More than nine million customers of the airline Cathay Pacific have had their personal information, including passport numbers and credit card details, stolen by hackers. Identity card numbers, physical addresses and emails were stolen too.

Cathay Pacific says there's no evidence any personal information has been misused. But what's raising eyebrows is that the airline first discovered suspicious activity on its system back in March, but has only now chosen to make the hack public.

Computer security expert Graham Cluley says an announcement should have been made earlier.
