Is anyone aware of any network-based signatures that could be used to
identify and tag IP traffic, for dropping at the ingress/egress points?

I am uncertain also. I scan a subnet on my network with Axence
NetTools looking for 445 port and I receive some hits. I perform a
netstat -a some of those results but don't really see any 445
activity.  The SCS script doesn't find anything either.  The PCs are
patched and virusscan updated. One PC when I connected to it did not
navigate to Windowsupdate website. I scheduled a Full McAfee scan as
their documentation suggests
(

),
and sometime through the scan I was able to reach windowsupdate. I
don't know if it was a coincidence or not that I was not able to reach
the website.  I haven't looked into the registry and any other places
for evidence of conficker. I will probably today but I am afraid it
maybe a waste of time since they are already patched and updated.

Here's the link for the Python Crypto toolkit:

I scanned our internal network and didn't find anything, so I can't
really
vouch for it's reliablity though.
