Telstra’s data breach occurred on Friday when its customer service website was openly accessible on the Web. Account numbers, phone numbers and credit card details of just fewer than one million Telstra customers were potentially compromised by the breach. Telstra said it was made aware of a privacy breach about 4pm (AEDT) on 12 December and disabled its online billing, BigPond self-care and My Account functions on its website an hour later. As a precaution, the company reset the passwords of around 60,000 customers and notified the Privacy Commissioner.”]
