That wasn't reaaaaly an AWS hack. BGP hacks are still an issue since it is mostly an honor system! There are no safeguards against this except fast admin.
Well, there was that too. What I was referring to was a specific issue that allowed you to add entries for domains in r53 which were already in use (in r53). I can't remember the specifics too well, but I think it was an api validation issue on one of the endpoints. It wasn't a "I own your domain now" so much as "I receive some of your traffic sometimes".
