   Much discussion about “opsec” (a term I don’t love when talking about people exercising their rights, but whatever) at protests today, including about phones and Faraday containers.

   A Faraday container is probably less useful here than you think it is, but if you do rely on one, make sure it actually works. Here’s a post I did a while back on the ins and outs of containing RF: https://www.mattblaze.org/blog/faraday/

     In particular, a Faraday bag protects you from a very narrow and specific set of phone-related threats, at considerable usability and functionality cost. And they require a nuanced understanding of what they do and what your threat is to use effectively.

     If you don’t know exactly what you need one for, you probably don’t.
