Just a quick tip for you guys that have Windows machines to worry about
on your network that might be infected with this new worm. The
one-liner:
"nmap -v -p 3127-3198 192.168.0-128.* -oG nmap.txt > /dev/null && cat
nmap.txt | grep open"

will scan for and identify the IP's of any infected machines for you, if
you replace your network information for the dummy information in the
example above. I've been running this on my network every couple of
hours. So far only one infected host! yay! Oh, and it will also hit on
any squid boxes you have running as well since squid defaults to
listening on port 3128. Since we are only scanning a few ports it's fast
too, takes about 90 seconds to scan all my networks, which consist of 6
class C subnets. Hope someone finds this useful!
