Pretty much anyone who’s been paying any attention knows that the big record
labels are trying to prevent people from copying CDs (and anyone who really
cares already knows that the methods used by the labels are easy to get
around). Most recent ones install software on your computer (usually only on
Windows) and only allows you to play the music through their software (denying
Americans of their “fair use” rights). The software installed by
Sony actually compromises your computer’s security.

Mark Russinovich discovered a rootkit on
his system; further analysis revealed that it was installed by a CD published
by Sony. The rootkit, among other things, hides files whose names start with
$sys$, and apparently, trying to remove the rootkit, or other parts of the
software that they install, kills Windows. In response, Sony releases a
service pack that claims to remove the software, and claims that the rootkit
does not pose any security threat. (But any software that is able to hide files
from the system is an open door to malicious use.) However, despite claiming
that the service pack removes the software, it simply
installs a newer version
that has the $sys$-masking disabled.
(The Inquirer,
Freedom to Tinker,
/.)
The whole thing has resulted in
lawsuits from California
(/.)
and Italy,
and an
investigation from the Italian police.
And despite Sony’s claims that the software poses no threat, a trojan has been
discovered that
uses Sony’s rootkit to hide itself.
(/.)
And their service pack for uninstalling the rootkit opens up another security
hole. First of all, in order to obtain the service pack (which Sony seems to
intentionally make it hard for customers to do), you must install an ActiveX
control, which
gathers information about your hardware,
which has serious privacy implications. Next, it turns out that the ActiveX
control actually
allows any webpage that you visit to install and run any code it wants.
(Washington Post,
Schneier,
/.) It sounds like
the cure is worse than the disease. Fortunately, some people have written a
tool that
secures your computer against the software.
Finally, Sony decided to
stop production of CDs with the rootkit,
(
/.)
and pulled it from store shelves
and offer exchanges to anyone who bought a CD with the rootkit on it.
(
/.)
This happened two weeks after the rootkit was initially discovered. And Sony
has still offered no way to properly remove the rootkit if you already have it
installed.
Sony has been
criticized by the Department of Homeland Security,
and Microsoft, who have said that they
will remove the rootkit.
It has also appears that Sony’s software may also
infringe on
other
people’s
copyright.
(/.,
/.) Oh, the irony of
infringing on other peoples’ copyright in an effort to protect your own.
Freedom to Tinker has instructions on
how to remove Sony’s software. But
to play it safe, it’s probably a good idea to stop buying CDs from Sony,
because you never know what they’re going to try to pull in the future. In
fact, it’s probably best to stop buying Sony products at all.

more detailed column in Wired.
And remember, the next time you put an audio CD in your Windows machine, hold
down the Shift button. That will prevent software from being automatically run
on your computer. Then you can use a program like
CDex to copy the music onto your computer and
listen to it at will.
