Centrais Eletricas Brasileiras (Eletrobras) and Companhia Paranaense de Energia (Copel), two major electric utilities companies in Brazil have announced that they suffered ransomware attacks over the past week.
State-controlled, both are key players in the country. Copel being the largest in the state of Paraná while Eletrobras is the largest power utility company in Latin America and also owns Eletronuclear, a subsidiary involved in the construction and operations of nuclear power plants.
