In my own idea

Yes, it is a little confusing about what is free or not, but the fact is companies need to make money else they can't support the software and they use all kinds of ways do to that.  Microsoft patches the culprit will download the patch and counteract it. Wrong, the whole idea of a patch is to fix the problem that allowed the hacker in. Once the PC is patched no more hole for the hacker to use, so you are wrong after a patch a hacker cannot quickly alter his worm, he would have to start searching for another vulnerability to exploit. Computer security companies find viruses and look inside them to find out what they do. Sometimes these worms are programmed to attack on a certain date. So they do announce the date that the attack will take place. 
Federal Agencies monitor general internet infrastructure to make sure it's not under attack, but I'm pretty sure it would be public knowledge not some underground hidden agency.Who ever is responsible for this so called "worm" is going to announce the date that it will take place.
