Usina Sao Jose Do Pinheiro Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Usina Sao Jose Do Pinheiro was listed by thegentlemen ransomware group on December 24, 2025, after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may have been affected; anyone connected to the organization should check whether their information was exposed and take appropriate protective steps.
Usina Sao Jose Do Pinheiro, a sugar mill operating in Laranjeiras, Sergipe State, Brazil, appears on a listing published by the ransomware group thegentlemen. The listing was reported on December 24, 2025, and states that internal files were exfiltrated during a ransomware attack. The number of individuals affected has not been disclosed.
The incident is significant because the organization supplies sugar, alcohol, molasses, and energy across the Brazilian Northeast and to selected markets in Europe and Africa. Any confirmed exposure of operational records would affect a long-established industrial site whose records date back nearly a century.
What happened
The only confirmed public information is the appearance of Usina Sao Jose Do Pinheiro on thegentlemen’s listing platform on December 24, 2025. No independent confirmation of the underlying intrusion, the date the files were taken, or the volume of data has been released. The group claims internal files were removed; further technical details remain undisclosed.
Who is thegentlemen?
Thegentlemen is a ransomware operator that maintains a public leak site where it lists organizations it asserts have been compromised. The group’s practice is to publish file samples or directory listings as evidence of access. In this instance the listing constitutes the group’s claim; no additional statements specific to Usina Sao Jose Do Pinheiro have been verified beyond the site entry itself.
About Usina Sao Jose Do Pinheiro
Usina Sao Jose Do Pinheiro traces its origins to the São José sugar mill founded in the region by Albano do Prado Pimentel Franco, with records appearing in an inventory dated 1928. The mill produces and commercializes sugar, alcohol, molasses, and generates energy. Its customer base includes buyers in the Brazilian Northeast as well as selected European and African markets. Organizations of this type routinely maintain records on suppliers, industrial processes, energy contracts, and personnel.
What data was at risk
The listing refers only to “internal files exfiltrated.” No inventory of file categories or record counts has been published.
- Internal operational documents were referenced in the listing
- Exact data categories and record volumes remain unconfirmed
- Personal data of employees, customers, or suppliers has not been specified
The real-world impact
Exposure of internal industrial and commercial files could reveal details of production volumes, contract terms, and energy-generation arrangements. Such information may be used by competitors or counterparties in future negotiations. For individuals whose records appear in those files, the primary risks are identity misuse or targeted fraud if personal identifiers are present. The organization faces potential operational disruption and the cost of restoring systems and reviewing access controls.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
