Hong Kong-based Cathay Pacific Airways announced that the airline has discovered unauthorized access to the personal data of 9.4 million passengers.
Cathay Pacific said the data stolen included names, nationalities; birth dates, phone numbers, addresses, passport and identity card numbers and expired credit card numbers, among other information. It said no passwords were compromised. It was contacting customers to advise them on how to protect themselves.
Cathay Pacific became the target of the world’s biggest airline data breach.
Chief executive Rupert Hogg apologised and said there was "no evidence" the information had been misused.
It also said customers could contact the airline at infosecurity@cathaypacific.com.
The airline’s shares slumped to the lowest intraday level in nine years, shaving as much as $361 million off its market value.
