Major Cyber Breach at NSW Health Exposes 100,000 Documents A hacker claims to have breached an isolated NSW Health server, stealing approximately 100,000 sensitive documents totaling around 70GB. The breach was reported to authorities on October 30, 2026, and has been classified as a major incident. Cyber Security NSW confirmed that no patient data has been compromised, and the investigation is ongoing under Strike Force Civic. The hacker, known as 'bytetobreach', allegedly exploited a misconfigured subdomain to access the data before crashing the server. Authorities are working closely with NSW Police Cyber Crime Squad to investigate the incident. The hacker has made no ransom demands, suggesting motives may include notoriety within hacking communities. The breach is still under investigation, and further details are pending verification. 13 sources 53
