Thread:Project:Support desk/Concern my Wikimedia files have been hacked

I have setup a Wiki using 1.16wmf4

PHP is 5.2.4

Mysql is 4.0.4.0

It has been running just about a month, still just configuring it and getting everything right.

I enabled upload and then successfully uploaded a jpg file without problems and the file displayed fine.

A few days later the image was replaced with a link 'filename.jpg' the image was not displayed. Clicking on the link brought up a Malware warning in Firefox and Google, it looks as if the image has been replaced with a link to www.funnyimages.com which both Firefox and Google are reporting as a Malware site.

I'm concerned my MediaWiki files have been hacked.

I tried deleting and reloading the image and loading the image with a different file name, but both created the same results, flagging up www.funnyimages.com as a malware site. The image is not displayed on the Wiki page, just the link.

In order to protect users I have deleted the image files and disabled the file upload facility.

I would appreciate any help in resolving this, not sure if some files have been hacked, or I have not configured the system properly.

Can supply the url if needed.

Any help much appreciated.
