion purposes rather than immediate public release. Customers who made purchases through Seiko USA should monitor their accounts for suspicious activity and consider placing fraud alerts with credit bureaus if they provided financial information.
