The “Hands on Series” continues!
In this episode we start dealing with Cross Site Scripting (XSS) attacks.
CSS = Cascading Style Sheets
XSS = Cross Site Scripting
Cross Site Scripting is a technique used to add script to a trusted site that will be executed on other users browsers.
A key element to XSS is that one user can submit data to a website that will later be displayed for other users.
It is nessesary that the bad guy NOT mess up the HTML structure, otherwise the result will be web defacement rather then attacking other users.
The hackme site has been updated and improved (more about that in a moment)
and now includes a section for XSS which we will be using in this episode.
