On September 12, 2024, CSMR Agrupación de Colaboración Empresaria appeared on the leak site operated by the meow Ransomware Group.

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 meow Ransomware Group’s onion site, accessible via ransomware.live mirrors, lists CSMR as a victim and claims successful data exfiltration. No sample files have been published in the current listing, and the group has not publicly stated a ransom demand or deadline. The notification simply confirms that internal files were allegedly exfiltrated after the organization’s systems were compromised. CSMR has not yet issued its own public breach notification, so the precise scope remains unknown to outsiders.

Why This Matters for You and Your Family

When a business association like CSMR suffers a breach, the ripple effects reach ordinary people. Member companies, suppliers, employees, and their families often have personal information stored in shared directories, contracts, invoices, or HR files. If your employer or a company you work with participates in CSMR’s collaborative projects, your name, contact details, tax identifiers, or banking information could be among the stolen material. Even without exact victim counts, the exposure creates immediate identity risk for anyone whose data touched the organization’s systems.

Doxxing and Identity-Chain Risks

Exfiltrated internal files frequently contain spreadsheets that link employee names to personal email addresses, phone numbers, home addresses, and sometimes family member details. Attackers and subsequent data resellers can chain this information with usernames found in other breaches, turning a single corporate leak into long-term doxxing exposure. Credential leaks like this one often cascade into account takeovers on personal email, banking portals, and especially gaming accounts belonging to you or your children. Once a gamer tag is linked to a real identity and address, harassment, swatting, and financial fraud become realistic threats.

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.
