I noticed something yesterday that was very odd, and I thought I'd share
it with everyone.
I set up a new web site yesterday with a new domain and IP at my web
host. I did this after lunch, because our office network was down, so
it must have been around 1 PM ET that the domain name was set up on my
web host.
I got my first Nimda or some other IIS scan virus at 14:02 PM.
By midnight that night I got 21 failures in the period between 2PM and
midnight, ALL of them IIS vulnerability scans. You can see the logs
yourself at http://www.sujal.net/traffic/fatmixx_07_102.html.
This is amazing to me... I realize the IP address is in a block owned by
a major web host, but still, 21 in my first 8 hours of existence.
I wonder how many infected machines are out there. My main site has
been probed by these things 85+ times since July 1. I've also gotten
what looks like maybe 5 hits for non-Windows-specific attacks (does
anyone remember what exploit NULL.printer is associated with? I'll look
it up later).
