I don't think the purpose was to DoS them.  It looks like some of them were
hosts on Comcast's cable network, probably some user machines being used to
host the second part of the payload.

I just want to know what the second part of this thing does.  It's better
than watching TV.  :)

My questions is what were those servers.. Was the purpose to denial of
service attack them?  If so we just assisted that.. :)

Update on 19:00 UTC 

When deadline for the attack was passed, one machine was still
(somewhat) up. However, immediatly after the deadline, this 
machine (located
in the USA) was totally swamped under network traffic. 

We've tried connecting to it, just like the virus does. We do 
this from
three different sensors from three different machines in 
three different
countries. We haven't been able to connect to it once. If we 
can't connect,
neither can the viruses. 

So the attack failed. Whoa. 

We'll keep monitoring until 22:00 UTC. If we're not able to 
connect once, we
can safely say that the attack was prevented.

You're probing the list of NTP servers the worm uses to get 
the date,
not the list of hosts to which it "phones home".



A few people pointed that out.  By the time this message hits 
the list, 
it should be corrected.
