Looks like open source disk encryption software TrueCrypt has shown its mettle in a cybercrime case out of Brazil. The Brazilian police seized 500 TrueCrypt protected drives from the apartment of Daniel Dantas, a Rio banker accused of financial crimes. In Brazil, there is no law compelling defendants to reveal passwords to encrypted evidence, so the Brazilian crime lab attempted to break the encryption for five months with no success. They then turned to the US FBI, who ran dictionary attacks against the encryption for another year. No joy. As a result of the bankerís good password practices, the 500 drives with potential evidence were reduced to really ugly paperweights.
