Would anyone be able to hack Voyager? Just wondering - if the software is that old, as long as you can get a signal to it anyone should be able to hack it / wipe it right?

Is the biggest barrier the enormous satellite dish you'd need to contact it or do the commands have a auth header with some key you'd need to brute force?

I think the big radio telescope is the main barrier. At this point there's only one in the world with enough transmit power to talk to it, and a handful that can receive the signal.
