That doesn't make sense as an NSA target, because NSA's adversaries all easily clear that threshold. What NSA supposedly wants are "NOBUS" weaknesses: keyed vulnerabilities for which only they hold the keys.
In the case of the Shadow Brokers, it revealed that those supposed "NOBUS" were low level vulnerabilities that did not need a supercomputer to break.
A vulnerability isn't "NOBUS" just because it exploits an unpublished zero-day. Dual EC was NOBUS because exploiting it required a curve private key that presumably only NSA had.
