Brazil's Minister of the Supreme Federal Court (STF), Alexandre de Moraes, has taken significant steps to investigate an alleged leak of sensitive information concerning STF ministers and their relatives. He has ordered the lifting of bank secrecy for individuals under investigation, as authorities aim to uncover whether any of this confidential data was being sold illegally. In addition to financial data, Moraes has also mandated the access to telematics information, which encompasses emails, messages, and internet usage, to ascertain the communications and connections of the suspects.

On the operational side, the Federal Police executed four search and seizure warrants against public servants implicated in these serious allegations. These operations took place in major Brazilian cities, specifically São Paulo, Rio de Janeiro, and Bahia. The warrants were processed under the direction of the Attorney General's Office (PGR) and received the necessary judicial authorization from Moraes himself, highlighting the seriousness of the case and the cooperation between various legal entities in Brazil.

The investigation has thus far revealed four public servants, three from the Federal Revenue Service and one from Serpro, who are suspected of unlawfully disclosing tax secrecy protected information to unauthorized third parties. The development of this investigation indicates an intensified effort by Brazilian authorities to safeguard sensitive governmental data and potentially penalize those involved in the breach, while also shedding light on the vulnerabilities within public service data handling.
