description: "NSW Health found unauthorized access on Oct 29 to a single isolated server running its Oral Health Fee For Service Scheme website, a voucher scheme for subsidised dental care from outside providers. Cyber Security NSW declared it a major incident. Officials say no patient data was affected and no clinical services are at risk. NSW Police say a 'significant amount' of personal identification information about the third-party providers (mainly dentists), about 4GB, was taken, that the suspects are outside Australia, and that someone has posted a claim of responsibility online. No ransom demand had been received."

### NSW Health declares a 'major incident' after about 4GB of dentists' personal data was taken from its Oral Health Fee For Service Scheme website

If you are a dentist or practice enrolled in the scheme, expect targeted phishing or identity fraud that uses your registration details, and watch for official notification from NSW Health. Police are investigating under Strike Force Civic with the AFP, and have been in touch with the FBI and DHS.
