Inside thegentlemen
thegentlemen operates as a ransomware group that maintains a leak site to publish victim names when negotiations fail.

About USTAR
USTAR is a Thailand-based company that develops and sells cosmetics and skincare products, including items for eyes, face, and lips. Organizations in this sector routinely maintain records related to product development, customer transactions, supplier contracts, and internal operations. A breach at such a firm can therefore involve both commercial information and data belonging to individuals who have interacted with the business.
What was likely exposed
The only data category named in connection with the incident is internal files exfiltrated during the ransomware attack. The precise contents of those files have not been disclosed. Companies of this type commonly store customer contact details, order histories, payment records, and employee information, yet the actual material removed in this case remains unconfirmed.
Why it matters
Exposure of internal files can lead to the misuse of business records or personal data that may have been stored alongside them. Individuals whose information appears in such files could face risks of targeted fraud or unwanted contact. For the organization, the incident may result in operational disruption, regulatory scrutiny, and costs associated with investigation and remediation.
What to do if you're exposed
Individuals concerned about possible exposure should begin by monitoring their financial accounts and credit reports for unusual activity. Changing passwords for any accounts linked to the organization and enabling multi-factor authentication where available are immediate practical steps. Readers can also run a free exposure scan of their email address against known breach data to check for appearances in public records of incidents.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
