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
American researchers took control of a flying drone by “hacking” into its GPS system – acting on a $1,000 (£640) dare from the US Department of Homeland Security (DHS).
The same method may have been used to bring down a US drone in Iran in 2011.
Analysts say that the demo shows the potential danger of using drones.
Drones are unmanned aircraft, often controlled from a hub located thousands of kilometres away.
They are mostly used by the military in conflict zones such as Afghanistan.
Todd Humphreys and his colleagues from the Radionavigation Lab at the University of Texas at Austin hacked the GPS system of a drone belonging to the university.
They demonstrated the technique to DHS officials, using a mini helicopter drone, flown over a stadium in Austin, said Fox News, who broke the story.
“What if you could take down one of these drones delivering FedEx packages and use that as your missile?” Fox News quoted Mr Humphreys.
“That’s the same mentality the 911 attackers had.”
