nChroma Bio Listed by Coinbase Cartel Ransomware Group

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

nChroma Bio 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.

nChroma Bio Listed by Coinbase Cartel Ransomware Group

On March 15, 2026, biotechnology company nChroma Bio appeared on the leak site of the coinbasecartel ransomware group. The listing indicates that internal files were exfiltrated during a ransomware attack on the company, which specializes in metabolomics and synthetic biology. While the exact number of individuals affected remains unknown, any personal data contained in those files now sits on a dark-web marketplace where criminals routinely sell or publish it.

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 nChroma Bio was listed on the coinbasecartel leak site on March 15, 2026. The data consists of internal files exfiltrated in a ransomware incident. No confirmed victim count has been published, and the precise types of records exposed—such as employee names, customer information, research data, or financial details—have not been independently verified beyond the group’s own claims. The primary source remains the coinbasecartel leak page itself, mirrored on ransomware tracking platforms.

Why This Matters for You and Your Family

When a company like nChroma Bio suffers a breach, the information inside its files can include details that point straight back to ordinary people. Employees, contractors, research partners, or even customers may find their names, addresses, dates of birth, Social Security numbers, or contact information exposed. Once that data reaches criminal marketplaces, it can be used for identity theft, tax fraud, or phishing campaigns aimed at you and your family. Even if you have never heard of nChroma Bio, stolen credentials or personal records often surface in follow-on attacks that feel personal and immediate.

The Doxxing and Identity-Chain Risks

Exfiltrated internal files frequently contain more than isolated records. They can link email addresses to internal usernames, phone numbers, project notes, or even family references. Attackers stitch these fragments together into an identity chain that reveals far more than any single breach suggests. A work email leads to a personal account; a shared address uncovers children’s names or gaming handles. These chains accelerate doxxing, account takeovers, and targeted harassment. Credential leaks like this one regularly cascade into gaming account compromises because the same passwords or recovery details are reused across work, personal, and entertainment platforms.

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.
