KUALA LUMPUR (Dec 10): Initial investigations into the data leak involving five million AirAsia passengers and staff found there was a cyberattack on AirAsia's server system on Nov 12 resulting from unauthorised access. Fahmi said the ministry views seriously allegations that the data leak was caused by a hacker group known as "Daixin". "Apart from that, data users should outline a cybersecurity policy, and ensure that the policy is followed as a measure to avoid intrusion by irresponsible parties," he said. Last month, local media reported that personal data of passengers and employees of the low-cost airline was allegedly leaked, after being hacked by the cybercrime group known as Daixin.
