A hacker has posted what appears to be private information of former president Luiz Inacio Lula da Silva on the Internet to protest a major corruption scandal which he says "will end in nothing."
The addresses of properties said to be owned by Silva, phone numbers, companies registered in his name and his taxpayer number were posted on Twitter. The hacker identified himself as nbdu1nder.
The trial surrounding a cash-for-votes corruption scheme saw 25 people convicted, including former top aides to Silva.
Silva has always denied any involvement and has not been charged in the case.
Silva's office would not confirm the authenticity of the information posted on Twitter and said it had no comment.
