US Sentinel Drone Fooled Into Landing With GPS Spoofing
McGruber writes "Following up on the earlier Slashdot story, the Christian Science Monitor now reports that GPS spoofing was used to get the RQ-170 Sentinel Drone to land in Iran. According to an Iranian engineer quoted in the article, 'By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.' Apparently, once it loses its brain, the bird relies on GPS signals to get home. By spoofing GPS, Iranian engineers were able to get the drone to 'land on its own where we wanted it to, without having to crack the remote-control signals and communications.'"
The more important aspect of the truth that's slowly leaking out is that U.S. officials are finally admitting that it was on a spy mission inside Iran and dropping that ridiculous cover story that it was just flying around Afghanistan and accidentally may have strayed into Iran (oopsy, whoopsy, did we cross your border?!?).
Of course, most non-idiots have known for some time that the CIA and Mossad have been in a state of undeclared war with Iran for several years now--assassinating their best nuke scientists and engineers, spying on their facilities, helping fund the Green movement, releasing Stuxnet and other viruses aimed at sabotaging them. etc., etc. But die-hard apologists (who seem to think that all those people at the CIA just stare at the wall all day, I suppose) have refused to accept this. These are probably the same people who believe the Pakistani government when they claim they had no idea Osama Bin Laden was in that compound in Abbottabad and that they're still our good friends (please keep sending us your money, infidel allies). But I digress.

I just know somewhere in the process of the multi-billion dollar drone development project someone must have said, "You know. I think a self-destruct mechanism might be a good thing to add." Of course, I can also imagine someone saying, "Yeah, they'll never even see it. It's stealth."
putting aside allegiances for a moment and looking at this from a purely engineering standpoint: bad ASS!!

So, first of all, this is just really neat. It sounds like something that would happen in a movie. That's some movie-hacker shit right there.
That aside, the thing that really worries me here is that the military's GPS was able to be spoofed in the first place. One would think that the GPS the military relies on would be encrypted or something, y'know? How difficult is it to spoof military GPS?
was an expensive military drone using civilian GPS? The military has encrypted GPS signals (the P codes), which I very much doubt have been cracked. I'll bet someone made a decision to fallback to relying on unencrypted signals, instead of self-destructing after X minutes, upon loss of the encrypted signals.

Also, there was the 2nd drone crash that happened recently after the Iran one, here. They didn't cover this one as voluminously it seems. And now we see this.
Bad month for US drone interest and parties involved.

(land in Iraq, really?) Anyway, jamming isn't terribly difficult, especially when you're that close to the receiver. But "spoofing" GPS signals is a great deal more challenging. It's not the data on the gps signal, it's the timing that is the position information. If they were able to pull THAT off, they deserve the drone. and a pat on the back.
If I had to guess I'd say they were lying about doing that, possibly hoping to make the US start questioning their reliance on GPS, since it's proving such a handy arms tool.

Those GPS spoofers got to Slashdot too, apparantly, fooling the editors into thinking that the drone landed in Iraq.

"We all feel drunk [with happiness] now," says the Iranian engineer. "Have you ever had a new laptop? Imagine that excitement multiplied many-fold."
You don't have to crack the encryption. You can just record and playback the signals from the satellites, with appropriate time delays, at an intensity several orders of magnitude higher than the drone would receive the signals from the satellites.

"What, our multimillion dollar RC aeroplane with super special awesome shooty bits on it got STOLEN? I thought those people were a bunch of camel riding nomads that didn't even have electricity! How did they spoof our GPS and jam our command and control feeds!?"
"Well sir, yes, the drone was actually stolen and not shot down. As for their offensive technical abilities sir, they *are* developing nuclear weapons, and most of their population is not comprised of nomadic camel riders, sir."
"Are you mockin' me son?! I've served in this god-blessed nation's armed forces muh entire life! And now you intend to tell me, that some turban wearin camel humpers not only defeated state of the art tactical surveylance like it was child's play, and didn't knock it down with rocks or summat', but that their so called nuclear program is actually viable, AND that my assessment of their "society" is plain and simply 'wrong'?!"
"No sir, I am not mocking you sir, but the rest of what you said is true sir."
"Get out of here private! I don't know who assigned you to technical liason, but they obviously picked a mo-ron. If I could demote you any lower than private, rest assured the orders would go through expediently!"
[I am probably (hopefully) wrong about this caricature, but this sure looks like how things are being run.]
The United States spends more on military toys and the US military in general than *all* of the other nations in the world *combined* (which includes Russia and China). Yet, as was shown in Viet Nam, as was shown in Iraq, and is being shown in Afghanistan, the US military, with all its high tech toys, can be defeated by simple, low-tech (and cheap) devices made up of 25 bucks of Radio Shack parts. The US military has it's "eye on the ball", yet it continues to over estimate its power and the effectiveness of its toys. Trillions of US dollars down the drain every year for military toys and invasions of other countries which pose absolutely no threat to the US, and for what? A false sense of security at best.
PublicIntelligence has a copy of an April, 2011 report identifying problems with drone communications including the risk of jamming and "lost link" events: http://publicintelligence.net/usaf-drones-in-irregular-warfare/
The old/new coke thing is when they phased in high fructose corn syrup instead of sugar.
The delay gave everyone long enough to forget what it was supposed to taste like...
Mexican coke still has sugar in it, and is best for mixed drinks. :)
Asking for "Mexican Coke" at Kroger's can give unexpected results, lol.

So, they spoofed GPS, jammed the drone's communications, then convinced it to land with the spoofed GPS coordinates. That's awesome.
Then, uhhh, why exactly did you guys have the kids from the Tehran High school football team and pep squad make up banners to hide the undercarriage?
Don't get me wrong. Both sides have plenty invested in having their own version of the story be the authoritative version, and the odds of the general public finding out the truth any time this decade are infinitesimal at best. But what we've been shown doesn't currently support the "we made it land on its own because we're fucking badass and the Americans suck" theory. It supports the "we don't want you to see what the underbelly looks like, also, we're lousy artists" theory. The iranians might have brought it down, and it might have crashed on its own while inside Iranian borders. "Proof" is in short supply at the moment.
There are some people that if they don't know, you can't tell 'em.
The last time I can recollect in this level of folly in aeronautics was in pre Vietnam days where the US got itself into a high level theory that manned flight and guns were no longer needed. It could all be done with missiles.
The theory wasn't entirely unsound. Nearly every air to air victory in the past decade has been via missile.
The problem was that during Vietnam, as many as half of the missiles didn't even ignite - they just fell to the ground inert. Of those that lit, fewer than half did anything other than fly in a straight line. And even if you had one a missile whose engine lit, the guidance tracked, and it was near the target - it's all for nothing if the explosives don't detonate. Pilots often ripple-fired 4-6 missiles at once, in the hope that one would work.
The reliability gained by almost 50 years of air to air missile development since Vietnam has changed the situation considerably.
The US and the West in general have suffered a disaster of large proportion. The technology was circumvented, and is now sat in the enemies hands. Soon it will be sold on to the Chinese and Russians, and the billions spend in the core research handed over to the enemy states for just about zero.
You're putting a lot of trust in a propaganda piece from a country with a perfectly reasonable score to settle. At this point, I'd say the Iranians are (and should be) playing the propaganda for all they can, espescially on the home front.
If you look at propaganda from the past century, you'd notice that the pattern is similar: Make a claim that "your team" outsmarted the enemy, and that's the reason for an event. It's pure BS, but that doesn't mean it won't play well for your allies and at the homefront.
These drones aren't purpose-designed to spy on low-tech countries. They're designed to be able to go into far more advanced countries (ie. Russia and China) that are more than capable of toying with GPS, and in fact, where altering and jamming GPS is expected.
Electronic warfare is 70+ years old at this point, and the questionable reliability of radio signals (espescially in the face of jamming) are well known. Being able to complete your mission with massive radio jamming is a requirement for anything that flies for the US military, and has been for generations.
We don't know whether the drone had inertial navigation or not - given the size and cost involved, there's no reason it shouldn't have inertial navigation - in fact, I find it hard to believe it doesn't use INS. US cruise and ballistic missiles use INS, as do warplanes - specifically because it's well-known that GPS can't be counted on.
If the drone does have INS (as well as terrain mapping, or both which is what I suspect), it's extremely unlikely that the Iranian story has even a hint of truth to it.
The paradoxical level of comedy that the Iranians just Stux'xxed a US drone out of the sky and onto their landing strips just makes the paradox a hilarious one.
That’s why I dont' believe it. Were it less comedic, I'd have no trouble with the story.
It's great political theatre, but it doesn't line up with what I know about the technologies involved. I've built robots for the military. While gimmicking GPS is doable, it's only a piece of the puzzle - and one that can be easily gamed. It makes for great propaganda, but it overlooks the other systems that have to be onboard for the thing to fly.
Drones have multiple independent means of determining its location, because GPS can't be counted on in a full-on war; it's one of the first things to fall in electronic warfare. INS is cheap, has been used for decades, and still is used because it can't be messed with externally. Terrain mapping is relatively new, but is also cheap to implement, and one of the drone's missions is to scan the terrain (with millimeter band radar).
So unless the Iranians somehow found a way to externally modify INS, as well as shift large-scale sections (at least a hundred square miles) geography of the region in real-time, the GPS story just doesn't hold up.
