I can confirm that this is indeed a legitimate issue and there is real
traffic happening. I can't give specifics but where I work we've blacklisted
2 entire subnets due to this issue, a /19 and /20 respectively. The majority
of the sites hosted within the subnets are porn but there are also
legitimate sites that appear to have been compromised with tagged payloads
that are not related to the ad network Larry mentions.

The numbers come mostly from porn sites that use a low brow
ad network that is inserting the graphics into the sites. If
you really want to see one, go to 600pics[dot]com, but be
forewarned of hardcore porn.
I haven't seen any reports of innocent sites being affected by this.

Just curious. I hear media reports and people saying that
there's hundreds or thousands of compromised web site from
this, but I have ask where these numbers come from? Where is
this data, or is it pure speculation? I'm also curious how
one could compromise a web server with this exploit. Putting
files on a web server to dole out and compromise other
computers I can see, but is the web server really compromised
in this case? If so, was it by way of the WMF exploit?
One last question: Has anyone here experienced or know
anyone that has a "legitimate" web server compromised (or
serving out) by the WMF exploit.
I'm trying to determine if there are those with actual
knowledge that the sky is indeed falling, or if we are all
shaking over unsubstantiated media hype.

Overall, I think community's coverage of wmf has been
delivered with
an ounce of perception, and a pound of obscurity. It's
almost as if
people *want* it to be worse than it is. I'm not surprised, of
course. But regardless, my call is that we'll see a little
activity here and there, the patch will come out, most
will install
it (or have it installed automatically) and the whole issue will
fade away. But that's all.
We'll know for sure shortly, either way.
Thor,
I think your path of thought is stuck a bit in the past.
Worms are neat as a technical exercise, but we see more and
more that
the attackers are increasingly aware of the value of these
vulnerabilities from a financial perspective, not merely for
notoriety. As such, it benefits the attacker to have a less subtle
attack, one that does not sensationalize the vulnerability.
Complacency is their ally.
That said, there are already numerous (hundreds+) "legitimate" web
sites that have been compromised and had exploit images
injected into
their content. There are also already hundreds of thousands of
machines that have been infected with Trojans or bots.
These infected
machines will patch, but they won't be safe, and the problem gets
worse.
So no, there won't be some catastrophic worm event. But I
posit that
what there will be could be much worse.
