Careful on this one folks - if you use Internet Explorer, and are not running AT LEAST WinXP SP2, this one can get you, no matter how updated your Internet Explorer is.
The following link is a 'proof of concept' for the exploit.
http://graha.ms/iesploit.htmlIf you go to it, you will see a 'Click Here' link - which when you put your mouse over it, shows
http://www.microsoft.com in the status bar. However, the link ACTUALLY takes you to
http://www.google.com.
Safari (another browser) is also affected, but Firefox is not.
If you use IE, and are not at least WinXP SP2, it is time to start typing in your URLs by hand unless you know and trust the site you are clicking from.
