ANSI standard group members and Microsoft employees Dan Shumow and Niels Ferguson made a public presentation about the backdoor in 2007. Commenting on Shumow and Ferguson's presentation, prominent security researcher and cryptographer Bruce Schneier called the possible NSA backdoor "rather obvious", and wondered why NSA bothered pushing to have Dual_EC_DRBG included, when the general poor quality and possible backdoor would ensure that nobody would ever use it. There does not seem to have been a general awareness that RSA Security had made it the default in some of its products in 2004, until the Snowden leak.
