Sobig.f surprise attack today

Fri Aug 22 21:04:32 UTC 2003

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.

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