A few days ago, my domain (chattydm,net) was hacked.
This attack injected hidden ads in the header of most of the websites I run/share on this domain, including Critical-hits and the RPG Bloggers Network’s forum. This was most likely done by a hostile script that Corrupted all our php scripts by inserting encrypted data in them.
I’m convinced that this hacking is not infectious, we think its a hostile script that was uploaded to the server hosting our domain.
So while we look for the solution, we may decide to put all our site down until resolved in order to avoid getting blacklisted by Google and give us time to scrub our websites clean.
We’ll let you know.
