Malaysia Airlines claimed Monday that its website had not been hacked, refuting claims by hacker group "Lizard Squad," who appeared to have taken over the main page earlier in the day and made references to the Islamic State.
The carrier admitted that its Domain Name System (DNS) has been compromised resulting in users being re-directed to a hacker website when the www.malaysiaairlines.com URL is keyed in, but maintained that its database is secure.
"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," the airline said on its Facebook page on Monday afternoon.
The system is expected to be fully recovered within 22 hours, Malaysia Airlines said, noting that the incident was reported to CyberSecurity Malaysia and the Ministry of Transport.
Early Monday, many visitors attempting to access the airline's websites were re-directed to a page with the words "404 – Plane Not Found, Hacked by Cyber Caliphate" in bold white letters, against the backdrop of a Malaysia Airlines plane.
Earlier this month, the U.S. Central Command's Twitter and YouTube accounts were the targets of a cyber-attack by hackers that claimed to be working for Cyber Caliphate.
