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!
