Through the following post I am not purposing to influence you to start defacing, but to briefly give you a better understanding of how and why it is done.

Almost everyday I visit Zone-H’s archive of special digital attacks, I find that at least 1 or 2 attacks were done against US governmental web servers. The domain suffix of the defaced websites was *.gov. Does this fact means that they are totally secure? I don’t think so… Obviously the web servers may host very confidential data. In this case the web server administrators seemed to have allowed threats against governmental assets. Any unwanted consequences that a breach of security can lead to, are mainly caused by the irresponsibility and lazyness of system administrators and web developers.

My friend SuRGeoN from Greece wrote a very interesting pen-test paper which explains how easy is to convert an internal network into an external with the port redirection technique. He demonstrates the attack scenarios – including network architecture diagrams – and goes into great technical details about them.

The goals of XSSed.com are to provide informative resources on cross-site scripting(XSS) vulnerabilities and exploitation methodologies, and to archive XSS vulnerable websites for statistic purposes. Mirroring websites is a way to prove to vendors and webmasters that the vulnerability really existed – in case of denial. Users will become more aware on protecting themselves on some websites, as XSS vulnerabilities are mostly targeting the users and not the websites.

XSSed.com is also an attempt to spread education and awareness about XSS to IT professionals and amateurs involved or interested in secure web application development.
