> This list of 8273 hosts hit CIRA's DNS servers exactly 12 times with
> the same MX query on more than 5 occasions and appears to fit the
> topic being discussed on dns-ops related to the large botnet hitting
> 'spambot killer' webpages.
> Also likely related to the .CL and .BE attacks, etc, and is being run
> by the alias 'Aleksej Iliin' as part of the RBN.
> I also have a 2.3Meg file containing the domains queried, in case
> anybody out there wants to compare strings there, hit me up off-list.
