Yokoso!

The first I saw of this was on one of the Twitter posts from someone I follow. This is a sourceforge project.

On a read of the sourceforge page you'll see:
Yokoso is a project geared toward fingerprinting infrastructure. Yokoso will determine what web interfaces are available on a specific network.

But based on the net-security article it is a bit more. First it tries to exploit your browser, goes through and finds out what sites you may have admin rights on, and then does some type of fingerprinting.

I'm going to try to find some time in the next week or two to test this out, if/when I do I'll post back my results. It looks promising, but anything doing browser exploits makes me nervous.
