According to this article from Reuters
Undisclosed until now was that RSA received $10 million in a deal that set the NSA formula as the preferred, or default, method for number generation in the BSafe software, according to two sources familiar with the contract.
However, later in the article they quote RSA as denying this:
RSA and EMC declined to answer questions for this story, but RSA said in a statement: "RSA always acts in the best interest of its customers and under no circumstances does RSA design or enable any back doors in our products. Decisions about the features and functionality of RSA products are our own."
Did the NSA pay 10 million dollars to the RSA to weaken their systems?
Note: I know this is closely linked to Does the NSA build backdoors into encryption algorithms? However, I think this is a different question, because it's a specific algorithm here, and a more specific allegation (and the accepted answer there, which talks about the same algorithm doesn't answer my question).
