hi,

I this this has to be one of the most coherent emails on this subject,
and i agree 100% with this post an previous posts in this thread. (i
have had a few beers so in reality it might be more like 98%)

anyway i digress,

My point is/was,

This whole backlash has come about because a home music listener, who
is computer smart (sorry i dont know enough about you to give you more
props) installed a cd that was *bought from a shop*  in 2005 and had
this issue (XCP2)

I think that this rookit shit has been going on since 2002.

What i read from that website(first 4) was that sony have been using
XCP1 since 2002 on prerelease stuff. Whilst 99% of the population will
never own these versions, they will hear them on the radio, before
they get to the shops.
I want to know if the pre release stuff has teh same issue. (because
press and radio stations have been getting these for 3 years!)

whilst your (that is not you spesifcally bkfsec) are rught i think you
missed my point.

The trust thing is paramount in this.  I should not have to educate
these people not to play CD's from Sont, EMI, etc. they should be
safe. end of. no arguments.... not everyone can be security savvy, it
all most of my friends can do to be web savvy...

beer is getting hte better of me now, so i best go

cheers then

S.

I recommend everyone to get into this habit when using Windows desktops.


In cases in which you need admin privileges to install an application you
can just use the command "run as" by right-clicking on the executable to
install.

Ditto to all of this. It's not just good practice, it specifically stops the
XCP software which reports that it (actually, it says that the music player)
requires administrator privileges to install. I'm sure most people would
just login as admin and install, but at least at that point you're
explicitly pointing the gun at your own head and pulling the trigger.



I agree with the general points about using non-privileged users and as
well for disabling auto-run.  However, I think that you made the right
point by saying that "most people would just login as admin and
install", but I think that this thinking may represent a problem for the
information technology industry and security.

The problem, of course, is normal users.  Yes, security professionals
have gotten hit with this.  But most security professionals are pretty
savvy when it comes to operating their PCs.  For the most part, I'm not
too concerned with what we do.  And we're the only ones who will
actually, unfortunately, be helped by these suggestions.

Most normal users will still double-click on the CD to execute the content.

Most normal users will still happily run as admin in order to execute
the installer.

Trust is the issue in this situation.  People trusted Sony, and Sony
violated that trust.  Unfortunately, there are no easy solutions.  As
long as people are allowed to execute random code on their own
computers, trust will continue to trip people up.  I'm not sure that
there is an easy answer to this.  But those of us who are security savvy
should begin thinking about what our answers will do for the average
user.  The advice given here is a step in the right direction, but I
don't personally believe that it will end the flood of malware and the
like out there.  I think that the people cracking systems and installing
crap like XCP are going to continue doing it, knowing full well that
trust is their ally.

So what is the solution?  I don't know really... it's a tough nut to
crack.  Education works well, but what do we say in this case?  Say
"Trust no one because large corporations will screw you as badly as
everyone else?"

Thanks Sony - you really made our jobs easier here.  /sarcasm

And what about the vaunted end goal of hardware-based DRM?  Restriction
of what can be installed on a person's system.  I'm not comfortable with
that either... first of all because we all know that it won't take
people long to find a way around it and those people illegally
distributing malware could care less about violating the DMCA.  Second
of all because something like that won't stop companies from installing
crap like XCP.  And third of all because it reduces the ability for
people to control their own environments, making crap like XCP harder
for people to remove (which is a wholesale loss for the consumer).

So what's the permanent fix here?  I don't know... I think I, as well as
everyone else, am open to new ideas.   I think that we, as an industry,
need to very seriously think about what the safest method of installing
and auditing new code is.  The best thing I can think of at the moment
is an OS-defined new-code sandbox that can't access anything else until
approved... but that's only a start, and is still somewhat subjected to
the trust factor.
