You are reading this arcticle becasue you have a joomla based web site and its been defaced or hacked.
Joomla is an open source software and is not secure "out of the box" so you do need to make certain that there are steps taken to prevent malicious users from taking advantage of vulnerabilities in your joomla installation.
Joomla also requires ongoing maintenance in the form of updating to latest version, montoring for plugin updates.
Just installing joomla and celebrating and never touching it again is a mistake.
WHAT DO YOU DO NOW?
The very first thing you should do is go to this link created by Joomla which details what to do whe your joomla install has been hacked: http://docs.joomla.org/Security_Checklist/You_have_been_hacked_or_defaced
NOTE: if you are not technically minded then you should seek the services of a professional joomla developer with experience in securing joomla. You can find such people on odesk.com or fiverr.com.
