I think what we would need to know, in order to determine the strength of this evidence, is how many total IPs North Korea is known to have used in previous attacks, and how many total were used in this one. I.e., how closely correlated is prior NK use with an IPs use in this case. If only a handful were used on both occasions, and the overlap is significant, then we have some fairly interesting evidence. But if, on one of more occasions NK used hundreds of IPs, and there are a handful in common between those two sets, then there's really nothing to see. I've had the impression it was the former, but perhaps I'm mistaken. Does anyone have an answer?
