Google Hosting - Not So Secure?

It seems that Google's hosting service "Google Pages" has been targetted by "malicious users" (I've always loved that expression) who have been able to upload some form of Trojan. The online giant has been getting quite a bit of flak in security circles of late due to some of its quite dubious decisions regarding email headers and redirectors. It probably won't have any real impact in the long run, but as it is Google it will always attract a certain level of media attention.
