nedamaritime.gr Listed by Blackout Ransomware Group

On December 10, 2024, Greek shipping company Neda Maritime appeared on the leak site operated by the Blackout ransomware group. The listing states that internal files were exfiltrated during a ransomware attack on nedamaritime.gr. The company, which manages and operates vessels internationally, has not yet published a public breach notification, leaving the exact number of affected individuals and the full scope of exposed data unknown at this time.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Details from the Leak Site

The Blackout ransomware group’s onion site lists Neda Maritime as a victim and claims the company’s internal files were stolen prior to encryption. The disclosure indicates that data was exfiltrated but does not specify the volume of records, the precise systems compromised, or the categories of information involved. As of the publication date, the group had not posted any sample files. The listing does not quantify affected records or name specific data types such as customer records, employee payroll, or vessel manifests. Public reporting on Blackout indicates the group typically uses this initial posting to pressure victims before escalating to full data publication or extortion demands.

Why This Matters for You and Your Family

When a shipping company’s internal files are stolen, the information often includes details that can be traced back to individuals. Contracts, invoices, crew lists, medical certificates, or vendor databases frequently contain names, addresses, dates of birth, passport numbers, email addresses, and phone numbers. If your family has done business with Neda Maritime, traveled on one of their vessels, or if you or a relative has worked in the maritime industry, your personal information may now sit in an attacker-controlled archive. Even when exact victim counts remain undisclosed, the exposure creates long-term risk because once data leaves the company’s control, it can be traded or sold on underground forums for years.

December 10, 2024 marks the moment this particular dataset became a public extortion tool. Families rarely realize their data was caught in a corporate breach until identity theft or phishing attempts begin months later.

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.
