Sony puts rootkits on CDs

[mdlbear]

Slashdot and BoingBoing both point to this article dissecting the rootkit that Sony installs in the name of DRM on their recent audio CDs. It hides registry entries and processes, and hooks into drivers and system calls, and creates a hidden directory. It's a rootkit -- one of the nastiest forms of malware out there.

It'll be a cold day in Hell the next time I buy a Sony product. Too bad for them; I was thinking of getting another pair of headphones. Anybody know of something roughly equivalent to the Sony MDR 7509's?
