Cathay Pacific announced last week the airline’s standard security processes recently discovered a data breach impacting the passenger data of 9.4 million customers.

According to Cathay Pacific, the airline took immediate and decisive action to contain and investigate the breach. A statement from the airline indicates there is no evidence that shows any data was misused. The information technology systems targeted are totally separate from the flight operations systems.

“We are very sorry for any concern this data security event may cause our passengers. We acted immediately to contain the event, commence a thorough investigation with the assistance of a leading cybersecurity firm, and to further strengthen our IT security measures,” said Rupert Hogg, CEO, Cathay Pacific.

Affected data includes passenger names, nationalities, dates of birth, phone numbers, passport numbers, frequent-flyer membership numbers, customer service remarks and historic travel information. In addition to this travel information, 403 expired credit card numbers were accessed and 27 cards with no security code were collected.

“We want to reassure our passengers that we took and continue to take measures to enhance our IT security. The safety and security of our passengers remains our top priority,” Hogg added.
