Yesterday, New South Wales Police were alerted about a breach of the NSW Online Registry Website, a secure online platform that offers access to information involved in civil and criminal cases in state courts.
Thousands of sensitive court files, including apprehended violence orders and affidavits, were downloaded.
Investigators are still trying to establish the full extent of the breach.
Anybody who thinks their details may have been compromised is urged to make a report through ReportCyber.
