Wikileaks’ mysterious Vault 7 to be opened tomorrow

In a tweet sent out Monday night, the whistleblowing organization announced the release of the ‘Vault 7’ torrent, with a passphrase to open it to come the following morning.
Twitter user @1080p discovered a hidden image under the original sent out by Wikileaks:
Further investigation revealed the image appears to be of a sculpture created by Jim Sanborn for the Walter E. Washington Convention Center:
And who is Jim Sanborn? According to Wikipedia, he’s ‘best known for his creating the encrypted Kryptos sculpture at CIA headquarters in Langley, Virginia.’ It now seems clear the Vault 7 release will pertain to CIA operations in some capacity, though we’ll all have to wait until tomorrow morning to find out what exactly Wikileaks has been teasing all these months.
