Ceres Listed by The Gentlemen Ransomware Group

On September 9, 2025, the Uruguayan think tank CERES appeared on the leak site of the ransomware group known as thegentlemen. The organization, whose full name is Centro de Estudios de la Realidad Económica y Social, is claimed to have had internal files exfiltrated during a ransomware attack on its networks, including www.ceres-uy.org and ceres.uy. Public reporting indicates that the data includes documents that could expose staff, researchers, donors, and partners.

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

Available reporting describes the incident as a classic ransomware operation in which the attackers gained access, exfiltrated files, and later listed CERES on their public leak portal. The primary source is the group’s own onion site, mirrored by ransomware.live. No exact victim count has been published, and the precise volume or sensitivity of the stolen files remains unclear from public information. What is certain is that internal files were taken and are now being used as leverage. The listing appeared on September 9, 2025, giving the organization a limited window before further publication.

Why This Matters for You and Your Family

Even though CERES is a policy research center, ordinary people are routinely affected when organizations they interact with are breached. If you or any member of your family has corresponded with CERES, attended one of its events, subscribed to its publications, or been mentioned in its research, your name, email address, phone number, or other personal details may now sit in a ransomware leak folder. Once that information reaches public forums or data-broker lists, it can be bought and used for identity theft, phishing, or harassment. Your family’s privacy is only as strong as the weakest organization that holds information about you.

The Doxxing and Identity-Chain Implications

Ransomware groups rarely stop at one dataset. A single leaked email can be cross-referenced with gaming usernames, social-media handles, and family addresses to build a complete profile. Public reporting shows that credential leaks of this type frequently cascade into account takeovers on personal services, including children’s gaming accounts that often reuse the same passwords or recovery emails as adult accounts. The result is a doxxing chain that can expose home addresses, children’s names, and daily routines. What begins as an institutional breach quickly becomes a personal one.

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.
