Don't Panic!
Before the FUD starts flying in this forum too, lets keep a few facts on the table.
1) this is only a video feed from an onboard camera, not telemetry video with the overlays that someone at the drone's remote console sees.
2) the drone is not hacked. This is a man-in-the middle reception only process. In no way are they ineracting with the drone.
3) the control frequencies are not interfered with. Those are highly secure, and come from multiple redundant points. Even if they could interfere with those bands and jam the drone's reception, it has a flight and return plan based on waypoints and GPS guidance, it can't be remotely crashed.
4) hacking a drone, even if you could decrypt the signal, not only would rely on getting it to respond, but you'd have to know intimate details of the control signals. You can't just plug a joystick into a laptop and expect it to turn left when you do.
5) if its anything like other flight computers I've seen, and worked on code for, it's not one computer, but 3, running on different hardware platforms and running on different OS. ALL THREE have to generate the same response at the same time in order for it to accept input. If one system goes rogue because it's been hacked, the other two ignore it, and the operator is informed a computer is down.
6) being close enough to get this feed, if it's coming for you, is simply notification you have a few minutes to live. When the drone(s) do arrive, as they did on a village early yesterday, they come in packs, and drop 10 or more missles in numberous runs. If you got the feed, and fled, the pilots watching the feed could simply take out your truck too.
7) even if you knew one was coming, and were ready with a shoulder launchable surface to air missle, odds of you hitting this drone are real small, and you're dead anyway. They're expendible, likely you don't think you are yourself. It's why we designed them...
8) the "predator" HAS been redesigned. The feeds are from older birds we still use, but there's already a 3rd generation shipping to the military, and a 4th generation in the works, as well as hardware overhauls on older units, no differnt than the F16 has had numerous computer replacements over decades.
Honestly, this is not a big deal. The video is crucial for manual operation that it be smooth and digital error free. Back in the 90s, encrypting in real time a video feed like that in such a way that dirty frequncy bands would still produce clean video (lots and lots of ECC on top of the encryption), would have added rediculous computational requirements to both the bird and the pilot station equipment, and would likely have led to video feed processing delays of a second or two, we simply did not have the tech to do it.
