Nation-state surveillance threat model for activists using secure video calls

March 18, 2026r/AskNetsec

In r/AskNetsec, an activist describing apparent device compromise asks for a low-cost secure calling setup; replies emphasize threat modeling, compartmentalization, and getting expert help (EFF/Citizen Lab) over generic app advice.

I’m based in Bangladesh and I run a small human rights project documenting abuses by state actors.
I’ve had incidents where private files—stored on my Android device, and files I worked on in Tails (saved on an encrypted USB drive)—were sent back to me by unknown Facebook accounts.
Maybe you can reach out to the EFF or Citizen Lab, etc, to get advice from people who definitely know what they're talking about?
This SCREAMS hardware compromise to me. Try to find hardware that is not connected to you in any way and keep it hidden.
given your threat model prioritize compartmentalization separate devices for calls and research keep systems updated and assume endpoints are vulnerable
