Brazil’s Eletrobras Says Nuclear Unit Hit with Cyberattack

RIO DE JANEIRO, BRAZIL – A nuclear power subsidiary of Brazil’s Eletrobras suffered a cyberattack but no operations were impacted, the state-controlled power holding company said in a filing late on Wednesday, February 3rd.

The network that was attacked by ransomware is not related to the operational systems of nuclear energy plants Angra 1 and Angra 2, said Centrais Eletricas Brasileiras, as Eletrobras is formally known.

Subsidiary Eletronuclear has suspended use of some of its administrative software to protect its data, the company said in the filing.

It said the incident is under investigation by government entities responsible for nuclear power security.
