Pacnet, a subsidiary acquired by Telstra in April 2015, was hit by a major data breach affecting thousands of customers including The Australian Federal Police and government agencies. The breach occurred two weeks before the deal to acquire Pacnet by Telstra was finalised but was not disclosed to Telstra. Telstra is reportedly considering its legal options in respect of both the breach and the non-disclosure by the vendors.
