If you were in a Five Eyes country and you wanted to contact someone else anonymously, without this person or the government finding out who you are or your location, how would you do it?
The person you are contacting does not know you and you have never spoken before. The only initial contact information you have is an email address, and you wish to send a message, and potentially later some files, in an on-going conversation over several weeks or even months.
Assume neither the content of the message or the files can be connected to you. There is however a possibility that either the government is monitoring this person, or that they are actually working together or have taken over their communication. And finally, if caught you face a good few years in prison for passing on the information.
I am aware that a government adversary of this calibre is extremely difficult to evade if they really want to get you. Would it be enough to:
- Use some form of more secure operating system (Whonix, Qubes, Tails) on a laptop bought in cash, which has never connected to the internet from an IP linked to you.
- Use a different location each time you connect to the internet, e.g. public wifi, or a data SIM and dongle (bought with cash and discarded after each use), and avoiding CCTV.
I assume the first message sent in the above way would be relatively untraceable, but after that?
Or is there a better way? Am I completely off track?
