Narumi (Thailand) Co.,Ltd. Listed by thegentlemen Ransomware Group

On August 19, 2025, Narumi (Thailand) Co., Ltd. appeared on the leak site of the ransomware group known as thegentlemen. The company, a Japanese-owned manufacturer of plastic automotive parts in Rayong, Thailand, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, anyone whose personal data was stored in the company’s systems — employees, suppliers, customers, or their families — may now be at risk.

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.

The Doxxing and Identity-Chain Implications

Ransomware operators rarely stop at dumping raw files. They map connections between corporate data and personal identities, linking work emails to home addresses, phone numbers to social-media accounts, and employee names to family members. This identity-chain process turns a single breach into a web of information that can be used for doxxing, harassment, or further extortion. Gaming accounts belonging to children are especially vulnerable because they often share the same household email or phone number listed in a parent’s employment records. A leaked work document can therefore expose a child’s username, leading to account takeovers, in-game harassment, or real-world contact.

Thegentlemen’s Publicly Known Track Record

Public reporting attributes the attack to the ransomware group thegentlemen. The group emerged in recent years and has targeted organizations across multiple sectors by gaining initial access through common vectors such as phishing or exploited remote desktop services, exfiltrating data before encrypting systems, and then pressuring victims through public leak sites. Their typical playbook combines data theft with the threat of release unless payment is made. While specific prior victims are still being catalogued by researchers, the group’s approach follows a pattern seen in many ransomware operations: steal first, encrypt second, and use the leaked data as leverage.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what this claimed breach may have exposed.
• Rotate any password used at Narumi (Thailand) or related automotive suppliers anywhere it has been reused, and switch to a hardware-backed authenticator app for 2FA instead of SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught in hours rather than months.
• Cover the entire household with DoxxScan family protection, which includes children’s gaming accounts that often chain back to the same address or parent email listed in employment records.
• Let remediation specialists handle takedown requests across data brokers and leak sites while you focus on securing your own accounts.
