STJ created systems to reinforce security after suspected leak by former server

Humberto Fontoura Pradera, former secretary of Information Technology at the STJ, was the subject of an arrest warrant this Tuesday (10) on suspicion of having facilitated Willer Tomaz's improper access to information about cases being processed at the Court.

Before Tuesday's arrest order, Pradera had already been searched and seized on October 19, in the first phase of Operation Linceu.

Willer Tomaz and former presidential candidate Flávio Bolsonaro are being investigated in an inquiry at the Federal Supreme Court (STF) into alleged money laundering.

The investigation found on Willer's cell phone a photo sent by Pradera of a document that was still in production at the STJ.

In light of the episode, the court reinforced its security protocols, with changes to passwords and access, the adoption of double authentication and new restrictions to prevent information leaks.

Internally, the STJ considered the case serious and ordered the adoption of new controls in the systems. The tools seek not only to increase security, but also to expand the ability to identify who accessed certain information and track any leaks. The model is internally called “auditable trust”.

The STJ also determined as a standard the preparation of an inventory of accesses, with records that allow information to be tracked. The mechanisms also include the identification of hidden texts and metadata, more resistant authentication and monitoring of data use.
