Not really. While both relate to SHA-1, those are two quite different issues. The Shattered attack was an actual demonstration of a long-known weakness in SHA-1 that allows creating practical collisions. This one is more an exploration of the question whether a malicious actor can create a standard that looks good, but is actually weak. Those questions got quite a bit of attention in that time due to the Snowden leaks, and the realization that this actually happened at least in one case (Dual EC DRBG, which, technically, was already known before Snowden, but only got major attention afterwards).
