What Public Reporting Shows
Public reporting indicates that Narumi (Thailand) Co., Ltd., a subsidiary of Narumi Goukin Manufacturing Co., Ltd. of Japan, was listed on the group’s leak site on August 19, 2025. The company employs roughly 130 people and supplies major automotive manufacturers including Mitsubishi Motors (Thailand), Honda Automobile (Thailand), and Hitachi Chemical Automotive Products (Thailand). Available reporting describes the incident as a ransomware attack in which internal files were allegedly exfiltrated. The precise volume and type of data stolen has not been fully detailed in public sources, but such attacks routinely include employee records, vendor contracts, correspondence, and other documents containing personal information.
Why This Matters for You and Your Family
When a manufacturer like Narumi is breached, the information exposed often reaches far beyond the factory floor. Payroll files, HR records, supplier contact lists, and customer details can contain names, addresses, phone numbers, email accounts, and government identifiers for employees and their families. Once that data leaves the company’s control, it can be sold, traded, or used to target you directly. For an ordinary family, this means higher risk of identity theft, phishing attacks, and unwanted contact that can feel deeply personal and hard to escape.
Credential leaks from corporate systems frequently cascade into personal accounts. If you or your family members used a work email or shared password for both job-related and home services, the exposure creates a direct path for attackers to move from corporate files into your daily life.
