On Monday (16), the Chairman of the Superior Electoral Court (TSE), Luís Roberto Barroso, stated that he had requested the opening of an investigation into federal police to investigate the cyber attack targeting the Electoral Justice last Sunday. systems (15), characterized by the first round of municipal elections across the country.
The Denial of Service attack, also known as the DDoS attack, did not steal any data or affect electronic voting machines and election results. However, it resulted in an absurd slowness of remote TSE services across Brazil, thanks to requests from 435,000 connections – from countries like Brazil, the United States, and New Zealand.
In addition to this attack, the TSE president also called for an investigation into the leakage of old data, which was released this Sunday for convenience in an effort to delegitimize the integrity of the electronic ballot boxes and the entire electoral process.
He points out that the leak was made sometime in the past (without specifying the occasion) and noted that “as soon as they were leaked, digital militias immediately took action to discredit the system”. Without saying he had initiated concerted action, Barroso noted that there is a suspicion that it is an articulated movement of extremist groups seeking to discredit the institutions.
No influence on votes
As soon as there was news of the release of the old data and the denial of service attack, the coalition of media outlets with the TSE learned that there is no possibility of an external virtual attack on electronic voting machines. The equipment is not connected to the internet, both wired and wireless.
Since 1996, votes are recorded and counted from the digital voting register, removed from the machine after the voting period has expired and the ballot paper printed with the result of that ballot box. Shortly after it is deleted, it is sent to a private transmission pole, which then sends the data to the TSE.
The reception of data in the TSE system can even be affected by remote attacks; However, with any suspicion of external interference, authorities must recheck at the post and then the printed bulletin for each ballot box, minimizing the risk of interference with the results.
