PETALING JAYA (THE STAR/ASIA NEWS NETWORK) - Malaysian International and Trade Industry Minister Mustapa Mohammad is among the passenger names listed on the itinerary leaked in the hacking of the Malaysia Airlines (MAS) website.

The group allegedly behind the website hacking has claimed to have compromised their user data and in a picture posted on their Twitter account.

Datuk Seri Mustapa, whose name was in the user data, had made a booking with MAS for Jan 26 from Subang to Kota Baru on a Firefly flight.

A passenger whose name and contact details were available on Lizard Squad's twitter account confirmed that he booked a flight.

"Yes, I booked a flight with MAS.

"I will call them to check if my booking has been compromised," he said when contacted by The Star Online on Monday.

In one of their tweets, the group mentioned that MAS was lying when the airline said the user data wasn't compromised.

"We would like to point out that @MAS is lying about user data not being compromised. Refer to earlier imgur link," they posted at around 2.18pm on Monday.

In another tweet, they warned that they would continue to hack MAS' servers.

"Going to dump some loot found on http://www.malaysiaairlines.com/ servers soon," said the tweet.

Earlier today, MAS confirmed that their Domain Name System (DNS) has been compromised where users are redirected to a hacker website when users access their website.

"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," said MAS in a press statement.

They have reported to CyberSecurity Malaysia and the Ministry of Transport on the matter and also assured customers and clients that this temporary glitch does not affect their bookings and their user data is secure.
