This happened just a short while ago, but an important development nonetheless. According to the New York Times:
The initial release, which WikiLeaks said was only the first part of the document collection, included 7,818 web pages with 943 attachments, the group said. The entire archive of C.I.A. material consists of several hundred million lines of computer code, it said.
Among other disclosures that, if confirmed, would rock the technology world, the WikiLeaks release said that the C.I.A. and allied intelligence services had managed to bypass encryption on popular phone and messaging services such as Signal, WhatsApp and Telegram. According to the statement from WikiLeaks, government hackers can penetrate Android phones and collect “audio and message traffic before encryption is applied.”
And here's the link to the vault of documents on WikiLeaks. Haven't had a chance to read through anything yet, but will update as needed over the next week.
Update | March 07, 2017 11:42AM CT
Edward Snowden posted an update on Twitter regarding one of the big call-outs, thus far, from the leak: "first public evidence USG secretly paying to keep US software unsafe."
