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. :)

Was the purpose to denial of service attack them? If so we just assisted that.. :) mark -- Mark Segal Director, Network Planning FCI Broadband Tel: 905-284-4070 Fax: 416-987-4701 http://www.fcibroadband.com Futureway Communications Inc. is now FCI Broadband -----Original Message----- From: netadm [mailto:netadm () infolink com] Sent: August 22, 2003 3:50 PM To: nanog () merit edu Subject: RE: Sobig.f surprise attack today From http://www.f-secure.com/v-descs/sobig_f.shtml ----------------------------------------------------------------- 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. -----Original Message----- From: Andrew Kerr [mailto:andrew_kerr () iamnos ca] Sent: Friday, August 22, 2003 3:43 PM To: Jay Hennigan Cc: nanog () merit edu Subject: Re: Sobig.f surprise attack today Jay Hennigan wrote:On Fri, 22 Aug 2003, Andrew Kerr wrote:Its been posted here, and f-secure has it, but I wrote aquick scriptto keep an eye on the 20 servers and dump the output to asimple page:http://207.195.54.37/sobig.html (Updates about every 5 mins)You're probing the list of NTP servers the worm uses to getthe date,not the list of hosts to which it "phones home".A few people pointed that out.
