A new study has revealed that the Global Positing System (GPS) is vulnerable to hackers or terrorists. Because they can use it to hijack ships and commercial airliners. The new study has exposed a huge hole in national security.

GPS expert Todd Humphreys and his team at the University of Texas (UT) had taken over the sophisticated navigation system on a super-yacht in the Mediterranean Sea using a laptop, a small antenna and an electronic GPS spoofer, built for only 3,000 dollars. The UT team was able to drive the ship far, take it into treacherous waters, and even put it on a collision course with another ship.
