They decided the safest way to transfer the sizable cache was to use a USB drive carried by hand to Greenwald’s home in Brazil. As a result, Greenwald’s partner David Miranda was detained at Heathrow, searched, and questioned for nine hours. That’s exactly the sort of ordeal Micah Lee, the staff technologist and resident crypto expert at Greenwald’s investigative news site The Intercept, hopes to render obsolete. On Tuesday he released Onionshare—simple, free software designed to let anyone send files securely and anonymously. After reading about Greenwald’s file transfer problem in Greenwald’s new book, Lee created the program as a way of sharing big data dumps via a direct channel encrypted and protected by the anonymity software Tor, making it far more difficult for eavesdroppers to determine who is sending what to whom.
