Why would the NSA infiltrate Juniper to change the Dual EC DBRG parameters, when the standard parameters are already exactly how they want them? There is a good chance they noticed that their attacks against Dual_EC_DBRG weren't working - but to reveal that pre-Snowden would prove that they knew the private key and were exploiting it. That said, I understand there was more than one back-door disclosed.
