Here's the important article. I've already written my congressman to
complain that involuntary installation ought to be illegal.

Removing Sony's CD 'rootkit' kills Windows
More fun with digital audio

Sysinternals' Mark Russinovich has performed an analysis of the copy
restriction measures deployed by Sony Music on its latest CDs: which he
bluntly calls a 'root kit'. Using conventional tools to remove Sony's
digital media malware will leave ordinary users with Windows systems
unable to play CDs.
While the Sony CDs play fine on Red Book audio devices such as standard
consumer electronics CD players, when they're played on a Windows PC the
software forces playback through a bundled media player, and restricts how
many digital copies can be made from Windows.
A 'root kit' generally refers to the nefarious malware used by hackers to
gain control of a system. A root kit has several characteristics: it finds
its way onto systems uninvited; endeavors to remain undetected; and then
may either intercept system library routines and reroute them to its own
routines, or replace system executables with its own, or both - all with
the intention of gaining system level ownership of the computer.
What makes Sony's CD digital media software particularly nasty is that
using expert tools for removing the parasite risks leaving you with a
Windows PC that's useless, and that requires a full reformat and reinstall.
So is Sony bundling a root kit, or is it the latest in a long line of
clumsy, and sometimes laughably inept attempts to thwart the playback of
digital media on PCs?
We were inclined to the latter - but in practical terms, for ordinary
users, the consequences are so serious that semantic distinctions are
secondary.
In actuality both, reckons Russinovich. It's a 'root kit' that arrived
uninvited, but it's also "underhanded and sloppy software" , that once
removed, prevented Windows from playing his CD again (Van Zant's 'Get With
The Man') he notes in his analysis.
The Sony CD creates a hidden directory and installs several of its own
device drivers, and then reroutes Windows systems calls to its own
routines. It intercepts kernel-level APIs, but then attempts to disguise
its presence, using a crude cloaking technique.
Disingenuously, the copy restriction binaries were labelled "Essential
System Tools".
But the most disturbing part of the tale came when Russinovich ran his
standard rootkit-removal tool on the post-Sony PC.
"Users that stumble across the cloaked files with a RKR scan will cripple
their computer if they attempt the obvious step of deleting the cloaked
files," he writes.
Which puts it in an entirely different class of software to the copy
restriction measures we've seen so far, which can be disabled by a Post-It
note. Until specialist tools arrive to disinfect PCs of this particular
measure. ®
