Optus loses court bid to keep report into cause of cyber-attack secret

Josh Taylor reports a win for transparency:

Optus has lost a bid in the federal court to keep secret a report on the cause of the 2022 cyber-attack – which resulted in the personal information of about 10 million customers being exposed – after a judge rejected the telco’s legal privilege claim.

After the hack, the company announced in October last year that it had recruited consultancy firm Deloitte to conduct a forensic assessment of what had led to the cyber-attack.
