This is a nice recap of where the NSA vs. ShadowBrokers stands at the moment. I do find it mildly intriguing how damaged the NSA finds itself amidst this constant trickle feed of compromised data and formerly secret exploits. One telling line in the article references the NSA (and I am paraphrasing) as one of the premier world wide agencies for breaking into computer systems and yet they could not protect their own house.
I do have to agree with Bruce Schneier and others who point to a whistleblower or other insider theory on the breach. ShadowBrokers wants the NSA to suffer, both functionally and in terms of reputation.
