It's Just a Tool

Let's hope Oath Keepers are the ones using it. [More]

And no, I don't say that as an endorsement of "Only One-ism".

All these UAV's seem to me to have one flaw - radio control. Seems like a decent tech should be able to either jam the control signal, or better yet use a higher powered transmitter and steal the thing. Surely the control link is encrypted, but meh if a 17yo hacker can break the crypto for free porn, someone out there can crack this baby.

I'm thinking the threeper community needs to come up with a man portable, small area EMP generator which isn't a threat to personnel.

well everything wireless is subject to jamming; you don't need to care about encryption when you can just dump noise into the right channel. the downside is that you then have an extremely loud presence, telling everyone nearby exactly where you are.

AUVs and UAVs usually have mission systems that are uploaded ahead of deployment, and can be used in place of manual control, or if manual control is lost. these generally include failsafe systems when they are not cabled for testing; typically, AUVs will drop their anchor, surface, and ping their location until the battery dies.

beating encryption in real-time is not trivial with the thing flying past you at speed. in 802.11 stuff, for example, you need time to get enough frame samples before you can crack a key. but, you'll need to know ahead of time or be able to figure out what you are dealing with at each layer: physical, access, link logic, and so on, before you can even find the start/end of said frames.

but, yeah, it can all be done. gonna cost ya.

Very high level target practice... expensive, but what the hell. WE paid for it.

I think axing this and not a missile defense shield the day after N. Korea does a test would have been a better idea.

Reminds me of Terminator. Life imitating Art?
