The 'trick' is to obtain this information regardless of proxy settings and in the case of SOCKS4, be able to identify your real DNS servers. This is accomplished using a custom DNS service along with a Java applet that abuses the DatagramSocket/GetByName APIs to bypass any configured proxy. The source code of the applet is online as well:

Smart TOR users are using Firefox + NoScript + Flashblock to begin with .. and you'd really have to be stupid/trusting to allow Javascript (and even dumber still to allow Java Applets) when you're trying to be anonymous.

As I normally do. Let's also mention that settings in Adblock and entries in the hosts file could mess up the experiment. For those not familiar with the Noscript extension, it can be set to block Flash as well. Flash itself can also be configured for tighter privacy, though if I were serious about anonymity, I wouldn't trust it.

Using a WRT54g+Linux+Tor (or running the TOR router on a seperate machine) prevents this entirely since *all* traffic is routed into TOR and anything that's not falls into the bitbucket.

Here is a person that wants a SLOOOOW connection. ;)

Those that wish to be anonymous .. always will be :)

Let's not forget that those wanting anonymity make mistakes like the rest of us. That's the kind of thing that Moore is trying to capitalize on. Some simply don't like the tracking associated with having a fixed IP, therefore the stakes behind a revealed IP are fairly low. The stakes go up when someone engages in bad behavior, or when his/her Web browsing habits arouse government interest.
