Worm Radar

http://wormradar.com/

I am unsure where this fits but here seems as good a place as any

The developer of the product is a senior antivirus bod at one of the biggest AV companies and this is his pet project

Can I invite anyone to assist with it

download the filke from the site and it's a stand alone .exe that doesn't install but can be set to run on windows boot and run in the background

The aim is to build a network of nodes that detect worms knocking on your door and trace them back

I like it

 

Yes that's true

it won't work if you are behind a NAT firewall on a router but it does work with most software firewalls

It could be a very useful tool in the fight against worms and the website does show where the current attacks or probes are coming from
obviously the more who take part, then better the results and it is very clear that all that happens is that a worm is detected knocking on your door and the program sends a message to the developer with what worm & what port it's attempting to enter
