Share external link automatically?

I have stumbled upon something pretty interested lately. I was browsing a website and when I got back my FB profile I recognized that I have shared the browsed site on my profile without my permission.

This must be something like a clickjacking script like if you click ANYWHERE on site XY, you automatically share site XY on your wall?!

Anyone knows how this works? Just a general clickjacking script or something more complex?

Cheers

That is a basic mousefollow javascript code, it is shared here if you search.

Now the hard part is making it work, facebook has implemented patches to try and stop this type of thing from happening. There are a few successful methods that work to bypass this patch, but I doubt anyone will share them with you here.

if you put the link i can tell you if is simple clickjacking or some xss on fb
