Reported Details of the Breach

Public reporting indicates that Nathalin Group, founded in 1987 and formerly known as Buawaree Company Limited, was listed after a ransomware attack. The company operates tankers and provides logistics, international maritime, floating storage, and trading services across Thailand. Available reporting describes the exposed material as internal files that were allegedly exfiltrated during the incident. The exact number of records and the specific types of data contained in the leak remain unclear from current public sources.

The Gentlemen posted the listing on its dark-web leak site, accessible via the .onion address hosted on the ransomware.live tracker. As of the publication date, the group had not publicly specified a fixed extortion deadline, though its standard practice is to pressure victims with incremental data releases.

Why This Matters for You and Your Family

When a company like Nathalin Group suffers a breach, the information inside its files can easily include details that point back to ordinary people. Vendor records, employee rosters, customer contracts, or partner spreadsheets often contain names, addresses, phone numbers, email accounts, and sometimes dates of birth. Once those details leave the company’s control, they circulate on underground forums and become building blocks for identity theft, phishing campaigns, or harassment aimed at you or members of your household.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
