The Sony XCP rootkit story just keeps getting better and better – copyright infringement lawsuits may soon be added to the antitrust and computer hacking ones. Matti Nikki has disassembled it and found out that it uses code from several opensource projects – including LAME (the popular MP3 substitute codec used by the likes of Audacity) and VLC (the cross-platform media player written by John Lech Johansen. Why is this a problem? Because both programs are licensed under the GPL license, which requires that ANY program incorporating code from them must itself be released under the GPL. So far, XCP has not been released under such a license. Sony has now been well and truly knocked off its cherished high horse.
