Notorious hacker group, Lizard Squad, which took down Xbox Live and Sony PlayStation Network in December 2014, have claimed responsibility for the cyber attack on Malaysia Airlines' website.

As at yesterday, Janaury 26, 2015, the website displayed a picture of a lizard in a top hat, monocle and pipe between its lips, as well as the text: '404-Plane Not Found' (a reference to flight MH370, which disappeared in March), and 'Hacked by LIZARD SQUAD-OFFICIAL CYBER CALIPHATE.'

The website has since been restored. It is still unclear whether or not Lizard Squad is actually linked to Cyber Caliphate, a hacker group that claims to be associated with ISIS.

Earlier this month, Cyber Caliphate took control of the U.S. central military command's Twitter and YouTube accounts.

Officials of Malaysia Airlines confirmed the attack on the company's Facebook page:

"Malaysia Airlines confirms that its Domain Name System (DNS) has been compromised where users are re-directed to a hacker website when URL is keyed in. At this stage, Malaysia Airlines’ web servers are intact. The airline has resolved the issue with its service provider and the system is expected to be fully recovered within 22 hours.

"The matter has also been immediately reported to CyberSecurity Malaysia and the Ministry of Transport. Malaysia Airlines assures customers and clients that its website was not hacked and this temporary glitch does not affect their bookings and that user data remains secured."

However, Lizard Squad via a tweet, claimed it had some materials taken from Malaysia Airlines' servers. It had already shared a screenshot of an inbox with passenger itineraries.

The group has also claimed responsibility for the outage of Facebook, Instagram, Tinder, AIM and MySpace which happened earlier this morning.
