(Bloomberg) -- Months after Cathay Pacific Airways Ltd. first detected the world’s worst airline data breach, the carrier is still counting costs from the attack.

Answering queries from Hong Kong’s lawmakers at a panel meeting Wednesday, Chief Executive Officer Rupert Hogg said it’s still too early to discuss compensation and costs arising from the hack’s fallout. The city-based carrier is also facing inquiries in 15 jurisdictions, he said, without elaborating.

Cathay Pacific, which disclosed the breach in an Oct. 24 filing after discovering the violation in March, is increasingly under fire for the delay in informing regulators and passengers. While the attack exposed personal information of 9.4 million passengers, including passport details, addresses and emails, Asia’s biggest international airline said flight safety wasn’t compromised and there was no evidence the data was misused.

The sophisticated attacks were most intense March through May and continued, Cathay said Monday separately. Although the number of successful attacks diminished, concerns remain “new attacks could be mounted,” it said.

Chairman John Slosar told lawmakers that the carrier made a call in March that the information, although of public interest, wasn’t material or price sensitive and held off on disclosing it immediately. Cathay has said in the past that it needed to investigate the violation thoroughly before sharing details of the attack.

Shares of the carrier have rebounded 3.4 percent since the disclosure. They had slumped the most since January 2017 the day after the filing.

The breach has prompted calls to overhaul Hong Kong’s two-decades-old privacy laws to ensure companies report any leaks quicker. For now, offenses for disclosing personal data obtained without consent from users could be subject to a fine of HK$1 million and imprisonment for five years, according to the Personal Data Ordinance. Individuals who suffer damage could also seek compensation.
