The leakers called themselves The Shadow Brokers, and they sought bTc1,000,000 for access to the remainder of The Equation Group's files. Earlier this month, arrested NSA contractor Harold Thomas Martin was accused of being the source of the leak to The Shadow Brokers, though not necessarily deliberately (he may have been hacked by The Shadow Brokers).
The Shadow Brokers have had no takers for their auction, and so they're now dumping more files, presumably to stir up interest.
The new leak purportedly reveals IP addresses of NSA controlled servers in 49 countries that are used to launch offensives against NSA targets. If the leaks are to be believed, they show that the NSA uses hacked servers in China and Russia to attack other countries.
