The official website of Malaysia Airlines has been attacked by hackers claiming to be from the Lizard Squad, a group known for previous denial-of-service incidents.
The website displayed on Monday morning the photo of a lizard wearing a monocle and smoking a pipe, which has become the group’s trademark.
The main page showed the words '404 – Plane not found' and 'Hacked by Lizard Squad – Official Cyber Caliphate'. For a brief moment the browser tab also read 'ISIS will prevail' according to various media reports, sparking concern over the group’s support for the militant group.
Malaysia Airlines confirmed in a statement that its site was “compromised” but it did not affect bookings or temper with customers’ personal data.
The national carrier said that the issue has been resolved by its service provider “and the system is expected to be fully recovered within 22 hours”.
Commonly, when a website cannot be loaded, an error message saying '404 Page not found' appears.
The airline was faced with two major aviation disasters last year, the disappearance of flight MH370 with 230 people aboard and the shooting down of flight MH17.
Lizard Squad later took to Twitter and warned that it would release data from Malaysia Airlines, without specifying what information they had.
Microsoft and Sony networks suffered outages on Christmas Day after a denial-of-service prevented millions of users logging on, which was also claimed by the hacker group Lizard Squad.
