Well, here's an anecdote: at last year's CEAS conference, Rob Thomas
of Team Cymru gave the keynote on the underground economy, with a most
horrifying set of both live demos and selected snapshots of the online
bazaars where online warez are traded, everything from zombie farms to
spamware to stolen credit cards.  One of the more amusing was a guy
who offered a zombie in some part of the government that you'd hope
would be moderately secure, NASA or someplace like that, at a higher
than normal price.  The immediate response was ridicule, bots on
government nets are a dime a dozen, and aren't worth any more than any
other bot.


Oh, goodie. I get to the same source to show the opposite. At Rob's 
talk at the AOTA summit, he talked about someone offering some botted 
machines in a particular US government subnet at a normal prices and 
someone quickly over-bid by a suspiciously high amount. The 
assumption is that it was for the possible data on those machines.

2007-05-21 Thread dan


A while ago, I did a rough calculation that made
me state that 15-30% of all machines are no longer
under the sole control of their owner.  In the
intervening months, I got some hate mail on this,
but in those same intervening months Vint Cerf
said 40%, Microsoft said 2/3rds, and IDC said 3/4ths.

Whatever it is, it is  0.

And, of course, definitions matter.  I don't think
that 0wned is a binary variable any more; there are
degrees of 0wned-ness with a wide range between the
optimist (I replaced` the only program that was
trojaned) to the pessimist (Any compromise of any
sub-component makes the entire edifice untrustable).

part of this is that many of the basic platforms providing internet connectivity
evolved from disconnected/unconnected desk/table top environment ... with
lots of applications assuming that they had full  free access to all resources.

attempting to leverage the same platforms for connectivity to extremely 
hostility
and anarchy of the internet creates diametrically opposing requirements.

one countermeasure from the 60s is to use a dynamically created (padded cell)
virtual machine for internet connectivity ... with limited scope and accesses.
then when the session completes ... the environment is collapsed and everything
is discarded. 

while the native system operation may have little or no defenses against the hostile 
internet ... the padded cell virtual machine environment is used to bound the scope 
of any penetration ... somewhat analogous to air gapping.

I've heard nothing formal, but my strong understanding is a lot of US
government machines, at least if we're talking workstations on
non-classified nets, are in fact 0wn3d at this point. This should
not be entirely surprising as I have heard informally that a
considerable fraction of the machines at Microsoft have been suborned
as well, and if Microsoft can't keep the bots off of their Windows
machines, who can?

What is interesting to me is that, even though things have nearly
gotten as bad as they could possibly get, we still have seen very
little real effort made to improve systems security (at least in
comparison with what is necessary to make a big dent).

I think it's anything but surprising. There's only so much you can do to
significantly improve systems security if you're unwilling to break
backwards compatibility -- many of the fundamental premises of desktop
security are fatally flawed, chief among them the idea that all programs
execute with the full privileges of the executing user.

One Laptop per Child is breaking application backwards compatibility for
a number of reasons, one of which is security. As a result, I'm
earnestly hoping that our systems security platform, Bitfrost[0], will
be an improvement on the scale you're talking about. But time will tell.

(Sidenote: I'm giving a keynote at AusCERT tomorrow about exactly this,
titled 'Everything you know about desktop security is wrong, or: How I
Learned to Stop Worrying and Love the Virtual Machine'. Any list members
who are at the conference should mail me if they want to play with an
OLPC laptop and commiserate about desktop security over beer.)

I don't know what their methodology is, or what their numbers

trust their claims.
