Messages exchanged on December 12, 2024 indicate that Daniel Vorcaro, former owner of the Brazilian investment bank Banco Master, ordered two international yellow fever vaccination certificates with a backdated application date. According to a report by Folha de S.Paulo published on Saturday, the conversations, obtained by the newspaper, took place with Luiz Phillipi Machado de Moraes Mourão, known as Sicário (a nickname meaning "hitman"), whom federal police identified as the head of the banker's private militia. In the exchange, Vorcaro sent personal data of actress Monique Alfradique and received two certificates logging an injection on April 9, 2024.

The exchange ran from 8:57 a.m. to 1:30 p.m., Folha reports. At 8:57, Vorcaro sent Sicário a vaccination certificate and wrote that he needed two certificates like that one. Around noon, Sicário relayed a message from an unidentified contact saying the job was ready and asking whether to insert it into the government system. He then asked for the woman's taxpayer ID number, promising to send everything "ready and solved". Vorcaro replied with the actress's full name, CPF number and date of birth.

At 1:25 p.m., the contact, in messages passed on by Sicário, said he had logged a dose as applied on April 9, 2024, and that the RNDS, the National Health Data Network that generates certificate PDFs in Brazil's public health system (SUS), was processing the record. Sicário sent a link to Meu SUS Digital, the federal government's health app, said the entry should already appear in the digital vaccination wallet, offered further help and delivered two certificates to Vorcaro.

In a statement, Alfradique's press office said her two yellow fever doses were administered "in an absolutely regular manner, at duly accredited health posts, in accordance with official protocols", the latest on April 22, 2024, at Fiocruz. Folha notes that it is unclear whether the actress knew of the request. The Health Ministry said SUS records rely on "security mechanisms, access controls and traceability" and that "there is no record of these mechanisms being compromised". Vorcaro's lawyers did not respond to the newspaper.

Timeline of the case

• December 2024: the messages about the certificates are exchanged on December 12.
• November 2025: Vorcaro is arrested for the first time in the Master scandal.
• March 4, 2026: Sicário is arrested on the order of Supreme Court Justice André Mendonça in the third phase of Operação Compliance Zero, the federal police probe into Banco Master. He later killed himself in a federal police lockup in Minas Gerais state.
• June 2026: Folha reported that messages on Vorcaro's phone showed he told Sicário to "moer" (Brazilian slang for beating) an employee of the actress; her office said she knew of no threat.
• September 2026: a federal police report on Vorcaro's phone is made public by Mendonça on September 1; the full court begins reviewing it on September 15, when Justice Flávio Dino suspended the debate with a request for more time.

Investigators described Sicário as the head of the "Turma", a group that, according to federal police, obtained confidential information for Vorcaro and threatened his opponents. Documents from the banker's phone were sent to the congressional inquiry into INSS, Brazil's federal pension agency, in which a contact of the actress was registered under the name "Alan TI", Folha reported. The case echoes the investigation into former president Jair Bolsonaro over an allegedly fake Covid-19 vaccination certificate: federal police indicted him in 2024 for inserting false data, but the attorney general's office asked for the case to be shelved in 2025, saying there were no grounds to hold him responsible.

The Master investigation sits before the Supreme Federal Court (STF) under Justice Mendonça. Attorney General Paulo Gonet, cited in the police report, argues the document is void because it was produced without a prior request from his office or the police and without authorization from the full court. The plenary debate, which began on Tuesday (15), was interrupted by Dino's request and has no date set to resume. Vorcaro is under investigation and remains presumed innocent.
