Sony at it again: DVD based rootkit

I hadn’t been actively looking for Sony DRM links since putting the Sony Boycott blog on pause, so this one came as a surprise: an advisory from F-Secure that a recent Sony DVD (the apparently not completely execrable Mr. and Mrs. Smith) has rootkit-like behavior. The DVD contains DRM from Settec, which is designed to hide itself on the hard disk of anyone who plays the DVD on a Windows computer.

F-Secure posted this back in February; I found it from a few blog links. The usual suspects never commented on this as far as I know—perhaps because the DVD in question was only released in Germany.

Still. This is Not Good.
