A spammer with URLs that may be in China staged a big distributed
spam run this weekend using a large network of compromised PCs.
URLs in text: www.rx357.com, www.2004hosting.org, www.2004hosting.net.
Can people at other places resolve those names and connect?  I can't.
China has interfered with connections from Columbia U before.

The spam run was preceded by scans to port 65506/tcp of no known
significance at the time we saw them.  About a dozen students'
Windows boxes that had been scanned were used this weekend in
the spam run.  On Google I see other examples sent from IPs in
many domains.  Sample message below.  All this for a penny-ante
cable descrambler product?  Or is there more to it, if you can
open the web page?
