A company that issues Aviation Security Identity Cards has been hacked, leading to concerns that Australian airport security may have been compromised.
The identity cards are designed to stop organised criminals and terrorists from accessing planes and other restricted airport zones.
Hundreds of people applying for, or renewing their cards through NSW-based company Aviation ID Australia received emails on Wednesday telling them their application information, including name, street address, and Medicare card number may have been stolen.
The Australian Federal Police has confirmed it is investigating the hack.
