evalda For security I would use SimpleXChat, not signal. I'm trying to use snapchat to give my SimpleXChat link. Authorities couldn't read my chat on SimpleXChat, but if they investigate me from snapchat, they have a chance to trap me if my coworker don't got a good opsec and leaked our messages, is 2 phone really usefull?
I'll detail my whole opsec.
First, there is two things. I don't want to get my messages reads, and investigations on me. If my messages got reads and there is an investigation on me, I want to keep my anonymity over years.
I will split the opsec between two part, my opsec, and my coworker opsec.
- My opsec : I will use a phone bought in second-hand with cash. I will add GrapheneOS. On that phone I will use everyday Snapchat ( Bad ) and SimpleXChat ( Good ). While using the phone I will use a public wifi and always use it for maximum 10-15 minutes. I will use a faraday bag, and take the phone out of the bag only while using it. Physically hide/destruct the cameras/microphone. I will use the maximum settings on SimpleXChat and ALWAYS use orbot, I will also use orbot for creating the ProtonMail, the snapchat account, downloading any app, etc.. I will also encrypt the whole OS ( idk if that's possible on GrapheneOS ) with a strong password, and try to create a isolated environment for snapchat, who is a spy literally. I heard that I could do that on GrapheneOS
My coworker opsec : He will use his real phone, with his real wifi. He will always use stenography ( I will meet him and give codes that only him would have ). He will use SimpleXChat max settings and also Orbot. He will probably get fucked pretty fast, but if I don't get caught, it's good for me.
