A couple articles regarding a Joomla site for Harvard's Graduate School of Arts and Science being hacked. The twist in this is that the database was made available via BitTorrent. Luckily, for Joomla! users, early reports indicate the hack was due to weak password usage and not an actual exploit in the Joomla! software.
