His results are pretty scary, but what is even more scary is what the government has decided to do in response (google translated):
"But the fact is that the partial reports indicate so many vulnerabilities in the system, ranging from Generation of Media to writing data to floppy disk, the TSE (brazilian government agency) has decided to: 1) keep the reports secret to completely prevent voters to know that the Brazilian system has vulnerabilities , 2) prevent the penetration tests requested in 2006 by political parties, 3) abandon the current project for electronic ballot boxes after the elections of 2008, 4) to extend the contract with FACTA/CenPRA to try to develop a new project of electronic ballot boxes more reliable for the elections of 2010 and 5) to misinform the voters, in public denying the existence of security holes, saying that tests of penetration will be allowed in 2008."
