Plug Power Listed by Coinbase Cartel Ransomware Group

If you are a customer of Plug Power, here’s what is being claimed, and what it would mean for you.

Plug Power was listed on Coinbase Cartel's leak site. Coinbase Cartel claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Plug Power Listed by Coinbase Cartel Ransomware Group

On September 15, 2025, Plug Power appeared on the leak site of the coinbasecartel ransomware group. The company, a major supplier of hydrogen fuel cell technology, may have had internal files stolen during a ransomware attack. While the exact number of people whose information may have been exposed remains unknown, any Plug Power customer, employee, vendor, or partner whose personal or corporate details were stored in those systems could be affected.

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.

What Public Reporting Shows

Public reporting indicates that coinbasecartel exfiltrated internal files from Plug Power before encrypting systems or demanding payment. The data was later published on the group’s dark-web leak site, accessible via the .onion link hosted on ransomware.live. No confirmed total of records or specific victim count has been released by the company or the attackers. Available reporting describes the incident as a classic ransomware operation involving both encryption and data theft for extortion.

September 15, 2025 marks the date the listing went live. The exposed material consists of internal files rather than a single database dump, which often means a mix of employee records, customer contracts, vendor information, and operational spreadsheets may be circulating.

Why This Matters for You and Your Family

When a company like Plug Power suffers a breach, the ripple effects reach ordinary people. If you have ever purchased hydrogen fuel cells, worked with the company, received service from a partner, or had your information stored in a vendor system, your data may now be in the hands of criminals. This includes names, addresses, phone numbers, email accounts, and any financial details tied to transactions.

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.
