Australia’s largest telecoms operator Telstra in early October suffered what it called a small data breach, which exposed data of about 30,000 current and former employees dating back to 2017.

On Dec. 11, Telstra said 132,000 customers were affected by an internal error which led to the disclosure of certain customer details.
