follow the link

http://www.microsoft.com%01:www.linux.org%01@www.freebsd.org/

The IE will redirect you to www.freebsd.org <http://www.freebsd.org/> .

Its mean to be a fall at IE authentication method, used for automatically to
connect to sites that require authentication.

umm tested this you dont need %01 either btw.

 

www.microsoft.com@www.linux.org

 

was messing around with some hex stile as well is there a way to call a
file:// inside a http:// becos the issue with doing the @ trick is it
appends http:// automaticly, mind you , u could just make it exec some vb
code or something on a site, just a random idea any way

 

and it dont also seem to work if you use hex as well for the full domain ie

 

www.microsoft.com%40%77%77%77%2E%6C%69%6E%75%78%2E%6F%72%67

 

nor  www.microsoft.com%40www.linux.org

 

where as if you www.microsoft.com@%77%77%77%2E%6C%69%6E%75%78%2E%6F%72%67
works

Hmm, it doesn't seem to work on my browser :) 
I don't even get transported to any page when i click the button. 
But then again, i have everything turned off in the internet zone by
default... 
(but my submit non-encrypted form data is on) 

Does it really work then?  it looks like it's using javascript...?

Merry Christmas everyone :)

LOL. This is so simple and dangerous, it almost made 
me laugh and cry at the same time. Most of you will 
realise why...;D 
The Paypal, AOL, Visa, Mastercard, et al email 
scammers will have a harvest of gold this month with 
lots of zombies falling for this simple technique.

Dont be surprised if your latest download from
