RE: Sobig.f surprise attack today

  • From: netadm
  • Date: Fri Aug 22 15:53:30 2003

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.
