I recently took a trip to Moscow to interview National Security Agency whistblower Edward Snowden about operational security. In the article I published on The Intercept, I mentioned that I used a faraday bag.
Our first meeting would be in the hotel lobby, and I arrived with all my important electronic gear in tow. I had powered down my smartphone and placed it in a “faraday bag” designed to block all radio emissions.
Since I published my interview, many people have asked me for more information about this faraday bag — which product did I get, what does it protect against, how does it work? So here are some quick thoughts on the topic.
