Ceres Listed by thegentlemen 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.

What's Publicly Reported from Reporting

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.

The Group’s Known Track Record

Public reporting attributes thegentlemen with emerging in recent years as a double-extortion ransomware operation. The group is known for targeting mid-sized organizations across multiple countries, exfiltrating data before encrypting systems, and then pressuring victims through both encryption and public shaming on their leak site. Notable prior victims have included various private companies and nonprofits, though exact details vary by report. Their typical playbook involves initial access through common vulnerabilities or phishing, followed by quiet exfiltration, deployment of ransomware, and finally setting payment deadlines while threatening to release stolen files. Readers can follow trackers that monitor thegentlemen for updates on their activity.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup to remove what you can.
• Rotate any password you ever used at CERES or similar research organizations anywhere it has been reused, and switch on 2FA through an authenticator app rather than text messages.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak that touches your family is caught in hours, not months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same addresses and recovery details.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing your own accounts.
