# STJ Investigates Assets of Ex-Official Linked to Data Leak Scandal Court president confirms internal probe into former IT secretary accused of leaking confidential documents. - **Source:** [Estadão](https://www.estadao.com.br) - **Published:** 2026-11-12 - **Topic:** [politics](https://brifing.si/c/politics) - **Original article:** - **On Brifing:** https://brifing.si/s/b77cad26-9489-4203-8b2e-3a84e465485c ## Internal Probe Initiated Superior Tribunal de Justiça president Luis Felipe Salomão confirmed an internal investigation into the assets of Humberto Pradera. Pradera, a former court official, was arrested on Tuesday, December 10, following allegations of leaking classified information. The tribunal is currently conducting a confidential audit to determine the full extent of his financial activities. ## Unauthorized Data Disclosure Investigators suspect Pradera leaked sensitive court documents to lawyer Willer Tomaz. Evidence includes a photograph of a computer screen sent by Pradera to Tomaz, detailing the contents and potential legal impacts of a decision not yet signed by a minister. This breach compromises the integrity of ongoing judicial proceedings within the court. ## Career and Dismissal Humberto Pradera served at the STJ since 2018, holding various high-level positions. He previously acted as the chief advisor for the Artificial Intelligence office before becoming the secretary of information technology. Following the emergence of these allegations, he was officially exonerated from his role at the tribunal in October of this year. ## Broader Criminal Investigation The leak investigation is linked to a wider Federal Police inquiry involving Willer Tomaz and Flávio Bolsonaro. Both individuals are under investigation by the Supreme Federal Court for alleged money laundering. Authorities suspect they operated a hidden partnership to launder illicit funds through various betting houses, complicating the legal landscape significantly. ## International Legal Status Current reports indicate that Willer Tomaz is residing in the United States. Similarly, Flávio Bolsonaro traveled to the United States after Supreme Court Justice Alexandre de Moraes ordered the surrender of his passport. The Federal Police filed a formal representation regarding these movements on October 25, highlighting the international scope of proceedings. ## Judicial Integrity Concerns The case highlights critical vulnerabilities in judicial data security protocols. By leaking information before official signatures, the suspect potentially influenced legal outcomes or provided unfair advantages to external parties. The STJ is now reviewing its internal procedures to prevent similar breaches and ensure that sensitive information remains protected from unauthorized access. ## Financial Audit Scope Salomão emphasized that the investigation focuses on Pradera's patrimony and the specific procedures he utilized during his tenure. The court aims to uncover whether the suspect gained financial benefits from his illicit activities. This forensic accounting process remains under strict judicial seal to protect the integrity of the ongoing criminal investigation. ## Future Legal Implications The outcome of this probe will likely influence future security measures at the STJ. As the Federal Police continue their inquiry into money laundering and data leaks, the tribunal faces pressure to restore public trust. Observers are monitoring how the court balances internal accountability with the ongoing criminal proceedings against the suspects. ## Sources covering this story - https://www.estadao.com.br/politica/stj-apura-patrimonio-de-ex-servidor-preso-por-vazar-dados-a-willer-tomaz-diz-presidente-do-tribunal-nprp/ — --- _Summary written by Brifing from the original reporting.
