AFAIK, the main novelty is the ease with which bogus NS records can be inserted. It may be hard to get a specific A record (www.victimsbank.com) cached, but if you can shim in the NS records of your ns.poisoner.com authority, then getting the real target A record is trivial since you'll be asked directly for it (and can wait for the legit clients to ask for it for you).
