The discussion forum area on Barackobama.com is allegedly the victim of a XSS exploit that redirected comments from Obama's site to....HillaryClinton.com.
A hacker going by the alias of 'Mox' has claimed responsibility for the exploit. Mox argued that the Obama site was not 'hacked'.
It is because what I did was not hacking in the sense that I burrowed into some dusty served and changed the Obama site and stole all your credit card numbers. All I did was exploit some poorly written HTML code."
