Qantas has sent emails to customers affected or potentially affected by a cyber attack, but none of its executives have yet fronted the media.

Qantas is contacting customers after a cyber attack targeted their third-party customer service platform. On 30 June, the Australian airline detected "unusual activity" on a platform used by its contact centre to store the data of six million people, including names, email addresses, phone numbers, birth dates and frequent flyer numbers.

Qantas working with cyber security experts, analyse the impacted system, and put new security measures following this week's data breach.
