On August 3rd, Edward Snowden (or someone using Snowden's Twitter account) tweeted the message "Did you work with me? Have we talked since 2013? Please recontact me securely. It’s time."
On August 5th, Snowden (or someone using Snowdent's Twitter account) tweeted the message "ffdae96f8dd292374a966ec8b57d9cc680ce1d23cb7072c522efe32a1a7e34b0" (which some sources say is a private Bitcoin hash for the amount BTC 0.000911, boosting the theory that the tweet was a "dead man's switch" message and meant Snowden had some kind of emergency going).
Then both tweets were deleted.
Ten days later, a group calling itself the "Shadow Brokers" announced an online auction of hacking tools allegedly copied from The Equation Group, an NSA-associated hacker outfit.
Then Snowden released information tending to confirm the authenticity of the Shadow Brokers offering.
I guess those first two events and those last two events could be entirely unrelated to each other.
But I wouldn't want to bet money on that proposition.
