Yes, that's right, I'm the proud new owner of microsoft.com. While we're at it, I own yahoo.com and www.cnn.com too.
Internet Explorer users that follow the previous links will be directed to my home page, but will read www.microsoft.com in the address bar. This is because of a flaw in Internet Explorer. Imagine the effect one could achive with the addition of a little DHTML (CSS + DOM, etc.)
Other browsers will direct users to the same page, but will display http://www.microsoft.com%01@home.planet.nl/~acjbizar/index.html in the address bar (which it's supposed to be). By the way, both scenarios only apply when scripting is supported and enabled.
This Internet Explorer Vulnerability was brought to my attention by James.
