This is the most recent revision of the document in which DUAL_EC_DRBG
   was presented (specifically, in SP800-90A):
   [1]http://csrc.nist.gov/publications/PubsDrafts.html#SP-800-90-A%20Rev.
   %201,%20B,%20and%20C
   Interestingly, review of this document was reopened for public comment
   a few days ago "in light of recent reports."
   Looks like the version that nytimes links to can be found [2]here.
   It hasn't been confirmed that Dual EC DRBG is used for anything
   important in practice, AFAIK. See

   NYT confirming suspected Dual EC DRBG backdoor, citing leaked memo, but

     But internal memos leaked by a former N.S.A. contractor, Edward
     Snowden, suggest that the N.S.A. generated one of the random number
     generators used in a 2006 N.I.S.T. standard [6]called the Dual EC
     DRBG standard which contains a back door for the N.S.A. In
     publishing the standard, N.I.S.T. acknowledged contributions from
     N.S.A., but not primary authorship.
