The current radar-based air traffic control system will eventually be replaced with a new system called NextGen, which will rely on GPS. A number of computer security experts are concerned that NextGen is insecure and vulnerable to hackers.
The Federal Aviation Administration is in the midst of a multibillion-dollar upgrade of the nation’s air traffic control system. The new system is called the Next Generation Air Transportation System, or NextGen. It will be highly automated. It will rely on GPS instead of radar to locate planes, and it is designed to allow air traffic controllers and pilots to pack more planes, helicopters and eventually drones into our skies.
But a number of computer security experts are concerned that the cornerstone of NextGen is insecure and vulnerable to hackers. [More…]
The FBI responds to a brief computer outage at their Cyber-Security Division by tracing down top computer hackers, finding several of them have been killed. Taking others into protective custody, the FBI orders NYPD detective John McClane (Bruce Willis) to collect Matthew “Matt” Farrell (Justin Long). McClane arrives in time to prevent Farrell from being killed by an assassin, Mai Linh (Maggie Q), working for Thomas Gabriel (Timothy Olyphant). On route to Washington DC, Farrell explains he had written a portion of security code for a large sum of money from Mai.
As they arrive in DC, Gabriel orders his own crew of hackers to take control of the transportation grids and stock market, while nationally broadcasting a message threatening the United States. Farrell recognizes this as the start of a “fire sale”, an attack designed to target the nation’s reliance on computer controls, such that “everything must go”. [source]
