Millions of passengers hit in worst ever airline data hack


Cathay Pacific Airways Ltd said a hacker accessed personal information of 9.4 million customers, becoming the target of the world’s biggest airline data breach.
The airline’s shares sank the most in almost two years, shaving $201 million off its market value, after the Hong Kong-based carrier disclosed the unauthorised access, seven months after discovering the violation. While passports, addresses and emails were exposed, flight safety wasn’t compromised and there was no evidence any information has been misused, it said, without revealing details of the origin of the attack.
“This is quite shocking,” said Shukor Yusof, founder of aviation consulting firm Endau Analytics in Malaysia. “It’s probably the biggest breach of information in the aviation sector.”
Affecting more people than the population of Cathay Pacific’s home base of Hong Kong, the hack is in another league to breaches reported by British Airways Plc and Delta Air Lines Inc. this year. Those carriers boosted spending on cybersecurity after hacks, which saw personal and financial information of hundreds of thousands of customers illegally accessed.
“At this point, we believe it is uncertain if Cathay Pacific would be liable to any fines imposed by government authorities for such a breach,” Geoffrey Cheng, an analyst at Bocom International Holdings Co., wrote in a research note. “However, we expect the share price jitters to linger on for a while.”
The data breach at Cathay — a partner of British Airways in the Oneworld airline alliance — adds to the carrier’s woes, with Chief Executive Officer Rupert Hogg trying to turn it around after two straight annual losses.
“I’m truly sorry for the concern this may have caused you,” Hogg said, addressing customers in a video posted to the carrier’s website.
For the majority of people affected, the hackers accessed a combination of passenger name, and either phone number or email, Hogg said. No one’s travel, Asia Miles or Marco Polo Club loyalty program profiles were accessed in full, and no passwords were compromised, he said. Cathay Pacific is notifying affected passengers, and will provide free ID monitoring to those who request it, he said.
“Upon discovery, we acted immediately to contain the event and to thoroughly investigate,” Hogg said. “We engaged one of the world’s leading cybersecurity firms to assist us, and we further strengthened our IT security systems too.”
Shares of Cathay Pacific tumbled 3.8 percent in Hong Kong, the biggest loss since January 2017.

A dedicated website,, provides information about the event and what affected passengers should do next.
Some local lawmakers criticised Cathay for taking so long to reveal the breach. Lam Cheuk-ting, a member of the Legislative Council’s security committee, told reporters that many people in Hong Kong are angry and the airline should’ve taken the initiative the very first day it found out. Cathay’s Chief Customer and Commercial Officer Paul Loo said the airline wanted to have accurate grasp on the situation and didn’t wish to “create unnecessary panic,” AFP reported.
