How Reporters Pulled Off the Panama Papers, the Biggest Leak in Whistleblower History

Obermayer tells WIRED he communicated with his source over a series of encrypted channels that they frequently changed, each time deleting all history from their prior exchange. He alludes to crypto apps like Signal and Threema, as well as PGP-encrypted email but declines to say specifically which methods they used. Each time the reporter and source re-established a connection, they would use a known question and answer to reauthenticate each other. “I’d say ‘is it sunny?’ You’d say ‘the moon is raining’ or whatever nonsense, and then both of us can verify it’s still the other person on the device,” Obermayer says.

“The ICIJ’s developers then built a two-factor-authentication-protected search engine for the leaked documents, the URL for which they shared via encrypted email with scores of news outlets including the BBC, The Guardian, Fusion, and dozens of foreign-language media outlets. The site even featured a real-time chat system, so that reporters could exchange tips and find translation for documents in languages they couldn’t read. “
