Personal details of over 132,000 Telstra customers were recently made available by the Australian telco giant.
This included some customers’ names, phone numbers, and addresses.
Telstra said they became aware of the “error” in the “past few weeks”. It was not a result of a cyberattack.
In a message apologising to customers, Telstra’s Chief Financial Officer Michael Ackland said that people impacted would be contacted, and that an internal investigation into the event was underway.
Telstra has removed the majority of wrongly-placed information from their platforms, and is expected to complete this in the coming days.
“We’re sorry it occurred, and we know we have let you down… We acknowledge that we still get it wrong too often and we simply must do better,” Ackland said.
