The flight itinerary of International and Trade Industry Minister Datuk Seri Mustapa Mohamed was among the information leaked by a hacker group after it allegedly hacked the Malaysian Airlines' (MAS) website this morning.

The group posted an image on Twitter which seemed to be a screen capture taken from MAS e-mail.

The image showed Mustapa's name listed in the booking system for a trip from Subang Airport to Kota Bharu on January 26, 2015.

The Malaysia Airlines' official website has been hacked - twice in a span of 30 minutes.

At 10am this morning, netizens trying to enter the URL www.malaysiaairlines.com were directed to a page with an image of a Malaysia Airlines plane.

“404 – Plane Not Found. Hacked by Cyber Caliphate. Follow Cyber Caliphate on Twitter,” reads the text on the page.

The website then appeared to be fine, but was followed by another hack.

At 10.25am, an image of a suited lizard appeared on the page with the same text.

MAS in a statement today said that the system is expected to be fully recovered within 22 hours.

The airline also gave an assurance that all of its web servers are intact and that the 'temporary glitch' does not affect the customers' bookings and their data remain secured.
