Malaysia Airlines site hacked by group claiming support for IS

Malaysia Airlines officials were struggling today to restore the embattled carrier's website after it was hacked by a group proclaiming support for Islamic State group.

The airline's site was changed, 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 trying to recover from twin disasters last year, including the disappearance of Flight 370, which authorities believed crashed 1,100 miles off Australia's west coast.

The website was later changed to a picture of a lizard, with the ISIS 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 and Microsoft's Xbox site.

In August, it also tweeted to American Airlines that there might be explosives on a plane carrying the president of Sony Online Entertainment, which makes video games, forcing the flight to be diverted.

Malaysia Airlines said in a statement that its domain name system was 'compromised' and users were being redirected to the hacker group's website. It said it will take up to 22 hours to restore the website.
