Singtel's Optus appoints Deloitte to review cyberattack

The review will include a forensic assessment.

Singtel's subsidiary Optus appointed Deloitte to conduct an independent external review of the recent cyberattack it faced.

In a bourse filing, Singtel said Deloitte will conduct a forensic assessment of the cyberattack and the circumstances surrounding it.

Optus CEO, Kelly Bayer Rosmarin, said the review will help the company understand how the attack happened and how they can prevent it from occurring again.

"It will help inform the response to the incident for Optus and may also help others in the private and public sector where sensitive data is held, and risk of cyberattack exists," Rosmarin added.

Singtel earlier said the cyberattack has possibly exposed customer information such as names, dates of birth, phone numbers, and email addresses.
