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 US$201mil (RM837.82mil) off its market value, after the Hong Kong-based carrier disclosed the unauthorised access late Oct 24, 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.
