I did some googling, seems like Joomla! has a severe security issue a few weeks back, where even its own site, http://www.joomla.org was hacked.

Just a word of advice, update your Joomla! NOW!

allow an unauthenticated, unauthorized user to reset the password of the first enabled user (lowest id). Typically, this is an administrator user.
