Data breach: Telstra error exposes details of 132,000 customers in Australia

Telstra, which has 18.8 million customer accounts equivalent to three-quarters of Australia’s population, said an internal review found the details were made publicly available due to “a misalignment of databases”. The errant disclosure comes after the company in October suffered what it called a small data breach, attributing it to third-party intrusion that exposed some employee data back to 2017.
