Morning All,
It appears more likely that ECC standards were backdoored by the NSA, 
with NIST involvement (or lack thereof?).
I hate to re-post slashdot, but the summary is concise:
http://it.slashdot.org/story/13/09/11/1224252/are-the-nist-standard-elliptic-curves-back-doored
The trick, it seems, is in some random seed numbers which aren't random 
at all:
"The random numbers in these curve parameters were supposed to be 
selected via a "verifiably random" process...
Unfortunately it turns out the actual inputs used were opaque 256 bit 
numbers, chosen ad-hoc with no justifications provided."
Good times.
