Pretty crazy to think that it's sitting like this in the open, with its old APIs all ready to be pentested. Secured by literal obscurity, introduced by a distance of a light day from the closest hacker.
But it's still super easy to find them.
Usually it takes a few hours until the sat ham guys find them and post spectrums.
But today, Voyager 1 is a 50 year old curiosity, still of interest to cosmologists of course, but governments will be less interested in it than archeologists.
