The new theory comes just a few months after a damning "final" report on the doomed jet's mystery disappearance failed to determine exactly why it vanished.
The March, 2014, disappearance of the jet remains one of the history's greatest unsolved mysteries.
Jeff Wise, an aviation expert who has regularly appeared on CNN, told The Daily Star it would a "fairly straightforward" thing for hackers to accomplish.
He said: "I think it's hard to control 300-odd people. But it would be a fairly straight forward thing to depressurise the plane, and let the people suffocate.
"The idea is that if you get into the electronics bay, and you have access to computers that control the plane, you can do things like unlock the cockpit door.
He added: "You can unlock the cockpit door from the electronics bay. If there's a hijack under way the captain is going to lock the cockpit door.
"But if the captain is no longer in control of the plane, he's not in a good position."
Malaysia Airlines Flight MH370 took off from Kuala Lumpur and was heading to Beijing with 239 people on board.
But at 12.14am on March 8, 2014, Malaysia Airlines lost contact with MH370 close to Phuket island in the Strait of Malacca.
Before that, Malaysian authorities believe the last words heard from the plane, from either the pilot or co-pilot, was "Good night Malaysian three seven zero".
Satellite "pings" from the aircraft suggest it continued flying for around seven hours when the fuel would have run out.
Experts have calculated the most likely crash site around 1,000 miles west of Perth, Australia.
But a huge search of the seabed failed to find any wreckage – and there are a number of alternative theories as to its fate.
Various theories have been put forward, including that it crashed in the remote Cambodian jungle, and there was a cover-up involved.
However, pieces of the jet have washed up on the eastern coast of Africa, suggesting it did go down in the sea.
