Hello guys, Recently I've faced this probleme on one of my sites built with Joomla, so i want to share this with the community as it's related to SEO. Somebody injected me this code to all my PHP pages: it's coded with base64! All my keyword that was ranking on the top 5 gonne to the 5th page!!! And when somebody type a keyword related to my niche and click on the result on google he's automaticaly redirected to this page: I really don't know how they've done to inject this to my site... Anyone here knows how can I do to avoid this by the future? And how can we do this? It's a great silent weapon, you can't know that ur site is infected ur site drope in the serp and u can't know it until u click on the result on google to see the catastrophe!!! PS: Sorry for my bad english.
