It doesn't seem like you're a web security researcher these days unless you find a security hole in Google. So I had 5 minutes spare whilst drinking my brew to find a hole in Google Adsense.

The poc will automatically log you onto your account and browse the Adsense site "as you" before finally posting an update to your address.
In order to protect against this sort of stuff I have posted a couple of demos and articles to help with the process, check them out here:-
