There has been much discussion recently about Sony's rootkit that is bundled with some corrupted CDs. The EFF lists some of the corrupted CDs, and David Sklar suggests building a corrupt CD tracker (using Ning). There is already at least one exploit that takes advantage of Sony's new software.
It's nice to see that Computer Associates has stepped up and called this what it is - a trojan. (They also correctly label Sony's "Music Player" as spyware.)
