If you're just starting to follow TheShadowBrokers story now, I'd recommend catching up by reading up on TheShadowBrokers (google it and pick your favorite news outlet, I guess). For this specific story, you should read up on monero as well at getmonero.org.

This post is the 3rd I've written about TheShadowBrokers and basically just a continuation of the earlier 2 posts.

Honestly, there's so much background information that someone could write a book on it.
