It was reported yesterday in The Guardian and elsewhere that the NSA paid RSA $10M to set Dual_EC_DRBG as their default PRNG. See the news here: http://www.theguardian.com/world/2013/dec/20/nsa-internet-security-rsa-secret-10m-encryption.
As we have previously stated, we never implemented Dual_EC_DRBG in any of our products, much less set it as default, because of its suspect nature. If you`re not familiar with Dual_EC_DRBG, the background on wikipedia is here: http://en.wikipedia.org/wiki/Dual_EC_DRBG.
For even more background, here`s a great Black Hat talk by Derek Soeder, Christopher Abad, and Gabriel Acevedo from Cylance on the subject of breaking Pseudorandom Algorithms.
