Hi all -

Great post and great comments. I was glad to see DD's comments because I was thinking precisely the same thing. I recognize that the problem exists, but think it's something that should be addressed by Twitter (or maybe SMS), not every publisher worldwide.

That said, I don't know how Twitter could do anything about it if they want to continue to support updates via SMS. I guess that the idea of "pre-expanding" urls from known shortening services would be a good start. At least then the middleman is removed as a point of failure, etc...

Thanks for clearing that up. #1 in particular makes sense to me. I was thinking of it more from the perspective of a site user rather than a site developer.

I am sure everyone is going to goof on me, but I don't see the significance of the distinction being made between clickjacking and csrf in this exploit. I get that it's not executed in the same manner, but it could have been csrf just as easily, right? Who cares if I am clicking the actual button or an invisible overlay? Tougher for the target site to defend against, perhaps?

Hi guys -

I'm a big fan, but this is my first post. I apologize if it's too spam-y, but I built a twitter knock-off for the iPhone that is picture-centric, rather than text-centric. A couple of posts above sounded like they might be interested in that sort of thing.

Please stop by and let me know what you think. I myself am addicted to it, particularly when traveling and looking for a dead-simple way to share sights with folks back home. Here's the link:

P.S. Please let me know if I have made any security blunders ;)
