Do we know if anyone has looked at the code for variants of the

spread itself until the 19th and then switch to attacking the IP

with different dates and different IP address or attack scenarios?
I tried sending info to the list but may not have posting
priveleges. Anyway, you can relay this.
I have a home system on Sprint Broadband, with a little sniffer on
port 80 to see the full payload of what is coming in. Starting this
morning a new variant of CodeRed started hitting, with a lot more
frequency than I ever saw from the original.
This variant has the text "CodeRedII" in the payload. It also has
the names of the windows registry entries you would want to hit to
install a rebootable trojan. It does not have any domain name in it,
and nothing about "Hacked by Chinese." It has XXXXXXXXXXXXXXXXXXX in
the payload instead of NNNNNNNNNNNNNNn
The class A domain with by far the greatest number of hits belongs to Sprint.
I dumped some statistics on which class A prefixes had at least
three hits. I also dumped the total number of CodeRedII hits by hour.
I don't have time to disassemble it - I am just watching out of
curiousity, so I don't know what else it is doing.
here are my hourly stats so far. Time is GMT.
Here is the domain breakdown:

Feel free to mention this to the list if you want, since my mail is
not getting through.
