This is a terrible own goal. The RSA show is the main trade show for the industry. Right now we need as many people to be finding out about security products and controls they can deploy to defeat the NSA as possible.
RSA got punked by a social engineering attack. It happens. I can't see any reason why the NSA would tell them the real reason why they were pushing the Elliptic Curve random number generator. But there was no secret about the NSA pushing for Elliptic Curve.
The RSA deal wasn't secret either. Certicom got $15million for the licenses. The story out was they wanted everyone to start being serious about Elliptic Curve. I worked for a competitor at the time and I knew about the deal from industry gossip.
Of course now with the hindsight of the document dumps we know that the NSA was stabbing us all in the back. But we have to focus on the real problem here not turning on each other.
I have a friend who was in the civil rights movement. When I told him about the NSA activities he told me that the worst damage done by the FBI attacks on them was to create the suspicion that everyone might be an informer.
