Malaysia Airlines official website has been attacked by hackers claiming to be from the “Lizard Squad – Official Cyber Caliphate”.

The national carrier’s homepage currently shows a photograph of a lizard in a top hat and tuxedo.

Malaysia Airlines has confirmed its website was compromised but said customers’ bookings and data were not affected.

The airline is still recovering from two disasters; the disappearance of MH370 and shooting down of MH17.

On January 26, the main page of its website was replaced by the words “404 – Plane Not Found” and “Hacked by Lizard Squad”.

“404 Page not found” is the common error message displayed when a website cannot be loaded.

Initially the words “ISIS will prevail” appeared in the browser tab for the page, but that has since disappeared.

It is not clear why Malaysia Airlines has become the target of a cyber attack or what connection the hack has to Islamic State, the militant group sometimes referred to as ISIS which has declared an Islamic caliphate in parts of Syria and Iraq.

Lizard Squad claimed on Twitter that it would release data from Malaysia Airlines, but did not specify what information it might have.

Malaysia Airlines confirmed in a statement that its “Domain Name System (DNS) has been compromised where users are re-directed to a hacker website”.

However, it said its own web servers were intact and the website itself had not been hacked into.

It said “this temporary glitch does not affect [customer] bookings” and user data “remains secured”. It added that it would take 22 hours to restore the website.

The hacker group Lizard Squad previously claimed to have disrupted Sony and Microsoft operations, with gamers unable to log on to XBox Live and PlayStation platforms over Christmas.
