TSE denies hacker attack after systems instability

Drop in systems was caused by internal overload

In a note released last night (12), the Supreme Electoral Court (TSE) denied that it had been the target of a cyber attack after some of its systems had suffered instability throughout the day.

According to the statement, the fall in systems „was motivated by an internal overload and has nothing to do with external interference (cyber attack)“.

On Thursday, the websites of the TSE and the regional courts were unavailable, as were the services of the Electronic Judicial Process (EJP), through which the parties can access documents from a case. The portal for the BitQT disclosure of applications also showed instability.

According to the TSE, the problem occurred due to a defect in a datacenter, equipment that stores and processes data. The court reported that technicians from the equipment manufacturer were working to correct the problem

The TSE assured that the technical problem does not affect the municipal elections, the first round of which is scheduled for next Sunday (15).

The fall in the TSE’s systems occurred just over a week after a cyber attack paralysed all the systems of the Superior Court of Justice (STJ). Other state bodies have also reported attacks recently, such as the Ministry of Health and the Federal District government.

Check out the full TSE note:

„The Superior Electoral Court clarifies that the fall in the systems of Electoral Justice, recorded on the afternoon of Thursday (12), was motivated by an internal overload and bears no relation to external interference (cyber attack).

Because of the problem, services such as the Electronic Judicial Process (Processo Judicial Eletrônico – PJE), dissemination of candidacies and websites of the TSE and regional courts were unavailable.

The blocking of infrastructure equipment, a datacenter, is being solved by court technicians in partnership with technicians from the manufacturer. Last night, the systems began to be standardized, and the expectation is to resume full on Friday (13).

The technical problem does not affect any process related to this Sunday’s vote (15), such as the preparation of ballot boxes, the counting of votes and the transmission of results.

It is important to remember that the Brazilian electronic ballot was designed to work without being connected to any network device, either cable, wifi or bluetooth. In other words, the ballot box is an isolated equipment, which preserves one of the basic security requirements of the system.

Besides that, the totaling of the votes, after the information is sent by the Regional Electoral Courts (TREs) works through a private encrypted network“.
