Todays topic. GPS Spoofing A GPS spoofing attack attempts to deceive a GPS receiver by broadcasting counterfeit GPS signals, structured to resemble a set of normal GPS signals, or by rebroadcasting genuine signals captured elsewhere or at a different time. These spoofed signals may be modified in such a way as to cause the receiver to estimate its position to be somewhere other than where it actually is, or to be located where it is but at a different time, as determined by the attacker. One common form of a GPS spoofing attack, commonly termed a carry-off attack begins by broadcasting signals synchronized with the genuine signals observed by the target receiver. The power of the counterfeit signals is then gradually increased and drawn away from the genuine signals. It has been suggested that the capture of a Lockheed RQ-170 drone aircraft in northeastern Iran in December, 2011, was the result of such an attack. GPS spoofing attacks had been predicted and discussed in the GPS community previously, but no known example of a malicious spoofing attack has yet been confirmed.A proof-of-concept attack was successfully performed in June, 2013, when the luxury yacht White Rose was misdirected with spoofed GPS signals from Monaco to the island of Rhodes by a group of mechanical engineering students from the Cockrell School of Engineering at the University of Texas in Austin. The students were aboard the yacht, allowing their spoofing equipment to gradually overpower the signal strengths of the actual GPS constellation satellites, altering the course of the yacht. en.wikipedia.org/wiki/Spoofing_attack
