The Japan Time is reporting that the names of 10,000 Japanese convicts have been leaked from an employee's personal computer that was infected by a virus from the P2P program Winny.
The information was initially stored on a CD by a staff member at Kagoshima Prison and handed to a staff member of Kyoto Prison in December.
That employee left the CD in a personal computer. The data was leaked after the computer was infected with a virus via the peer-to-peer file-sharing program Winny, which had been installed on the computer, the officials said.From The Japan Times Online - Advanced Search -

The only way for an enterprise to secure data is to make sure it's only kept in an authroized location. Once it's on an uncontrolled CD or even a laptop or PDA, you might as well assume that it's leaked.
