The Shadow Brokers dump has shown us many things, things that bear not repeating.
But interesting clues came about from the leak which appear to show how the NSA broke in are in this motherboard article.
In a leaked text file inside a folder related to the apparent NSA hack of the SWIFT service, there's a URL and a string that says "QUANTUM against EASTNETS employee network in Duabi [sic]." The file is titled FATags.txt, with FA likely standing for FoxAcid, an NSA tool. This was presumably an instruction for the operator to know when and how to use QUANTUM.
