There are growing concerns about drone aircraft and cyber attacks, particularly a method known as "spoofing."

In June, researchers at the University of Texas successfully hijacked a drone with $1,000 worth of equipment. In July, lawmakers referenced the experiment during a meeting of the House Homeland Security Committee.

Drones remain a major growth industry despite a big fight over privacy, civil liberties, and regulation.

John Shore, information security analyst at Dynamics Research Corporation, discussed "spoofing" on Capital Insider.
