Maven Solutions Listed by Coinbase Cartel Ransomware Group

On December 12, 2025, the ransomware group known as CoinbaseCartel added Maven Solutions to its leak site and began publishing what it claims are the company’s internal files obtained during a ransomware attack.

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.

Reported Details of the Breach

Public reporting indicates that Maven Solutions, a provider of business software aimed at small shops and larger vertical markets, had internal files exfiltrated. The exact number of people whose information appears in the files remains unknown. Available reporting describes the exposed material as internal documents rather than a structured database of customer records. The group posted the listing and sample data on its onion-site leak page, a standard step in its extortion process before threatening wider publication.

Why This Matters for You and Your Family

When a company that handles business records or customer information is hit, the data eventually surfaces in places criminals search. Internal files often contain contracts, employee details, customer lists, or invoices that include names, addresses, emails, and sometimes payment information. If your name, email, or phone number is connected to Maven Solutions as a customer, vendor, or employee, that information can be combined with other leaks to build a profile attackers use against you. For ordinary families this means higher risk of phishing emails, identity theft attempts, or unwanted contact that feels personal and persistent.

The Doxxing and Identity-Chain Risks

Ransomware leaks like this one rarely stay isolated. Criminals treat leaked emails, usernames, and phone numbers as starting points for “doxxing chains.” A single address or handle found in Maven’s files can be cross-referenced with gaming accounts, social-media profiles, or older breaches. Once linked, attackers can hijack accounts, demand payment, or sell the full identity package on underground forums. Credential leaks of this type frequently cascade into account takeovers precisely because people reuse passwords across work, personal, and gaming services.

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.
