Re: Publishing Nimda Logs

Why not publish the list and only include the source netblock. That way 
your still getting the info out there, but your not allowing a script 
kiddie to simply cut and paste your host list into a bot script.

1 and 3.  Some people (those not running MS Crap) probably won't care, but
if it's something you want to do, why should that stop you.  On some of my
personal systems, I've actually setup code to watch apache for Nimda/CR
sorts of requests, and firewall them for 24h in addition to emailing me
the IP, mostly to keep them from filling my access_logs with their crap.
I've also implemented this on a big web hosting server because Nimda/CR
probes were actually causing performance issues on the server.

This has doubled as an early warning system notifying me that a Windows
running coworker has been infected before they know it.

If you maintain a list that's easily fetchable, it wouldn't surprise me at
all if some people choose to grab it at regular intervals and use it to
block access to their web servers.
