The legwork in the paper is interesting and worthwhile; they tracked down actual implementations and worked out the whole attack. But if you're going to go around gunning for something, it should be software AES, not CTR-DRBG.

I'm worried that people won't take that away, because "DRBG" is a weird NIST term that people might read too much into. But "DRBG" pretty much just means "CSPRNG". There's no relationship at all between Dual-EC and CTR.
