Specialists from IOActive announced the discovery of a security vulnerability in the entertainment systems that are used by 13 major airlines on airplanes. A breach in the Panasonic Avionics system installed in airline liners (among them Emirates, Virgin Atlantic and Qatar Airways) can allow attackers not only to obtain data to classified information, but also to take control of the aircraft during the flight. The platform developed by Panasonic Avionics is used in entertainment systems in the backs of passenger seats. According to security consultant Ruben Santamarta, during a flight from Warsaw to Dubai, he managed to get to the debugging codes directly through the display of the entertainment device and gain access to the data of regular airline customers, as well as intercept messages and notifications. His plans were not to get control over the control of the aircraft, but if desired, it was quite feasible. Therefore, IOActive employees reported the vulnerability of the on-board Panasonic system, however, it is not known whether the company took measures. As security experts emphasize, developers of on-board and entertainment systems for vehicles should be especially vigilant and constantly improve software. A sufficiently skilled attacker can carry out a cyberattack directly from the liner, and therefore it is worth taking care of isolating the entertainment system on board.
