#13They used XSS (cross site scripting) to send a mail to the target. When the email is viewed a CSRF (cross site request forgery) is executed to add a new device (phone) to the authenticated devices list. Next they log in, receive the SMS on their phone that is now in the list...bam!
[Edit: I didn't mean XSS to send the email, I meant inject an XSS attack into the email and send it. I'm thinking something like psuedo: location.replace(/link/to/add/device/?phone=555-1212 ]

They probably sent the mail like you said, only used the CSRF to jack the cookie, which would be easier than adding a phone to the list.

#17I wonder if they have a viable business after this. Seems like this could be a deathblow right off the bat.
