Samy, the author of the worm, was on a mission to be famous, and as such the payload was relatively benign. But consider what he might have done with control of over one million Web browsers and the gigabits of bandwidth at their disposal--browsers that were also potentially logged-in to Google, Yahoo, Microsoft Passport, eBay, web banks, stock brokerages, blogs, message boards, or any other web-based applications. Itís critical that we begin to understand the magnitude of the risk associated with XSS malware and the ways that companies can defend themselves and their users. Especially when the malware originates from trusted websites and aggressive authors.
In this white paper we will provide an overview of XSS; define XSS worms; and examine propagation methods, infection rates, and potential impact. Most importantly, we will outline immediate steps enterprises can take to defend their websites.
