HONG KONG: The website of embattled Malaysia Airlines has been hacked by a group proclaiming support for Islamic State group.

The airline's site was changed on Monday, at first with a message saying “404 - Plane Not Found” and that it was “Hacked by Cyber Caliphate.”

The browser tab for the website said “ISIS will prevail.”

Malaysian Airlines is struggling to recover from twin disasters last year, including the mysterious disappearance of Flight 370 and Flight 17 which crashed after having been shot down near Ukraine.

The website was later changed to a picture of a lizard, with the IS reference removed and the claim of responsibility changed to “Lizard Squad - Official Cyber Caliphate.”

The Lizard Squad group last year claimed it was behind attacks on Sony's online PlayStation network.

The airline said on its Twitter account it was working on “resolving the issue.”
