International Domain Name (IDN) browser exploit
Schmoo group have released an practical example of a homograph attack. This particularly nasty attack currently works on all non-IE browsers.
Update: As a temporary workaround, I'm disabling IDN in Firefox. To do the same, navigate to about:config and set network.enableIDN to false.
This temporary workaround does not work as a browser restart resets the flag. It is, however, fixed in the latest firefox build.
