I've recently found out that my web page in Moodle is rendering hidden spam links in every page it delivers. There have appeared some new code folders and they are somehow intercepting the contents and adding links.
The html code they add is something like this, just behing <body> tag:
<font style="position: absolute;overflow: hidden;height: 0;width: 0">xeex10501 <a href=http://some_website.com/>Nightwatchers Insomnia</a> <a href=http://some_website.com/>shaman king view full episodes</a> <a href=http://some_website..com/>fat soluble vitamins in fishes pdf</a> <a href=http://some_website.com/>norton antivirus intelligent updater</a>
This is obviusly made by a bot taking advantage of some vulneraibility, but I'm not sure if this is caused by a Moodle issue or a bad server/ftp configuration. Making a bit of research, I discovered that this is only happening in Moodle websites. You can see it through a google search: www.google.com/search?q="xeex10501+Nightwatchers+Insomnia"
Anyone has faced this, or know how to solve?
