IT Hub says Sony’s DRM Rootkit Comes in Mac Flavor, Too:
Imogen Heap’s new CD, “Speak for Yourself,” on RCA Victor (a BMG subsidiary), has an extra partition for “enhanced” content. Along with Windows files, there is a Mac file present called “Start.app.”
When run, a EULA is first displayed (which does inform the user that software is going to be installed without saying exactly what that software will do).

The user then is prompted by the program for a user name and password. After that information is provided, the program seemingly quits. However, it actually installs two kernel extensions, PhoenixNub1.kext and PhoenixNub12.kext, in the OS X system files.
These turn out to be part of a DRM codebase developed by SunnComm.
Will someone please tell me when the last cockroach crawls out from under Sony’s big mess?

Windows is nearly unique. Most operating systems (including Mac’s OS X) can not execute software on a CD automatically. The audio tracks are still available for playing via other software. DRM software can’t get a good foothold on the computer unless the user explicitly puts it there.
Frankly, the autorun feature on Windows should be disabled. It is incredibly dangerous. One can never be too sure just what you may find on a CD these days –even those distributed by major companies.
