In a new article in Harper's Magazine, the duo finally tells their story of beginners' encryption, convoluted codewords, and extreme paranoia. They also reveal that they are not the only people to have received Snowden files without the public knowing about it.

Dale Maharidge is an award-winning journalist and professor of journalism, but was only pulled into the Snowden leak because of a Brooklyn house party he attended one night in December 2011, where he met filmmaker (and Intercept co-founder) Laura Poitras. The two bonded quickly over their work and, throughout the following year, as their respective reporting and film projects allowed, spent time together in New York and at Maharidge's "very remote" coastal dwelling in Northern California. Then, near the beginning of 2013, Poitras was contacted by an anonymous source claiming to possess materials that would reveal the scope of American surveillance. She confided in Maharidge: 

We talked about the source over dinner, and Laura told me that this person wanted a physical address to use in case (as the source put it) "something happens to you or me." We speculated that perhaps this person might want to send her a parcel. Hard copy? Data? It was unclear. Needless to say, the material couldn't go directly to Laura: her mail was surely being scrutinized. Nor could I receive it, because of our connection. She said we needed a third party, someone who wouldn't be on the NSA's radar.
