The company has taken immediate measures to investigate the data breach further. So far, Cathay hasn’t found any evidence of misuse of personal information. The airlines also mentioned that because of the recent data breach, part of the IT security processes have been affected, but and is the flight operations systems which are insulated from the IT security systems remain uncompromised.  

Cathay Pacific posted about the data breach on Twitter:

“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.

Cathay is currently contacting the affected passengers, using multiple communications channels, and is providing them with information on steps that can be taken to protect users.

“We have no evidence that any personal data has been misused. No-one’s travel or loyalty profile was accessed in full, and no passwords were compromised. Cathay Pacific has notified the Hong Kong Police and is notifying the relevant authorities. 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 remain our top priority”, said Hogg.
