Better watch out next time you use WiFi on a plane. Because it's broadcasted unencrypted across the area of an entire continent via a satellite link. And it can be received using of the shelf TV satellite dishes.

Good part is: private connections are mostly encrypted due to stuff like Let's Encrypt.

Bad part: critical infrastructure doesn't use Let's Encrypt.
