Drones aren't just a hobby -- they're becoming an important part of fire fighting, search and rescue and policing. Nils Rodday worked with a drone manufacturer to find security holes in its unmanned flying vehicles.
© nasrul_effendy/RooM the Agency/CorbisDrones -- those fearsome unmanned flying vehicles that ignite debates about privacy and the ethics of warfare -- now have something to fear themselves. That would be Nils Rodday, a German cybersecurity student who proved he can hack a drone.
Rodday found flaws in one drone model that let him send commands to it from more than a mile away, showing how a hacker could become a pilot from the ground. But Rodday isn't a hacker himself. He doesn't even like the idea of being called a hacker.
"I have no intention of harming anyone," he said.
Instead, he was working with the drone manufacturer, whom he declined to name because of a legal agreement with the company, to help make the device more secure.
Unless they're on a preprogrammed flight, drones have to receive commands from the ground. Those commands come from a chip that broadcasts messages up in the air for over a mile through something called an XBee channel. Rodday found he could intercept the broadcasts and lea the language that controls the drone. He could then send messages to the drone over the same channel himself, taking over the virtual pilot's role.
As if we didn't have enough to worry about with drones, from fears of them crashing into us from the sky, to the chance they could be spying on us like a 21st century peeping tom. Now, there's the chance that the drones we should be able to trust -- the ones cops would use for law enforcement -- could end up being hijacked at the worst possible times. Thank goodness they're not armed. Yet.
Rodday did the research as part of a graduate program in Italy, and he presented his findings at the RSA cybersecurity conference in San Francisco on Wednesday. But he'd already made an impression with his work; he's now four months into a job with IBM.
The manufacturer Rodday worked with handed him a drone and a manual and let him see what he could find. Even though he had access to all the goods, the vulnerability he found could be exploited remotely by anyone with the knowledge of how to do it. The company has since fixed the problem, Rodday said.
Other drone manufacturers use the same chip to communicate commands to their high-flying products, Rodday found. He doesn't know if they have the exact same problem he pointed out in his research, but it's possible.
Many times when researchers find flaws in products, they say manufacturers see it as an attack. But Rodday said he was happy to work with a company that wanted him to break their toys to make them safer.
"I think they took the right point of view," Rodday said.
