      Does anyone have any recommendations for how to conduct a secure over-the-phone interview with an individual who only has access to 2G service (no internet)?

      I’ll have to think. It is easy to do minor things like a simple code, but that won’t work for this use case. What is the threat?

      The threat is a state actor.

      An interview over a mobile phone secured against a state actor. I would say — can you meet them? Or a letter? Cause this is very hard. Crazy ideas are things like a WW2 style cipher, but it wouldn’t work in practice.

      This is a very tough one. Maybe a little more info on the scenario would suggest something but I’m coming up empty. One small mitigation: source uses someone else’s phone.

          If possible, during the call minimise the information leakage, for example “it’s me” rather than “it’s John Doe from Newspaper”…

          Oh yeah, and try to avoid contamination. If you can get the burner number without using them using their existing phone that is much better. (Maybe you can send some digits by “unanswered rings”??) … and use a phone not linked to you or your office to contact their burner.
