I'd love to see some insight as to how they were able to generate that domain name. Surely if they can do that (years ago, even), then a well-funded adversary would be able to generate the same now, given enough time.
Maybe it took x thousands of compute years to generate the secret key for `facebokcorewww` - and they didn't care about the last character. But still, let's say you're a government agency with endless resources - how hard would it be to recreate that private key? If a private corp can do it once with finite resources - why can't you?
Was it is just a stroke of luck for those working on it? What are the chances?
