— from Coinbase Cartel’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

[Removed] #1534 Listed by Coinbase Cartel Ransomware Group

On September 15, 2025, the ransomware group CoinbaseCartel listed victim number #1534 on its leak site under the title “[Removed] #1534,” exposing internal files stolen during a ransomware attack. The company behind the victim identifier immediately requested removal and denied that any breach had occurred.

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 on the ransomware.live portal shows the listing appeared on September 15, 2025. The entry states that internal files were exfiltrated. The victim identifier was later removed at the company’s request through ticket #1534. No confirmed count of affected individuals has been published, and the precise systems compromised remain undisclosed in available reporting. The group’s leak page described the data as proof of a successful ransomware deployment, though the targeted organization maintains no breach took place.

Why This Matters for You and Your Family

When internal files leave a company’s control, the information inside can include customer records, employee details, contracts, or spreadsheets that contain names, addresses, phone numbers, and email accounts. Even if the company denies a breach, once data reaches a ransomware leak site it can be downloaded by anyone. For ordinary families this means yesterday’s routine business interaction can become tomorrow’s source of spam, identity theft, or targeted scams. Children’s names or school-related details sometimes appear in such files, creating long-term risks that parents must address directly.

The Doxxing and Identity-Chain Implications

Stolen internal files frequently contain enough fragments to link an email address to a username, a phone number to a family address, or a customer ID to social-media handles. Attackers then chain these pieces together across dozens of other breaches. A credential found in one leak can unlock a gaming account, which in turn reveals chat logs or linked payment methods. Public reporting indicates these doxxing chains often begin with exactly the kind of corporate data that appeared in this incident. The result can be harassment, account takeovers, or extortion attempts aimed at you or your children.

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.
