"abcGraduate students from the University of Texas who hijacked a civilian drone aircraft have demonstrated just how easy it would be to redirect unmanned vehicles—so-called UAVs that someday may do everything from delivering pizza to our doorstep to tracking stolen cars and aiding law enforcement. The hijacking was done over White Sands, New Mexico, at the request of the U.S. Department of Homeland Security. Officials with the department wanted to know if the students could actually do it. They did. The department has been reluctant even to talk about it. And the professor behind the capture has mixed emotions."

"wiredOn the evening of June 19, a group of researchers from the University of Texas successfully hijacked a civilian drone at the White Sands Missile Range in New Mexico during a test organized by the Department of Homeland Security. The drone, an Adaptive Flight Hornet Mini, was hovering at around 60 feet, locked into a predetermined position guided by GPS. Then, with a device that cost around $1,000 and the help of sophisticated software that took four years to develop, the researchers sent a radio signal from a hilltop one kilometer away. In security lingo, they carried out a spoofing attack. “We fooled the UAV (Unmanned Aerial Vehicle) into thinking that it was rising straight up,” says Todd Humphreys, assistant professor at the Radionavigation Laboratory at the University of Texas."

todd_drone"aasAfter a dress rehearsal at Royal-Memorial Stadium, University of Texas researchers traveled to New Mexico last month and demonstrated for U.S. Department of Homeland Security officials how an unmanned aerial vehicle, or drone, can be commandeered by hacking into its navigation system.

The technique, known as spoofing, created false Global Positioning System signals that tricked the drone's GPS receiver into steering a new course.

The Global Positioning System, which uses satellites and radio signals, is not encrypted for civilian uses, and that raises concern about the federal government's plan to permit thousands of drones in U.S. air space for commercial, law enforcement and university purposes, said Todd Humphreys, an assistant professor in UT's Cockrell School of Engineering. "The dirty fact is it's an open signal, and easily hacked," Humphreys said."

They were able to hack into the GPS signals of the drone, not only manipulating its flight path while flying over White Sands, New Mexico, but later landing it. Humphreys told CBS News, "You can think of this as hijacking a plane from a distance. (It's) as if you're at the controls of the plane, because you've now captured the autopilot's sense of its own navigation solution. And you can manipulate it left or right, up or down."

slashdot"The BBC is reporting that researchers from the University of Texas at Austin managed to hack an experimental drone by spoofing GPS signals. Theoretically, this would allow the hackers to direct the drone to coordinates of their choosing. 'The spoofed drone used an unencrypted GPS signal, which is normally used by civilian planes, says Noel Sharkey, co-founder of the International Committee for Robot Arms Control. "It's easy to spoof an unencrypted drone. Anybody technically skilled could do this - it would cost them some £700 for the equipment and that's it," he told BBC News. "It's very dangerous - if a drone is being directed somewhere using its GPS, [a spoofer] can make it think it's somewhere else and make it crash into a building, or crash somewhere else, or just steal it and fill it with explosives and direct somewhere. But the big worry is — it also means that it wouldn't be too hard for [a very skilled person] to work out how to un-encrypt military drones and spoof them, and that could be extremely dangerous because they could turn them on the wrong people."

Suddenly, the drone veers dramatically off course, careering eastward from its intended flight path. A few moments later, it is clear something is seriously wrong as the drone makes a hard right turn, streaking toward the south. Then, as if some phantom has given the drone a self-destruct order, it hurtles toward the ground. Just a few feet from certain catastrophe, a safety pilot with a radio control saves the drone from crashing into the field.

bloomberg"Two years ago, a new global positioning system-based system guiding jets to runways at Newark Liberty International Airport began switching off without warning. The culprits, according to government documents, were drivers on the adjacent New Jersey Turnpike who were using cheap, illegal GPS jamming devices to prevent their employers from locating them. The devices, whose signals are as much as 1 billion times more powerful than GPS transmissions, were also blanking out the airport landing system. That passing vehicles could so easily cripple airport navigation illustrates one of the U.S. Federal Aviation Administration’s obstacles in its $42 billion effort, known as NextGen, to convert the nation’s air-traffic control away from radar to a reliance on GPS. Wireless networks, financial institutions and power grids are also vulnerable to GPS disruption, according to studies commissioned by the U.S. government and academic experts. “The interference threats to GPS are very real and promise to get worse,” the National Space-Based Positioning, Navigation and Timing Advisory Board, which is appointed by the government, said in a 2010 report. So-called spoofers may be a greater threat than jammers. They mimic signals from space and can trick a receiver into displaying the wrong location, Todd Humphreys, an assistant engineering professor at the University of Texas, said in phone interviews. “The mischief makers are looking for opportunities to prick us in our soft spots,” he said. “This is a soft spot and a pretty glaring one.”

Austin, TX — Daniel Shepard and Sydney Norrell offered visitors to the UT campus a chance to get hands on with high-tech GPS receiver processing during Explore UT, the biggest open house in Texas. The RNL exhibit featured a chance to draw 3D shapes and figures with a GPS antenna that were then displayed on screen. The GPS signal processing leveraged an advanced signal processing technique called carrier-phase differential GPS.

TEDxAustinPhototedAustin, TX — What's the predictable endpoint of the trend toward ever cheaper, ever smaller, and ever more sensitive GPS?  It's the GPS dot: a GPS tracking device first featured in the movie "The Da Vinci code" and now moving inexorably from fiction to non-fiction.  The GPS dot will fundamentally re-order our lives.  We'll buy dots in bulk and stick them on everything we own worth more than a few tens of dollars.

But there is a dark side to the dot.  Did you know that it's not illegal to track your family, your friends, or even your ex-girlfriend/boyfriend with a GPS dot?  The lack of effective legal means of protecting ourselves from an invasion of GPS dots will lead to use of subversive tools for protecting our personal space, such as GPS jammers and spoofers.  A rise in the use of these illicit tools has the potential to wreak havoc on the "good" GPS receivers -- those built into our critical systems and infrastructure. The result: A looming showdown between privacy and GPS integrity.

What if you could use GPS technology to find your misplaced keys? How about if you could use that same technology to lie about where you were in the world or misdirect cruise ships? Dr. Todd Humphreys of the University of Texas at Austin's Radionavigation Lab paints a picture of an utterly new future at once worrying and fascinating.

Washington, D.C. — Dr. Humphreys briefed the National Space-Based Positioning, Navigation, and Timing (PNT) Executive Committee (EXCOM) Advisory Board on civil GPS spoofing.

Understanding Potential Impacts to Infrastructure," highlighted the Radionavigation Lab's radionavigation security research including the RNL civil GPS spoofer (video) and a proposal for GNSS message authentication.

splinter_meeting

sec_meet_pdf_thumb
Background: The Global Positioning System has been a marvelous success over the past three decades. One consequence of this success is a deepening dependence of the civil infrastructure on GPS—especially for timing synchronization. As civil dependence on GPS grows, the potential for financial gain or high-profile mischief combine to make denial or manipulation of GPS a clear and present risk. European researchers and officials are as concerned about GNSS security as their U.S. counterparts. The launch of Galileo will not solve the navigation and timing security problem because, like civil GPS, the Galileo open service—projected to be by far the most commonly used—will be susceptible to jamming and spoofing.


Goals: European and U.S. researchers and interested observers met in Portland, Oregon in Sepetember 2010 to discuss civil navigation and timing security threats and strategize about (1) how policymakers and manufacturers can be persuaded to take these threats seriously, (2) how to identify effective countermeasures, and (3) how to promote adoption of effective countermeasures.

Discussion Notes (provided by Brent Renfro, ARL)

Dr. Humphreys talked with the BBC radio show, "The Naked Scientists," about potential GNSS vulnerabilities.

Helen: So this sounds to me a little bit like when we had computers and we didn’t yet know anything about computer viruses. Almost that there’s a potential for someone to come along and mess around with the GPS and potentially cause some problems. But so far, we’re okay and the idea is that we should be pre-empting those problems

Todd: That’s right and the analogy with computers is a good one. There was a time, perhaps 20 years ago or more when we didn’t have to worry about computer security. But that time has passed and now we’re realizing that we must also pay attention to navigation and timing security.
