Re: myspace hack (History of XSS)

That sounds about right.

If I remember correctly, the term "Cross-Site Scripting" (or CSS at  
the time) did originate around 1996-ish. At that time the definition  
was very different. The time when every website was a FRAME'd page  
(remember?). People figured out your could automatically include  
content from other domains on your website using frames. Then using  
JavaScript you could access the content inside those windows and  
cross the website boundary. These issues were reported in the media  
as browser vulnerabilities, most notably Netscape, and the term Cross- 
Site Scripting was born. Maybe we'd be able to dig up the URL's.  
Later the acronym changed to XSS to resolve confusion with Cascading  
Style Sheets.

Today, the Cross-Site Scripting (XSS) definition has expanded to the  
point where the name make little sense. In my opinion, the MySpace  
attack is XSS.
