Re: sober.z to hit tomorrow

Here is some more interesting information. I'm not positive this is Sober.Z related but it's walking like and talking like a duck.

First I see the below DNS requests, shortly after I see many SMTP packets hitting Hotmail, AOL, Yahoo.com, Yahoo.co.uk, Progegy, etc.... Looks like it's... Sending SPAM?!?!
This I didn't expect at all, here is a trace from one of the known infected users:

FYI: I've set some traps on our DNS servers, dunno exactally what this means but I thought that I should share:

Jan 5 18:41:09 myServer named[24490]: client X.X.X.X#1192: query: arcor.de IN MX
Jan 5 18:45:48 myServer named[24490]: client X.X.X.X#1034: query: freenet.de IN MX

These are the only two logs I have at this point. And I don't recall any other Sober searching for an email server.

Wouldn't it be fun if it contained the WMF exploit in some form?
So, I'm planning on using swatch to monitor DNS requests for the known affected domains. What is everyone else planning to do?
