MH370 flight which was travelling from Kuala Lumpur to Beijing, suddenly disappeared on 8 March 2014, while 239 people were on board. The aircraft last communicated with the traffic controller when it was over the South China Sea and after that, it completely disappeared.
Investigations revealed that it changed its route and moved back to Malaysia. There were many theories at that time that the pilot Zaharie Shah might go on a suicide mission, fire may break out, or the plane was hijacked.
However, there was another theory which could be the case that a cyber attack which took place with the right tools and knowledge about the Boeing 777 can go through the cockpit and hack the system. There entertainment system on each seat of the aircraft is connected through a box. You can plug into the ports if you have the right connectors.
It is observed that through connecting to the box, you can then retaliate into any part of the aircraft, for example, the fuel management control, engine controls and many other systems.
Mr Roberts an ethical hacker has tried this method almost 20 times, and now he is banned from United Airlines flights. He deferred that he has no intentions to harm anyone, he wants to create awareness regarding possible cyber attack safety during flights.
However, Larry Vance an aviation expert disagrees. By saying “Unless a cyber hacker can hack into the brain of the pilot and make him do things he doesn’t want to do, I don’t see how it could affect the plane.”
