All is relatively well here at Woesnotgone Meadow, where everyone has above average bandwidth. The temporary cold snap has gone away...for now. With those cold temperatures they made quite a few people think about flying somewhere warm, just not on Cathay Pacific.
Cathay Pacific is the Hong Kong based airline. Cathay Pacific also operates as their subsidiary Hong Kong Dragon Airlines Ltd.
The airline discovered the unauthorized access to their system. The attackers accessed the data of 9.4M passengers. This included their clients of the Marco Polo Club, Asia Miles, and other registered users. Although this was accessed, there was no evidence, so far, that the data had been misused. This is measured as the largest breach of data in the aviation industry. The was, arising from this issue, from the Hong Kong Privacy Commission, a “serious concern” regarding the data compromise.
As noted, there was the unauthorized access to the client’s data. One of the systems accessed may have been the customer resource management (CRM) system. This was suspected in March 2018. Based on this an initial review was completed, and the compromise was confirmed in May 2018. The detection, while pertinent in the scenario, occurred while they were working on “ongoing security processes”. The airline also worked with a cybersecurity firm to further the understanding of the compromise.
With the attack and compromise, there was an issue with the reporting. The reporting to the clients was delayed. During the interim, the clients were at risk for identity theft and a number of other crimes as their data was exposed. To assist with the remediation, the airline is providing identity/credit monitoring services from Experian.
The compromise appears to have allowed the attackers access to the client’s name, nationality, birth date, phone numbers, address, 860K passport identification numbers, travel data, and other data. There were no CVV numbers involved with the exfiltration. There were no passwords exfiltrated with this successful attack.
Externally, the Hong Kong office would initiate compliance checks. Also, to assist with the reporting to affected parties, the airline began to contact the parties through various methods, in comparison to depending on just one. The Hong Kong Privacy Commissioner has urged people to change their passwords and enable 2FA.
With such a large compromise, there would be an effect on the airline in some manner. Based on this the airline’s stock did decrease significantly (6.5%) on the Hong Kong Exchange. Fortunately, the flight operations were not affected by the compromise, as this was on a different system.
The attackers should not have access for this period of time. The attackers had full access to the payment system, unfettered, for months. It is estimated the attackers were internally active for at least seven months. This should have been noticed during this extended period. The company’s rationale for not reporting this sooner was they did not want to create an unnecessary fear. The InfoSec team should have been more in-touch with their enterprise activities and checked their logs.
Thanks for visiting Woesnotgone Meadow, where the encryption is strong, and the O/Ss are always using the latest version.
