Mark Russinovich has discovered a rootkit on his computer that he believes is part of a DRM scheme for a Sony CD. Like your average malware, it's hidden, poorly written, difficult to get rid of. And according to Russinovich, the EULA says not a peep about it, meaning Sony didn't even bother with the usual pretense of giving people fair warning: "While I believe in the media industry’s right to use copy protection mechanisms to prevent illegal copying, I don’t think that we’ve found the right balance of fair use and copy protection, yet. This is a clear case of Sony taking DRM too far."
