The Dangers of Clickjacking with Facebook. theharmonyguy compiled a list of actions that can be triggered on Facebook by a single click, and hence are vulnerable to clickjacking attacks. The list includes authorising malicious applications, posting links to profiles, sending friend requests and sending messages to other users. Why don’t Facebook include frame busting JavaScript on every page? # 23rd December 2009, 10:20 am

New Facebook clickjacking attack in the wild. I’m not sure why Facebook don’t use frame-busting JavaScript to avoid this kind of thing. The attack is pretty crafty—a Facebook page is positioned with everything obscured bar part of the blue “share this” button, and a fake “Human Test” asks the user to find and click the blue button to continue. # 22nd December 2009, 6:52 pm

Verified by Visa is training people to get phished. Searching for “Verified by Visa” on Twitter produces an endless stream of complaints. I don’t think I’ve ever heard anyone say anything good about it—and it certainly doesn’t make anything more secure. Presumably there’s some kind of legal liability benefit to it, though I imagine it benefits the card issuers rather than the consumer. # 11th November 2009, 10:47 am

Why an OAuth iframe is a Great Idea. Because users should a) learn to be phished and b) not even be given the option to avoid being phished if they know what they’re doing? No, no and thrice no. If you want to improve the experience, use a popup window so the user can still see the site they are signing in to in the background. # 16th July 2009, 8:29 pm

Teaching users to be secure is a shared responsibility

The username/password key’s major disadvantage is that it open all the doors to the house. The OAuth key only opens a couple doors; the scope of the credentials is limited. That’s a benefit, to be sure, but in Twitter’s case, a malicious application that registered for OAuth with both read and write privileges can do most evil things a user might be worried about.
