Australia telecom giant Optus has been hit by a massive data breach by hackers. Following a cyberattack, Optus is investigating the possible unauthorised access of current and former customers’ information. The company has released a statement notifying its customers of the cyberattack compromising customer information.

According to the statement, upon discovering the cyberattack, Optus immediately shut down the attack and is working with the Australian Cyber Security Centre to mitigate any risks to customers. Optus has also notified the Australian Federal Police, the Office of the Australian Information Commissioner and key regulators.

“We are devastated to discover that we have been subject to a cyberattack that has resulted in the disclosure of our customers’ personal information to someone who shouldn’t see it,” said Kelly Bayer Rosmarin, Optus CEO.

We are very sorry and understand customers will be concerned. Please be assured that we are working hard, and engaging with all the relevant authorities and organisations, to help safeguard our customers as much as possible.”
