The Avtobaza systems the Russians supplied can supposedly do this.
Jam? Yes. I think that's at least possible.
Hack? I doubt it. I would suspect that the encryption the drone uses is rather strong, and there's probably some sort of electronic version of a one-time pad that is synched before launch that makes it unbreakable.
The whole thing is rather suspicious. The drone looks surprisingly intact. The whole "find a suitable place to land" programming makes some sense, but in an enemy country? I'd think that while it might have a database of suitable flat places to put down in an emergency, I doubt it has vision systems, radar, etc. that can actually pick out a completely tree, rock, or debris-free path to land on.
And why is Iran hiding the undercarriage from view?
- Because we did lose a drone, but it's smashed, and this is a mockup for propaganda purposes, and they don't have reliable intel on what the undercarriage looks like, and don't want it called out as a fake. And maybe Obama was just calling their bluff by asking for it back?
- If it is real, it's covered because something about the undercarriage would give away how they got the drone down?
Like Fitz, I too wonder if this is some sort of ploy to get Iran/Russia/China infected with 'Stuxnet 2.0'.
There's major stuff here in the story that just... does... not... add... up... Both on Iran's and Uncle Sugar's side of things. And it's just a gut feeling, but when things "get complicated" I'll give the advantage to the more advanced and technically savvy nation.
Hell, if I were No-Such-Agency, I'd be ordering fake drones, and dropping/crashing them all over enemy countries. I'd fill them with all sorts of gonzo head-scratcher stuff, like a tube of magnets and wires where the jet turbine should be, tanks of liquid carbon dioxide, and fill it with fiber optics, and instead of microchips, have junk circuit boards with little crystals mounted in them that I'd gathered up from the Smithsonian gift shop's "box o rocks". Add in a mix of fake squiggly alien writing on some of the parts too with a mix of bogus U.S. NSN's.
