Notifiable data breaches
Under the Notifiable Data Breaches scheme, your organisation may have notification obligations when a data breach is likely to result in serious harm to any individuals whose personal information is involved in the breach.

To understand your obligations under the Notifiable Data Breaches scheme, and to separately report a data breach to the Office of the Australian Information Commissioner, see their Notifiable Data Breaches scheme page.
Individual Australians should report cyber security incidents to the Australian Cybercrime Online Reporting Network (ACORN). ACORN is a secure reporting and referral service for cybercrime and any online incidents that may be in breach of Australian law.

Thank you for reporting to the ACSC. Your report will help to make Australian networks harder to compromise in the future.

A member of staff will contact you should your report require action or clarification.

Your report helps the ACSC to develop a better understanding of the threat environment and may assist other organisations that may also be at risk.

Cyber security incident reports are also used in aggregate for developing new defensive policies, procedures, techniques and training measures to help prevent future incidents.

Finally, a reminder that your organisation may have notification obligations when a data breach is likely to result in serious harm to any individuals whose personal information is involved; see the Office of the Australian Information Commissioner Notifiable Data Breaches scheme.
